异经异纬卡其织物的生产实践

Experience of Producing Different Warp and Weft Khaki Fabric

探讨异经异纬卡其织物的生产工艺和关键技术措施。通过分析织物的原料性能、产品规格、布面风格,并线时要提高并线筒纱张力的一致性;在浆纱工序异经同浆时要采取"高预烘,低主烘"的工艺配置,经轴在退绕时两种经纱重叠区用布隔离,防止断头经纱混入另一种经纱里造成错号;在织造工序采用"小开口,中后梁,早开口,大张力"工艺配置,合理配置经位置线和引纬气压,可确保该系列织物的织机效率达92%以上,出口合格率达98%以上。

Production processing and key technology measures of using different warp and weft khaki fabric were discussed. Through analyzing the material porperty, product specifications, fabric style, the cheese tension uniformity should be improved in doubling, high predrying temperature and low maindrying temperature should be adopted in different warps sizing, the overlap between two kinds of warp should be insulated by fabric in beam unwinding to prevent warp mixed into another warp, the processing of smaller shedding, suitable back-bearer height, earlier shedding and greater tension should be set in weaving, warp shed line and picking pressure should be set suitably, the loom efficiency of weaving different warp and weft khaki fabric can be ensured over 92% , the export qualification rate can be reached over 98%
