【Abstract】 The paper deals with the relationship of the mechanical stretch-bre- aking ratio and the process stretch-breaking ratio for the stretch-breaking machinl of synthetic tow being stretch-broken in the multi-zones,and discusses the difference between stretching and drawing in essence,ln or- der to calculate stretch-breaking sliver in numerical quanfities,this paper deducts the formulas about calculating process stretcg-breaking ratio that using practical stretching,and the calculating results are comparatively tallied with the dates measured in practice.更多还原
