摘要
研究以0．88dtex细特腈纶丝束为主要原料在Seydel-679型拉断机上生产细特腈纶正规条，并与3．33dtex腈纶收缩条混纺，开发生产仿羊绒腈纶条。结果表明，生产仿羊绒腈纶纤维条的适宜工艺为：拉断工序拉伸倍数6．05—6．27，再割区隔距比常规工艺大5mm，卷曲箱压力略大，汽蒸压力为0．15～0．3MPa；针梳工序正规条与收缩条配比为52：48，降低针板号数，退卷曲区牵伸倍数1．15～1．3，梳箱喂入区牵伸倍数0．98，主牵伸倍数6—8，前罗拉隔距45mm。
0.88dtex acryhc tow was used as main raw material and processed on Seydel -679 stretch breaking machine and blended with 3.33dtex shrinking acryhc top to develop cashmere - hke acrylic top. The result shows that cashmere - hke acrylic top can be produced based on the following parameters ： total stretch ratio in stretch breaking is 6.05 - 6.27, recutting gauge is 5mm bigger than normal process. Steam pressure is 0.15 - 0.3Mpa, proportion of regular top and shrinking top is 52：48 ,cutting down needle plate number,draft multiple in uncrimping zone is 1.15 - 1.3,draft multiple in comb box feeding zone is 0.98,main draft multiple is 6 - 8 and front roller gauge is 45mm.
