Problems solved by technology

More importantly, if the imitation leather fabric uses elastic fibers as raw materials to prepare the surface layer to provide elasticity, and when the base layer uses non-elastic fibers, when the fabric is finished and shaped, it will cause the surface layer and the base layer to be inconsistent due to the elastic recovery of the surface layer and the base layer. The degree of shrinkage of the base layer is quite different, causing the fabric to wrinkle

Embodiment 1

[0049] A light-weight anti-compression warp-knitted elastic imitation leather fabric is obtained by compounding a warp-knitted sandwich structure fabric and elastic polyurethane coating, wherein the warp-knitted sandwich structure fabric is composed of the following mass percentage components: 100D PBT / PET composite yarn 32s cotton yarn is 37.1%, 30D monofilament polyester is 19.7%, 100D semi-gloss polyester DTY is 22.6%;

[0050] Concrete preparation process is as follows:

[0051] 1. Preparation process

[0052] Choose 100D PBT / PET composite yarn, 30D polyester monofilament, 32s cotton yarn, 75D36F semi-gloss polyester DTY, 100D semi-gloss polyester DTY.

[0053] 2. Warping process

[0054] Temperature and humidity at the warping site: temperature 25±2°C, relative humidity 65±3%, high and stable temperature and humidity are conducive to the generation of cotton yarn fly, polyester fiber surface is soft, less static electricity, avoid polyester fiber warping at high speed ...

Abstract

The invention discloses a light compression-resistant warp-knitted elastic imitation leather fabric and a preparation process thereof, and belongs to the technical field of warp-knitted imitation leather fabrics and production thereof. According to the invention, a four-bar two-needle bar warp knitting machine is used for weaving an integrated warp-knitted sandwich-structured fabric as a base material of the leather-imitating fabric, and the base material is compounded with an elastic polyurethane coating to obtain the light compression-resistant warp-knitted elastic leather-imitating fabric; wherein the guide bar GB1 and the guide bar GB2 are fully penetrated and only form a surface layer on a front needle bed through yarn laying; the guide bar GB3 is connected with the front and rear needle beds in a full penetrating manner to form a sandwich-structured core layer; a guide bar GB4 is fully penetrated and only loops on a rear needle bed to form a base layer; the guide bar GB1 adopts elastic yarns, and the guide bar GB2, the guide bar GB3 and the guide bar GB4 adopt non-elastic yarns; meanwhile, a sinker with two piece jaws is adopted in the weaving process, the piece jaw 1 is higher than the piece jaw 2, the elastic yarn passes through the piece jaw 1, the non-elastic yarn passes through the piece jaw 2, and the let-off amount of the elastic yarn is 600-800 larger than that of the non-elastic yarn.

Description

technical field [0001] The invention relates to a light anti-compression warp-knitted elastic imitation leather fabric and a preparation process thereof, belonging to the technical field of warp-knitted leather-like fabric and its production. Background technique [0002] The imitation leather fabric with a certain thickness generally has a three-layer structure. The first layer uses knitted fabric as the surface layer, the core layer uses sponge or other elastic materials, and the third layer uses superfine fiber non-woven fabric or woven plain weave as the base layer. The surface layer, core layer, and base layer are bonded by adhesive, and the base layer is compounded with elastic polyurethane. The processing process is long, the production cost is high, and it is difficult to meet the requirements of environmental protection and green production. Moreover, the superfine non-woven fabric or woven plain weave of the base layer has no extensibility and elasticity, and is in...
