Abstract

The invention relates to a collagen-PVA composite fiber top dyeing method comprising the technical steps that: 1, a Lannasol dye produced by Huntsman Textile Effects (China) Co., Ltd is used in fiber top dyeing; 2, collagen-PVA composite fiber tops are loosened, and are placed in a normal-temperature top dyeing machine; the temperature is increased, and glacial acetic acid is added into the machine; the machine is started, and the temperature is increased to 78-82 DEG C; the temperature is maintained for 20-30min, and is reduced to 65 DEG C; soda ash is added to the machine, and the machine is started; mirabilitum dehydratum is added three times into the machine, and soda ash is added twice into the machine, wherein a bath ratio is 1:20-50; 3, post-processing is carried out, wherein the dyed collagen-PVA composite fiber tops are places in soaping liquid 209, and is processed for 20-30min under a temperature of 90-100 DEG C; the collagen-PVA composite fiber tops are washed, and are placed in glacial acetic acid; the fiber tops are processed for 10min under a temperature of 38-42 DEG C, wherein a bath ratio is 1:20-1:50. With the method, a dye complete-absorption rate can be improved, dyeing uniformity and stability can be improved, and a dyeing effect is better.

Description

Technical field [0001] The invention relates to a dye selection for the stripe dyeing of collagen-PVA composite fiber, the selection of the auxiliary agent corresponding to the dye dyeing in the dyeing, and the matching dyeing and post-treatment process. It belongs to the technical field of fiber dyeing. Background technique [0002] In recent years, the research on the production of fiber from various organisms has become popular in Europe, America and Japan. Among them, collagen fiber has attracted more and more attention due to its unique advantages. As a natural polymer material, collagen can be directly used to prepare fibers, but pure collagen has poor fibrillation, low strength, difficult spinning, and high cost, which limits its application. In order to improve its spinnability and fiber mechanical properties, polymer materials such as PVA, polyacrylonitrile and other composite spinning are usually added. As a fiber-forming polymer with good spinnability and mechanical ...
