Technical Field

the present invention relates to an adhesive interlining to be adhered to the back surface of a clothing fabric among fabrics of clothing.

Background

The adhesive interlining is used to improve the formability and shape retention of the three-dimensional shape of a fabric constituting a garment, or to partially reinforce the fabric. The adhesive interlining is adhered to the back of a cloth of a garment at the time of use.

One of the methods of applying the adhesive for adhering the backing cloth is a method called dot type (dot type). This type of adhesive interlining includes: a base fabric disposed on the back side of the cloth; and a plurality of adhesive portions formed in a dot shape. The plurality of adhesive portions are arranged on the front surface of the base fabric arranged to face the back surface of the clothing fabric. The adhesive portion is formed by applying an adhesive to the base fabric.

Here, 2 directions orthogonal to each other along the surface of the base fabric are referred to as a 1 st direction and a 2 nd direction.

For example, in a state where the surface of the base fabric of the front body interlining of a man's garment is oriented in the vertical direction, the warp direction as the direction of gravity is the 1 st direction, and the weft direction, which is a direction orthogonal to the warp direction, is the 2 nd direction. Various interlining fabrics including an adhesive interlining fabric are required to have high bending rigidity (called tension) in the weft direction and good shape retention in that direction. Since the weft direction is less likely to be subjected to gravity than the warp direction, wrinkles are likely to occur in the weft direction.

Then, many attempts have been made to improve the bending rigidity in the weft direction by examining the arrangement of the adhesive portions.

For example, in the "regular arrangement" described in japanese unexamined patent publication No. 59-88417, as shown in fig. 9A, in the adhesive interlining 30, a plurality of adhesive portions 32 are arranged at regular intervals in both the weft direction and the warp direction.

In the regular arrangement, the number of the adhesive portions 32 positioned on the same line extending in the weft direction is increased, and the bending rigidity in the weft direction can be improved, but on the other hand, the extension in the weft direction is excessively restricted because of the presence of the plurality of adhesive portions 32. This reduces the widthwise elongation of the base fabric 31, and the bonded garment has a hard texture (feel when touched). In addition, when the cover fabric tries to stretch in the weft direction, the base fabric 31 cannot stretch in the weft direction following the cover fabric, and there is a possibility that the adhesive portion 32 peels off from the cover fabric.

In addition, the phenomenon that the cloth material stretches in the weft direction may occur not only when a tensile load is applied to the weft direction. For example, when a cloth made of a material such as wool which easily absorbs moisture (water) is subjected to a humidification process such as Tunnel fish (Tunnel fish) during washing, the humidification process may occur. This phenomenon is called so-called wet expansion (hygral expansion), and is a phenomenon in which a garment material stretches.

In recent years, an arrangement method called "random arrangement" has become the mainstream, instead of the "regular arrangement" (see, for example, japanese patent laid-open No. 2002-371414). As shown in fig. 9B, in the "random arrangement", the adhesive portions 32 are formed on the base cloth 31 in a random arrangement state without regularity.

Disclosure of Invention

problems to be solved by the invention

As described above, in the adhesive interlining 30, the adhesive sections 32 are arranged in a random arrangement, and the number of the adhesive sections 32 located on the same line extending in the weft direction is smaller than that in the case of arranging in a regular arrangement, and the restriction of the adhesive sections on the extension in the weft direction of the base cloth 31 is reduced. The reduction in the widthwise elongation of the base fabric can be suppressed.

however, in the random arrangement, there is a problem that bending rigidity becomes high (tension occurs) not only in the weft direction but also in an equi-directional ground, for example, in a direction in which both the warp direction and the weft direction and the warp direction are inclined.

An object of the present invention is to provide an adhesive interlining capable of suppressing a reduction in the elongation in the 2 nd direction orthogonal to the 1 st direction due to an adhesive portion, improving the bending rigidity in the 2 nd direction, and suppressing the bending rigidity in a direction different from the 2 nd direction.

