锡林速度对盖板花纤维长度分布的影响

研究了锡林速度对盖板花纤维长度分布的影响。用Premier a Qura棉结和短纤维测试仪对4档锡林速度条件下加工生成的盖板花进行了长度检测,分析了不同锡林速度下盖板花纤维长度分布情况。结果表明:锡林速度变化对盖板花纤维长度分布影响较大。随着锡林速度提高,盖板花中12 mm以下短纤维含量有增加的趋势;从盖板花纤维长度分布看,4种锡林速度以450 r/min最利于对盖板花纤维长度分布的改善,该速度下盖板花中18 mm以下纤维所占比例明显高于其他几种速度。认为通过纤维长度分布来评价纤维的分梳情况比只用长度指标更全面、更准确。

Influence of cylinder speed on fiber length distribution of flat strips

Influence of cylinder speed on fiber length distribution of flat strips was studied. The flat strips were produced at four different speeds of cylinder and their lengths were tested with Premier aQura, and the length distribution of different cylinder speeds was analyzed. The results show that fiber length distribution of flat strips is influenced by cylinder speed. The short fiber (less than 12 mm) content of flat strips tends to increase with the increase of cylinder speed. In view of fiber length distribution of flat strips, a cylinder speed of 450 r/min is the best, and at this speed, the fiber (less than 18 mm) the content of flat strips is higher than that of other cylinder speeds evidently. Furthermore, it may be more comprehensive and accurate to estimate carding effect by using of fiber length distribution in comparison with using fiber length parameters.
