基于纤维拉伸曲线的短纤纱中纤维张力的数值模拟OA

In order to investigate the effect of twisting on the mechanical properties of fibers in staple yarn,a numerical model for simulating fiber tension in staple yarn was proposed based on the fiber tensile curve,combining the fiber properties,the staple yarn structure and the fiber shrinkage during twisting,and the model was verified by using staple yarns such as cotton,polyester,viscose and vinylon.The results showed that the fiber tension in staple yarn was related to the fiber properties and the twist factors of staple yarn,and it was increased with the increase of twist factors.The predicted MAPE of the numerical model was less than 7％.And the correlation coefficient between the predicted results and the tested results was 0.99,which proved that the model had better accuracy and applicability,and it could provide a basis for further research on the breakage mechanism of staple yarn.
