上机图设计对产品的影响

上机图设计对产品的生产和质量有很大影响。分析了毛巾织物穿筘设计、联合织物各组织分界线两旁组织点的设计、花式纱罗纬纱起始位置设计对产品的影响以及组织点的配置对色纱显色情况的影响。结果表明,地经纱与毛经纱排列比为1∶2的毛巾织物将地经纱夹在2根毛经纱中间穿入筘齿可以使毛经纱受到的摩擦阻力小;联合织物应尽可能使不同组织的边界左右配置与经纬组织点相反;当需织物正反面显示不同颜色时,正面纱线的长经浮线应能盖住相邻反面纱线的短经浮线;花式纱罗织物在生产时绞经纱在地经纱某一侧需要开口的次数多时,起始时该绞经纱就应该安排在地经纱这一侧。

Influence of looming draft design on products

The design of looming draft has great impact on both production and product quality.This paper analyzed the influence of designs of the reeding of towel,the interlacing points beside the dividing line on union fabric,and the beginning position of weft of leno brocade on products.The effect of design of the disposition of interlacing points on the development of colored yarn was also investigated.The result indicates that it will make the loop warp receive less frictional force to settle the basic warp between two loop warps and insert the warp through the dent while the ratio of basic warp to loop warp is 1∶2 in the towel;the different interlacing points should be set at two sides of dividing line as far as possible in the weave diagram of union fabric;when different colors are desired on back and face of the fabric,the long floats on the face should be able to cover the nearby short floats on the back in the weaving diagram;the crossing ends should be
