Novel warp knitting fabric

Abstract

The invention provides a novel warp knitting fabric. The novel warp knitting fabric comprises a fabric body formed by knitting of at least three guide bars of a warp knitting machine, the fabric bodycomprises a surface layer and a bottom layer, the surface layer is formed in the mode that a group of yarns Y1 composed of a plurality of yarns is knitted and formed on the front face of the fabric body by means of a warp satin weave structure through the first guide bar, a group of yarns Y2 composed of a plurality of yarns are knitted by using a variable double-loop-stitch structure through the second guide bar and a group of yarns Y3 composed of a plurality of yarns is knitted by using a pad-lacking weft insertion weave structure through the third guide bar, and then the bottom layer is formed through co-forming of the yarns 2 and the yarns 3 on the bottom surface of the fabric body, wherein the yarns Y1, the yarns Y2 and the yarns Y3 are connected with each other in a penetrating and sleeving manner, and any two or three groups of the yarns Y1, the yarns Y2 and the yarns Y3 are elastic yarns. The fabric has the advantages of being not prone to edge curling and loosening and having elasticity in the warp and weft directions larger than or equal to 80%, the utilization rate of the fabric is increased, the garment manufacturing cost is reduced, and the garment wearing comfort and attractiveness of consumers are improved.

Description

technical field [0001] The invention belongs to the technical field of warp-knitted fabrics, and relates to a new type of warp-knitted fabric, specifically a kind of warp-knitted fabric that is not easy to curl, unravel, Fabrics with characteristics such as warp and weft elasticity ≥ 80%. Background technique [0002] Now, knitted fabrics have been widely used in the production of underwear, outerwear, and sports and leisure clothing. However, most knitted fabrics have the problem of curling and easy detachment after cutting. Therefore, it is usually necessary to trim the edges of the fabric after cutting, such as Neckline, armpits, cuffs, hem, trouser legs and other parts are overlaid, so that there is a lot of waste in the fabric, which not only increases the process and time of making garments, but also increases the production cost, especially when knitted fabrics are used for underwear. , when consumer is wearing, also can cause clothing to the extruding of body becaus...

AI Technical Summary

Problems solved by technology

This kind of fabric uses different raw materials, and adopts a two-needle open warp flat structure, and the direction of the two bar laying yarns is the same, which increases the variety of designs and colors of free-cutting fabrics. However, it is known in the industry that the same open warp flat structure will Make the fabric very easy to crack and the weft curling is serious

[0005] CN109881350A discloses a free-cut warp-knitted elastic fabric, using two bars of a warp knitting machine to weave, using non-elastic yarns and elastic yarns respectively, the first bar adopts a two-needle warp-flat structure, and the second bar uses Two stitches in the same direction are flattened to achieve the effect of free cutting. The shortcoming of this kind of free cutting fabric is the same as that of CN109137249A, that is, it is well known in the industry that the two combs all adopt the same direction warp flat structure and there is a greater risk of cracking and Serious weft curling

This arbitrary cutting fabric improves the shortcoming that CN109137249A and CN109881350A are easy to crack in structure, but it creates a new problem: the fabric surface of this kind of warp velvet with heavy warp structure is very easy to pile up and fall down, and it is scratched when touched. Good, but the elasticity is not superior enough

[0012] It is precisely because these shortcomings have not been effectively solved that the random-cut fabrics have encountered great difficulties in the actual production and application process, and cannot meet the increasing consumer demand in the market.
