摘要
通过试验了解液态水在纱线中传递的方式及路径,对其整个芯吸过程从纱线细度、纺纱方式、组成、捻度4个方面研究了环锭纺和转杯纺单纱的湿传递性能。结果表明:纺纱方式对纱线的芯吸性能影响较为显著,单纱的纤维组成对纱线芯吸影响较大;各种结构的纱线理论上都存在一个最佳捻度,当纱线捻度小于或者大于该捻度时,纱线达到的芯吸平衡高度就会随捻度的变化而减小;芯吸高度与芯吸时间的相关系数均接近1,说明两者有明显的相关性。
The transfer ways and paths of liquid water in the yarn were studied through experiments,and the wetting transfer of the ring spinning and the rotor spinning single yarn was studied from yarn fineness,spinning mode,composition and twist in the whole process of wicking performance.The results showed that the spinning mode had a significant effect on the wicking properties of yarn.Fiber composition of single yarn had great impact on the wicking of yarn.Theoretically,there was an optimal twist for all kinds of yarns.When the yarn twist was less than or greater to the twist,the height of the wicking equilibrium would decrease with the changes of twist.The correlation coefficient of wicking height and wicking time were close to 1,indicating that there was a clear correlation between them.
