Continuous color knitted jean fabric pad dyeing process

Abstract

The invention relates to a continuous color knitted jean fabric pad dyeing process. The process comprises the following working procedures of cloth knitting, singeing, scouring and bleaching, dyeing, combining and finishing, and finished cloth obtaining. An open-width open fire singeing method is adopted in the working procedure of singeing. A continuous open-width scouring and bleaching method is adopted in the working procedure of scouring and bleaching, and countercurrent flushing is carried out through under-liquid soaking and up-liquid spraying by means of a drum; the rolling and drying process is adopted for dyeing in the working procedure of dyeing, an evenness calender is used for padding dye on cloth, and a steam drying cylinder is utilized for drying the cloth. According to the process, in the whole process, the open-width continuous production process is adopted, the production working procedures are reduced or combined, the problem that sulfur dyestuff color series can not be used for needle dyeing and cloth knitting of a rope-like dyeing machine for many years is solved, and the low-emission and low-energy-consumption continuous color knitted jean fabric pad dyeing process is achieved.

Description

technical field [0001] The invention relates to a continuous color knitted denim fabric pad dyeing process. Background technique [0002] In the printing and dyeing industry of knitted fabrics, traditional knitted fabrics usually adopt rope dyeing process, the steps include: boiling and bleaching, cleaning, hair removal, rinsing, dip dyeing, rinsing, soaping, rinsing, color fixing, softening and shaping, etc. This kind of rope dyeing process has disadvantages such as complex dyeing process, long process time, low production efficiency, low dyeing rate, and large amount of polluted waste water, which brings a great burden to environmental governance. Textile dyeing factories have also become environmental protection in some areas. The key targets targeted by the department have restricted the comprehensive competitiveness of our country's textile and garment industry to a certain extent. [0003] On the other hand, the rope dyeing machine is only suitable for dyeing sulfur b...

Problems solved by technology

The products woven by these methods are rich in color and meet people's needs, but the process method is still limited to yarn dyeing, the process is long, the process is complicated, and it is not suitable for industrialized mass production.

In addition, after yarn dyeing and blending, the fabric still has the problem of color difference, the product quality is unstable, and it is not suitable for batch continuous production
