In view of the serious defects existing in Xinjiang’s machine-picked cotton, rationally formulating control plans for spinning mills, weaving factories, dyeing and finishing plants, and garment processing plants is the best way to digest and utilize Xinjiang’s machine-picked cotton. Through the following 18 methods to solve the quality defects of machine-picked cotton in Xinjiang can greatly improve the utilization efficiency of machine-picked cotton in Xinjiang:
1) Whitening of batch information through cotton bale inspection Distribution ratios of various grades of cotton, light-point cotton, and light-point dirty cotton to solve the control standards for cotton blending in Xinjiang machine-picked cotton;
2) According to the spinning quality requirements and spinning variety requirements , formulate incoming inspection control standards for Xinjiang machine-picked cotton, and solve the problem of the proportion of machine-picked cotton in mixed cotton;
3) Use single-mark test spinning to solve the problem of controlling the type and quantity of Xinjiang machine-picked cotton defects;
4) Use the single-layer separation principle and multi-layer striking principle of the blowroom process to solve some impurities, defects, and hazardous fibers;
5) Use the blowroom process to the carding process The principle of airflow adsorption and multiple collision friction in the cotton pipeline solves some impurity removal problems;
6) Use the pre-carding process of the blowroom process and the carding process to solve the problem of harmful fiber linters as much as possible The problem of excessive shedding rate and immature fibers;
7) Give full play to the carding efficiency and carding effect of the carding process, and solve the harmful defects, harmful fibers and film-like foreign fibers in cotton bats and cotton bundles. The quantity that exists;
8) The card clothing in the carding process adopts the principle of strong puncture with double-tooth large arc to solve some small-volume impurities and harmful defects in the cotton batting;
9) The combing process implements intensive combing to remove small-volume film-like foreign fibers, impurities, hazardous defects, and hazardous fibers;
10) Utilize foreign fiber removal machines and electronic yarn clearers, Solve and reduce mulched foreign fibers and harmful yarn defects;
11) According to the fabric’s organizational structure, dyeing requirements and end use, solve the use proportion and use grade of machine-picked cotton;
12) According to the changes in Xinjiang’s climate conditions, solve the problem of variety breeding, production management improvement, and use time and standard control of ripening agents and defoliants in machine-picked cotton in northern and southern Xinjiang;
13) Use the changes in color, thickness, and degradability of the mulch film to solve the recycling and degradability of the mulch film to achieve the purpose of solving the problem of heterosexual fibers in the mulch film;
14) Implement regional machine-picked cotton in Xinjiang and seed cotton of different years Grading and grading to solve the problem of Xinjiang machine-picked cotton processing technology and lint quality grade;
15) The blowing-carding, carding, and combing processes should use low speed and light quantity as much as possible to solve the problem The problem of harmful defects in cotton batting, cotton bundles and cotton slivers and the difficulty in controlling the number of harmful fibers;
16) Xinjiang machine-picked cotton is used for fine and extra-fine cotton yarns to solve and control cotton yarn defects and One of the important methods to prevent harmful fibers;
17) New technology in key pre-spinning processes to solve small defects in cotton batting, cotton bundles, cotton layers and mulching foreign fibers;
18) In the early stage of cotton picking, a single device is used to clean up hazardous substances in machine-picked cotton in Xinjiang. </p
