Problems solved by technology

Cellulose viscose is easy to dye, not easy to generate static electricity, and has good spinnability. It is widely used in various fields such as textiles, clothing, and casings. However, the wet modulus of cellulose viscose is low, and the shrinkage rate is relatively low. Higher, dimensional stability, poor elasticity and wear resistance, easy to fluff, and not resistant to acid and alkali
[0003] Cellulose casings are cellulose viscose made of natural fibers such as cotton linters, sawdust, flax and other plant fibers. Under normal circumstances, it can also be smoked and roasted, but the cellulose casing is inedible, cannot shrink with the meat filling, has dimensional stability, poor elasticity and wear resistance, is easy to fluff, has low water vapor transmission rate, and is not resistant to acid and alkali. Inherent disadvantages limit the promotion and use of cellulose casings
[0004] In the prior art, the dimensional stability, abrasion resistance and acid and alkali resistance of cellulose viscose are mainly improved by surface treatment of cellulose viscose or the use of rich and strong fibers instead of viscose fibers, thereby improving the quality of cellulose casings. However, surface treatment will reduce the toughness and antistatic properties of cellulose viscose, while the high-strength fibers have low elongation at break, poor spinnability, and poor acid resistance; at present, there is no way to ensure the toughness and antistatic properties of cellulose casings. Improve the water vapor trans

Abstract

The invention discloses a preparation method of cellulose viscose and application of the cellulose viscose in cellulose casings, and belongs to the technical field of viscose, the preparation method of the cellulose viscose comprises the steps of viscose solution preparation, viscose solution modification, spinning and post-treatment; the application of the cellulose mucilage glue in the cellulose casing comprises the steps of weaving forming, sizing, primary drying, washing sizing and secondary drying. While the toughness, antistatic property and spinnability of the cellulose casing are improved, the water vapor permeability, wet modulus, dimensional stability, elasticity, wear resistance and acid and alkali resistance of the cellulose casing are improved.

Description

technical field [0001] The invention relates to the technical field of viscose fiber, in particular to a preparation method of cellulose viscose and its application in cellulose casings. Background technique [0002] Cellulose viscose is made of natural cellulose such as cotton pulp, wood pulp, bagasse pulp, hemp pulp, bamboo pulp, etc., and is made into soluble cellulose xanthic acid through alkalization, aging, yellowing and other processes Ester, then dissolved in dilute lye to make viscose, which is made by wet spinning. Cellulose viscose is easy to dye, not easy to generate static electricity, and has good spinnability. It is widely used in various fields such as textiles, clothing, and casings. However, the wet modulus of cellulose viscose is low, and the shrinkage rate is relatively low. Higher, dimensional stability, poor elasticity and wear resistance, easy to fluff, and not resistant to acid and alkali. [0003] Cellulose casings are cellulose viscose made of nat...
