High-elasticity floating-process warp-knitted base cloth and elastic genuine-leather-imitated fabric thereof

Abstract

The invention provides high-elasticity floating-process warp-knitted base cloth and an elastic genuine-leather-imitated fabric thereof. The elastic genuine-leather-imitated fabric comprises an elasticstress layer, a high-elasticity non-woven fabric layer, an elastic decoration layer and a bonding layer, wherein the elastic stress layer is the high-elasticity floating-process warp-knitted base cloth. The high-elasticity non-woven fabric layer is a TPU (Thermoplastic Polyurethane) melt-blown non-woven fabric made of a TPU material. The elastic decoration layer is formed through coating the high-elasticity non-woven fabric layer with the TPU material. The elongation percentage of the high-elasticity stress layer is smaller than that of the TPU melt-blown non-woven fabric. The high-elasticityfloating-process warp-knitted base cloth is composed of two bundles of comb lining warp yarns and lining weft yarns, and one bundle of comb binding yarns. The lining warp yarns are polyester light-network or network-free DTY and the lining weft yarns are polyester high-shrinkage DTY; the binding yarns are polyester middle-network or light-network DTY. The high-elasticity stress layer of the elastic genuine-leather-imitated fabric provided by the invention is prepared by the high-elasticity floating-process warp-knitted base cloth so that the elastic genuine-leather-imitated fabric has tearingresistance, a good hand feeling and a better appearance.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a high-elastic float warp-knitted base fabric and its elastic imitation leather fabric. Background technique [0002] Whether in the field of clothing or interiors such as car interiors and furniture interiors, genuine leather fabrics are the ultimate enjoyment that people are looking for, but genuine leather fabrics have their own shortcomings. For example, genuine leather has the smell of natural animal skin and the obvious smell left by complex chemical reactions during tanning, so its environmental protection is worth considering. As we all know, after depilation, the dermis can be cut into two or more layers. Not exactly consistent, therefore, poor consistency and poor continuity. Although the two-layer leather or multi-layer leather can maintain a certain degree of natural elasticity and process plasticity, its strength is poor, and the bonding fastness between the coati...

Problems solved by technology

As we all know, after depilation, the dermis can be cut into two or more layers. Not exactly consistent, therefore, poor consistency and poor continuity

Although the two-layer leather or multi-layer leather can maintain a certain degree of natural elasticity and process plasticity, its strength is poor, and the bonding fastness between the coating layer and the natural leather layer is also a problem, so the wear resistance is poor, and it is easy to delaminate.

[0003] In order to solve the above-mentioned shortcomings of leather fabrics, imitation leather fabrics have been developed, such as coating PU, PVC and other resin layers on the textile base fabric, and then processed into imitation leather appearances, but the current artificial leather fabrics are more expensive than genuine leather. Dense, poor air permeability, stiff feel, no or insufficient elasticity, impervious to moisture

In order to solve this problem, superfiber PU synthetic leather has been developed, which is made of a layer of high-performance PU resin and superfiber base cloth. It is the closest to the structure of natural leather, but its deformation recovery ability is poor. When subjected to tension, it is easy to leave traces and affect the appearance. It is not suitable for use in the field of clothing or high-end interiors such as car interiors
