Silk broadcloth grafted cation process

Abstract

The invention discloses a silk broadcloth grafted cation process. The method comprises the following steps of: performing grafting reaction on the preprocessed silk broadcloth fabric and a grafting agent at the temperature of 120 DEG C for 30 minutes, wherein the concentration of the grafting agent is 160 percent owf, and the pH value of the grafting agent is 9; and rolling and drying the grafted silk broadcloth fabric, curing at the temperature of between 60 and 70 DEG C for one hour, taking out, washing and drying. The bath ratio of the silk broadcloth fabric to the grafting agent is 1 to 40. The grafting agent is 1,2,3 glycidyl trimethyl ammonium chloride. In the process, the silk is grafted and is subjected to cationic modification, so that the silk dye-uptake and fixation rate of reactive dye can be improved; and the method has the advantages of saving energy, and contributing to clean production and environmental protection, along with simplicity and high efficiency and has wide application prospect.

Description

technical field [0001] The invention relates to a process for grafting cations on real silk, which belongs to the technical field of textiles. technical background [0002] Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc. Silk is known as the "fiber queen", and has been favored by people throughout the ages for its unique charm. Silk is a protein fiber. Silk fibroin contains 18 kinds of amino acids that are beneficial to the human body, which can help the skin maintain the metabolism of the lipid film on the surface, so it can keep the skin moist and smooth. Wearing silk clothes can not only prevent ultraviolet radiation, prevent the invasion of harmful gases, and resist harmful bacteria, but also enhance the vitality of skin cells on the body surface, promote the metabolism of skin cells, and have a good auxiliary treatment effect on certain skin diseases. In addition, due to the special hygroscopicity and air permeabili...

AI Technical Summary

Problems solved by technology

[0003] Silk is a traditional high-grade clothing fabric. Silk dyed with traditional acid dyes, direct dyes, and mordant dyes is easy to fade, but silk dyed with reactive dyes has a high color fastness. With the development of science and technology, It is found that there are some deficiencies in the existing silk printing and dyeing process

Because reactive dyes need to use a lot of salt to promote dyeing, and the dyeing rate and fixation rate are still low, and a large amount of printing and dyeing wastewater is generated, which is a waste of resources and is not conducive to environmental protection.
