Technical Field

The invention provides a light-weight, non-bulky and excellent-warmth-retention laminated fabric for clothing and a method for producing the same.

Background

Conventionally, down feathers (feathers) and bird feathers (wing feathers) (hereinafter, referred to as "feathers") of birds such as ducks and geese have been widely used for down jackets and down jackets because of their light weight, high heat retention, and excellent moisture absorption and scattering properties.

In general, feather products such as clothes and bed products using feathers are filled with feathers between a surface layer fabric and a back layer fabric, but because of the nature of feathers, they are not uniformly dispersed and disposed because they are locally displaced, and therefore, a sufficient effect cannot be obtained for the entire product, and this is not preferable in terms of appearance.

Therefore, it is conceivable to carry out a quilting process in which the surface layer fabric and the back layer fabric are sewn at a predetermined interval, thereby preventing the feathers from being largely displaced and uniformly arranging the feathers as a whole.

However, since feathers are light and are extremely thin, they have a problem that they come out from gaps between fibers of the surface layer fabric or the back layer fabric or from pinholes formed by sewing the surface layer fabric and the back layer fabric at the time of quilting. Emergence of feathers can cause allergic dermatitis, bronchial asthma or rhinitis.

Therefore, in order to solve this problem, a high-density fabric is sandwiched between rollers, and a strong pressure and a high temperature are applied to crush and narrow gaps between threads to prevent feathers from coming out, or a fabric subjected to a feathering prevention process in which gaps between threads are coated with a resin or the like to fill the gaps is used to prevent feathers from coming out.

However, the fabric subjected to such processing has poor air permeability, poor moisture absorption and dispersibility, and is hardened and heavy under the influence of a coating agent, and even if the fabric subjected to such processing is subjected to such processing, feathers are not completely prevented from emerging from pinholes in the stitched portion between the surface layer fabric and the back layer fabric. Therefore, various techniques have been devised so far for preventing feathers from popping up.

One of the methods widely used is to accommodate feathers in a bag-like middle fabric called a "feather bag" and to sandwich the feather bag in a space formed by sewing a surface fabric and a back fabric, thereby reducing the weight and preventing the feathers from coming out.

Further, for example, japanese patent application laid-open No. 2002-173815 discloses: a down jacket for preventing feathers from coming out is characterized in that a filling part is formed, a surface fabric is overlapped to sew the center of 2 seams, then feathers are filled in the filling part of a middle fabric, and a bottom fabric is overlapped to sew the peripheral part of the fabric, wherein the filling part is formed by overlapping a plurality of middle fabrics, sewing a plurality of parts at the 2 seams and opening both ends (patent document 1).

Although this is a method of preventing the wing feathers from coming out of the seams by shifting the positions of the seams of the middle fabric and the seams of the surface fabric, even if the technology of patent document 1 is held, it is said that "the raw materials of the middle fabrics 1 and 2 may be any raw materials such as synthetic fibers, natural fibers, or blends or interlaces thereof, but it is preferable to use the fabrics subjected to the anti-fluff processing. In short, except for the fabric subjected to the down-proof processing, feathers cannot be completely prevented from emerging.

When a fabric subjected to a lint-proof process is used, as described above, the moisture absorption and air permeability are inevitably deteriorated, and the overall weight is increased.

In addition, Japanese Utility model laid-open publication No. 02-101727 discloses: (1) the feather packaging raw material is formed by melting feathers on one side or two sides of the non-woven fabric. (2) And melting the feathers on one side of the non-woven fabric, and melting the double-folded hot spots to form the feather packaging raw material. (patent document 2). According to the feather packing material, the feathers are fixed on the non-woven fabric, so the feathers can not penetrate through the fabric, the fabric with soft seams is not required to be used for manufacturing the middle bag, the common fabric can be directly used for manufacturing cold-proof clothes, bedding and the like which are full of the feathers, and in addition, the feathers are fixed, so the feathers can not scatter and are extremely easy to collect.

When the technique of patent document 2 is used for clothes such as a down jacket, the technique can be used as a down bag to be inserted between a surface fabric and a back fabric, and the down bag is formed of a nonwoven fabric, and feathers can be prevented from coming out by melting the nonwoven fabric.

