我厂有6台A453型粗纱机纺JT/C13＃纱,在1985年和1986年高温高湿季节,各用户厂提出布面纱疵过多影响出口。通过试验分析,主要是加压的马鞍架疲劳变形和三上四下曲线牵伸不合理;造成粗纱条干出现锯齿频数所致。这种锯齿纱对布面影响很大,特别是做纬纱织在布面上疵点明显。因此急需解决粗纱机牵伸问题。一、收集情报我们先后走访调查了一些兄弟纺织厂,查阅了大量的棉纺资料,最后确定A453型粗纱机必须首先解决须条的握持问题,其次解决稳定加压和得到
Our factory has 6 A453 roving machines for spinning JT/C13# yarns. In 1985 and 1986 high temperature and high humidity season, each user’s factory proposed that too many fabric veils affected the export. Through experimental analysis, it is mainly due to the fatigue deformation of the pressurized saddle frame and the unreasonable drafting of the three-up and four-down curves, which results in the occurrence of sawtooth frequency in the roving bar. This zigzag yarn has a great influence on the surface of the cloth, and in particular weaving the weft on the surface of the fabric is obvious. Therefore, it is urgent to solve the drafting problem of the roving frame. I. Collecting intelligence We visited several brothers’ textile mills and consulted a large number of cotton spinning materials. Finally, we determined that the A453 roving frame must first solve the gripping problem of the slivers, and then solve the problem of stable pressure and
