Abstract

The present invention relates to chemical fiber and its the production of short colored polyester staple. The present invention features that color agglomerate is added into polyester material before direct spinning to color yarn. Without passing through dyeing, the said production process is simple, low in cost, less pollution, less color difference, and color fast, and the product has wide color spectrum and bright color.

Description

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...
