Abstract

Disclosed is a stereoscopic silk imitation fur fabric, comprising a real silk nap layer (1), a rayon base layer (2), a bonding layer (3), and an imitation leather nap layer (4), wherein the real silk nap layer (1) is fixedly connected with the upper part of the rayon base layer (2) by means of knitting, and the rayon base layer (2) is bonded to the imitation leather nap layer (4) through the bonding layer (3). The stereoscopic silk imitation fur fabric is formed by using a mulberry silk as a nap raw material and a rayon as a base layer raw material, weaving same using a circular machine, fixing a real silk nap layer onto a rayon base layer, and bonding same with an imitation leather nap layer. The real silk nap layer has a good gloss, a good stereoscopic structure and pattern effect, imparts a concave-convex stereoscopic perception to the fabric, has a smooth line, and has a good visual perception. The use of a rayon as a base layer material has a lighter weight and a lower cost compared to a silk. The fabric imitates an animal fur in which a natural silk ingredient is a protein, such that the sense of touch is more ideal on the skin; the air permeability is good; and furthermore, the fabric is more environmentally-friendly.

Description

Three-dimensional silk imitation fur fabric

Technical field

The invention relates to the technical field of textiles, in particular to a three-dimensional silk imitation fur fabric.

Background technique

Artificial fur is a plush fabric that looks similar to animal fur. It is an artificial animal fur made by artificial methods. Common manufacturing methods include knitting and weaving. Among them, the knitting weft knitting method has the fastest development and the most wide application. Acrylic fiber, modified acrylic fiber, chlorine fiber and other materials can be used as raw materials for artificial fur. Although artificial fur is not as warm as real fur, it is soft and beautiful, and can be made into coats, hats, collars, carpets, etc. It is widely used. At present, the popular imitation fur on the market is made of polyester or acrylic knitted by circular knitting into a gray fabric, and then brushed and brushed. The resulting product is hard and air-impermeable. Machine washing will lose hair and the gloss is poor. , The feel is poor, and the proportion of chemical raw materials is too large, resulting in poor quality of imitation fur.

Silk, a type of textile, is woven from silk or synthetic fibers, rayon, staple fiber, etc .; a general term for fabrics woven or interwoven with pure silk or rayon. The material used in this product is mulberry silk. The following silk refers to mulberry silk. Mulberry silk is the only filament fiber in natural fiber that can be mass-produced. It has easy processing characteristics that are unmatched by other fiber products in fabric processing and manufacturing. However, the existing silk is generally presented with a smooth cloth, which does not have a three-dimensional effect, which reduces the impact of the silk appearance on the human eye and the purchase volume of consumers. The use of single mechanical equipment for construction reduces the efficiency of its production and increases the cost of silk production. This product makes a breakthrough in traditional silk, making silk more than traditional flat fabric, making silk from 2D to 3D three-dimensional effect, and compared with animal fur, it has better breathability and is more environmentally friendly.
