摘要
文章对毛条制造各工序半制品条子纤维长度的变化进行了系统的分析与研究。试验证明,梳毛条的纤维长度较短,其长度仅为最终精梳毛条纤维长度的60%。针梳特别是理条针流过程可使纤维充分伸直,加工后纤维长度增加约50%。不适当的针梳或精梳过程,不仅不能改善纤维的长度指标,甚至可能使之更加恶化。这是由于针梳或精梳过程产生过高的纤维断裂率,以致使纤维断裂变短的趋势超过伸长增长的趋势。
In this paper, changes in fibre lengths of semi-product slivers during top making areanalysed and tudied systematically The result shows that the fibre lengths of cardedslivers are shorter and numerically qual to 60% of that of the ultimate top. The fibrelengths have been increased effectively in gilling, specially in preparing gilling, byapproximately 50% in length after processing. The fact that fibre lengths an be kept atthe same level or even shortened by the inappropriate gilling of combing shows that morefibre reakage has occured and the property of lengthening has been exceeded by thatof shortening.