Disclosure of Invention

However, the feather products such as the down quilt and the down jacket are characterized in that the volume is enlarged for enhancing the hand feeling of the feather, and it is said that the feather is soft, light, warm-keeping and moisture-keeping because of the enlarged volume.

However, the feather product has a large volume, and therefore, the feather product has a large volume when worn, and therefore, the feather product is clumsy to move, and is difficult to be collected when stored in other than winter or when taken off from a place.

In addition, as described above, in the case of inserting a stuffed bun, there is a problem that since the fabric or the middle fabric of the stuffed bun is subjected to a lint-proof process, or since a material for preventing feathers from coming out, such as a nonwoven fabric or nylon, is used, air permeability is very poor, and the stuffed bun is easily stuffy and heavy.

In recent years, in order to solve this problem, various methods have been used such as reducing the amount of feathers, making the fabric to be processed for preventing feathers self-body ultra lightweight, or performing quilting processing by bonding processing instead of sewing to reduce the seams and improve the heat retention, and thus, feather products having light weight, no volume expansion, and high heat retention and moisture retention have been developed, but it is still difficult to completely prevent feathers from emerging, and various processes cause high costs and result in high prices of products.

Accordingly, the present inventors have made extensive studies and as a result, have provided a laminated fabric for clothing and a method for producing the laminated fabric for clothing, which can solve the above-mentioned problems of various feather products, have the heat retention properties of feathers, are light in weight, but do not swell in volume, are excellent in air permeability and heat retention properties, do not allow feathers to come out, are uniform, do not deviate, are smooth and flexible, and can be used as a fabric for clothing and the like.

According to the present invention, the following effects can be exhibited.

<1> the laminated fabric for clothes according to the present invention is a laminated fabric for clothes comprising a surface layer fabric, a feather fiber layer and a back layer fabric laminated together, wherein a spider web-like resin layer is laminated on the upper surface of the feather fiber layer (3), the surface layer fabric (2) and the feather fiber layer (3) are bonded to each other through a thermoplastic resin material, an elastic resin layer is laminated on the lower surface of the feather fiber layer (3) and a high-density resin layer is laminated thereunder, and the back layer fabric (4) and the feather fiber layer (3) are bonded to each other through the elastic resin layer and the high-density resin layer with an adhesive interposed therebetween, whereby the feather fiber layer (3) is bonded to and integrated with the surface layer fabric (2) and the back layer fabric (4) so that feathers are fixed to the surface layer fabric and the back layer fabric through the respective resins, and feathers do not come out of seams during sewing, and do not shift, the feather fiber layer is light in weight, can play the warm keeping and warming functions of the feathers, does not need a feather bag or feather prevention processing, and is good in air permeability and comfort.

In particular, since the spider web-like resin layer is laminated between the surface layer fabric and the feather fiber layer, the feathers do not protrude from the surface layer fabric, the feather fiber layer is firm and compact, and does not float due to unevenness of the feathers or swell due to air, and the like, and the hand feeling after bonding is not impaired, and a smooth, soft and beautiful fabric can be produced.

Further, if the thermoplastic resin material can be finely and uniformly dispersed by mixing with an organic solvent, for example, the thermoplastic resin material forms a smooth surface material without resin deviation even if it enters into the gaps of the spider web-like resin.

Therefore, the ground fabric and the feather fiber layer are bonded to each other through the elastic resin layer and the high-density resin layer, so that not only is scattering of the feathers prevented during production, but also the soft and tough fabric after molding exerts a high wind-proof effect.

In addition, the laminated fabric for clothing according to the present invention is obtained by laminating an elastic resin layer on the lower surface of a feather fiber layer, and further laminating a feather fiber layer on the lower surface of the elastic resin layer, and laminating the elastic resin layer on the lower surface of the feather fiber layer, or repeating the steps several times, thereby forming 2 or 3 feather fiber layers, and forming a fabric having higher heat retention properties according to the use of the clothing.

