摘要
本文分析了毛纺用载面为圆形、椭圆形、方形的三种梳针在梳理毛纤维时毛纤维的运动情况、受力情况,计算了毛纤维与梳针的摩擦角.分别对羊毛、山羊绒、安哥拉兔毛、牦牛毛与弹性针布钢针、金属针布针齿的摩擦角进行了测试.结果表明:毛纤维与梳针的摩擦角基本呈正态分布,但同类毛纤维的摩擦角随纤维直径变细而增大.
This article analyses the movement and stress of wool fibres when being carded by 3 kinds of needles: needles of round, oval and square cross-sections; calculates friction angles between wool fibres and needles. Tests for friction angles between wool, cashmere, Angora raaait hair, yak hair and pins of flexible clothing and teeth of MCC wire were made respectively. The results show that the frictional angles of wool fibres with carding needles substantially present in normal distribution, but the frictional angles of the same kind of wool fibre will increase with the decrease of fibre's diameter.
