China News Service, March 22. According to the WeChat public account of "Shishuoxinyu", on March 20, the China Fiber Quality Monitoring Center released the results of the quality status monitoring of Xinjiang's cotton production and processing process in 2023. This monitoring was implemented by the Xinjiang Regional Fiber Quality Monitoring Agency. The monitoring period is from April 2023 to February 2024. This is the sixth consecutive year that the China Fiber Quality Monitoring Center has monitored the quality status of Xinjiang’s cotton production and processing process.
This year, 21 cotton processing enterprises were monitored, involving 59 cotton farmers, with a cotton planting area of 93,690 acres, 22 cotton varieties, including 14 main local varieties, and 12,860 cotton samples monitored.
Monitoring results show that the quality of cotton in Xinjiang continues to improve. First, the comprehensive fiber quality of the bulk inspection was significantly better than that in 2021 and 2022. Second, the quality of high-quality varieties is outstanding. The variety Jinken 1775, the fiber length and breaking ratio strength reach the "double 31" standard; varieties such as Yuanmian No. 8, Xinta Mian No. 3, Huiyuan 720, Xinlu Zhong 61, Xinlu Zao 65, Xinlu Zhong 54, etc. The fiber length and breaking ratio strength both reach the "double 30" standard. Third, scientific field management has a greater impact on cotton quality. Appropriate planting density and fertilizer and water application are important guarantees for the normal development of cotton fibers. Fourth, reasonable processing technology is conducive to maintaining the intrinsic quality of cotton. The processing technology has a prominent impact on cotton quality. The seed cotton cleaning process has a negative effect on fiber length and length uniformity, has a small impact on the specific breaking strength and micronaire value, and has a significant positive effect on the color grade. The ginning process has a significant positive effect on the specific fiber breaking strength. The negative effect has little effect on fiber length, length uniformity, micronaire value and color grade; the skin cleaning process has a negative effect on fiber quality, in which fiber length, length uniformity and breaking specific strength all decrease, and the micronaire value Less affected, color levels improved but only slightly.
