Problems solved by technology

This process mainly uses water washing, twice alkali boiling, once chlorine bleaching, and once oxygen bleaching. The wetting agent and chelating agent used in oxygen bleaching can be dissolved and removed, but the fiber stripping is more difficult, especially the strength of viscose fiber is reduced
Moreover, the traditional treatment method also uses a large amount of alkali and surfactant, resulting in high cost, large sewage discharge, high BOD and COD in water, high treatment cost and increased environmental burden, and the second is complicated process, labor and time. Relatively wasteful, large consumption of steam, water and electricity, high energy consumption

Abstract

The invention discloses a preprocessing technical method of cotton linen and linen rayon gray fabrics, comprising the steps of gray fabric singeing, rinsing, cold batching, rinsing, oxygen bleaching, rinsing and drying, wherein the cold batching process adopts a desizing enzyme auxiliary agent and the oxygen bleaching process adopts a scouring enzyme auxiliary agent. The products processed by the invention has the characteristics of soft feel, clean desizing, small strength loss, good whiteness and favorable capillary effect, and the production process has the advantages of safety, environment protection, low cost, small energy consumption and high production efficiency.

Description

technical field [0001] The invention relates to a pretreatment process for cotton flax and sticky flax gray cloth. Background technique [0002] The traditional pretreatment process of cotton flax and viscose flax gray cloth often includes the following process steps: gray cloth singeing and desizing → water washing → 100°C alkali boiling for 60 minutes → hot water washing at 70-90°C for three compartments, cold washing for one compartment → 100°C alkali boiling 60min→hot water wash 70-90℃ three compartments, cold wash one compartment→chlorine bleaching→neutralization water washing→oxygen bleaching 100℃, 60min hot water washing 70-90℃ three compartments, cold washing one compartment→drying. This process mainly uses water washing, twice alkali boiling, once chlorine bleaching, and once oxygen bleaching. The wetting agent and chelating agent used in oxygen bleaching can be dissolved and removed, but the fiber stripping is more difficult, especially the strength of viscose fib...
