摘要: 针对玻璃纤维纱线在针织加工中不耐扭折、易受损断纱的现象,通过试验,分析了玻璃纤维纱线经编成圈的编织性能,探讨了整经工序中应注意的几个问题。在拉舍尔舌针经编机上编织了几种单梳和双梳织物,研究了玻璃纤维经编针织物的编织工艺。结果表明:玻璃纤维纱线在织针针头和导纱针针孔处的弯曲曲率和包围角越大,纱线越容易断裂;整经时应调整好工艺参数;成圈过程中,断纱最容易发生在套圈阶段,最好采用宽度较小的舌针;在保证顺利成圈的前提下,尽可能减小经纱送经张力;编织高密度织物时,织物表面起毛现象严重。

Abstract: In view of the phenomena that the glass fibre yarns break and damage easily due to brittleness of the yarns during knitting process,the warp knitting performances of glass fibre yarns are analyzed by experiments.Some precautions during warping processes are discussed.Several single bar and double bar fabrics are knitted on a Raschel latch needle warp knitting machine.The knitting technology of warp knitted glass fabrics is studied.The experimental results revealed that the larger the curvature and the wrap angle of glass fibre yarns bended at the hook of needle and the pinhole of guide bar needle,the easier the rupture of the yarns.The technological parameter adjustment is important during warping processes.In course of the stitch formation,the collapse of yarns occurs largely at the moment of landing.The needles hook with narrower width is preferred.In the precondition of stitch formation ensured smoothly,the tension of warping yarns ought to be decreased.The fabric surface is fuzzed when the fabric of high density is knitted.
