The processing of raw materials is an important condition that determines the quality of felt production. The raw materials of felt mainly include regenerated wool from tannery and woolen mills, as well as raw wool.
The specific processing method for raw materials is to open large pieces of raw wool into loose small pieces, and remove the sandy soil impurities in the wool fibers while opening. The opened raw wool is relatively loose, and it is easy to dry after scouring to ensure uniform drying. The opened wool creates rational conditions for the processes of carding, elastic wool, and wool, which can reduce the damage and elasticity of the card clothing of the carding machine. Only the pre-treatment of the raw materials can produce high-quality felt materials with the impact load of the needles of the wool machine.
Because raw wool and regenerated wool contain a lot of oil, sand, dung eggs, dust, grass thorns, feed, etc., if these impurities are not removed, it will have a great impact on the process and quality of the subsequent processes.
