【摘要】 为利用双针床全成形电脑横机开发符合市场需求的产业用管状织物,以Y形三通管为例研究了全成形管状织物的成形方式与编织工艺的设计方法。利用全成形织针在满针筒形编织的同时进行前、后针床的移圈收放针,改变织物的横向宽度实现Y形三通管的全成形编织。通过将Y形三通管的三维结构转化为二维形状,根据尺寸、织物密度、编织方向与管间夹角等参数,设计与计算编织工艺。结果表明:Y形三通管织物管间夹角的大小由移圈收针时的编织收针比例决定,编织收针比例越大,管间夹角越大;采用不同的管径与织物密度实际编织2种角度的Y形三通管织物,验证计算公式的准确性与设计方法的可行性。更多还原

【Abstract】 In order to develop industrial tubular fabrics that meet market demand,a Y-shaped three-way tubular knitted fabric was engineered by using a computerized fully-fashioned double-needle-bed flat knitting machine,which was taken as an example to study the forming method of fully-fashioned tubular fabrics and the knitting process parameters. Fully-fashioned needles were used to narrow and widen the tubular fabric by transferring loops of the front and back needle beds while knitting the cylindrical shaped fabric. By changing the transverse width of the fabric,the Y-shaped three-way pipe can be knitted fullyfashioned. When designing, the three-dimensional structure of the Y-shaped three-way pipe was tranformed into a two-dimensional shape,and according to parameters such as size,fabric density,knitting direction and the angle between pipes,the knitting process was designed and calculated. The results show that the angle between the Y-shaped three-way fabric pipes is determined by the knitting-tonarrowing ratio. The larger the knitting-to-narrowing ratio,the greater the angle between the pipes. The accuracy of the calculation formula and the feasibility of the design method were verified by producing Yshaped three-way pipe fabrics with two different angles,employing different pipe diameters and fabric densities.更多还原
