| Abstract: | During the production of the 90 dtex/108 f porous fine denier polyester filaments with TCS,we should attach the importance to the process parameters ,such as moisture content of chips ,spinning temperature and speed,thermo-channel temperature and postion. The results showed that the good porous fine denier polyester filaments could be produced when moisture content of dried chips is less than 18 μg/g,the distance between the thermo-channel and spinneret is 920～960 mm, the thermo-channel temperature is 176～183 ℃,and the take-up speed is 4.2～4.4 km/min. |
