Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1 to 8, a breathable light down jacket fabric according to an embodiment of the present invention includes an upper fabric 1, a lower fabric 2, and a connecting line 3; the upper fabric 1 includes a plurality of first warp yarns 11 and a plurality of first weft yarns 12 interwoven with the plurality of first warp yarns 11, and the plurality of first weft yarns 12 are interwoven with the plurality of first warp yarns 11 to form a plurality of first ventilation perforations 13.

The lower fabric 2 includes a plurality of second warp yarns 21 and a plurality of second weft yarns 22 interwoven with the plurality of second warp yarns 21, and the plurality of second weft yarns 22 and the plurality of second warp yarns 21 are interwoven to form a plurality of second ventilation perforations 23.

When the fabric is manufactured, the first weft yarns 12 and the first warp yarns 11 are interwoven to form a plurality of first breathable through holes 13, the second weft yarns 22 and the second warp yarns 21 are interwoven to form a plurality of second breathable through holes 23, then the connecting lines 3 penetrate through the first breathable through holes 13 and the second breathable through holes 23, so that the upper fabric 1 and the lower fabric 2 are connected together, the two adjacent connecting lines 3, the upper fabric 1 and the lower fabric 2 form a containing cavity 4 together, and the containing cavity 4 can contain down. Because the connecting line 3 passes through the first ventilation through hole 13 and the second ventilation through hole 23, after the upper fabric 1 and the lower fabric 2 are manufactured, sewing is not needed to be carried out through sewing threads, and therefore, the situation that down feather comes out from the sewing is avoided. The first and second ventilation holes 13 and 23 have small apertures, so that the down feather does not come out of the first and second ventilation holes 13 and 23. The first and second ventilation through holes 13 and 23 reduce the overall weight, so that the overall weight is light, and at the same time, the first and second ventilation through holes 13 and 23 facilitate ventilation. Therefore, the invention has good air permeability, good down-proof effect and light weight.

As shown in fig. 5, as an example, the first warp yarn 11 includes a core 5, a winding line segment 51 and an outer covering 52, the winding line segment 51 is provided in plural, each winding line segment 51 is wound on the core 5, a groove 53 is formed between the end portions of two adjacent winding line segments 51 adjacent to each other and the core 5, the outer covering 52 is wound on the winding line segment 51 and the groove 53, the outer covering 52 is wound on the winding line segment 51 to form a gentle section 521, and the outer covering 52 is wound on the groove 53 to form a concave section 522; after the first warps 11 are interwoven with the first wefts 12, the outer sides of two adjacent first wefts 12 and the concave sections 522 of two adjacent first wefts 11 form the first ventilation perforations 13.

A plurality of winding wire segments 51 may be wound on the core wire 5 using a winding apparatus such that a groove 53 is formed between the end portions of two adjacent winding wire segments 51 that are close to each other and the core wire 5, and then the outer covering wire 52 may be wound on the winding wire segments 51 and the groove 53 using the winding apparatus. Wherein, the winding device is the prior art and is not described herein.

That is to say, in the upper fabric 1, the special first warp yarn 11 and the common first weft yarn 12 are interwoven to form the upper fabric 1 having the first ventilation through holes 13, the first ventilation through holes 13 of the upper fabric 1 are substantially strip-shaped and can be used for the connecting wire 3 to pass through, after the connecting wire 3 passes through the strip-shaped first ventilation through holes 13, the friction force between the connecting wire 3 and the first ventilation through holes 13 is relatively large, so that the connecting wire 3 is not easy to displace, thereby improving the fabric strength, and the cross section of the connecting wire 3 can be rectangular so as to facilitate the first ventilation through holes 13 to pass through.

As shown in fig. 6, as another example, each of the first warp yarn 11 and the first weft yarn 12 includes a core 5, a plurality of winding segments 51, and an outer covering 52, each winding segment 51 is wound around the core 5, a groove 53 is formed between the end portions of two adjacent winding segments 51 adjacent to each other and the core 5, the outer covering 52 is wound around the winding segments 51 and the groove 53, the outer covering 52 is wound around the winding segments 51 to form a gentle portion 521, and the outer covering 52 is wound around the groove 53 to form a concave portion 522; after the first warps 11 are interwoven with the first wefts 12, the concave sections of two adjacent first wefts 12 and the concave sections of two adjacent first wefts 11 form the first air-permeable through holes 13.

That is, in the upper layer fabric 1, the special first warp yarn 11 is interwoven with the special first warp yarn 11 to form the upper layer fabric 1 having the first through-holes 13, and the first through-holes 13 of the upper layer fabric 1 are substantially square and can be penetrated by the connecting line 3. The square first ventilation through hole 13 has a larger aperture, so that the connecting wire 3 can pass through the square first ventilation through hole conveniently, and the cross section of the connecting wire 3 can be circular. The first through-air-penetration perforation 13 is formed by four concave sections 522 of the two first weft yarns 12 and the concave sections 522 of the two first warp yarns 11, so that the aperture of the first through-air-penetration perforation 13 is larger, and the connecting line 3 can pass through the perforation. It is noted that the first gas-permeable perforations 13 in this example are small relative to the down feather, which does not come out of the first gas-permeable perforations 13.

