摘要
以0.88 dtex细旦腈纶丝束为主要原料,在Seydel-679拉断机上生产细旦腈纶常规条,与3.33 dtex腈纶收缩条混纺,开发了仿羊绒腈纶的制条工艺。结果表明：拉断工序总拉伸倍数为6.05-6.27,再割区隔距比常规工艺大5 mm,卷曲箱压力略大,汽蒸压力为0.15-0.30 MPa;针梳工序常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1.15-1.30,梳箱喂入区牵伸倍数0.98,主牵伸倍数6~8,前罗拉隔距45 mm,适宜生产仿羊绒腈纶毛条。
Using 0.88 dtex fine denier acrylic tow as staple raw materials,the fine denier acrylic top was produced on a Seydel-679 stretch breaking machine, blended with 3.33 dtex acrylic shringking top, the slivering process was discussed and developed. The results showed that cashmere-like acrylic top can be produced suitablely, under the conditions of total stretch ratio 6.05--6.27, recutting separation distance is a bit too big, the steam pressure 0.15--0.30 MPa on stretch breaking working procedure, and the proportion of regular top and shrinking top 52：48, cutting down needles number, uncrimping zone stretch ration 1.15-- 1.30, comb box feeding zone stretch ration 0.98, main stretch ration 6--8, front roller distance 45 mm on gill box working procedure.
