Description

Technical Field

[0001] The invention belongs to the technical field of knitted clothing fabrics and weaving, and specifically relates to a lace fabric with good permeability and no unraveling, and a weaving method. Background Art

[0002] Lace fabrics are increasingly popular among garment designers and wearers in the fashion industry due to their transparency, flexible and vivid patterns. However, since the base fabric structure of most traditional lace fabrics is a chain structure, it is easy to fall apart in the reverse weaving direction along the warp, which seriously affects its application in the clothing field. Can this problem be effectively improved or solved? According to relevant information, some manufacturers have made some improvements in production technology or conditions:

[0003] CN 107532350 A (Lace knitted fabric) provides a lace knitted fabric with good appearance and good hand feel. The contact part between the chain yarn and the first insertion yarn and the contact part between the chain yarn and the second insertion yarn are bonded to prevent the deformation of the grid.

[0004] CN 107287755 B (Weaving method of multi-comb warp knitting machine) proposes a weaving method of a multi-comb warp knitting machine, which adds an anti-loosening coil on the basis of the original coil, thereby increasing the tightness of the original coil. The connection points of each coil are staggered or overlapped, so that the ground mesh coil has a strong cohesion force and is more tightly cohesive with the fancy yarn forming the pattern structure. Even if no chain transfer horizontal line or hot-melt yarn is added, the damaged ground yarn coil and the fancy yarn are not easy to loosen.

[0005] CN 109505054 A (A non-hot-melt material lace fabric that can be cut at will), the fabric body of the invention comprises a main body woven by two filament combs and two spandex combs, the main body comprises a pattern layer woven by a patterned yarn comb with elastic yarn or filament weft-inserting structure or loop-forming structure, the main body is also provided with an elastic weft opening layer, a warp opening layer and a compact resistance layer, the fabric has the advantages of good warp and weft tensile performance, can be freely stretched in all directions and is not easy to fall apart after cutting.

[0006] Although the above three inventions have improved the above-mentioned debonding problem, the inventor believes that their solutions are still not perfect: according to CN 107532350 A, the raw materials used are all hot-melt materials with inconsistent melting points, and there are two groups of different core-spun yarns, so the entire production process of the invention is complicated (different melting points use different setting temperatures), not environmentally friendly (the setting machine will inevitably consume water and electricity and produce waste gas when working, and the more times, the greater the impact), and increase the production cost; according to CN107287755 B, it is necessary to add a set of warp feeding devices on the basis of existing equipment, which is bound to increase the technical difficulty and operating costs, and ultimately affect the sales price of the fabric, which is not conducive to the market competition of the fabric. According to CN 109505054 A, a pair of filaments and a pair of spandex are used together to form a braided chain structure to achieve the purpose of preventing debonding, but the workload of these two yarns in the actual warping, feeding, and threading links is too large, that is, the time consumption will inevitably increase, which is not conducive to production efficiency and production costs. Summary of the invention

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] As attached Figure 1-6 As shown, the present invention discloses a lace fabric with good permeability and no unraveling, including a fabric body, wherein the fabric body is woven from 5 groups of yarns, namely Y1 yarn, Y2 yarn, 3 yarn, Y4 yarn and Y5 yarn, which are interlaced with each other. Since the yarns are interlaced with each other, the coils formed by the yarns in the weaving process have a structure of mutual pulling, so that the fabric body has good anti-unraveling performance.

[0033] The Y1 yarn and the Y2 yarn are woven to form the looped jacquard pattern layer of the fabric body, the Y3 yarn is woven to form the pattern layer of the fabric body, the Y4 yarn and the Y5 yarn are woven to form the elastic layer that provides the warp elasticity for the fabric body, the knitted yarns of the looped jacquard pattern layer, the pattern layer and the elastic layer are mutually pulled to form an anti-loosening structure for the fabric body, and the looped jacquard pattern layer is provided with a plurality of holes of different sizes that make the fabric body permeable, thereby improving the permeability of the fabric body. As the surface layer of the fabric body, the pattern layer can be woven into different patterns as needed to play a decorative role.

[0037] When weaving the jacquard layer, the yarn on the jacquard bar is designed according to the process. In the actual weaving process, the warp flat structure is changed. The loops formed by the yarns in the weaving process form a pull structure with each other. The pull prevents the fabric from falling apart, and the holes in the weaving make the fabric have good permeability. Combined with the various patterns formed by the flower yarn and the symmetrical stretching effect of spandex in the warp direction to form an elastic layer, the final lace fabric will combine permeability, non-shedding and stretchability.

[0038] The composite yarn consists of a core yarn and a covering yarn, wherein the covering yarn covers the core yarn, the core yarn is spandex or other elastic yarns except spandex, and the covering yarn is nylon, polyester or other non-elastic yarns except nylon and polyester.

[0042] The Y4 yarn and the Y5 yarn are spandex, and the linear density is between 40-1200D.

[0043] A method for knitting a lace fabric with good permeability and no loosening, wherein five groups of yarns, namely, Y1 yarn, Y2 yarn, 3 yarn, Y4 yarn and Y5 yarn, are interlaced and knitted to form a fabric body, wherein:

[0044] The Y1 yarn and the Y2 yarn are woven with a warp-plain structure and opposite padding numbers to form a looped jacquard layer of the fabric body, and a plurality of holes of different sizes are formed to make the fabric body permeable.

[0045] The Y3 yarn is a patterned yarn comb cluster, which is woven with a 1-needle weft insertion structure to form the pattern layer of the fabric body.
