纤维的长度特征对成纱的影响

为探讨纤维长度对纺纱过程和成纱质量的影响,通过理论分析以及对一系列实验结果的分析和总结发现:在纺纱过程中,纤维长度不仅影响加工工序的选择,而且影响最终的成纱质量.由于纤维在纱条中呈随机排列,过长的纤维会导致成纱均匀度恶化,并对纺纱过程有负面作用；而太短的纤维会在一定程度上影响纱的强力.因此,选择长度适当的纤维可以兼顾纺纱和成纱综合质量.

Effect of fiber length on spinning and yarn quality

In order to discuss the effect of fiber length on both spinning process and quality of resultant yarn, this paper provides proper theoretical analysis combined with a series of experimental researches. The results show that the over long fiber length will impede the fiber arrangement in yarn and require long procedure of spinning, and the evenness of yarn and yarn strength decreased. On the other hand, short length of fiber is expected to affect the tenacity of yarn. Therefore, reasonable length of fiber is expected to benefit both for processing and quality of the yarn.
