细旦多孔PET-POY过尾成功率偏低的原因浅析

聚酯熔体在聚合过程中添加改性添加剂季戊四醇,形成共聚聚酯熔体,添加剂含量控制在(100～105)×106,纺丝无风区设置在60 mm,在欧瑞康EVO环吹装置上生产DIO 50D-75D/72F-192F规格POY产品,通过延长POY丝饼表层的吸丝时长,减少表层人为毛丝,控制合适的卷绕接触压力和产品贮存时间,缩小POY锭...

Cause analysis of low through-tail success rate of fine Denier Multi-hole PET-POY

The polyester melt is formed by adding the modified additive pentaerythritol in the polymerization process,the additive content is controlled between(100~105)×10⁶,and the spinning no-wind zone is set at 60 mm,the dio 50 D-75 D/72 F-192 F POY product was produced on the OC oerlikon evo ring blowing device,and the suitable winding contact pressure and product storage time were controlled by prolonging the suction time of the surface layer of the POY cake,reducing the artificial fuzz of the surface layer,to reduce the tension difference between the bottom layer and the surface layer of the filament bundle of pet POY,to strengthen the sampling and selection before the paper tube is put on the machine,to reduce the on-line tension of the texturing process,and to improve the over-end success rate of PET-POY from 90%to over 97%,at the same time,the physical performance,color absorption and fabric style of PET-DTY products are significantly improved compared with ordinary PET-DTY products.