As shown in fig. 7, as still another example, the second warp 21 includes a core 5, a plurality of winding segments 51, and an outer covering 52, each winding segment 51 is wound on the core 5, a groove 53 is formed between the end of each adjacent winding segment 51 and the core 5, the outer covering 52 is wound on the winding segments 51 and the groove 53, the outer covering 52 is wound on the winding segments 51 to form a gentle section 521, and the outer covering 52 is wound on the groove 53 to form a concave section 522; after the plurality of second warp yarns 21 are interwoven with the plurality of second weft yarns 22, the outer sides of two adjacent second weft yarns 22 and the concave sections 522 of two adjacent second warp yarns 21 form the second air-permeable through holes 23.

That is, in the lower fabric 2, the special second warp yarns 21 are interwoven with the ordinary second weft yarns 22 to form the lower fabric 2 having the second air-permeable holes 23, and the second air-permeable holes 23 of the lower fabric 2 are substantially in a strip shape through which the connecting thread 3 can pass. The second ventilation through hole 23 of rectangular shape makes connecting wire 3 pass the back, and the connecting wire 3 is great with the frictional force of second ventilation through hole 23 for connecting wire 3 is difficult for producing the displacement again, thereby improves surface fabric intensity.

As shown in fig. 8, as another example, each of the second warp yarns 21 and the second weft yarns 22 includes a core yarn 5, a plurality of winding segments 51, and an outer covering yarn 52, wherein each winding segment 51 is wound around the core yarn 5, a groove 53 is formed between the end portions of two adjacent winding segments 51 and the core yarn 5, the outer covering yarn 52 is wound around the winding segments 51 and the groove 52, the outer covering yarn 52 is wound around the winding segments 51 to form a gentle section 521, and the outer covering yarn 52 is wound around the groove 53 to form a concave section 522; after the plurality of second warp yarns 21 are interwoven with the plurality of second weft yarns 22, the concave sections 522 of two adjacent second weft yarns 22 and the concave sections 522 of two adjacent second warp yarns 21 form the second air-permeable through holes 23.

The square second ventilation through hole 23 has a larger aperture, so that the connecting line 3 can conveniently pass through. The second through-air-penetration through-hole 23 is formed by four concave sections 522 of the two second weft yarns 22 and the two second warp yarns 21, so that the aperture of the second through-air-penetration through-hole 23 is larger to facilitate the connection line 3 to pass through. It is noted that the second air-permeable perforations 23 in this example are small relative to the down feather, which does not come out of the second air-permeable perforations 23.

The first ventilating perforation 13 and the second ventilating perforation 23 in this example are arranged side by side, every several rows can be penetrated by a connecting line 3, the first ventilating perforation 13 and the second ventilating perforation 23 between two adjacent connecting lines 3 are not penetrated by the connecting line 3, and the first ventilating perforation 13 and the second ventilating perforation 23 between two adjacent connecting lines 3 are used for ventilation, so that the whole ventilation of the down jacket is excellent, the vapor in the wearing process is easy to diffuse, and the washed down jacket is easy to dry in the sun.

In summary, the upper layer fabric 1 may include two fabrics as shown in fig. 5 and 6, and the lower layer fabric 2 may include two fabrics as shown in fig. 7 and 8, and the upper layer fabric 1 and the lower layer fabric 2 may be combined in various ways. The upper layer fabric 1 in figure 5 is connected with the lower layer fabric 2 in figure 7 through a connecting line 3; the upper layer fabric 1 in figure 5 is connected with the lower layer fabric 2 in figure 8 through a connecting line 3; the upper layer fabric 1 in fig. 6 and the lower layer fabric 2 in fig. 7 are connected by a connecting line 3, and the upper layer fabric 1 in fig. 6 and the lower layer fabric 2 in fig. 8 are connected by the connecting line 3. Thus, four kinds of combination modes are provided, and different combination modes can be selected according to different requirements.

In some examples, the diameter of the core wire 5 is four to seven times the diameter of the wound wire segment 51. As shown in fig. 3, the diameter of the core wire 5 in this example is six times the diameter of the winding wire segment 51, so that after a plurality of winding wire segments 51 are wound on the core wire 5, the depth of the formed groove 53 is smaller than the diameter of the core wire 5, so that after the outer covered wire 52 is wound, the depth of the formed concave section 522 is more reasonable, and the pore diameters of the formed first air-permeable through hole 13 and the second air-permeable through hole 23 are moderate.