Means for solving the problems

An adhesive interlining cloth for solving the above problems includes: a base fabric having a surface arranged to face a back surface of the clothing fabric; and a plurality of spot-like adhesive portions arranged on the surface of the base cloth, wherein the adhesive interlining is adhered to the back surface of the clothing fabric via the plurality of adhesive portions. 2 directions orthogonal to each other along the surface of the base fabric are a 1 st direction and a 2 nd direction, and a plurality of lines extending in the 2 nd direction while being spaced apart from each other in the 1 st direction are reference lines. A waveform extending in the 2 nd direction while being displaced in the 1 st direction with respect to each of the reference lines is an arrangement guide with respect to the plurality of bonding portions of the base fabric. In each of the waveforms, a portion where one displacement amount in the 1 st direction with respect to the reference line increases from zero, decreases, and becomes zero again is a 1 st unit waveform, and a portion where the other displacement amount in the 1 st direction with respect to the reference line increases from zero, decreases, and becomes zero again is a 2 nd unit waveform. The plurality of bonding portions are arranged along the 1 st unit wave and the 2 nd unit wave alternately arranged in the 2 nd direction in a connected state or a separated state.

Detailed Description

An embodiment of the adhesive interlining is described below with reference to fig. 1 to 5.

Fig. 1 schematically shows a part of a cloth 10 of a garment in order to define a direction in the cloth 10. As shown in fig. 1, 2A and 2B, the surface layer portion of the fabric 10 is constituted by a cover fabric 11. The adhesive interlining 12 includes: a base fabric 13 disposed on the back side of the clothing fabric 11; and a plurality of adhesive portions 16 formed on the front surface (the surface facing the back surface of the clothing fabric 10) of the base fabric 13.

As the base fabric 13, woven fabric, nonwoven fabric, or knitted fabric can be used. In the present embodiment, a woven fabric is used as the base fabric 13. In the present embodiment, as shown in fig. 3B, a plain cloth woven so that warp yarns 14 and weft yarns 15 alternately cross each other is used as a woven cloth. The woven fabric may be a fabric woven by a weaving method other than plain weaving, for example, twill weaving, satin weaving, or the like. The base fabric 13 is configured to have a gap between adjacent warp yarns 14 and a gap between adjacent weft yarns 15.

As the warp yarns 14 and the weft yarns 15, for example, synthetic fibers such as polyester fibers, polyamide fibers, polyolefin fibers, acrylic fibers, and polyurethane fibers are used. Instead of the synthetic fibers, semi-synthetic fibers such as acetate fibers, regenerated fibers such as viscose fibers, or natural fibers such as cotton, wool, silk, or hemp may be used as the warp yarns 14 and the weft yarns 15. The above-mentioned various fibers may be used alone or in combination. As the warp yarns 14 and the weft yarns 15, any of textile yarns and filament yarns can be used.

2 directions orthogonal to each other along the surface of the base cloth 13 are set as a 1 st direction and a 2 nd direction. In the present embodiment, as shown in fig. 1 and 3B, in a state where the surface of the base fabric 13 is vertical, the warp direction, which is the direction of gravity, is the 1 st direction, and the weft direction, which is the direction orthogonal to the warp direction, is the 2 nd direction. The adhesive interlining 12 is arranged such that the warp yarns 14 extend in the warp direction and the weft yarns 15 extend in the weft direction in use.

As shown in fig. 3A and 3B, the adhesive portion 16 is formed in a dot shape (dot shape) and arranged at a plurality of positions on the surface of the base cloth 13. The adhesive portion 16 is formed by applying an adhesive to the base fabric 13. The shape of the adhesive portion 16 viewed from the front (direction orthogonal to the surface of the base fabric 13) is not particularly limited. The adhesive portion 16 is typically circular in plan view, but may be elongated such as an oval shape or an oblong shape.

As shown in fig. 2A and 2B, as the adhesive, a material that can be applied to the base fabric 13 and is melted by heating and adhered to the clothing fabric 11 is used. In the present embodiment, a thermoplastic resin is used as a material satisfying the above conditions. As the thermoplastic resin, any of thermoplastic resins conventionally used for bonding a backing cloth, for example, polyester-based resins, polyamide-based resins, polyethylene-based resins, ethylene-vinyl alcohol-based resins, polyvinyl alcohol-based resins, and the like can be used.

