[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1:

[0031] like Figure 1 As shown, a highly efficient down-proof horizontal pocket fabric is made of two layers of fabric, a first part A and a second part B, and a layer-changing point C. The first part A and the second part B are formed by exchanging the layers at the layer-changing point C. The first part A and the second part B are formed by exchanging the outer warp and inner warp layers, not exchanging the outer weft and inner weft layers, or exchanging the layers, or not exchanging the outer warp and inner warp layers, not exchanging the outer weft and inner weft layers, or exchanging the layers.

[0032] Furthermore, the outer weft is a coarse weft yarn or a fine weft yarn or a combination of both, and the inner weft is a coarse weft yarn or a fine weft yarn or any combination of both.

[0033] Furthermore, the first part A and the second part B include a first fabric layer and a second fabric layer. When weaving the first fabric layer, the outer warp is raised and interwoven with the coarse or fine weft yarn to form the first fabric layer, while all the inner warp is lowered and does not interweave with the coarse or fine weft yarn. When weaving the second fabric layer, the inner warp is interwoven with the coarse or fine weft yarn to form the second fabric layer, while all the outer warp is raised and does not interweave with the coarse or fine weft yarn. The interweaving of the inner warp with the coarse or fine weft yarn is manifested in that part is lowered and part is raised, forming a weave edge.

[0034] When changing layers in weaving, the upper and lower positions of the outer warp and inner warp are exchanged, while the upper and lower positions of the weft yarns are not exchanged or are exchanged; or the upper and lower positions of the outer warp and inner warp are not exchanged, while the positions of the weft yarns are not exchanged or are exchanged.

[0035] Furthermore, several coarse weft yarns are used at the layer change point to increase the yarn coverage per unit area.

[0036] Furthermore, the first fabric layer and the second fabric layer are connected to each other through the layer-changing point to form a first accommodating space D and a second accommodating space E. The first accommodating space D and the second accommodating space E can accommodate filling materials, such as down, cotton, and silk floss, or they can be left unfilled.

[0037] Furthermore, such as Figure 2 As shown, Figure 2 The diagram illustrates a single interlacing pattern. G represents a layer change point, where the warp and weft threads of the outer and inner layers of fabric are interlaced according to yarn density and warp-weft ratio. The outer weft consists of coarse weft yarn 1 and fine weft yarn 2, and the inner weft consists of coarse weft yarn 1 and fine weft yarn 2. In the diagram, the positions of the outer and inner warp yarns are interchanged, but the weft yarn positions remain the same.

[0038] Furthermore, such as Figures 3-4 In the process of changing layers during weaving, the upper and lower positions of the outer warp and inner warp are exchanged, while the upper and lower positions of the weft yarn are not exchanged. Blank areas indicate that the weft yarn covers the warp yarn, and non-blank areas indicate that the warp yarn covers the weft yarn. Figure 3 The displayed area shows a structure where the front and back warp layers are interchanged, but the front and back weft layers are not interchanged. The interchanged areas are structural examples of facet connections. Multiple accommodating spaces D and E can be arranged with the same or different pocket widths and the same or different spacing by changing the number of times n of the fabric repeats the transverse pocket fabric. Figure 4 The diagram shows a structure where the front and back warp layers are interchanged, while the front and back weft layers are not interchanged, with the interchanged areas connected by lines. The size of the accommodating spaces D and E can be adjusted by setting the number of fabric cycles n for the transverse pocket fabric, allowing the multiple pocket areas to appear at intervals with the same or different pocket widths and the same or different spacing.

[0039] Furthermore, such as Figures 5-6 During weaving, when changing layers, the upper and lower positions of the outer and inner warp yarns are not exchanged, nor are the positions of the weft yarns. Blank areas indicate that the weft yarns are covering the warp yarns, while non-blank areas indicate that the warp yarns are covering the weft yarns. Figure 5 The diagram shows a structural example where the front and back warp yarns do not interchange vertically, and the weft yarns do not interchange horizontally. The size of the accommodating spaces D and E can be adjusted by setting the number of fabric cycles n for the transverse pocket fabric, so that the multiple pocket areas appear at intervals with the same or different pocket widths and the same or different spacing. Figure 6The diagram shows a structural example where the front and back warp yarns do not exchange positions, and the weft yarns do not exchange positions. The size of the accommodating spaces D and E can be adjusted by changing the number of fabric cycles n of the transverse pocket fabric, so that the multiple pocket areas appear at intervals with the same or different pocket widths and the same or different spacing.

[0040] Furthermore, several coarse weft yarns are used at the layer change point to increase the yarn coverage per unit area.

[0041] Furthermore, the warp density of the outer warp and inner warp is 50 to 500 threads / cm, and the weft density of the outer weft and inner weft is 50 to 500 threads / cm.

[0042] Furthermore, the fabric structure of the horizontal pocket fabric can be a three-layer structure, a three-layer variation structure, or a multi-layer structure. The three-layer structures are plain weave, twill weave, and satin weave. The three-layer variation structures include double plain weave, broken twill weave, and checks, etc. The multi-layer structure can be two, three, four, or more layers. A two-layer structure consists of two independent warp and weft systems: the outer warp and outer weft form the surface structure, and the inner warp and inner weft form the inner layer structure; both the surface and inner layer structures are three-layer structures or three-layer variation structures. A three-layer structure consists of three independent warp and weft systems: the outer warp and outer weft form the surface structure, the middle warp and middle weft form the middle layer structure, and the inner warp and inner weft form the inner layer structure; all three layers are three-layer structures or three-layer variation structures.

