Embodiment 1

[0049] Multi-F viscose rayon is woven into gray cloth by air-jet loom; the above-mentioned 300kg gray cloth is rolled into a jigger; 300kg of tap water is added; the water temperature is raised to 100°C by steaming; 8kg of soda ash is added; the jigger is started , make gray cloth in the environment that water temperature keeps 100 ℃, rotate 3 hours, water is discharged; Add 200kg water, add 5 kilograms of glacial acetic acid again and carry out neutralization, drain; Add 300kg tap water again, add 7kg again by 15% ( (mass percent) sulfuric acid (concentration is 95%--99%), 6% anhydrous zinc sulfate (mass percent) and 79% water (mass percent) composition; Water temperature is raised to 100 ℃ by steaming and Keep the water temperature at 100°C, turn the dyeing jigger for 2 hours, and drain the water; then add 300kg of tap water, and heat up to 60°C with steam; add 6kg of soda ash, start the dyeing jigger to run for 100 minutes, and then drain the water; then add 300kg Start the...

Embodiment 2

[0051] Multi-F viscose rayon is woven into gray cloth by air-jet loom; the above-mentioned 500kg gray cloth is rolled into a jigger; 300kg of tap water is added and 8kg of caustic soda is added; steam is used to raise the water temperature to 100°C; start jigger dyeing machine, keep the gray cloth in an environment with a water temperature of 100°C, rotate for 3 hours, and drain the water; add 200kg of water, add 6kg of glacial acetic acid for neutralization, and drain; re-add 200kg of tap water, and then add 8kg of 20% (mass percentage) sulfuric acid (concentration is 95%--99%), 10% anhydrous zinc sulfate (mass percentage) and 70% water (mass percentage) composition of the fluffing agent; Water temperature is raised to 100 ℃ by passing steam Keep the water temperature at 100°C, turn the dyeing jigger for 2 hours, and drain the water; then add 250kg of tap water, and heat up to 60°C; 400kg tap water to start the jigger and run it for 60 minutes, drain the water; dry; cut the f...

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...
