吸湿排汗抗起毛抗起球纤维/PTT/羊毛针织混纺纱生产实践

Production practice of knitted yarn with wicking anti-pilling fiber /PTT /wool

介绍14.8 tex吸湿排汗抗起毛抗起球纤维/PTT/羊毛65/20/15针织混纺纱的原料性能特点,探讨纺纱各工序关键技术要点和生产工艺参数配置。根据原料性能特点,结合工厂实际情况选择合理的纺纱工艺路线,做好原料纺前预处理,开清工序要多开松少落棉,梳棉工序采用紧隔距,加强梳理,并条做到合理配置前后区牵伸倍数,粗纱选择合适的捻系数,细纱采取降低车速加强纤维控制提高纱线条干。只有合理的配置工艺参数,采取恰当的技术措施,才能保证纱线的顺利生产并达到设计的质量要求。

The paper describes the properties of raw material used in 14. 8 tex knitted yarn with wicking anti-pilling fiber/PTT/wool （65/20/15）, the key technical points of each process and parameters were also disscussed. According to the characteristics of raw performance, combining with practical situations, a spinning process route was selected rationally, raw material was pretreated before spinning, more opening,less noil should be adopted in opening and cleaning process, tight gauge, strong carding were introduced in carding process, rational distribution of drafting was chosen in drawing process, suitable roving twist factor was chosen, low speed and strengthening fiber controlling should be adopted to improve yarn evenness. Only by appropriate process parameters as well as adopting appropriate technical, smooth production of yarn can be ensured and achieve the design requirement.
