"一线串三机"的异性纤维清除方案设计及应用研究OA

To improve the removal rate of foreign fibers in Xinjiang cotton and produce high-quality bleached yarns,the scheme of three foreign fiber cleaning machines in one production line was proposed,and compared with the scheme of two foreign fiber cleaning machines in one production line,including paper strip feeding test in foreign fiber cleaning machine,ejection times of foreign fiber,cutting defects of winding electronic yarn clearer and the number of foreign fiber defects per 100 000 m of yarns.The results showed that for the three foreign fiber cleaning machines in one production line scheme,the paper strip detection rate was higher,which reached 99.8%.The ejection times of foreign fiber cleaning machines remained within the standard range.The number of FD cut defects by the electronic yarn clearer was decreased from 71.7 to 43.0 per 100 000 m,and the PP cut defects per 100 000 m was decreased from 3.8 to 1.7.The number of foreign fiber in yarn defects per 100 000 m was reduced from 32 to 1.It is considered that the three foreign fiber cleaning machines in one production line configuration scheme can effectively enhance the removal rate of foreign fiber,thereby satisfying the production demand of high-quality bleached yarns.
