Embodiment 1

[0024] The invention provides a novel gray cloth finishing process, which includes the following process steps: gray cloth singeing→water washing→cold stacking→water washing→oxygen bleaching→dyeing→color fixation→water washing→drying; wherein the cold stacking process uses deboiling Enzyme auxiliary agent; the scouring enzyme auxiliary agent is used in the oxygen bleaching process, and the color fixing process is to use glacial acetic acid to adjust the pH value of the dyeing bath to 5.6-6, and then remove the fixed color of the cotton gray cloth after color fixing agent treatment, the treatment temperature is controlled at 111-115°C, and the treatment time is 30-40 minutes; the cold batch process refers to rolling the descaling enzyme additive at a controlled water temperature of 50-60°C, and the liquid rolling rate is 90-100% , two rolls and two dips, while the fabric is coiled and rotated on the A-frame, 8 rpm, and stacked at room temperature for 20-24 hours; the descouring ...

Abstract

The invention belongs to the technical field of textile manufacturing and relates to a novel gray fabric finishing process. The novel gray fabric finishing process is simple, prepared gray fabrics arehigh in environmental friendliness, a technical process is simple, low production cost is realized, and adopted raw materials are nontoxic, harmless and environmentally friendly and avoid pollution.

Description

technical field [0001] The invention relates to a novel 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-...
