摘要
通过对单根涤纶长丝进行加捻,研究捻系数对其断裂强力和断裂伸长率的影响,得出涤纶长丝捻系数与断裂强力及断裂伸长率的数学模型,结果表明:涤纶长丝断裂强力与捻系数成二项式关系,断裂伸长率与捻系数成线性关系。
The effect of twist factor upon the breaking strength and breaking elongation rate through twisting a polyester filament yam 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.
