Pure copper ammonia fiber high-density imitated silk jacquard plus material and preparing method of pure copper ammonia fiber high-density imitated silk jacquard plus material

Abstract

The invention provides a pure copper ammonia fiber high-density imitated silk jacquard plus material and a preparing method of the pure copper ammonia fiber high-density imitated silk jacquard plus material. Warp yarns of the plus materials are copper ammonia 75D / 45F, weft yarns are copper ammonia 75D / 54F, the warp yarn density is 750 to 787 / 10cm, the weft yarn density is 630 to 709 / 10cm, the breadth is 250 to 340cm, the plus material is jacquard fabrics, the pattern width is 60 to 64cm, and the length is 90 to 100cm. The plus material is woven by a single weaving shaft of a rapier loom, the luster, the drapability, the ventilation performance and the hand feeling of the plus material are very similar to those of real silk, the breadth of the plus material is greater, in addition, the quality of the plus material on the whole breadth is identical, and front and back side defect spots do not exist.

Description

technical field [0001] The invention relates to a simulated silk fabric, in particular to a pure copper ammonia fiber high-density simulated silk jacquard fabric and a preparation method thereof. Background technique [0002] Imitation silk fabric has always been a fabric that people have worked hard to explore and develop in order to replace silk fabrics that are expensive and have limited production. In the past, differentiated polyester filaments were generally used to replace real silk, but polyester fabrics are very good in appearance, feel, and hygroscopicity. It is difficult to fully achieve the style and characteristics of real silk fabrics, so it has not been recognized by consumers. With the development of the green textile industry, new green and environmentally friendly regenerated natural cellulose fabrics have gradually gained people's favor. Natural cellulose raw materials such as velvet and various papermaking materials are dissolved in a concentrated ammonia...

[0002] Imitation silk fabric has always been a fabric that people have worked hard to explore and develop in order to replace silk fabrics that are expensive and have limited production. In the past, differentiated polyester filaments were generally used to replace real silk, but polyester fabrics are very good in appearance, feel, and hygroscopicity. It is difficult to fully achieve the style and characteristics of real silk fabrics, so it has not been recognized by consumers. With the development of the green textile industry, new green and environmentally friendly regenerated natural cellulose fabrics have gradually gained people's favor. Natural cellulose raw materials such as velvet and various papermaking materials are dissolved in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to make a spinning solution, and then sprayed and spun to produce man-made fibers. The surface of cupro ammonia fiber is smooth , soft luster, good moisture absorption and perspiration, soft hand feeling, good drapability, appearance and characteristics similar to real silk, it is an ideal raw material for anti-silk fabrics, currently only Asahi Kasei, Japan produces cupro ammonia fiber in the world, and the price per ton is 180,000-200,000 , the price is relatively expensive, which is equivalent to 1 / 2 of the price of real silk. Most of the cupro filaments supplied are in the untwisted state, which is difficult to twist and damages the quality of the yarn. This limits the weaving production and product design of cupro fibers It is very large, and generally can only be used as weft yarn, or blended with cupro staple fiber and pure cotton. In the clothing field, blended yarn of pure cotton and cupro ammonia staple fiber is often used to weave high-grade ladies shirt fabrics to reduce costs. It is easy to weave, but it is far from silk products in terms of luster and feel, and the warping, weaving, dyeing and finishing of cupro ammonia fiber filament fabrics need to adopt specific processes, and the requirements for machine status are very high, otherwise it will easily appear. The problems of "three evils of cupro ammonia", that is, wrinkles, easy to shrink, and not strong, limit the application of cupro ammonia fiber filaments. The high-grade wide-width imitation silk fabrics of pure cupro ammonia fiber filaments have not been reported yet, so pure cupro ammonia fiber filaments have not been reported. The development of high-grade home textile fabrics has broad market prospects
