A viscose fiber denaturing agent

Abstract

The invention relates to a denaturing agent for viscose. The denaturing agent comprises components in parts by weight as follows: 36-49 parts of N-Polyoxyethylated-N-tallow-alkylamine, 14-28 parts of polyethylene glycol lauramine, 12-23 parts of fatty alcohol-polyoxyethylene ether, 6-17 parts of polyethylene glycol and 5-10 parts of water. With the adoption of the denaturing agent for the viscose, the forming state during viscose spinning can be effectively changed, regeneration of cellulose is delayed, thickening of a fiber skin layer is promoted, a viscose stock solution can have a higher tensile property, and the dry-wet strength and wet modulus of fibers are increased.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a viscose fiber denaturant. Background technique [0002] When viscose fiber is applied, it is prone to severe swelling in wet state, low wet strength and low wet modulus, resulting in poor washing deformation, poor dimensional stability, and not alkali resistance. After alkali treatment, the strength and wet modulus decrease significantly, and the elongation at break long rise. In the viscose or coagulation bath, adding a denaturant that can inhibit the regeneration of cellulose xanthate can adjust the ratio of the diffusion speed of the coagulant component, the formation speed of macromolecular aggregates and the precipitation speed in the longitudinal velocity field relationship, delaying cellulose regeneration, promoting the increase in the thickness of the fiber cortex, increasing the degree of orientation of the fiber, enabling the nascent fiber to wi...

AI Technical Summary

Problems solved by technology

[0004] The research and development of denaturants in my country obviously lags behind the international ones. Domestic viscose fiber manufacturers mainly rely on foreign imports. The application costs are high and the technical constraints are strong, which greatly restricts the development of the domestic viscose fiber industry.
