Abstract
A pile fabric includes a long pile portion and a short pile portion. An average pile length of the long pile portion differs from an average pile length of the short pile portion by 2 mm or more. The long pile portion contains crimped polyester-based fibers in an amount of 60% by weight or more. The short pile portion contains crimped polyester-based fibers in an amount of 60% by weight or more. A crimp removal temperature of the polyester-based fibers of the long pile portion is lower than a crimp removal temperature of the polyester-based fibers of the short pile portion. The crimp removal temperature of the polyester-based fibers of the short pile portion is 90° C. or more and 120° C. or less. Each of the crimp removal temperatures indicates a minimum temperature that satisfies a specific relationship. A method for manufacturing the pile fabric is also provided.
