Health type viscose fiber with high wet modulus and its production process and use

Abstract

The present invention is composed of cellulose and chitin with weight ration 2-9:0.02-2. Alkalifying and etiolating cellulose and chitin obtain the xanthogenate of cellulose and chitin. Dissolving the said xanthogenate of cellulose and chitin in sodium of hydroxide and water makes spinning dope. Using wet spinning or wet pipe forming methods, after drawing procedure makes the fiber. The physical and mechanical performance of the fiber can be enhanced after treatment with simple technique. The fiber can fabricate textile and cloth providing features of antibiosis, stopping itch and bleeding, odor dispelling. Fibrous membrane made by mixed cellulose with chitin as raw material can be used in artificial organs or water purifier.

Description

Technical field:

[0001] The present invention relates to a kind of man-made fiber, specifically a kind of viscose fiber of health-care type with high wet modulus, its manufacturing technology and its application for making health-care fabric or hollow fiber membrane. Background technique:

[0002] Chitin was first discovered from mold by French scientist Braconnot in 1811, but because chitin is insoluble in general solvents such as water, dilute acid and alkali, its application performance is limited. It was not until the 1950s that we had a thorough understanding of the chemical structure, properties and manufacturing methods of chitin. It was found that chitin can be made into xanthate by yellowing method and dissolved in dilute alkali, thus expanding its application. range.

[0003] Chitin and its derivatives have health-care effects. With the continuous improvement of living standards and quality, people's demand for health-care fabrics is also increasing. The health-ca...
