摘要
本文研究了聚酯(PET)纤维的染色及用 DMA 脱除染料后纤维微观结构和性能的变化。分别测定了染色和脱染后纤维的力学性能、热性能及某些表征结构变化的参数,如:双折射、密度及结晶度。结果表明,在不同实验条件下,纤维结构中的不同微结构区不断变化,这些变化大大地影响着纤维的宏观性能。
The structure and property of dyed and disdyed PEt fiber has been studied.After in- vestigating mechanical,thermal properties and some parameters.Of PET fiber such as, birefrngence.Density and crystallinity,it is understood that the change of the microstruc- ture range in the fiber is the most inportant fator which influence the macroscopic proper- ty of the fiber.
