Problems solved by technology

However, the dyeing and finishing process of traditional dyed fabrics is relatively long, and the fabrics need to be scoured during the dyeing and finishing process. Scouring requires the use of a large amount of sodium hydroxide, which is highly corrosive and harmful to the environment. In addition to processing and scouring, fabrics need to be dyed, a large amount of waste water is produced in the dyeing process, and the energy consumption in the dyeing process is large, which causes great environmental pollution. These problems seriously hinder the further development of the textile industry.

Abstract

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a short-flow processing technology for a dope-dyed fabric. The method comprises the following steps: singeing, desizing and tentering a dope-dyed fabric to obtain a dope-dyed fabric; a feed liquid used in the pretreatment desizing procedure is prepared from 6-8 g / l of desizing enzyme OPT-280, 1-5 g / l of chelating agent and 6-8 g / l of penetrant. And a feed liquid used in the after-finishing tentering process is formed by mixing a modified polysiloxane softening agent TF-4865C and a polyethylene polyamine color fixing agent GD-80. The fabric is soft in hand feeling and excellent in color fastness, the invention further provides a processing technology of the fabric, processing, desizing, scouring and dyeing are not needed in the dyeing and finishing process, the fabric is diversified in color and bright in finishing mode, the technological process is short, discharge of printing and dyeing wastewater is greatly reduced, and the fabric conforms to the green and environment-friendly development concept at the present stage.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a short-process processing technology for dope dyed fabrics. Background technique [0002] With the development of society and the continuous improvement of living standards, consumers have not only improved the wearing comfort of fabrics, but also put forward higher requirements for the environmental protection performance of fabrics. However, the dyeing and finishing process of traditional dyed fabrics is relatively long, and the fabrics need to be scoured during the dyeing and finishing process. Scouring requires the use of a large amount of sodium hydroxide, which is highly corrosive and harmful to the environment. In addition to processing and scouring, fabrics need to be dyed, a large amount of waste water is generated in the dyeing process, and the energy consumption in the dyeing process is large, and the environmental pollution is relative...
