Pile fabric and manufacturing method therefor

A pile knitted fabric, comprising:

• a knitted pile portion that comprises a long pile portion and a short pile portion, wherein
• 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 comprises crimped polyester-based fibers in an amount of 60% by weight or more,
• the short pile portion comprises crimped polyester-based fibers in an amount of 60% by weight or more,
• a crimp removal temperature of the crimped polyester-based fibers of the long pile portion is lower than a crimp removal temperature of the crimped polyester-based fibers of the short pile portion,
• the crimp removal temperature of the crimped polyester-based fibers of the short pile portion is 90° C. or more and 120° C. or less, and
• each of the crimp removal temperatures indicates a minimum temperature that satisfies the following numerical formula (1):
• (A−B)/A×100<3(%) (1)
• where, in the formula (1),
• A represents a length of a fiber bundle of the crimped polyester-based fibers under a load of 4 mg/dtex after the fiber bundle is subjected to dry heat treatment at a predetermined temperature for 60 seconds under a load of 4 mg/dtex, and
• B represents a length of the fiber bundle of the crimped polyester-based fibers under no load after the fiber bundle is subjected to the dry heat treatment at the predetermined temperature for 60 seconds under a load of 4 mg/dtex.
