Problems solved by technology

However, at this stage, most of the dope-dyed fibers are regenerated cellulose fibers such as polyester / viscose and bamboo polyester. This fabric is prone to poor pilling resistance during processing, which affects wearing performance.
[0003] At present, most of the attention in the industry is on the processing method of dope dyeing, and no patent or literature has been found to improve the anti-pilling of fabric dope dyeing

Abstract

The invention relates to a continuous processing technology for improving fuzzing and pilling of a dope-dyed fabric, and belongs to the technical field of textile printing and dyeing. The continuous processing technology for improving fuzzing and pilling of the dope-dyed fabric adopts the following processing flow: singeing, cold batching, washing, tentering and preshrinking, and self-crosslinking polyether polyurethane and a silicon softening agent are adopted in the tentering process. By adopting the process disclosed by the invention, the fuzzing and pilling of the dope-dyed fabric are improved from 2.5 level to 3.5 level, and the improved process is green and environment-friendly; by optimizing the dyeing and finishing process flow and process parameters, the produced dope-dyed fabric has excellent anti-pilling ability and soft hand feeling.

Description

technical field [0001] The invention relates to a continuous processing technology for improving the pilling of dope dyed fabrics, belonging to the technical field of textile printing and dyeing. Background technique [0002] Dope dyed fiber is also called color spinning fiber, pre-spun dyed fiber, which is a fiber made by adding color masterbatch during polymerization or spinning in the production of chemical fiber. Various colors, therefore, the printing and dyeing process is omitted in the downstream production process, which greatly improves the degree of "green" of the obtained textiles, and has outstanding environmental friendly features. However, at this stage, most of the dope-dyed fibers are regenerated cellulose fibers such as polyester / viscose and bamboo polyester. This fabric is prone to poor anti-pilling ability during processing, which affects the wearing performance. [0003] At present, most of the attention in the industry is on the processing method of dop...
