Abstract: 针对传统低捻纱强度低,影响其应用的问题,在环锭细纱机前罗拉和导纱钩之间安装1个专门设计的假捻装置,增加纺纱三角区内纤维的转移和纱线纤维间的抱合力,使纱线在具有较低捻度的同时拥有较高的强度。检测纱线的内部和外部结构,对比改良纱、普通捻度环锭纱和低捻度环锭纱的截面内纤维分布规律、纱线内的纤维轨迹以及纱线的表面结构。实验结果表明,经过改进的低捻度环锭纱与普通环锭纱具有不同的结构。
For solving the problems of conventional low twist yarns due to their low tenacity,a specially designed false twister was installed between the front rollers and yarn guide on a conventional ring spinning frame for increasing fiber migration and entanglement in the spinning triangle,leading to a reinforcement of yarn strength.Thus the produced yarn has a low twist and a relatively high strength simultaneously.In addition,the yarn internal and external structures were examined and the radial fiber distribution,fiber path and yarn surface structure between the modified,normal and low twist conventional ring yarns were compared.The results reveal that the modified low twist yarn has a structure different from the conventional ring spun yarns.
