摘要: The disclosure relates to a method for the surface treatment of a polyester fiber, a modified polyester fiber obtained therefrom, and an engineered cementitious composite containing such modified polyester fibers. The method comprises subjecting the polyester fiber to an alkali hydrolysis to obtain hydrolyzed polyester fiber; applying a solution containing an acid cross-linker and a polyvinyl alcohol to the hydrolyzed polyester fiber, then curing to form a coating having a thickness of sub-micron or micron scale on the polyester fiber, thereby obtaining the modified polyester fiber.
