摘　　要：松紧档疵点是喷水织机长丝织物织造过程中常见的纬向织疵之一,其严重破坏坯布外观,影响坯布手感,降低坯布质量。简述了在生产织造过程中松紧档疵点的形态分布,综述了国内外对松紧档疵点成因的研究概况,指出了松紧档疵点的产生与打纬、送经及卷取机构零部件的磨损和失效密切相关。从机械调整与维护、原料及生产过程管理、工艺参数优化等方面入手,提出了减少松紧档疵点的对策。Elastic file defect is one of the common weft defects in filament fabric weaving process of water jet loom. It severely damages the appearance of the fabric, affects the fabric handle, and reduces the quality of fabric. The morphological distribution of elastic file defects is introduced. The research on the causes of elastic file defect both at home and abroad is reviewed, elastic file defect is closely related to the abrasion of parts and components in beating up, let-off and take-up mechanisms are pointed out. The countermeasures about mechanical adjustment and maintenance, materials, production process management and process optimization and other aspects are proposed to reduce the production of elastic file defect.
