Influence of Roving Traverse for Condensed Spinning on Cotton Yarn Hairiness Fluctuation
摘要
Abstract
The influence of roving traverse for condensed spinning on cotton yarn hairiness fluctuation was discussed.EJM178 spinning frame was taken as an example.The necessity of roving traverse was described.The reason of the hairiness fluctuation brought by roving traverse of condensed spinning was analyzed.The calculation formula for wavelength was derived.Experiments were proceeded from four aspects including different yarn num-ber,with or without roving traverse,different traverse stroke and position offset of roving horn mouth.The hairi-ness fluctuation rule was reflected through hairiness spectrum and strip shadow in weft of fabric.The experiments show that the larger the yarn number,the hairiness fluctuation caused by roving traverse is more obvious.The hairiness fluctuation is intensified when the stroke for roving traverse is enlarged.The hairiness fluctuation is more obvious when the horn mouth position for roving is shifted.It is considered that the hairiness fluctuation of cotton yarn can be effectively improved by scientifically controlling the roving traverse of condensed spinning.关键词
