【摘要】 为了纺制高品质的甲壳素纤维/棉混纺纱线,对甲壳素纤维/棉混纺纱线的纺纱工艺进行研究。研究表明:配置合理的纺纱工艺参数,甲壳素含量在30%以下时,无论是生产、纱线质量等各方面都是比较可行的。在本实验条件下,锡林与刺辊的线速度比应控制在1.98~2.12之间。对混纺纱条干影响最大的工艺参数是并条机后区牵伸倍数,而梳棉机锡林与刺辊线速度比以及细纱机前罗拉转速对混纺纱的成纱质量也有一定的影响。优化的工艺参数为:梳棉机锡林与刺辊线速度为2.12∶1,并条机后区牵伸倍数1.25倍,细纱机罗拉转速185 r/min。更多还原

【Abstract】 For spinning higher quality chitin fiber/cotton blend yarn,the technology parameters are studied.The experiments show that reasonable technological parameters can guarantee the quality of the blend yarn.The less than 30% of chitin fiber ratio is a reasonable blend ratio.Based on the experiment conditions used in this paper,the best ratio of linear speed of the cylinder to the pin rolls is from 1.98 to 2.12.It also shows that the biggest influence to the quality of blending yarn is coming from the hinder stretching multiples of drawing frame,and the ratio of the cylinder to the pin rolls and the roll rotating speed of spinning frame are also the factors to affect the quality of blending yarn in certain degree.The analysis from the orthogonal tests shows that the best parameters of the spinning technology are the 2.12∶1 of the cylinder to the pin rolls linear speed ratio;1.25 times of the hinder stretching multiples of drawing frame and 185 r/min of the roll rotating speed of spinning frame.更多还原