[0043] Furthermore, the fabric width of the horizontal pocket fabric is 100-300cm.

[0044] Furthermore, the pocket width of the fabric of the transverse pocket is 0.1cm to 100cm.

[0045] Furthermore, the yarn used in the fabric of the transverse pocket is a recycled or non-recycled chemical fiber or a recycled or non-recycled natural fiber.

[0046] The recycled chemical fibers include recycled polyester staple fiber, recycled polyester filament, recycled nylon staple fiber, recycled nylon filament, etc.

[0047] The non-regenerated chemical fibers include non-regenerated polyester staple fiber, non-regenerated polyester filament, non-regenerated nylon staple fiber, non-regenerated nylon filament, etc.

[0048] The regenerated or non-regenerated natural fibers include wool fibers or cotton fibers, etc.

[0049] The above uses fabrics of different materials, which can combine the advantages of different fabrics to obtain downproof fabrics that meet different other needs.

[0050] Furthermore, the warp yarns of the first and second fabric layers are threaded using a straight threading method or other techniques, with the outer and inner warp yarns threaded in the same area, or the outer and inner warp yarns not in the same area.

[0051] Furthermore, the warp and weft yarns are interwoven and combined according to the warp and weft yarn density and warp and weft arrangement to form the layer change area. The arrangement includes the ratio of the number of warp and weft yarns and the ratio of the thickness of the warp and weft yarns.

[0052] Furthermore, the number of roots for the outer warp and the inner warp are set in a proportional manner, and the number of roots for the outer weft and the inner weft are set in a proportional manner.

[0053] Furthermore, the fabric has a denier (D) to fiber (F) ratio of less than 3 for long fibers and a fineness of 30 to 120 for short fibers. D represents fineness; a higher D number indicates a coarser fiber. F represents the number of fibers per filament; for fibers with the same D number, a higher F number indicates a softer fabric. The down-proof fabric of this application uses recycled or non-recycled chemical fibers or recycled or non-recycled natural fibers, with warp densities of 50 to 500 threads / cm for both the outer and inner warps, and weft densities of 50 to 500 threads / cm for both the outer and inner wefts, thus achieving a down-proof effect.

[0054] Furthermore, a nano-anti-fouling and anti-static fabric layer is provided on the first fabric layer.

[0055] Furthermore, the first fabric layer and the second fabric layer are woven using plain weave, square plain weave, or twill weave, respectively.

[0056] The first and second fabric layers are constructed by exchanging layers at the layer-changing point C. This involves either exchanging the warp and weft layers, or not exchanging the warp and weft layers, or not exchanging the warp and weft layers, or exchanging the warp and weft layers, or exchanging the warp and weft layers. These layers interweave to change the positions of the warp and weft yarns, simultaneously connecting the two layers into a single unit. The first fabric layer is located on the upper surface of the first accommodating space, and the second fabric layer is located on the lower surface of the first accommodating space. After the layer-changing weaving, at the second accommodating space, the warp and weft layers are either exchanged, or not exchanging the warp and weft layers, or not exchanging the warp and weft layers, or exchanging the warp and weft layers.

[0057] In the above embodiments, the layer transition points can be formed by two adjacent parallel lines, but this is not a limitation. Adjacent lines can also intersect, i.e., they can be set into any shape, depending on the requirements. Furthermore, the multiple lines of the downproof fabric in this application can also form vertical stripes or squares of varying widths, depending on the specific needs. The width of the first fabric layer and the second fabric layer is the same.

[0058] like Figure 7 As shown, Figure 7 This is a schematic diagram of the circular weave structure of the transverse pocket fabric of the present invention, which is a highly efficient down-proof material.Figure 7 In this invention, F represents coarse yarn and H represents fine yarn, allowing the warp and weft threads to be interwoven or interchanged, or interwoven without changing layers. The schematic diagram of the repeating structure of the high-efficiency down-proof transverse pocket fabric of this invention shows that the size of the first and second accommodating spaces can be adjusted by setting the number of repeats (n) of the first and second accommodating spaces, so that the multiple first accommodating spaces D and second accommodating spaces E are distributed with different or the same pocket width, and the intervals between the first accommodating spaces D and second accommodating spaces E appear in the same or different ways. The number of repeats (n) of the basic structure of the transverse pocket fabric is 1 to 10,000.

[0059] Furthermore, this invention utilizes unique high-performance weaving equipment and a unique weave structure, formed by the interweaving of numerous warp and weft yarns, creating a... Figure 1 The first part A, the second part, and the layer change point C are shown.

[0060] When weaving the first fabric layer, the outer warp is lifted and interwoven with either thick or thin weft yarns to form the first fabric layer, while all inner warp yarns are lowered and do not interweave with either thick or thin weft yarns. When weaving the second fabric layer, the inner warp yarns interweave with either thick or thin weft yarns to form the second fabric layer, while all outer warp yarns are lifted and do not interweave with either thick or thin weft yarns. At the layer transition point, the upper and lower positions of the outer and inner warp yarns are exchanged, while the upper and lower positions of the weft yarns are either not exchanged or are exchanged, or the upper and lower positions of the outer and inner warp yarns are not exchanged, while the weft yarn positions are either not exchanged or are exchanged. With people's increasing demand for personalized, functional, comfortable, and aesthetically pleasing clothing, the method provided by this invention brings technological innovation to the field of down jacket fabrics. The accommodating space formed by the fabric structure can accommodate the filling material, eliminating the need for quilting, shortening the production process of down jackets, increasing efficiency, reducing labor costs, ensuring stable and reliable quality, achieving a highly effective down-proof effect, and resulting in a perfect garment finish.