Therefore, the raw material of the top sheet or the back sheet is not limited, and therefore, the raw material can be selected according to the use application of the clothes, and for example, if the raw material having elasticity is used, the clothes bedding which is easy to manufacture such as cutting, processing and sewing, easy to wear, light in weight, free from volume expansion and warm can be provided.

Detailed Description

Embodiments for carrying out the laminated fabric for clothing and the method for producing the laminated fabric for clothing according to the present invention will be described based on the drawings of the embodiments.

Fig. 1 is a sectional view for explaining the structure of an example of the laminated fabric for clothing according to the present invention.

(a) In the description, the drawings show the state of stacking various materials, and (b) shows a laminated fabric for clothing formed by heating and pressing.

In the figure, 1 is a laminated fabric for clothes, 2 is a surface layer fabric, 3 is a feather fiber layer, and 4 is a bottom layer fabric.

Further, 5 is a spider web-like resin layer, 6 is a thermoplastic resin layer, 7 is an organic solvent, 8 is an elastic resin layer, 9 is a high-density resin layer, and 10 is an adhesive.

In the embodiment of the laminated fabric for clothing shown in fig. 1, the laminated fabric for clothing 1 is formed by laminating a surface fabric 2, a feather fiber layer 3, and a back fabric 4.

A spider web-like resin layer 5 is laminated on the upper surface of the feather fiber layer 3, and the surface layer fabric 2 and the feather fiber layer 3 are bonded via a thermoplastic resin layer 6. The thermoplastic resin layer 6 is dispersed with an organic solvent 7 in order to make the thermoplastic resin material uniform. In this example, a powdery thermoplastic resin material is mixed with an organic solvent 7, and after coating, the thermoplastic resin layer 6 is formed by further coating the organic solvent and a dispersant and stretching the thermoplastic resin material.

Accordingly, the thermoplastic resin material constituting the thermoplastic resin layer 6 is also inserted into the gaps between the spider web-like resin layers 5 laminated on the upper surfaces of the feather fiber layers 3, and is uniformly diffused between the feather fiber layers 3 and the surface fabric 2, and is bonded flexibly and smoothly.

Further, an elastic resin layer 8 is laminated on the lower surface of the feather fiber layer 3, and a high-density resin layer 9 is laminated thereunder, and the ground fabric 4 and the feather fiber layer 3 are bonded by an adhesive 10 therebetween. The material of the adhesive 10 is not particularly limited as long as it can fuse and bond the high-density resin layer 9 to the underlying fabric 4, and a general organic adhesive can be used.

The elastic resin layer 8 and the high-density resin layer 9 laminated between the feather fiber layer 3 and the ground fabric 4 are configured to have adhesive properties, and by bonding to the feathers, the feathers can be prevented from coming out or flying apart, and the laminated fabric 1 for clothing can be made smooth and have strong elasticity.

Accordingly, the feather fiber layer 3 is heated and pressed in the above-described configuration, and is bonded and integrated with the surface layer fabric 2 and the back layer fabric 4, thereby forming the laminated fabric 1 for clothing as if it were one fabric, as shown in fig. 1 (b).

In the present embodiment, the top sheet 2 and the bottom sheet 4 may be made of any material such as natural fibers such as cotton, wool, or hemp, regenerated fibers such as rayon, synthetic fibers such as polyester, nylon, or acrylic fibers, or natural or synthetic leather. The surface fabric 2 and the back fabric 4 may be made of the same material or different materials, and may be selected appropriately according to the product to be manufactured.

The raw material is not limited because the feather 30 of the feather fiber layer 3 inserted between the surface layer fabric 2 and the ground layer fabric 4, the thermoplastic resin material, the elastic resin material constituting the elastic resin layer 8, the high-density resin material constituting the high-density resin layer 9, and other resins function as adhesives to bond with the surface layer fabric 2 and the ground layer fabric 4, and a large amount of the feather 30 constituting the feather fiber layer 3 is also sandwiched between the spider web-shaped resin layer 5 laminated on the upper surface of the feather fiber layer 3 and the elastic resin layer 8 laminated on the lower surface of the feather fiber layer 3, and the respective resins enter between the feathers 30, and the feathers 30 themselves are bonded to each other by the bonding effect of the spider web-shaped resin layer 5 or the elastic resin layer 8, so that the feathers 30 do not come out of the surface layer fabric 2 or the ground layer fabric 4 alone.

