Abstract

The invention relates to a gray fabric finishing process, and belongs to the technical field of textile manufacturing. The gray fabric finishing process includes the process steps: gray fabric singeing; washing; cold batching; washing; oxygen bleaching; dyeing; color fixing; washing; drying. Desizing and scouring enzyme additives are used in the cold batching process; scouring enzyme additives areused in the oxygen bleaching process; according to a color fixing process, after the Ph (potential of hydrogen) value of a dye bath is adjusted to be 5.6-6 by glacial acetic acid, color fixing agentsare removed from a full cotton gray fabric after color fixing, treatment temperature is controlled to be 111-115 DEG C, and treatment time is 30-40 minutes. The desizing and scouring enzyme additivesare prepared from, by weight, 3-5 parts of desizing enzyme, 10-15 parts of flax degumming enzyme, 0.5-2 parts of neutral cellulose, 10-15 parts of methyl methacrylate-chitosan composite materials, 3-5 parts of efficient penetrating agents and 63-68.5 parts of distilled water. The gray fabric finishing process is simple in preparation method, a prepared gray fabric is high in wear resistance, simple in technological process and low in production cost, and used raw materials are non-toxic, harmless, environmentally friendly and free from pollution.

Description

technical field [0001] The invention relates to a gray cloth finishing process, which belongs to the technical field of textile manufacturing. Background technique [0002] Gray cloth is natural color cotton cloth for printing and dyeing. Industrial gray cloth generally refers to cloth, or laminated gray cloth, glued gray cloth, etc. The traditional patchwork finishing process 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. Relatively wasteful, the consumption of steam, water and electricity is large, and the energy consumption is high. Chlorine bleaching is harmful to the human body and pollutes the air. [0003] Chitosan is made of chitin as raw material and then refined. It is insoluble in water, soluble in dilute acid, and can be absorbed by the human body. Chitosan is a primary derivative of chitin. Its chemical structure is a high-molecu...
