1. Blossoming: Mainly loosen the fibers of the production raw materials, and loosen the large tangled fibers into small pieces or bundles through tearing. At the same time, the loosening process is accompanied by mixing and impurity removal. After the flowering process, the raw materials are processed into recycled cotton and packaged to provide raw materials for the production of recycled cotton yarn.
2. Blowing and carding link: The blowing and blowing process is the first process in the spinning process.
(1) Opening: Through the tearing and blowing action of the brad nails and beaters in each unit of the cotton blowing and cleaning machine, the compacted block fibers in the cotton bale are loosened into small cotton bundles weighing 0.3 to 0.5g. Impurity removal and mixing create conditions to prepare for separation into single fibers.
(2) Impurity removal: Remove impurities in the recycled cotton while opening.
(3) Mixing: According to the requirements of the yarn, fully mix the various raw materials (cotton fiber; chemical fiber) according to the proportion of cotton. The better the cotton is opened, the more uniform the mixing will be.
(4) Carding: The mixed cotton fibers are output into the cotton storage box of each carding machine in the carding process to form slivers for use in the drawing process.
3. Drawing: Because the quality and structural state of the card sliver are still far from the requirements of the final yarn, and the straightness and separation of the fibers are poor, therefore, the carded sliver needs to be processed before further spinning. Combination improves evenness and fiber condition. The sliver produced by the draw frame is placed in regular circles in the sliver can for easy transportation and storage for the next process.
4. Yarn: The sliver produced by drawing uses airflow to condense and twist the fibers in the high-speed rotating spinning cup and output them into yarn.
