| Abstract: | The sea-island bicomponent superfine staple fiber with linear density of 3.5-4.4 dtex was produced by using CO-PET chip and PA6 chip on an imported spinning machine. The key technological process was discussed and optimized as followed:COPET pre-crystallization temperature 100 - 165℃ and time 18-23 min, drying temperature below 165℃ and time lower than 8 h, COPET-and-PA6 ratio 30:70, spin beam temperature 272-285℃, spinning velocity 800-1000 m/min, setting temperature 115-130℃. The produced bicomponent superfine staple fiber can satisfy the demand of afterprocessing. |
