Loop forming property of glass fiber during warp knitting

The glass fiber yarn is damaged easily during loop forming on warp knitting machine and difficult to produce fabrics.Thus,knitting experiments were carried out using glass fiber yarns with different specifications on different types of warp knitting machine.The influence of knitting device,let-off device,take-up device,yarn twist,direction of twist,and wetting agent on the knitting property of glass fiber was investigated.The torn selvage of fabric which is caused by yarn twist and direction of twist is analyzed,along with the key technologies for knitting glass fiber yarns.It′s proved that textile glass fiber yarns can be knitted successfully on tricot warp knitting machines with compound needle and positive let-off.