Therefore, the top sheet 2 and the back sheet 4 of the laminated fabric 1 for clothing according to the present invention are not particularly limited to high-density materials, and any materials can be used regardless of the density and the presence or absence of the lint prevention processing.

In addition, in the case of manufacturing clothing or bedding, the surface layer fabric 2 of the laminated fabric for clothing 1 can be used as it is as the surface layer fabric of the product, and for example, in the case of manufacturing clothing, when a raw material having elasticity is selected for the surface layer fabric 2 or the back layer fabric 4, it is preferable that it is easy to put on and take off, and in the case of manufacturing bedding, when silk or cotton is used for the surface layer fabric 2 or the back layer fabric 4, it is soft and has a good touch to the skin, and more preferably.

As described above, the laminated fabric 1 for clothing according to the present invention is obtained by firmly bonding and integrating the surface layer fabric 2, the feather fiber layer 3, and the back layer fabric 4 with the thermoplastic resin, the spider web-like resin, and the resin of the elastic resin layer 8 having the bonding effect, and processing the bonded surfaces as if they were one fabric, so that the motions of the surface layer fabric 2, the feather fiber layer 3, and the back layer fabric 4 can follow each other without impairing the stretchability, and different materials can be arbitrarily selected for the purpose of bonding.

The feather fiber layer 3 according to the present invention is composed of an aggregate of the feathers 30. The term "feather" as used herein refers to a general term including down feather (feather) or bird feather (wing feather) of birds such as ducks and geese. Therefore, the feather fiber layer 3 may be composed of only feathers, only feather hairs, or a mixture of feathers and feather hairs.

Natural feathers are preferable for light weight, warmth retention, and soft touch, but synthetic fibers such as "artificial feathers" and "artificial feather cotton" may be used as the artificial feathers in the present invention.

In the laminated fabric 1 for clothing according to the present invention, the thermoplastic resin material used for bonding the feather fiber layer 3 and the surface fabric 2 is not particularly limited as long as the feather fiber layer 3 and the surface fabric 2 can be bonded, and therefore, the thermoplastic resin layer 6 may be selected from a vinyl acetate resin system, a polyvinyl acetal system, an ethylene vinyl acetate resin system (EVA), a vinyl chloride resin (PVC) system, an acrylic resin system (ACR), a polyamide system (PA), a polyethylene system (PE), a polyethylene terephthalate (PET) system, a polypropylene (PP) system, a Polystyrene (PS) system, a cellulose system, an α -olefin system, a synthetic rubber System (SR), and the like, in consideration of the bonding performance between the resin constituting the spider-web-like resin layer 5 and the heating process sequence of the manufacturing process, and the like, depending on the material of the surface fabric 2.

In this embodiment, polyethylene, polypropylene, or the like is preferable because it is excellent in adhesiveness and moldability and is easily fused with the surface layer fabric 2.

In the case where the surface layer fabric 2 is a thin material, for example, a thermoplastic hot-melt adhesive that can be bonded at high speed without breaking the material by heating and melting can be used.

The thermoplastic resin material may be in the form of powder, granules, fibers, or liquid, but the thermoplastic resin layer 6 may be formed by mixing the powdered thermoplastic resin material with the organic solvent 7 and coating the spider web-like resin layer 5 with the powdered thermoplastic resin material.

In order to improve the dispersibility of the organic solvent 7, the thermoplastic resin layer 6 may be formed by placing the organic solvent 7 mixed with the powdery thermoplastic resin material in a spot shape (spot shape) on the spider web-like resin layer 5, and applying a dispersant thereon to diffuse the thermoplastic resin material.

By forming the thermoplastic resin layer 6 in this way, the powdery thermoplastic resin material is uniformly dispersed in the solvent, and the feather fiber layer 3 and the surface fabric 2 can be smoothly bonded to each other through the spider web-like resin layer 5, and can be made smoother and more refined by heating and melting.

