Key factors of forming operational yarn defects in semi-finished products
The time of formation: in the process of operation
The main reason for the formation is that the normal arrangement of fibers is not well protected
Formation process: the normal stretching and parallel arrangement of fibers is destroyed
The result of formation: the fiber appears abnormal state, such as hook, backward, disordered, the number of cross-section fiber changes and so on
Main features of operational yarn defects in semi-finished products
The main feature of operational yarn defects is that the fibers which constitute yarn defects are relatively disordered, and the fibers are mainly normal fibers.
