Because raw wool and regenerated wool contain a lot of oil, sand, dung, eggs, dust, grass thorns, feed and so on, especially the gray hair from leather factories contains a lot of gray soil. If these impurities are not removed, they will have a great impact on the process and quality of subsequent processes. The specific treatment principle is to turn large raw wool into loose small pieces after loosening, and at the same time when loosening. Remove 15-30% of sand impurities from wool fibers. The loosened raw wool is loose and easy to dry after washing, which ensures even drying. The loosened wool creates reasonable conditions for carding, elastic wool, wool and other processes. It can reduce the damage of Carding Clothing of carding machine and the strike load of carding needle of elastic wool machine.