That is, the thermoplastic resin material can be placed in a spot or dot shape even when it is applied over the entire surface, and the amount of the organic solvent 7 or the dispersant to be added is preferably selected appropriately in consideration of the habit with the resin. Thus, the surface layer fabric 2 does not undergo a molding change such as shrinkage, and the entire laminated fabric 1 for clothing becomes a fabric having high strength and fluidity.

Examples of the organic solvent 7 for uniformly dispersing the thermoplastic resin material constituting the thermoplastic resin layer 6 include alcohols such as ethanol and isopropyl alcohol, ketones such as acetone, methyl ethyl ketone and cyclohexanone, and esters such as ethyl acetate and butyl acetate, and it is preferable to select a material having good dispersibility in the habit of the thermoplastic resin material.

In the present invention, the spider web-like resin layer 5 is formed of a resin formed in a spider web-like shape.

The spider web-like resin layer 5 is made of a material selected from various thermoplastic resins such as polyolefin, polyester, and polyamide, and fibers. These resin materials are sprayed out in a spider-web shape. Therefore, when the molding is performed under heat and pressure, the resin sprayed in the shape of a spider web melts and is complexly bonded to the feathers, and therefore, the feathers can be prevented from floating, shifting, popping or scattering. Further, since a plurality of pores are formed in the spider web-like resin layer 5, and the surface layer fabric 2 is hard to be bonded thereto, and for example, a thermoplastic resin mixed with the organic solvent 7 laminated on the upper layer is introduced into the pores, and the surface layer fabric 2 and the feather fiber layer 3 are easily fused at the time of heating and pressurizing, and the feathers 30 are reliably bonded thereto, the feathers 30 can be prevented from dropping off and scattering, and the feathers 30 are less likely to be raised in a convex-concave manner.

As described above, the laminated fabric 1 for clothing of the present invention is relatively characterized in that a spider web-like resin layer 5 is provided between the feather fiber layer 3 and the surface layer fabric 2. This is because, when the feather fiber layer 3 and the surface layer fabric 2 are directly bonded without providing the spider web-like resin layer 5, the feathers 30 cannot be completely prevented from coming out and falling off, scattering when processing clothing, and the like, and by providing the spider web-like resin layer 5, the above-mentioned problems can be remarkably reduced, and a smooth fabric with high warmth retention can be obtained.

The elastic resin layer 8 of the present invention is made of a resin having elasticity.

Examples of the resin having elasticity constituting the elastic resin layer 8 include polyurethane, thermoplastic polyurethane, polyethylene terephthalate, polytetrafluoroethylene, rubber, silicone resin, and a combination thereof. Thus, a material selected from these materials is spray-coated in a liquid crystal state, or a formed film or sheet is thermally melted to form the elastic resin layer 8. In particular, by depositing the feathers 30 on the liquid-crystalline elastic material, scattering of the feathers 30 in the production stage is prevented, and effects of imparting stretchability, bendability, and elasticity to the laminated fabric for clothing 1 can be expected.

Further, the elastic resin material is preferably sprayed in spots or dots instead of being coated over the entire surface, so that air permeability can be improved.

Accordingly, the high-density resin layer 9 of the present invention is a layer containing a resin material at a relatively high density, and contains a resin at a higher density than the elastic resin layer 8. By "high density" is meant herein the mass per unit volume of the layers. By interposing a high-density resin material between the feather fiber layer 3 and the ground fabric 4, the rigidity of the laminated fabric 1 for clothing can be improved, and a fabric having a tough texture can be formed.

The material of the high-density resin layer 9 is not particularly limited, but preferably includes 1 or more thermoplastic resins, and may contain resins other than thermoplastic. The high-density resin layer 9 may contain a material constituting the thermoplastic resin layer 6 and a material constituting the elastic resin layer 8, and for example, 1: 1-1: 4, the material of the thermoplastic resin layer 6 and the material of the elastic resin layer 8 are mixed in a ratio of 4. By adopting the material, the fabric has silky flexibility, can improve the windproof effect and can further improve the heat retention property.

In the present embodiment, the high-density resin layer 9 is laminated between the feather fiber layer 3 and the ground fabric 4, but depending on the application, the positions of the spider web-like resin layer 5 and the high-density resin layer 9 laminated between the feather fiber layer 3 and the surface fabric 2 may be changed. For example, it is preferable to finish the back sheet 4 side of the laminated fabric 1 for clothing smoothly and smoothly without unevenness.

