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 the ideal weight-increasing effect and a certain of antimicrobial performance.

Description

Technical field [0001] The invention relates to the weight-increasing modification finishing of real silk fibers, in particular to a method for weight-increasing and antibacterial treatment of real silk fibers. Background technique [0002] The raw material of real silk is silk. The silk fiber is mainly composed of two kinds of proteins, silk fibroin and sericin. The dyeing process of silk fiber uses the processing method of removing the sericin first, but after removing the sericin on the surface of the silk fiber through scouring, The weight of silk fiber is reduced, and the fiber becomes thinner, so that the silk fabric has the defects of poor abrasion resistance, poor wrinkle recovery, poor washing and wearability, and the grafting of the silk fiber can also improve its antibacterial properties. Resistance, wrinkle resistance, stiffness and thickness. [0003] At present, the processing methods of weight-increasing silk fibers mainly fall into the following two categories: on...

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
