摘要
粗纱伸长率是反映粗纱质量的一个综合指标,对粗纱质量影响很大,因此必须进行控制。通过对粗纱机张力参数进行优化,对卷绕工艺参数进行了调整。调整后有效控制了粗纱伸长及大、小纱的伸长差异率,提高了粗纱的条干和质量不匀率,降低了粗纱断头。
The stretch ratio of roving indicates roving quality and greatly affects roving quality and must be controUed. Through optimization of the tension parameters of roving frame and readjustment of the parameters in rewinding, roving stretch and stretch difference can be effectively controlled with roving sliver unevenness and roving quality improved and roving ends breakage reduced.
