Observation of Damage of Cotton Fiber in the Processes of Blowing, Cleaning and Carding

The quality of the produced yarn mainly depends on the properties of the raw material, its preparation for spinning, the condition of the equipment, and the preservation of the natural quality of cotton fiber during processing. The question of the number of defects in cotton fiber and their total co...
