The era of machine-picked long staple cotton "processing becomes worse" has passed. Recently, the cotton Research Institute of the Autonomous Region Academy of Agricultural Sciences and Awati Xinya Cotton Industry Co., LTD., jointly developed Xinjiang long wool cotton planting and seed cotton processing methods in the United States to obtain invention patent authorization. The technical solution can effectively solve the problem of fiber damage in Xinjiang machine-picked long staple cotton production and processing, and improve the quality and competitiveness of raw cotton.
"Xinjiang long staple cotton has tailor-made production and processing technology solutions, and its quality control capabilities are internationally recognized." Tian Liwen, a researcher at the Cotton Research Institute of the Xinjiang Academy of Agricultural Sciences, said that China, the United States and Egypt rank among the world's three major long-staple cotton producing countries, and Xinjiang is the only high-quality long-staple cotton producing area in China. Xinjiang long staple cotton fiber color is white, the length is generally up to 37 mm or more, is the best raw material for the production of super high count yarn. However, due to the shortcomings of raw material production technology, especially machine-picked long-staple cotton processing technology, the advantages of Xinjiang long-staple cotton are restricted.
Tian Liwen introduced that Xinjiang has introduced complete sets of long-staple cotton processing equipment and technology at home and abroad, but because the technology is not suitable, the two key quality indicators of cotton fiber length and strength after the processing of long-staple cotton are significantly decreased, and the dilemma of "processing is worse" seriously affects the quality of long-staple cotton, and also weakens its competitiveness in the international market with the world's first-class long-staple cotton brands.
In order to overcome this shortcoming, Xinjiang researchers have been rooted in the production line for a long time, focusing on the actual needs of industrial development. Based on the characteristics of Xinjiang's cotton growing environment and planting management, they have creatively designed the key methods involved in various production links, including the process and equipment, such as the selection of cotton varieties, matching of plant and row spacing, defoliation and ripening, pre-harvest preparation, processing equipment and technology. A set of high quality machine-picked long staple cotton production method suitable for Xinjiang province has been established, and has been gradually brought into effect in actual production.
At present, a number of cotton production and processing enterprises in Xinjiang have promoted the use of this new technology system. The production data show that there is no significant quality difference between the raw cotton fiber length, strength and uniformity indexes of Xinjiang machine-picked long staple cotton produced by this technical program and hand-picked cotton, and the pollution of heterosexual fiber is significantly lighter than hand-picked cotton, which makes up the shortcomings of Xinjiang long-staple cotton machine-picked processing, and significantly improves the production level and industrial comprehensive competitiveness.
Tian Liwen said that the research team will continue to strengthen core technology research in key areas, improve the planting management and processing technology system that is suitable for Xinjiang's special ecological environment, enhance the brand influence of Xinjiang long-staple cotton, and provide scientific and technological guarantee for the supply of high-end cotton textile raw materials.