In the present example, the diameter of the core wire 5 is three to six times the diameter of the outer covered wire 52. As shown in fig. 4, the diameter of the core wire 5 in this example is five times the diameter of the outer covering wire 52, so that the first ventilation through-hole 13 and the second ventilation through-hole 23 formed after the outer covering wire 52 is wound around the groove 53 and the winding wire segment 51 have a moderate diameter. At the same time, the strength of the formed first weft yarn 12, first warp yarn 11, second weft yarn 22, or second warp yarn 21 is made greater.

In this example, after the wrapping wire 52 is wound around the winding wire 51 and the groove 53, the length of the gentle section 521 is six to eight times that of the concave section 522. As shown in fig. 4, in this example, the length of the gentle section 521 is seven times that of the concave section 522, so that the length of the gentle section 521 is longer, and the first ventilation through holes 13 and the second ventilation through holes 23 in the upper fabric 1 or the lower fabric 2 are reasonably distributed, and the whole ventilation performance is good.

In this example, after the first weft yarn 12 is interwoven with the first warp yarn 11 and the second weft yarn 22 is interwoven with the second warp yarn 21 by arranging the gentle sections 521, the gentle sections 521 in the formed fabric abut against each other, and loop threads on the outer side walls of the gentle sections 521 can be pressed and restricted with each other, so that the friction force can be increased, and the overall strength of the fabric is higher.

In some examples, the core wire 5 is made of polyurethane fibers, and the winding wire segment 51 and the covering wire 52 are made of cotton fibers. The core wire 5 made of polyurethane fiber makes the first weft 12, the first warp 11, the second weft 22 or the second warp 21 have better elasticity, and the winding segment 51 and the outer covering 52 made of cotton fiber make the first weft 12, the first warp 11, the second weft 22 or the second warp 21 have better heat preservation effect.

In order to improve the strength of the first weft yarns 12, the first warp yarns 11, the second weft yarns 22, or the second warp yarns 21, the winding direction of the over wrap 52 is opposite to the winding direction of the winding line segment 51. For example, the winding direction of the outer covering 52 may be clockwise winding, and the winding direction of the winding line segment 51 may be counterclockwise winding, so that the strength of the formed first weft 12, first warp 11, second weft 22 or second warp 21 is greatly improved, and the strength of the upper fabric 1 and the lower fabric 2 is enhanced. Of course, the winding direction of the outer sheath 52 in this example may be the same as the winding direction of the wound wire segment 51.

In some examples, the diameter of the connecting line 3 is equal to or slightly larger than the minimum diameter of the first through hole 13 and the second through hole 23, so that the connecting line 3 is connected with the upper layer fabric 1 and the lower layer fabric 2 more densely after the connecting line 3 passes through the first through hole 13 and the second through hole 23. The connecting wire 3 is preferably a strong wire.

The invention also provides a manufacturing method of the breathable light down jacket fabric, which comprises the following steps;

first, a plurality of winding wire segments 51 are wound on the core wire 5 by using a winding apparatus, and a groove 53 is formed between the end portions of two adjacent winding wire segments 51 close to each other and the core wire 5.

Secondly, winding the external covered wire 52 on the plurality of winding line segments 51 and the core wire 5 by using a winding device, wherein the external covered wire 52 is wound on the winding line segments 51 to form a gentle section 521, and the external covered wire 52 is wound on the groove 53 to form a concave section 522; the winding device winds the winding segment 51 and the outer covering 52 around the core 5 to form the first weft yarn 12, the first warp yarn 11, the second weft yarn 22 and the second warp yarn 21.

Thirdly, the first weft yarns 12 and the first warp yarns 11 are interwoven to form the upper fabric 1 through a weaving device, and the second weft yarns 22 and the second warp yarns 21 are interwoven to form the lower fabric 2.

And fourthly, laminating the upper layer fabric 1 and the lower layer fabric 2 together, and passing the connecting wires 3 through the first air-permeable through holes 13 and the second air-permeable through holes 23 under the action of a yarn lifting device to form a plurality of accommodating cavities 4 for accommodating the down.

In this example, the winding device is a conventional technology, the winding device may fix the core wire 5, and may wind the wire around the core wire 5, for example, the winding line segment 51 may be wound around the core wire 5, and the outer covering wire 52 may be wound around the winding line segment 51, and the winding device is a conventional technology and is not described herein again. The weaving equipment can interweave woof and warp, and it can lift the yarn to carry yarn equipment, and weaving equipment and carry yarn equipment are prior art, and this place is not repeated.

In this example, after the connecting thread 3 passes through the first ventilation through hole 13 and the second ventilation through hole 23, there is no seam, that is, the down is not exposed from the seam. The upper fabric 1 and the lower fabric 2 are independent of each other, and the fabric of the upper fabric 1 may be different from the fabric of the lower fabric 2. After the upper layer fabric 1 and the lower layer fabric 2 are manufactured, the fabrics can be further processed to improve the corresponding performance.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
