摘要: 文章针对某些塑料扁丝和碳纤织物纬纱不能变化捻度的需求,改变常规储纬器储纬的方式,探索了多种退绕方案,发现径向主动退绕效果为最佳,同时为了使纱线不交缠,利用光电信号反馈给输出马达,保持一定的储存量。结果表明:采用此装置可满足后续织造要求,纬纱保持原有形状不变捻度,布面质量达到了客户要求。

Abstract: To meet the requirement of changing the twist of weft yarn for some plastic flat yarn and carbon fiber fabric, transform the storage mode of conventional weft accumulator, this paper has explored a variety of unwinding plans, and found that the radial active unwinding effect was the optimal. In the meantime, in order to prevent the yarn from intertwining, the photoelectric signal was fed back to the output Marta to maintain a certain storage capacity. The results reveal that this device can meet the subsequent weaving requirements while maintaining the original shape of weft yarn without twist change. The fabric surface quality can also meet the customer requirements.

作者简介: 吴彤(1973),男,工程师,主要从事纺织机械、织造设备的调试与织造工艺参数的研究。
2008年中国塑料扁丝及其制品的产量约177.18万t,时至今日,其前景依然广阔[1]。2020年国际市场的碳纤维同比增长了3%,中国市场需求量在利好政策作用下强劲增长了29%[2]。随着以上两种材料的普遍运用,各个织造生产商都加大了对塑料扁丝织物及碳纤维织物的开发,以适应不断提高的客户需求[3],但当前的设备其产量及质量不能满足客户的需求。利用无梭织机织制塑料扁丝织物及碳纤维织物成为一种现实需求,但无梭织机必须配备储纬器,目前常规的储纬器类型都是在纬纱筒轴向引进纬纱,储存在纱鼓上,再从纱鼓轴向引出,这样在退绕和储存的过程中均会使纱线捻度发生变化,并对纬纱造成不同程度的摩擦扭曲。因为塑料扁丝横截面是长和宽差值较大的形态,碳纤维纱线不耐磨且抗剪切性能差,使用这两种原料织制的织物大多要求纬纱在织口内是平展无扭曲的,纬纱亦不能有损伤[4],故现有模式的储纬器无法满足织造需求。……
