Problems solved by technology

It is reported that in the past dyeing process of knitted fabrics, the discharge of bleaching and dyeing wastewater is quite large, and the pollutants in the bleaching and dyeing wastewater are not environmentally friendly, and the pollution and waste of water resources are serious. At the same time, in order to obtain better dyeing effects, Add a variety of dyeing auxiliaries, the dyeing process is complicated, the operation is cumbersome, and the process cost is high
In addition, the color fastness and uniformity of dyeing are poor, which seriously affects the quality of knitted fabrics

Abstract

The invention discloses a dyeing process of a knitted fabric, and a dyeing machine. The dyeing process of the knitted fabric comprises pre-processing, dyeing, drying, colour fixation and shaping processes. According to the dyeing process of the knitted fabric in the invention, the knitted fabric is pre-processed through special pre-processing solution; the dispersity and the dyeing ability of a plant dye in the knitted fabric can be improved; the dyeing uniformity is ensured; the colour fastness and the dyeing efficiency can be increased; drying, colour fixation and thermal shaping are carriedout after dyeing; therefore, the colour fastness of the knitted fabric can be further improved; and thus, the texture is improved.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a dyeing process and a dyeing machine for knitted fabrics. Background technique [0002] With the development of the textile industry and changes in people's consumption concepts, people's life concepts have gradually shifted from material pursuits to spiritual pursuits. Compared with clothing, they are no longer satisfied with being strong and durable, but more about quality, Texture, comfort and enjoyment. [0003] Knitted fabrics are widely used in clothing and home textile fabric industries, and are deeply loved by consumers. It is reported that in the past dyeing process of knitted fabrics, the discharge of bleaching and dyeing wastewater is quite large, and the pollutants in the bleaching and dyeing wastewater are not environmentally friendly, and the pollution and waste of water resources are serious. At the same time, in order to obtain better dyeing effects, Ad...
