Embodiment

[0021] A preparation method of Bemberg fiber, comprising the following steps:

[0022] 1. Dissolving natural cellulose raw materials such as cotton linters in the concentrated ammonia solution of copper hydroxide or basic copper salt is made into spinning solution; the basic copper salt includes basic copper carbonate, basic sulfuric acid copper.

[0023] 2. In the coagulation bath, the molecular chemical cuproamide cellulose is decomposed and regenerated into cellulose through water evaporation, shear action and elevated temperature,

[0024] 3. Post-processing the cellulose hydrate generated in step (2): extruding the cellulose hydrate solution through a die to form a continuous filament bundle;

[0025] 4. The tow is dissolved in a water bath to remove impurity components;

[0026] 5. The tow is compressed and crimped, and finally cut to obtain the Bemberg fiber of the present invention.

[0027] The technical index of the Bemberg fiber that preparation method of the pre...

Abstract

The invention provides a new Bemberg fiber and a preparation method thereof: dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt, making spinning solution, and spinning in a coagulation bath The cupro ammonia cellulose molecular chemical decomposes to regenerate cellulose, and the resulting hydrated cellulose is post-processed to obtain Benbemberg fiber. Bemberg fiber is a cellulose fiber made of cotton linters, which is organically decomposable and very beneficial to the protection of the natural environment. Moreover, the preparation process of the present invention is simple, low in cost and high in yield.

Description

technical field [0001] The invention relates to the technical field of textile fiber manufacturing, in particular to a Bemberg fiber and a preparation method thereof. Background technique [0002] Bemberg fiber is also called Cuprammonuium fiber (Cuprammonuium), the English name is: BEMBERG is also expressed by Cuprammonium in some places, and it was originally developed and produced by Japan's ASAHI KASEI company. Bemberg fiber is a regenerated cellulose fiber made from linters extracted from cotton. It is a pure natural and environmentally friendly lining, which will not cause any harm to the skin, and can fully satisfy consumers who have high-performance requirements for linings. [0003] Bemberg fibers are slender, round in cross-section and neat like natural fibers. On the other hand, unlike cotton and rayon, the surface is porous, so it has excellent color development, moisture absorption and moisture release properties, and silky smoothness and luster. The hygrosco...
