| Abstract: | The 6.67 dtex polyester hollow staple fiber was produced on the conventional production line withspecial designed hollow spinnerette, proper modified quenching system and bailing press and adding spe-cial thermosetting equipment. The production process of the fiber was discussed. The results showed thatthe 6.67 dtex hollow staple fiber with hollowness degree of 30 %~35 % was produced at the conditions ofspinning temperature 286~288 ℃, quenching temperature 19~21 ℃ and air velocity 3.4~3.5 m/s, draw ratio3.0 and drawing temperature 85~90 ℃. The quality index of the finished product was up to the require-ments of down stream customers. |
