Special process for dyeing and finishing multi-F viscose rayon

Abstract

The invention relates to a special process for dyeing and finishing multi-F viscose rayon, comprising the following steps of desizing by using sodium carbonate, neutralizing by using glacial acetic acid, rinsing by using tap water and the like. After the multi-F viscose rayon is specially dyed and finished, fabrics woven by the multi-F viscose rayon has a silk-imitating effect superior to that of fabrics woven by cuprammonium rayon raw materials produced in Japan, and the fabrics woven by the fibers have the advantages of favorable smoothness, air permeability and moisture absorption and bright luster after dyed.

Description

technical field

[0001] The invention relates to a dyeing and finishing process of poly-F viscose rayon and belongs to the technical field of rayon. Background technique

[0002] Viscose rayon belongs to a large category of cellulose fibers. Since the beginning of the 20th century, viscose fiber, which came out to solve the shortage of cotton, has been widely used in various textile fabrics, but because its feel cannot achieve the effect of real silk, this Such fabrics have been at the middle and low level. In recent years, affected by factors such as health and environmental protection awareness and advocating nature, people have a new understanding of regenerated cellulose fibers, and the application of cellulose fibers has reappeared a rapid growth. Especially after 2006, the imitation silk fabrics woven by Asahi Kasei’s raw materials of copper ammonium wire are in short supply at home and abroad. This has greatly hindered the market development of domestic cupro fabrics...