The mode of applying the adhesive made of the thermoplastic resin to the base fabric 13 may be any of the disclosed Single-point mode (Single dot form) made of a Single-component thermoplastic resin, or the Double-point mode (Double dot form) made of a three-dimensional two-layer structure formed by laminating 2 different thermoplastic resins (see japanese unexamined patent publication No. 56-55206).

For applying the adhesive to the base fabric 13, the following method is used, for example. This method is a method conventionally employed.

The method comprises the following steps: filling a thermoplastic resin into a hollow cylindrical roller having a plurality of through holes in the circumferential surface thereof; extruding the molten thermoplastic resin from the through-holes while rolling the roller on the base fabric 13; the thermoplastic resin extruded from the through-holes is attached to the base cloth 13 contacted by the rollers.

In the adhesive interlining 12 shown in fig. 3A and 4, a plurality of weft threads 17 extending in the weft direction and parallel to each other are reference threads. Adjacent weft yarns 17 are separated from each other in the warp direction. A sine wave traveling in the weft direction while periodically shifting in the warp direction with respect to the weft 17 is a waveform WF. The adhesive portion 16 is arranged along the wavy WF with respect to the base fabric 13. That is, the waveform WF serves as an arrangement guide of the adhesive portion 16. The minimum value of the amplitude a of the waveform WF as a sine wave is preferably set to a value that spans 2 or more weft yarns 15.

In each waveform WF, a portion where the displacement amount (separation distance) of the 1 st side (upper side in fig. 4) in the warp direction with respect to the weft 17 increases from zero and then decreases to become zero again is referred to as a 1 st unit waveform UW 1. A portion which is continuous with the 1 st unit waveform UW1 and in which the displacement amount (separation distance) toward the 2 nd side (lower side in fig. 4) in the warp direction with respect to the weft 17 increases from zero, decreases, and becomes zero again is referred to as a 2 nd unit waveform UW 2. That is, each waveform WF has: the 1 st unit wave UW1 located on the 1 st side in the warp direction with respect to the weft 17; and the 2 nd unit wave UW2 located on the 2 nd side in the warp direction with respect to the weft 17. These 1 st and 2 nd unit waveforms UW1 and UW2 constitute 1 unit waveform UW. The 1 st unit waveform UW1 and the 2 nd unit waveform UW2 are alternately arranged in the weft direction while being continuous with each other in the weft direction, thereby constituting a waveform WF. Here, since the waveform WF, which is set as the alignment guide of the adhesive portion 16, is a sine wave, the displacement amount (separation distance) of each of the 1 st unit waveform UW1 and the 2 nd unit waveform UW2 with respect to the weft 17 increases from zero to a maximum value, and then decreases to zero again.

In the present embodiment, 1 group is constituted by 2 waveforms WF arranged in a state of being close to each other in the radial direction (see fig. 3A). The groups are arranged at regular intervals in the warp direction. The interval between adjacent groups is set to be larger than the interval between 2 waveforms WF in the same group. However, the arrangement of the waveforms WF is not essential, and a plurality of waveforms WF may be arranged at equal intervals in the warp direction without forming a group.

The plurality of adhesive sections 16 are arranged on the base fabric 13 for each wave WF along the 1 st unit wave UW1 and the 2 nd unit wave UW2 that continue in the weft direction. In the present embodiment, the plurality of adhesive sections 16 arranged in a row are disposed at positions separated from each other on the 1 st unit waveform UW1 and the 2 nd unit waveform UW 2.

As shown in fig. 4 and 5, in the 1 st unit wave UW1 and the 2 nd unit wave UW2, when an angle formed by a line L1 connecting adjacent bonding portions 16 to each other with respect to a line L2 extending in the weft direction and passing through the weft yarn 15 is θ, the angle θ is set to a value greater than 10 ° and less than 45 °. The distance D1 between the adjacent adhesive sections 16 is set to 0.2mm in the present embodiment, but the present invention is not limited thereto.

The adhesive interlining 12 configured as described above is bonded to the back surface of the clothing fabric 11 via the adhesive portion 16 as shown in fig. 2B. The adhesive interlining 12 and the clothing fabric 11 constitute a fabric 10 of the clothing.

