    Xinjiang Scientific Research Team Solved The Technical Bottleneck In The Production And Processing Of Machine Picked Long Staple Cotton

    2025/3/18 23:39:00 0

    Xinjiang; Long-Staple Cotton

    Once upon a time, Xinjiang machine picked long staple cotton had many impurities, and the problem of quality decline after processing has been puzzling the industrial development. Now, this problem has been successfully solved step by step by the team of Tian Liwen, a leading talent in scientific and technological innovation in Xinjiang. Recently, in addition to obtaining several invention patents from China, Europe and Australia, a high-quality cotton producing country, the team also obtained invention patents in the United States for the high-quality machine picked long staple cotton production method developed by Avati Xinya Cotton Industry Co., Ltd. This is the first cotton cultivation research team in China that has been authorized and recognized both domestically and internationally for the invention and creation of high-quality cotton production technology, injecting new vitality into the development of Xinjiang's long staple cotton industry.

       Breaking through the technical bottleneck in the production and processing of machine-made long staple cotton

    "In the past, Xinjiang machine-made long staple cotton has been plagued by problems such as high impurity content in processing, high fiber loss, and the quality can not meet the needs of the industry." Kong Jie, deputy director of the Cotton Research Institute of the Xinjiang Academy of Agricultural Sciences, said that Xinjiang long staple cotton has the characteristics of long, thin, strong fibers, and has a high reputation in the international market, but in recent years, Xinjiang long staple cotton is faced with high impurity content in seed cotton after machine picking, It is also difficult to clean because it is polluted by foreign matters such as plastic film and drip irrigation belt. In order to improve the processing quality of machine picked cotton and meet the market demand for high cost performance raw cotton, the method of improving the impurity removal strength of seed cotton is usually adopted, but it has caused serious mechanical damage to the fiber, resulting in the promotion of machine picked long staple cotton never reaching expectations.

    Faced with this problem, Tian Liwen's team did not shrink back. "We combed the whole process of planting and processing of long staple cotton, and systematically optimized the relevant technologies and processes such as variety selection, plant spacing configuration, pre harvest preparation, defoliation and ripening, and processing." Tian Liwen, a researcher at the Cotton Research Institute of Xinjiang Academy of Agricultural Sciences, said, "We have put forward a complete process suitable for machining long staple cotton through innovation for the first time, and redesigned the key components of the main trash cleaning equipment and their operating parameters."

    The core of this innovative plan is that, in addition to ensuring the high quality of machine picked seed cotton in the planting process and minimizing seed cotton impurities, it is also proposed that the whole process should include the seed cotton cleaning process, which uses the composite foreign fiber cleaning machine with double channels and large diameter winding roller structure, the inclined seed cotton cleaning machine and the lifting seed cotton cleaning machine; In the lint cleaning link, air flow cleaning machine and lint carding machine are selected to strictly control the impurity cleaning pass.

    At the same time, the team found that the conventional zigzag gin and skin cleaner were not suitable for processing and cleaning of long staple cotton lint. Instead, the roller gin, air flow cleaner and lint carding machine should be used to prevent the mechanical damage of fibers caused by disorderly cleaning of raw cotton circulation. Through unremitting efforts, the team successfully broke through the technical bottleneck, bringing about a turnaround for the development of Xinjiang machine-made long staple cotton.

       International patent licensing brings far-reaching impact

    "It is of great significance that the production method of Xinjiang machine-made long staple cotton has been authorized by the United States patent." Tian Liwen said: "Previously, we have obtained a number of invention patent authorizations in China, Europe and Australia. Supported by these inventions and innovations, we have also won many gold and silver prizes in international influential invention exhibitions such as Nuremberg in Germany and Geneva in Switzerland. The above honors highlight that China's independent innovation ability in the field of high-quality cotton production, including high-quality machine picked long staple cotton production and processing, has reached the world-class level. It shows that Xinjiang's cotton industry is modernized and highly mechanized, and its production mode is in line with the international advanced level. We rely on technology and equipment to improve production capacity. "

    In terms of improving industrial competitiveness, Tian Liwen said that through the application of new technologies, including the selection of suitable machine picked varieties, the construction of machine picked groups in cotton fields, the integration of machine technology in machine picked cotton fields and the management of water, fertilizer and pesticide, as well as the loss reduction processing of machine picked cotton fibers, "Through a series of new technological innovations and applications, we ensure that the cotton produced is of high yield, high quality, low labor and low production costs. Practice shows that this is the most effective measure to enhance the competitiveness of China's global high-quality cotton market."

       Future R&D planning and industry promotion

    Turning to the future team's planning in the research and development of long staple cotton technology, Tian Liwen said: "The production of high-quality long staple cotton involves multiple links, which requires not only the technical breakthrough in a single link, such as the cultivation of machine picked varieties, the finalization of key processing technical parameters, but also the overall promotion of the system. We will give full play to the technical advantages we have mastered, and take the development of more complete technical standards for high-quality machine picked long staple cotton production as the focus of work in the next three to five years. "

    In further promoting the development of Xinjiang's high-end cotton textile industry chain, Tian Liwen said: "From the aspects of variety selection and supporting planting technology, systematic research and development, actively respond to the demands of textile enterprises on the technical standards of high-quality long staple cotton, and better provide technical support for improving the competitiveness of Xinjiang's high-quality long staple cotton market. We hope that through continuous efforts, Xinjiang high-quality cotton, including long staple cotton, will play a more important role in the supply of high-end cotton textile materials, and promote the upgrading and development of the entire industrial chain. "
