细号棉氨纶弹力织物的生产

Production of Fine Cotton Spandex Elastic Fabric

总结细号棉氨纶弹力织物的生产要点。介绍了织物规格和经纬纱质量指标;整经车速适中,保证经纱排纱、张力、卷绕均匀;以变性淀粉TRF-S为主浆料,增强浆膜强力;采用“重渗透,求被覆,轻张力,小伸长”的浆纱工艺原则。加强设备状态维修和操作管理,保证浆轴质量。在ZA203-280型喷气织机上生产,优选引纬时间、喷气气压、停经架位置及开口量等。从纱线弹力不匀和织疵横档两方面分析了下机坯布质量问题。认为:严格控制各工序半制品的质量指标是保证产品顺利生产的关键。

Production key points of fine cotton spandex elastic fabric were summarized.Fabric specifications,warp arrangement and weft yarn quality indexes were introduced.Warping speed was moderate,warp arrangement,tension and winding were ensured uniform.Modified starch TRF-S was used as main size material to enhance sized film strength.Heavier penetration,coverage,lighter tension,smaller elongation was adopted as sizing process principle.Equipment state maintenance and operation management were strengthed to ensure quality of sizing beam.It was produced on ZA203-280 air-jet loom,weft insertion time,air jet pressure,stop warp frame position and shed amount were optimized.Quality problem of loom-state fabric was analyzed from aspects of yarn elastic unevenness and woven defects.It is considered that strict control of semi-products quality indicators in each process is the key to ensuring successful production.
