The combing process and combing quality are closely related, but what kind of process can comb out good products? Different fiber raw materials require different combing processes, and different process principles should be adopted for different raw materials. For example, when processing raw cotton in cotton spinning, the process principles of loosening first and then beating, more loosening and less return, reasonable striking, and early falling and less crushing are adopted. When processing chemical short fibers or medium to long fibers, due to the fluffiness of the chemical fiber raw materials, which do not contain impurities and only have a small amount of fiber defects, the process principle of more combing, less beating, less elimination, and more recycling is adopted. Combine the cotton cleaning machinery and configuration process according to principles. Raw materials with tight packaging, water content, or excessive impurities should generally undergo pre-treatment. The tightly packed raw materials should be pre sorted or unpacked for sufficient time to naturally loosen; Raw materials with excessive moisture content should be dried before combing to improve the combing effect of the materials.
