Abstract
The effect of twist factor upon the breaking strength and breaking elongation rate through twisting a polyester filament yarn was studied,and the quantitative analysis of the relation between breaking strength and breaking elongation rate and the twist factor was induced.The results showed that the breaking strength had binomial relations with twist factor,and the breaking elongation rate had linear relations with twist factor.