The feather fiber layer 3 constituting the laminated fabric 1 for clothing according to the present invention is preferably configured such that the thickness α of the feather fiber layer 3 is about 0.05mm to 2.0mm because, if it is too thin, the amount of feathers is too small to ensure warmth retention, and if it is 2.0mm or more, the thickness of the laminated fabric 1 for clothing becomes thick, the volume expands, there is no light feeling, and it is difficult to perform manufacturing operations such as cutting or sewing.

Therefore, it is more preferable that the amount of feathers is adjusted so that the thickness α of the feather fiber layer 3 is about 0.4 to 0.8mm, although it depends on the raw materials of the top fabric 2 and the bottom fabric 4, because the feathers are light in weight and do not expand in volume, and the feathers are processed more like one fabric, and the production work such as cutting and sewing can be performed as in a normal one fabric, and therefore, it is preferable.

The thickness α is the thickness of the feather fiber layer 3 in the final form, and is the thickness of the portion from which the surface layer fabric 2 and the back layer fabric 4 are removed, that is, the surface layer fabric 2 and the feather fiber layer 3 are bonded to each other through the spider web-like resin layer 5 by the thermoplastic resin layer 6, the back layer fabric 4 and the feather fiber layer 3 are bonded to each other with the elastic resin layer 8 and the high-density resin layer 9 interposed therebetween, and the thickness of the portion from which the surface layer fabric 2 and the back layer fabric 4 are removed in a state in which the laminate is heated to melt the respective resin materials and pressurized, by forming the feather fiber layer 3 in an extremely thin state, the laminated fabric 1 for clothes can be finished into as if one fabric.

In the cross-sectional view for explaining the structure of another embodiment of the laminated fabric for clothing according to the present invention in fig. 2, the feather fiber layer 3 is 2 layers in addition to the structure of the above embodiment.

In the figure, (a) shows a state of various materials to be laminated and (b) shows a laminated fabric for clothes formed by heating and pressing.

In the structure of the above example, the elastic resin layer 8 is laminated on the lower surface of the feather fiber layer 3, and in the case of forming the feather fiber layer 3 to be 2 weight as in the present example, the feathers 30 are further laminated under the elastic resin layer 8 to form the feather fiber layer 3 ', and the elastic resin layer 8' is laminated on the lower surface thereof.

Thus, the feathers 30 of the upper feather fiber layer 3 and the feather fiber layer 3' of the 2 nd layer are not mixed, and the feathers can exhibit the effect as the feather fiber layer 3, and the scattering of the feathers 30 and the emergence of the feathers 30 in the manufacturing process can be prevented.

In the above-described embodiment, the feather fiber layer 3 is 2 layers, but similarly, the elastic resin layer 8 is laminated on the lower surface of the feather fiber layer 3, and the feather fiber layer 3 and the elastic resin layer 8 are repeatedly placed in this order on the lower surface, whereby the feather fiber layer 3 can be formed into a plurality of layers to further improve the heat retention property.

In this way, in the laminated fabric 1 for clothing according to the present invention, the surface layer fabric 2, the feather fiber layer 3, and the bottom layer fabric 4 are laminated in this order from above, the feather fiber layer 3 and the surface layer fabric 2 are bonded via the spider web-like resin layer 5, and the feather fiber layer 3 and the bottom layer fabric 4 are bonded via the elastic resin layer 8 and the high-density resin layer 9, and are integrally formed.

Accordingly, the feather fiber layer 3 is configured to sandwich a large amount of feathers and is configured to be thinner than the thicknesses of the upper and lower surface sheets 2 and the bottom sheet 4. For example, when the thickness of the whole laminated fabric 1 for clothing is approximately 2.5cm, the feather fiber layer 3 is approximately 0.5 to 0.8 mm.

Therefore, the laminated fabric 1 for clothing according to the present invention can be processed as if it is one fabric as described above, and can be used as a fabric for any clothing such as jackets, trousers, skirts, shirts, underwear and hats for cold protection, and the surface fabric 2 of the laminated fabric 1 for clothing can be directly used as a surface fabric for various products.

