摘要
探索了环吹风冷却法生产单丝直径0．05—0．08mmPBT毛刷丝的工艺技术，研究了与之相对应的纺丝工艺条件。研究结果表明，当采用90孔喷丝板，卷绕速度600m／min，生产单丝直径0．06mm（相当于48dtex）的PBT刷用丝时，环吹风速为0．3～0．5m／s，环吹风温为15～20℃，环吹风湿度为60％-70％。为加强丝条的冷却速率，采用增加雾化冷却装置的方法来提高冷却介质的传热效率。
Researched the processes of brush fiber production by circular blow cooling method, the corresponding spinning conditions were also discussed. Results show that, when product 0. 06 mm （ 48dtex ） PBT brush fiber in 90 hole spinneret and 600 m/min winding speed, the corresponding air cooling conditions are wind speed 0. 3 - 0. 5 m/s, wind temperature 15 - 20 ℃, wind relative humidity 60 70%. To enhance the cooling rate, water atomization cooling device can be used to increase the cooling media＇s heat transfer efficiency.
