Problems solved by technology

[0003] The present invention mainly solves the deficiencies existing in the prior art, and solves the deficiencies existing in the existing knit fabric overflow intermittent pretreatment technology. This method makes the cotton type The scouring and bleaching of knitted fabrics can get rid of the constraints of the traditional intermittent processing method and be separated from the dyeing vat. The treatment effect is stable and excellent. The continuous, standardized and professional production process realizes high reproducibility, high success rate and high smoothness of dyeing. It can effectively improve the dyeing production capacity, realize the energy saving and emission reduction in the pretreatment and dyeing stages, and solve the problems of long time, high energy consumption and high production cost of existing processing methods.

Embodiment 1

[0029] Embodiment 1: A kind of open-width continuous pre-treatment cleaning production process method is carried out according to the following steps:

[0030] (1) Selection of degreasing and bleaching liquid additives and formula design:

[0031] Degreasing pretreatment is a very important first step to improve the water absorption and whiteness of the knitted gray fabric; through degreasing, the spinning oil and impurities on the gray fabric will be completely washed away; after prewashing, the fabric will be impregnated with scouring agent and Bleach, then steamed in a special steam box for knitwear, and then washed continuously, finally neutralized, rinsed, and discharged from the machine;

[0032] Preparation method of degreasing liquid: add 40% normal temperature water into the chemical tank, add degreasing liquid, stir and dissolve for 15 minutes, then add 30% water, continue stirring until uniform;

[0033] The preparation method of refining agent bleaching solution: ...

Abstract

The invention discloses a technique method, and especially relates to a technique of full width continuous pretreatment cleaning production of knitted fabrics. The technique is carried out according to steps of use of degreaser and bleaching liquid assistant and formula design-design of very technical parameter of full width continuous pretreatment-intelligent control production of full width continuous pretreatment-dyeing of gas-liquid dyeing machine-post finishing-finished product inspection. A technique of full width continuous pretreatment cleaning production of knitted fabrics can replacean overflow dyeing machine and its similar wet processing technique method, and has obvious effects of energy-saving and emission reduction; the technique has the advantages of improving the production efficiency, reducing resource, energy source, materials and human resources while improving the quality of the of knitted and dyed product and the product grade, further promoting the market competitiveness of enterprises and products, and creating preconditions. Moreover, the technique solves the problems widely concerned by the industry that the production efficiency of the existing wet treatment techniques and technical equipment for bleaching, dyeing, washing knitted fabrics is low; consumptions of resource, energy source, material and human source are huge; the emission amount of bleaching and dyeing waste water and pollutants is big.

Description

technical field [0001] The invention relates to a process method, in particular to a clean production process method for continuous pretreatment of knitted fabrics. Background technique [0002] It is an indisputable fact that the existing knitted fabric bleaching, dyeing, washing and other wet treatment processes and process equipment have low production efficiency; large consumption of resources, energy, materials, and manpower; large amount of bleaching and dyeing wastewater and pollutant discharge. Has aroused widespread concern in the industry. Today, when energy saving and emission reduction have become the basic national policy of our country, and the printing and dyeing industry vigorously promotes clean production, the implementation of the current intermittent and rope-like knitted fabric bleaching and dyeing process and process equipment and the industrial policy of "energy saving and emission reduction", as well as the implementation of clean production work The...
