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.

Development of Warp and Weft Slub Yarn High Density Double Cloth

To develop warp and weft slub yarn high density double cloth,preparation before weaving and weaving processing parameter were optimized. In warping process machine speed were reduced and tension were increased to re-duce slub yarn kinked. The same one size mixture formula and sizing box were adapted to sizing two kinds warp in sizing process so as to ensure sizing evenness. In heddle lifting warp with same movement rule were put into two contiguous heald frames to reduce slub yarn breakages. In weaving process in order to reach double cloth shedding clear demands, larger loom tension and earlier opening processing were adopted to reduce weft stoppage. Warp and weft stoppage could be reduced obviously and loom efficiency could reach above 90% through optimizing before weaving preparation and wea-ving et al processing parameters.
