马克隆尼值与成纱质量的相关性能

Correlation between Micronaire value and spinning quality of cotton fiber

为探讨棉纤维的马克隆尼值与其成纱质量的关系,对不同马克隆尼值的原棉进行了单唛试纺,并对反映其成纱质量的各个指标进行测试和相关分析。试验结果表明:在其他条件不变的情况下,棉纤维马克隆尼值对成纱的断裂强度2、mm的纱线毛羽指数、纺纱断头率的影响是非线性的;与成纱条干CV值显著正相关;与成纱棉结数量显著负相关。认为在纺纱过程中,必须根据成纱的用途,合理配置马克隆尼值,才能纺出符合产品质量标准的纱线。

To explore the relationship between Micronaire value and spinning quality of cotton fiber,the paper analyzed series indexes obtained though single bale spinning with different Micronaire values which could affect the yarn quality.The conclusion is that the correlation between Micronaire value and the strength of yarn,hairiness index with a protruding length of 2 mm and end breakage is non-linear,the correlation between Micronaire value and yarn evenness is significant positive,and the correlation between Micronaire value and number of nep is significant negative.So Micronaire value must be allocated rationally according to the use of yarn to ensure the quality of yarn during the course of spinning.
