Embodiment 1

[0013]Embodiment 1: A production method of cuproammonia and PHBV blended fabrics, including the following steps: Step A): Select 50 denier to 150 denier PLA, PHBV and cuproammonium filaments to form nail mixed filaments, wherein the nail mixed long PHBV filaments in the silk account for 20% of the first mixed filaments, cuproammonia yarns account for 25% of the first mixed filaments, choose 50 denier to 150 denier PLA and PHBV to form second mixed filaments, wherein the second mixed filaments The medium PHBV filament accounts for 30% of the second mixed filament, and finally selects 50 denier to 150 denier cupro ammonia wire. Step B): Warping the mixed filaments A, mixed filaments B and the cupro ammonia wires by a batch warping machine, the number of warping threads of the batch warping machine is 720 , during the warping process, the winding tension is greater than the unwinding tension, and the winding tension is 1.1 times of the unwinding tension. After the warping is com...

Abstract

The invention discloses a method for producing copper ammonia and PHBV blended fabric, and relates to a method for producing textile fabric. The method includes the following steps: (1) selecting blended filaments with different PHBV proportions and copper ammonia yarns, (2) carrying out warping processing on the blended filaments and the copper ammonia yarns, (3) carrying out sizing processing on the blended filaments and the copper ammonia yarns, (4) carrying out warp re-beaming processing on the blended filaments and the copper ammonia yarns, and (5) carrying out silk drawing and reed inserting processing on the blended filaments and the copper ammonia yarns, and carrying out spinning to obtain the fabric. Compared with the prior art, the fabric produced with the method is low in cost and high in degradable degree, and can be generally and completely degraded within five years to ten years after being abandoned; meanwhile, the fabric is flexible in touch and elegant in gloss, the quality of the fabric is similar to that of real silk, the strength and the size stability of the fabric are much better than the strength and the size stability of the real silk, and the fabric is a woven product quite suitable for the fast fashion concept.

Description

technical field [0001] The invention relates to a method for producing a textile fabric, in particular to a method for producing a PHBV fabric. Background technique [0002] Cupro fiber is a kind of regenerated cellulose fiber. It is made by dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. Silk fibroin molecular chemicals decompose and regenerate cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro ammonia silk. PHBV is a copolymer of new biopolymers 3-hydroxybutyrate and 3-hydroxyvalerate. It is a biological material produced by using starch as raw material and using fermentation engineering technology. is a bio-polyester, which is produced by bacteria, can be digested by bacteria, and completely decomposes into carbon dioxide, water and biomass under soil or composting conditions. PHBV fiber is a low-energy product, ...