The laminated fabric 1 for clothing according to the present invention can be used for a part of various kinds of clothing. For example, a product with high design can be obtained by using the laminated fabric for clothing 1 only at the substantial front and substantial back of the jacket and combining the existing light and thin fabrics for the sleeve part.

Similarly, the laminated fabric for clothing 1 according to the present invention is also applicable to bedding. The surface layer fabric 2 of the laminated fabric 1 for clothing can be used as it is as a surface layer fabric for various products for bedding.

Therefore, the bedding may be configured such that the whole product is constituted by the laminated fabric for clothing 1, and the laminated fabric for clothing 1 of the present invention is used for a part of the product.

When the laminated fabric 1 for clothing is used in any of clothing and bedding, if at least the raw material of the surface layer fabric 2 is selected in accordance with the product to be manufactured to constitute the laminated fabric for clothing 1, the clothing and bedding manufactured from the suitable raw material can be manufactured while keeping warm with light weight.

Accordingly, the laminated fabric 1 for clothing according to the present invention includes the spider web-like resin layer 5 on the surface fabric 2 side, and the elastic resin layer 8 and the high-density resin layer 9 on the back fabric 4 side, and therefore, compared to the case where the surface fabric 2, the feather fiber layer 3, and the back fabric 4 are bonded only with a hot melt adhesive or the like, the laminated fabric 1 for clothing has a smooth and flexible surface without fine irregularities, and is a flexible fabric having strength and rigidity, and is excellent in heat retention and wind resistance.

Accordingly, the feathers 30 are firmly adhered to each other and the surface layer fabric 2 and the back layer fabric 4 by the respective resin materials, and the feathers 30 are sandwiched by the spider web-like resin layer 5 or the elastic film layer 8, so that the feathers 30 do not protrude or pass through, and the excellent laminated fabric 1 for clothes which does not scatter the feathers 30 is produced in the production process.

Next, a method for producing a fiber laminate according to the present invention will be described with reference to fig. 3. As an example of the method for producing the fiber laminate 1 according to the present invention, the following steps are performed: (1) the method for manufacturing the layered body comprises the steps of (1) placing a base fabric on a base, wherein the side where feathers are layered is an upper surface, (2) coating an adhesive on the base fabric, (3) coating a high-density resin material and an elastic resin material on the adhesive, (4) layering feathers on the base fabric on which the high-density resin material and the elastic resin material are coated, (5) spraying a resin in a spider-web shape on the basis of the layered feathers to provide a spider-web-shaped resin layer, (6) coating a thermoplastic resin dispersed in an organic solvent on the spider-web-shaped resin layer, (7) then placing a surface fabric on the base fabric to manufacture a layered body, wherein the side where feathers are layered is a lower surface, and (8) heating, pressurizing, drying, and bonding the layered body to be integrated.

In fig. 3, a base fabric 4 is provided so that the side on which feathers are layered is the upper surface (step 1), and an adhesive is applied (step 2).

The adhesive applied to the ground fabric 4 is easily fused with the ground fabric 4 and the high-density resin layer 9 laminated thereon, and can be smoothly bonded, even if not having a particularly strong adhesive force. In the present embodiment, the liquid organic adhesive is thinly applied, but an adhesive conforming to the resin material habit of the high-density resin layer 9 is preferable.

Accordingly, in the 2 nd step, the high-density resin material constituting the high-density resin layer 9 is laminated by spray coating on the upper surface of the adhesive-coated layer by the resin supply unit, and the resin having elasticity constituting the elastic resin layer 8 is laminated on the upper surface thereof (the 3 rd step).

In this example, the material constituting the high-density resin layer 9 was set to 1: 1-1: 4, a thermoplastic resin material and the above elastic resin material are mixed at a ratio of 4, and a material having a high density is used.

In the present example, the material of the elastic resin layer 8 was formed by spraying liquefied polyurethane in a spot state to improve air permeability. Further, the elastic resin material has a lower density than the high-density resin material constituting the high-density resin layer 9.

