The study is to explore the effect of yarn feeding angle and tension on the plated coverage (mis-plated) which using the same yarn count (both ground yarn and fact yarn)in the V-bed flat knitting machine. On the other hand, we use the DigiEye imaging system to evaluate the plated coverage (mis-plated). The result is that when the feeding angle of ground yarn is greater than face yarn and the feeding tension of ground yarn is also greater than face yarn, we could efficiency to solve the mis-plated issue. The conclusion is properly control the feeding tension could be a main way to solve mis-plated.
