When spinning short fibers, multiple strands are assembled together, and after being wetted and oiled, they fall into the silk barrel. Then the finished product is obtained through processes such as bundling, stretching, crimping, heat setting, and cutting. If stretched and heat-set at about 180 ℃ for one time, high-strength, low-elongation short fibers with a strength of more than 6cN/dtex and an elongation of less than 30% can be obtained. Polyester staple fiber is divided into cotton staple fiber (length 38mm) and wool staple fiber (length 56mm), which are used for blending with cotton fiber and wool respectively.
