Abstract

To deeply study the mechanics performance of PTT fiber and develop the application domain of PTT fiber, in this article, we implement comparative research of tensile performance to PTT fiber and PET fiber respectively in wet condition and dry condition through experiments, and indicate the advantage of PTT fiber. And based on the experiment result, we study the tensile performance of PTT fiber after acid disposal and alkali disposal, which indicates the acid and alkali resistance of PTT fiber and establishes the base to better be applied in the actual production for PTT fiber.
