经纬竹节高密双层织物的开发

为开发经纬竹节高密双层织物,对织前准备及织造工艺参数进行了优化。整经工序为减少竹节纱扭结,降低车速,加大张力垫圈质量;浆纱工序对两种经纱采用同一种浆料配方和同一个浆槽进行上浆,以保证上浆的均匀一致;穿综时将运动规律相同的经纱放到相邻两页综框上,以降低竹节纱的断头;织造工序为保证双层织物开清梭口的要求,采用较大上机张力,并采用早开口工艺以利于开清梭口、减少纬向停台。通过优化织前准备及织造等各工序的工艺参数,使经纬竹节高密双层织物的经向及纬向停台明显降低,织机效率达到90%以上。

Wet Permeability Characteristics of Double-layer Knitted Fabrics

In order to solve the problem that sweat flows back into the internal layer from the external layer in double-layer knits, a fabric structure model is set up and the conditions that keep the sweat from flowing back into the internal layer from the external layer are presented. It can be used to improve the design of the double-layer knits theoretically.
