Influence of Slub Permutation and Combination for Rotor Spun Slub Yarn on Slub Effect

探讨转杯纱竹节排列组合对竹节效果的影响。转杯纺纺制短竹节纱时,实际节粗小于设计节粗,竹节效果不明显。先后尝试直接增加设计节粗和两种竹节排列结合两种方式,增加实测节粗。但是直接增加设计节粗的方式会导致纺制困难,竹节风格无法保证,相比两种竹节排列结合的方式实测节粗增加明显,竹节风格较好。认为:转杯纺竹节纱实际纺制过程中,宜采用两种竹节排列组合的方式增加实测节粗。

The influence of slub permutation and combination for rotor slub yarn on sluh effect was dis- cussed. When rotor spinning was used for short slub yarn spinning, the practical slub muhiple was smaller than designed slub muhiple. The slub effect was not obvious. Two methods including direct increasing designed slub nmhiple and two slub permutation and combination were tried one after another to increase the practical slub mul- tiple. However.the spinning was difficult with the method of direct increasing designed slub muhiple and the slub style could not be guaranteed. By the comparison,with the method of two slub permutation and combination,the practical sluh muhiple was increased obviously and the slub style was better. It is considered that the method of two sluh permutation and comhination should be adopted to increase practical slub multiple during the practical spinning of rotor slub yarn.
