化纤长丝的内应力及内应力的均匀性,是两个重要指标。内应力大小反映长丝的强度,均匀性反映长丝的质量。内应力及其均匀性是通过连续检测长丝的张力大小和变化情况来得到的。研究化纤长丝与圆柱固体的摩擦是为了控制导纱过程中的张力,化纤长丝在编织过程中,极易造成张力不匀。因此要控制化纤的张力,就必须进行摩擦性能的
The internal stress of chemical fiber filament and the uniformity of internal stress are two important indexes. The size of the internal stress reflects the strength of the filament, the uniformity reflects the quality of the filament. The internal stress and its uniformity are measured by continuously measuring the tension of the filaments and their variation. Study of chemical fiber filament and cylindrical solid friction is to control the tension during yarn guide, chemical fiber filament in the weaving process, can easily lead to uneven tension. Therefore, to control the tension of chemical fiber, it must be frictional properties
