并纱是捻线的准备工序,其任务是将两根或多根(一般不超过5根)单纱并合后卷绕成筒子。经过并纱,可以保证单纱股数,均衡各单纱张力,减少股线捻不匀,提高股线强力,改善外观。
并通过与包缠纱织物和并捻纱织物的性能对比,得出差捻包缠纱织物的优势所在,指出差捻包缠纱织物在精纺领域应用是完全可行的。
By comparing with wrapped yarn fabric and doubling twist yarn fabric, the conclusion that the application of differential twist wrapped yarn fabric to worsted spinning is practicable was acquired.
并开发了一套以“纱模”为基础的计算机模拟显示系统。
A displaying system of computer simulation was developed based on the "yarn model".
兼顾成纱重量偏差和末并单机台重量偏差来调整末并牵伸齿轮,达到有效控制成纱百米重量偏差和重量CV %的目的。
Combining yarn weight deviation and drawing frame weight deviation to adjust wheel gear, valid control weight deviation per hundred meter yarn and weight CV % was achieved.
