Problems solved by technology

In addition, the fabric dyeing and finishing process is accompanied by the consumption of water resources and the generation of a large amount of wastewater. The treatment cost of these wastewater is very high. If it is discharged directly without treatment, it will cause serious pollution to the ecological environment, especially rivers and groundwater resources.

Abstract

The invention provides a water-saving and emission-reducing dyeing and finishing technology for a fabric. The technology comprises the following steps: 1, carrying out plasma treatment: carrying out etching modification treatment on a fabric to be dyed by a plasma treatment device; 2, desizing and bleaching: adding a desizing enzyme, a chelated dispersant, a wax remover and a scouring agent to thefabric, performing desizing treatment, adding hydrogen peroxide, sodium silicate, the scouring agent and a chelating agent, and performing bleaching treatment; 3, performing cellulase treatment: adding cellulase to the bleached fabric, and carrying out enzyme treatment; 4, pre-setting: carrying out hot wind heating pre-setting by a pin tenter; 5, dyeing: adding water according to a bath ratio of1:(1-2), sequentially adding a leveling agent, a reactive dye, anhydrous sodium sulfate and acetic acid to adjust the pH value of the obtained solution to 4-6, heating the solution to 60 DEG C according to a rate of 1 DEG C / min, carrying out heat insulation treatment for 15-60 min, cooling the obtained solution to 50 DEG C according to a rate of 1 DEG C / min, washing the obtained fabric with water,and discharging water; 6, carrying out resin finishing; and 7, setting the fabric.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a fabric water-saving and emission-reducing dyeing and finishing process. Background technique [0002] Dyeing and finishing is a technological process mainly based on chemical treatment of textile materials, and the quality of dyeing and finishing has an important impact on the use value of textiles. In addition, the fabric dyeing and finishing process is accompanied by the consumption of water resources and the generation of a large amount of wastewater. The treatment cost of these wastewater is very high. If it is discharged directly without treatment, it will cause serious pollution to the ecological environment, especially rivers and groundwater resources. [0003] Therefore, it is necessary to propose a dyeing and finishing process that can enhance the fastness of dyeing and finishing, make the fabric dyeing more uniform, improve the dyeing q...
