喷气织机织造小提花织物的难点及解决办法

Difficulty and Solving Method of Weaving Mini-jacquard Fabric in Air-jet Loom

探讨在喷气织机上生产小提花织物的织造工艺设置。穿综时要把花形组织点最少或头份最少的经纱穿入最后排的综框,花形组织点最多或头份最多的经纱穿入最前排的综框;穿筘时要注意总结方法,及时纠错;在织造工序采用半清晰梭口,合理设置经位置线和引纬工艺。通过实例分析说明,造成布面风格较差的主要原因是前后综框上经纱张力差异较大,调整综框高度后可改善布面风格,织机效率从85%提高到90%。

Weaving processing of producing mini-jacquard fabric in air-jet loom was discussed. In heddle draft the least pattern weave repetition warp or the least warp number in beam warp should be threaded in last heald, the most pattern weave repetition warp or the most warp number in beam warp should be threaded in first heald. Method should be summaried in reeding and mistake should be rectified in time, In weaving process semi-clean shed was adopted, warp shed line and weft inserting processing were set propery, Through example analyses and introductions, the main reason that cause fabric style worse is great warp tension difference of front and back heald. Fabric style could be improved after adjusting heald weight and loom efficiency could be improved from 85% to 90%.
