Pre-treatment process of textile fabric

Abstract

The invention relates to a pre-treatment process of a textile fabric. The pre-treatment process comprises: a step of clear water boiling, a step of biological agent immersion, and a step of pre-treatment of dyeing in an overflow tank. The step of biological agent immersion comprises: adding a biological agent, citric acid, and glucose into the textile fabric; adjusting the pH value to 4.5-5.0; and immersing the textile fabric at a constant temperature in a range of 35-39 DEG C for 8-12 days, wherein the biological agent is a plant ferment consisting of brown sugar, fruits, and water. A preparation method of the plant ferment includes fermenting brown sugar, fruits, and water in the absence of light for 2.5-3.5 months in a sealed environment. Since the biological agent is added, pectin and lignin in linen fiber can be effectively decomposed. Compared with a traditional process, the pre-treatment process is saved in water, power, and gas. Discharge of waste water is greatly reduced due to no addition of a printing and dyeing auxiliary, thereby satisfying the requirement of environment protection and energy saving.

Description

technical field [0001] The invention relates to a pretreatment process of textile fabrics, belonging to the technical field of printing and dyeing processes. Background technique [0002] my country is a big textile country. In the traditional textile printing and dyeing industry, the printing and dyeing process will cause a certain degree of pollution to the environment. In recent years, my country has encouraged and focused on the development of new energy sources including biomass energy, combined with ecological engineering technology, vigorously developed clean projects, adopted diversified paths, and strived to realize the promise of emission reduction within a period of time, and make due contributions to human beings. contribution. [0003] At present, the pre-treatment process of linen fabrics is as follows: cloth turning - sewing - singeing - alkali scouring - washing - chlorine bleaching - washing - oxygen bleaching - washing - drying - tentering - mercerizing - l...

AI Technical Summary

Problems solved by technology

[0005] 1. Pretreatment consumes water and energy during smelting, chlorine bleaching, and oxygen bleaching, and discharges more waste gas and waste water, causing a certain degree of environmental pollution

[0006] 2. Sodium hypochlorite has a destructive effect on the fiber polymerization degree during chlorine bleaching, which directly causes the breakage of the cellulose macromolecular chain, that is, the reduction of the fiber polymerization degree

[0007] 3. The entire pre-treatment process is carried out under tension conditions. The fabric is stretched to make it stiff and hardened. It can only be tie-dyeed in a long machine. The shrinkage of the finished product is generally 8-10. The garment or fabric must be washed before use.
