| Abstract: | Based on the cotton fiber quality inspection data from 2015 to 2019,the cotton quality status and evolution trend in Xinjiang were analyzed.The results showed that the cotton fiber length in Xinjiang showed an overall upward trend,with an average annual increaseof 0.13mm,which continued to increase from 2015 to 2018 and decreased in 2019.The fracture specific strength increased by 0.18 cN/tex,with slight fluctuations between years,and the proportion of fracture specific strength and above has increase.Fiber evenness decreased by 0.35 percentage points overall,increased in 2016 and continued to decline from 2017 to 2019,and the proportion of fibers with high uniformity and above declined overall.The proportion of micronaire in the upper and middle ranks has increased.The fiber length and breaking strength of Xinjiang Corps are better than those of Xinjiang. |
