摘要
探讨精梳机给棉工艺对短纤维排除效果的影响。建立不同给棉方式下钳板钳口外棉丛长度的数学模型,分析不同给棉工艺对分界纤维长度和重复梳理次数的影响;改变给棉方式及给棉长度,利用aQuraL型纤维长度测试仪测得小卷及不同给棉工艺输出的精梳条中纤维长度分布,计算各片段长度短纤维排除率。结果表明:采用后退给棉时,精梳机对短纤维排除率较前进给棉时高2.5个百分点至15个百分点;精梳短纤维排除率随给棉长度及短纤维长度的增加呈现减小趋势。认为:采用前进给棉、长给棉工艺可提高纺纱效率,降低纺纱成本;采用后退给棉,短给棉工艺更有利于提高纺纱质量。
Effect of comber feeding process on short fiber removal was discussed.Under different feeding methods,a mathematical model of flock length outside nipper was established,influence of different feeding processes on demarcation fiber length and repeated combing times were analyzed.Feeding method and feeding length were changed,aQuraL fiber length tester was used,fiber length distribution in lap and combed sliver with different feeding processes were tested and short fiber removal rate of each segment length was calculated.The results showed that when backward feeding was adoptted,short fiber removal rate of comber was 2.5 percentage points to 15 percentage points higher than that of forward feeding.Short fiber removal rate of combing decreased with the increase of feeding length and short fiber length.It is considered that spinning efficiency can be improved and spinning cost can be reduced by using forward feeding and long feeding process.The use of backward feeding and short feeding process is more helpful to improving spinning quality.
