Abstract (en)

The present invention relates to a polyester-based fiber having crimps, in which, when the polyester-based fiber is suspended vertically and subjected to dry heat treatment at a temperature of 90°C or more and 120°C or less for 60 seconds under a load of 4 mg/dtex, a difference between a fiber length of the heat-treated polyester-based fiber under a load of 4 mg/dtex and a fiber length of the heat-treated polyester based fiber under no load is less than 3%. This provides a polyester-based fiber capable of imparting good appearance, sag-recovery and voluminousness to a pile fabric, while imparting high crimp removability to a napped surface layer portion of the pile fabric in a polishing process at a low temperature of 90°C to 160°C, and a pile fabric in which the polyester-based fibers are used, a method for manufacturing the polyester-based fiber, and a method for manufacturing the pile fabric.
