Dynamic regulation of winding ratio to prevent unparalleled yarn overlapping

The proper winding ratio can prevent yarn overlapping resulting from too small yarn interval when winding,but the yarn separation angle decreases with the spindle diameter increasing,which may make yarn overlapping,edge collapsing and other problems.Therefore,the relationship between the winding ratio and yarn separation angle was analyzed using mathematical methods,and it was found that the grade type decreasing winding ratio can avoid yarn separation angle continuous reducing,insure proper yarn interval without affecting regular arrangement pattern.This paper presents a new method which conducts dynamic regulation of winding ratio,decreases the yarn separation angle,prevents unparalleled yarn overlapping and improves yarn package volume.Examples are given as well.
