竹节纱竹节参数与捻度分布的关系研究

Research on the relationship between slub parameter and twist distribution of slub yarn

探讨竹节纱的捻度分布规律。以竹节纱的设计捻度、节长、节距和节粗为研究对象,分别研究了它们在设定范围内的变化对竹节纱竹节部分捻度和基纱部分捻度的影响,并分别构建了竹节、基纱部分捻度和这4个因素的多元线性关系拟合模型。通过实际生产工艺纺制竹节纱,对竹节、基纱部分捻度的拟合模型进行了验证。结果表明:在所设计的竹节参数范围内,竹节纱竹节部分捻度和基纱部分捻度的拟合准确率分别达到了96.73%和97.99%。

The twist distribution law of slub yarn was discussed.The design twist,slub length,slub distance and slub multiple were taken as the research objects.The relationships between the variation of these slub parameters in the set range and the twist of slub part and base yarn part were studied.Multiple linear relationship fitting model of twist of slub and base yarn with the four factors were constructed respectively.The slub yarn was spun by practical production technology,the fitting model of twist of slub and base yarn was verified.The results showed that within the range of the designed parameters,the fitting accuracy of the twist of the slub yarn and the twist of the base yarn can be reached 96.73%and 97.99%respectively.