Next, the operation and effect of the adhesive interlining 12 of the present embodiment will be described.

Here, the following is assumed: the regular array and the random array are compared with each other, and the number of the adhesive portions 16 arranged per unit area of the base fabric 13 is the same as or smaller than the compared object. On this premise, as shown in fig. 3A, 3B, and 4, the waveform WF as the guide of the arrangement of the adhesive portions 16 is formed of a sine wave having an amplitude a and a wavelength λ. The 1 st unit waveform UW1 and the 2 nd unit waveform UW2 constituting the sine wave are alternately arranged in the weft direction. The 1 st unit waveform UW1 and the 2 nd unit waveform UW2 each increase in displacement amount in the warp direction with respect to the weft 17 from zero to a maximum value, and then decrease to zero again. Therefore, the plurality of adhesive portions 16 are arranged on the 1 st unit waveform UW1 and the 2 nd unit waveform UW 2. In the present embodiment, the number of the adhesive portions 16 located on the same line (1 weft yarn 15) extending in the weft direction is reduced as compared with the case of arranging in the regular arrangement.

In the present embodiment, the number of the adhesive portions 16 positioned on the same line extending in the weft direction is smaller than in the case of the regular arrangement, but a certain number of the adhesive portions 16 are positioned on the same line (the weft yarn 15). Therefore, sufficient bending rigidity can be obtained in the weft direction. When the warp rigidity of the base fabric 13 in the weft direction is increased, the shape retention property in the weft direction is improved. Therefore, gravity is less likely to act in the weft direction than in the warp direction, and wrinkles are less likely to occur in the weft direction.

In the present embodiment, the number of the adhesive portions 16 located on the same line (1 weft yarn 15) is smaller than that in the case where the adhesive portions 16 are arranged in a regular arrangement as described above, and the restriction of the extension of the base fabric 13 in the weft direction by the adhesive portions 16 is reduced. As a result, the fabric 10 of the garment can be prevented from having a hard feel by suppressing the decrease in the elongation of the base fabric 13 in the weft direction.

when a tensile load is applied to the fabric 10 or the cloth 11 made of a material such as wool which readily absorbs moisture (water) is subjected to a humidification treatment such as tunnel fish during washing so that the cloth 11 is stretched in the weft direction, the base fabric 13 can be stretched in the same direction following the cloth 11. As a result, the adhesive portion 16 can be prevented from peeling off from the clothing fabric 11.

The 1 st unit waveform UW1 and the 2 nd unit waveform UW2 extend in the weft direction while being displaced in the warp direction by the amplitude a. Therefore, the number of the adhesive portions 16 arranged in a direction different from the weft direction, for example, the number of the adhesive portions 16 arranged in the warp direction and the number of the adhesive portions 16 arranged in directions inclined with respect to both the weft direction and the warp direction are reduced in the base fabric 13, as compared with the case where the adhesive portions are arranged in a random arrangement. The bending rigidity in the direction different from the weft direction becomes lower than that in the case where the adhesive portions are arranged in a random arrangement.

In particular, in the present embodiment, as shown in fig. 4 and 5, since the angle θ is larger than 10 °, it is less likely that the adjacent 2 bonded portions 16 are all located on the same line (1 weft yarn 15). Therefore, the number of the adhesive portions 16 located on the same line (1 weft yarn 15) can be reduced. Therefore, sufficient bending rigidity can be obtained in the weft direction, and the decrease in the extensibility of the base fabric 13 in the weft direction due to the adhesive portion 16 can be suppressed.

Since the angle θ is smaller than 45 °, the degree of influence of the adhesive part 16 on the bending rigidity in the warp direction is smaller than the degree of influence on the bending rigidity in the weft direction. Therefore, unlike the random arrangement in which the bending rigidity increases in any direction (equi-directionally), the bending rigidity in the warp direction can be made smaller than the bending rigidity in the weft direction. In other words, the bending rigidity can be increased only in the weft direction, which is a direction in which high bending rigidity is required, and the bending rigidity in the other directions can be reduced.
