Problems solved by technology

However, during the whole post-treatment process, its temperature is above 75°C, which makes its demand for heat energy high, resulting in high energy consumption. In addition, the traditional dyeing post-treatment process requires multiple washing processes, resulting in its It takes a lot of energy, water and time, which not only seriously affects the production efficiency of the bleaching and dyeing factory, but also produces a lot of sewage

Abstract

The invention discloses an environment-friendly, energy-saving and water-saving process for all-cotton and polyester-cotton fabric. The process comprises steps as follows: a dyeing solution in a dyeing jar is discharged, and meanwhile, dyed fabric is taken out and put in a container; cold water is added to the container for cold water washing, and the water is drained after 10-20 min; hot water isadded to the container for hot water washing, and the water is drained after 20-30 min; a soaping solution is added to the container, heated and kept at the constant temperature for 15-25 min, and then, the soaping solution is drained; a little acid is added to the container for acid and alkaline neutralization, so that the fabric is located under the acid condition; the hot water is added to thecontainer for hot water washing, the water is drained after 20-30 min, and an aftertreatment process is completed. The process has the benefits as follows: the washing frequency is reduced, the temperature demand of high-temperature soaping is also avoided, consumption of water resources, energy and time is effectively reduced, and the production efficiency of a bleaching and dyeing house is effectively and further improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an environmentally friendly, energy-saving and water-saving process for after-treatment of all-cotton polyester-cotton fabrics. Background technique [0002] Cotton fabric is a natural cellulose fiber, which is widely loved by consumers. In order to meet the needs of different consumers for color, it needs to be dyed during production. At present, reactive dyes are mainly used for dyeing cotton fabrics. Reactive dyes have the advantages of complete color spectrum and bright color, but reactive dyes are easy to hydrolyze, and there are dyes that are partially hydrolyzed and not combined with fibers on the dyed products. It is easy to fall off during the washing process, which affects the color fastness and the brightness of the color, especially the color fastness to washing. In order to improve the color fastness to washing of dyed goods, post-dyeing treatment must be carried o...
