摘　　要：研究棉花加工过程中不同回潮率对皮棉加工质量的影响。通过对新疆生产建设兵团第八师某轧花厂皮棉公检数据中直接受棉花加工过程影响的棉纤维长度、长度整齐度指数及断裂比强度的统计,分析棉纤维长度、长度整齐度指数及断裂比强度随打包皮棉回潮率增加的变化趋势,并拟合出对应数学模型。研究结果表明:回潮率对选取的皮棉加工质量指标影响显著,当回潮率低于7%时,随着回潮率的增加所选取的皮棉加工质量指标向好;当回潮率高于7%时,所选取的皮棉加工质量指标出现较大的波动。认为:较适宜轧花环节的籽棉回潮率为8.5%。The influences of different moisture regain on ginned cotton processing quality during the cotton pro⁃cessing were studied.By the statistics of cotton fiber length,length uniformity index and breaking specific tenacity af⁃fected by cotton processing from the public inspection data of the ginned cotton for some cotton ginning mill in Xinji⁃ang Production and Construction Crops No.8 division,the change trend of cotton fiber length,length uniformity in⁃dex and breaking specific tenacity against the increase of moisture regain for packaged ginned cotton were analyzed.The corresponding mathematical model was matched.The research results showed that the moisture regain had sig⁃nificant influence on the processing quality index of selected ginned cotton.When the moisture regain was lower than 7%,as the increase of moisture regain,the processing quality index of selected ginned cotton was better.When the moisture regain was higher than 7%,there was a large fluctuation for the processing quality of the selected ginned cotton.It is considered that the seed cotton moisture regain suitable for ginning process was 8.5%.
