The opening process has a lot to do with the quality of opening, but in the end what kind of process can open up a good product, different fiber materials, different opening process, different raw materials should use different process principles.
For example, in the processing of raw cotton in cotton spinning, the following principles are followed:
First, loose, less back, reasonable strike, and premature breakage. When processing chemical short fibers or medium-length fibers, because the chemical fiber raw materials are more bulky, contain no impurities, and contain only a small amount of fiber defects, the process principle of using multiple combs and less to eliminate multiple recycling is adopted. According to the principle of open combination of cleaning machinery and configuration process. For raw materials that are too tight, containing water, or containing too much impurities, they should generally be pretreated. Tightly packed raw materials should be pre-opened, or unpacked and given in sufficient time to loosen naturally; excess water-containing raw materials should be dried before opening to increase the opening effect of raw materials. If you want to open a good product, you must strictly follow the requirements of the opening process.
