双针床超大隔距经编间隔织物生产实践

Production Process of Large Interval Double Needle Bar Warp Knitted Spacer Products

根据双针床超大隔距经编间隔织物的特点,对超大隔距双针床经编机的成圈机构、送经机构和牵拉机构等主要机构的结构与工作要求进行分析,特别是对间隔梳的摆动动程进行探讨。设计一种隔距为100 mm的超大隔距经编间隔织物,详细介绍原料选择、组织结构设计等编织工艺和水洗、压延等后整理工艺。超大隔距经编间隔织物耐候性强、使用寿命长、尺寸稳定性好、抗拉强度高、充气后应力分布均匀,应用前景良好。

According to the characteristics of large interval double needle bar warp knitted fabrics,this paper analyzed mechanical structures and working requirements of the looping mechanism,let-off mechanism and draw-off mechanism of the large interval double needle bar warp knitting machine.In particular,the swinging motion of the spacer guide-bar was discussed.A kind of large interval double needle bar warp knitted fabric with the interval of 100 mm was design.The knitting process,such as material selection,structure design,and finishing process such as water washing and calendering were introduced in detail.The large interval warp knitted fabric has strong weatherability,long service life,good dimensional stability,high tensile strength and uniform stress distribution after inflation,which has broad application prospects.
