Technical field:
[0001] The invention relates to a production method of polyester colored staple fibers. It belongs to the technical field of chemical fiber. Background technique:
[0002] Polyester (respun) colored staple fibers are widely used in various fields such as textiles, carpets, and clothing fabrics. The traditional production method of polyester colored staple fiber is to adopt polyester polyester raw material to be dyed after spinning first. Due to the relatively tight molecular structure and high crystallinity of polyester, it is difficult to dye, and the dyeing process is complicated, the pollution is serious, the cost is high, the color difference of the product is large, the color fastness is poor, and it is easy to fade. Invention content:
[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a production method of polyester colored staple fibers with simple process, low cost, less pollution, small p...
