紧密赛络纺成纱疵品率的降低措施

摘要

以精梳棉27.8 tex甲配棉品种的纺制为例,探讨影响紧密赛络纺疵品率的因素.分析了吊锭间距不一致、粗纱更换不及时、网格圈周期性清洁不当及网格圈张力架弹簧失效因素对成纱疵品率的影响.研究表明,通过确保吊锭间距适当,及时更换粗纱,周期性清洁网格圈,对失效的网格圈张力架弹簧进行及时更换等措施,可有效降低紧密赛络纺成纱的疵品率.%The factors that affect the defect rate of JC 27.8 A were discussed.How the factors, such as the inconsistency of the spacing of spindles, the failure to replace the roving, the improper cleaning of the lattice apron,and the spring failure of the lattice frame influenced the defect rate were analyzed.The research showed that by ensuring appropriate distance between the spindles, replacement the roving timely, cleaning the lattice apron periodically, and replacement the failed grid ring dancer spring without delay, the defect rate of yarn could be reduced effectively.
