Abstract

The invention provides a mucilage glue emission-reduction type one-bath dyeing process, belonging to the technical field of spinning. The process comprises the steps of preparing composite desizing enzyme, preparing a substrate solution, preparing a desizing agent, dipping, carrying out thermal insulation desizing, washing, and the like. According to the mucilage glue emission-reduction type one-bath dyeing process, the desizing and one-bath dyeing purposes are achieved by virtue of a biological enzyme desizing method, so that the energy saving and theemission reduction are realized.

Description

technical field [0001] The invention relates to a viscose preparation method, in particular to a viscose emission reduction one-bath dyeing process. Background technique [0002] Viscose fiber is the full name of viscose fiber and viscose, and it is divided into viscose filament and viscose staple fiber. Viscose fiber belongs to regenerated cellulose fiber. It is made of natural cellulose as raw material. It is made into soluble cellulose xanthate through alkalization, aging, yellowing and other processes, and then dissolved in dilute lye to make viscose. Made by spinning. Using different raw materials and spinning processes, ordinary viscose fibers, high wet modulus viscose fibers and high-strength viscose fibers can be obtained respectively. Viscose is favored by consumers because of its low price, soft touch, good air permeability and luster. [0003] At present, the number of units converting to process viscose in the printing and dyeing industry is increasing day by ...
