| 摘 要： | 自捻纱由交替的 Z 捻段和 S 捻段以及无捻区段 3 个区段组成.对比观察自捻纱和相同支数环锭单纱和股线的纵截面,结果显示:自捻纱 Z 捻段和 S 捻段的纵截面特征和环锭股线近似.自捻纱的无捻区由分离的 2 根须条组成,是影响纱线性能的关键区段.纺制 2 种纺纱线密度,5 种纺纱速度自捻纱,测量其 Z 捻段和 S 捻段自捻捻度及无捻区长度,结果表明:自捻纱的 Z 捻段和 S 捻段的自捻捻度随纺纱速度增加而下降.在周期长度和自捻罗拉往复动程固定的前提下,自捻捻度不仅和纺纱线密度有关,还与纺纱速度有关.自捻纱无捻区长度随着纺纱速度的增加而增加.纺纱线密度越低,无捻区长度越大. |

| Abstract: | Self-twist yarn consists of three zones: Z-twist zone,S-twist zone and no twist zone.By comparison longitudinal shape of self-twist yarn with single yarn and two-plied yarn in ring spinning,the results show Z-twist zone and S-twist zone of self-twist yarn have the likewise characteristic with two-plied yarn in ring spinning.No twist zone of self-twist yarn is composed of two separated strands,which is the critical zone influencing the yarn performance.Two linear density self-twist acrylic yarns are spun wit... |
