摘要
对扁平形聚酯纤维和圆形聚酯纤维的结构和性能进行了研究。结果表明 ,扁平形初生丝的双折射比圆形丝大 ;扁平丝的比表面积、沸水收缩率和功系数都比圆形丝大 ,而其杨氏模量和断裂强伸度却比圆形丝小 。
The structure and properties of flat section and circular polyester filament were studied through measuring birefringence, sonic modulus and work coefficient ect. of that. It is found that as specific surface area and birefringence of as spun yarn of flat section filament are greater than that of circular filament, the sonic modulus, breaking tenacity and extension are finer than that of circular filament. The test results also show that the shrinkage in boiling water and work coefficient are greater than that of circular filament.
