Method for weight-increasing and antimicrobial treatment of silk fiber

Abstract

The invention discloses a method for weight-increasing and antimicrobial treatment of silk fiber, comprising: the preparing of silk fiber, degumming, washing, weight increasing treatment, soaping, dyeing, antibacterial treatment and after-finishing, wherein the weight-increasing treatment is performed at high temperature and pressure, the high temperature is 85 to 90 DEG C, in the weight increasing treatment, a grafting solution is firstly prepared and contains methacrylate ester derivatives as grafting monomer, a initiator, a non-ion or anionic surfactant and degumming waste water. In the invention, the drained degumming waste water can be recycled, thus saving the resource, reducing the pollution, improving the efficiency, and according with the requirement of circular, economical and clean production. In the invention, the weight increasing treatment for the silk fiber is performed, at the same time, the antimicrobial treatment is also completed, thus the treated silk fiber has theideal weight-increasing effect and a certain of antimicrobial performance.

Description

technical field [0001] The invention relates to weight gain modification and finishing of real silk fibers, in particular to a method for weight gain and antibacterial treatment of real silk fibers. Background technique [0002] The raw material of real silk is silk. Silk fiber is mainly composed of two proteins, silk fibroin and sericin. The dyeing process of real silk fiber adopts the processing method of removing sericin first, but after the sericin on the surface of the silk fiber is removed through refining, The weight of silk fiber is reduced and the fiber becomes thinner, so that the silk fabric has defects such as poor abrasion resistance, poor wrinkle recovery, and poor washability. Durability, wrinkle resistance, firmness and body. [0003] At present, the processing methods of weight-increasing silk fibers mainly include the following two types: one is to carry out chemical grafting on silk fibers, so as to increase the weight of fibers and improve the wearabilit...

AI Technical Summary

Problems solved by technology

[0004] If the degumming wastewater produced by refining silk fibers to remove sericin is directly discharged, it will not only cause great pollution to the environment, but also waste the sericin resources in it. Generally, a relatively high concentration of chemical reagents is required to achieve a better effect, and high concentrations of chemical reagents increase the difficulty of subsequent sewage treatment. Therefore, there are great shortcomings in the method of using chemical reagents to fix sericin. Currently, silk fibers are still mainly used for weight gain. The first type of processing method, but in terms of both achieving the purpose of silk weight gain and recycling degumming wastewater, there is no effective solution at present, and the currently commonly used silk weight gain methods are only dedicated to weight gain research, so that after weight gain The antibacterial properties of silk fibers are generally poor, which limits the use of silk fabrics