That is, the resin material of the high-density resin layer 9 has a higher density than the resin material of the elastic resin layer 8, and therefore can be used as the resin constituting the high-density resin layer 9. By laminating resin layers having different densities in this manner, the laminated fabric 1 for clothing can be formed which is smooth and tough while maintaining air permeability and improving warmth retention.

Thereafter, feathers 30 are stacked on the upper surface of the elastic resin layer 8 by a feather supply unit (step 4).

The feather supply unit selects a method that allows the feathers to be laminated as spotless as possible. For example, the feather may be adsorbed by a method of naturally dropping the feather on the elastic resin coated thereon or by a method similar to electrostatic flocking by arranging an electrode. It is preferable to use the elastic resin in a highly adhesive state because the feather 30 that has naturally fallen can be reliably received.

In the 4 th step, after the feather fiber layer 3 is formed by stacking the feathers 30, a resin material constituting the spider-web-like resin layer 5 is sprayed on the upper surface of the feather fiber layer 3 (the 5 th step). Further, although a spider-web-shaped resin sheet or a resin band may be disposed on the feather fiber layer 3 in advance, the spider-web-shaped resin layer 5 is preferably formed by spraying a spider-web-shaped resin so as to flexibly correspond to the shape of the fabric.

By providing the spider web-like resin layer 5 in this way, the feathers 30 can be significantly prevented from coming out of the surface fabric 2.

Accordingly, a thermoplastic resin material dispersed with the organic solvent 7 is applied to the upper surface of the spider web-like resin layer 5 to form a thermoplastic resin layer 6 (step 6). Since the thermoplastic resin layer 6 is the upper surface of the spider-web-shaped resin layer 5, the thermoplastic resin material preferably reliably enters the air holes of the spider-web-shaped resin layer 5, and a method of uniformly dispersing the powdery thermoplastic resin material with the organic solvent 7 may be mentioned, but a method of using a liquid thermoplastic resin material not containing the organic solvent 7 may also be used. Further, the material obtained by mixing the thermoplastic resin material with the organic solvent 7 may be arranged in a spot shape and uniformly stretched using the organic solvent and the dispersant.

Then, the surface layer fabric 2 having the surface on which the feathers are laminated as the lower surface is combined with the back layer fabric 4 so as to sandwich the various resins and feathers 30 laminated on the back layer fabric 4 (7 th step, 8 th step (a)).

In the present embodiment, the thermoplastic resin layer 6 is laminated on the upper surface of the spider-web-shaped resin layer 5, but a thermoplastic resin material may be coated in a spot shape on the back surface of the surface layer fabric 2 and laminated on the upper surface of the spider-web-shaped resin layer 5 so as to be positioned in the bottom layer fabric 4.

Further, depending on the kind of the resin material constituting the spider web-like resin layer 5, the thermoplastic resin material laminated on the upper surface thereof may be heated and melted before being laminated, or the process may be appropriately added or changed depending on the kind and characteristics of the resin material.

Accordingly, the laminated body completed in the 8 th step (a) is pressurized by the heating and compressing unit (8 th step (b)), and then is dried and finished by the drying unit (8 th step (c)).

The pressurization of the compression unit is adjusted so that the feather fiber layer 3 has a predetermined thickness α.

Although not shown, the laminated fabric for clothing 1 can be wound in a roll shape and finished by performing the above-described series of manufacturing steps on a manufacturing line.

Further, the operation of the press machine and the dryer may not be separated, and if the compression (close contact) heating and the drying can be simultaneously performed at once by a hot press machine or the like, the operation efficiency can be improved.

The production of the laminated fabric 1 for clothing of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

In the laminated fabric for clothing according to the present invention, the surface layer fabric, the feather fiber layer, and the back layer fabric are laminated in this order, and the feather fiber layer is formed by bonding and integrating the surface layer fabric and the back layer fabric with various resin materials interposed therebetween, so that the conventional feather products such as a down quilt and a down jacket are not necessarily described, and can be widely used for cloth products requiring heat retention such as shirts, trousers, skirts, underwear, hats, handbags, uppers of boots, bags, quilts, terry cloths, coverlets, and furnace covers.
