Opening and cleaning cotton process is the first process in spinning process. It takes a series of spinning processes to process raw cotton or various staple fibers into yarn. By opening the corner nails, tearing and striking action of the beaters in each single machine of the combined machine, conditions are created for impurity removal and mixing, preparation is made for separating into single fibers, various raw materials are fully blended in proportion to cotton blending, and cotton rolls of a certain weight, a certain length and uniformity are made for use in the next process.
Opening and cleaning cotton process is the first process in spinning process. It takes a series of spinning processes to process raw cotton or various staple fibers into yarn. Opening and cleaning machine in opening and cleaning cotton process should complete the following tasks.
- Opening
By opening the corner nails, tearing and striking action of the beaters in each single machine of the combined machine, the compacted bulk fibers in the bales are loosened into small cotton bundles weighing 0.3-0.5g, creating conditions for impurity removal and mixing, and preparing for separation into single fibers. In the process of loosening, impurity fragmentation and fiber damage are minimized.
- Removal
At the same time, 50% to 60% impurities in raw cotton were removed, especially cottonseed, seed cotton, sterile seeds, sand and other impurities. The drop of spinnable fibers should be reduced and cotton should be saved.
- Blending
By mixing all kinds of raw materials in proportion to cotton blending, raw cotton can be loosened and blended more evenly.
- Evenly Rolling
The cotton roll with a certain weight, a certain length and uniformity is made for use in the next process. When the blowing-carding unit is used, the output cotton flows into the storage box of each carding machine in the carding process.
