Abstract (en)

In one or more embodiments, the present invention relates to a polyester-based fiber having a crimp with a crimped shape to be changed by a dry heat treatment at 150°C for 10 minutes. It is preferable that the polyester-based fiber having a crimp according to one or more embodiments of the present invention has a crimp satisfying requirements described in (1) below before the dry heat treatment and has a crimp having a secondary crimp frequency satisfying 0.0 crimps/25 mm or more and 1.0 crimps/25 mm or less after the dry heat treatment:(1) a primary crimp frequency of 5.0 crimps/25 mm or more and 30 crimps/25 mm or less and a secondary crimp frequency of 1.0 crimps/25 mm or more and 4.0 crimps/25 mm or less.In one or more embodiments, the present invention provides a polyester-based fiber exhibiting good processability in a carding machine and being able to express a crimp similar to that of natural fur in a napped surface layer portion of a pile fabric through polishing at a relatively low temperature of 90°C or more and 160°C or less, a method for manufacturing the same, and a method for manufacturing a pile fabric using the same.
