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.

Abstract: A friction clutch includes a clutch boss and a pressure member that change in a relative position in a rotation direction. The clutch boss and the pressure member respectively include cam surfaces that come into contact with each other when the relative position of the clutch boss and the pressure member changes. A first damper member configured to damp a collision between the cam surfaces is provided in the friction clutch. Generation of noise due to the collision between the cam surfaces when the relative position of the clutch boss and the pressure member rapidly changes in the rotation direction is significantly reduced or prevented.

Abstract: Disclosed is a pile knitted fabric containing a ground structure and a pile fiber napped from the ground structure. The pile knitted fabric includes a pile fiber that is knitted into a stitch of the ground structure and napped therefrom; and a stitch composed only of the ground structure, wherein a pile length of the pile knitted fabric is 6 to 25 mm, a continuous length of a pile fiber portion where the pile fiber is knitted into the stitch of the ground structure and napped therefrom is 10 mm or more, a width of a line of a stitch pattern composed only of the ground structure is 1 to 6 mm, a continuous length of the line of the stitch pattern composed only of the ground structure is 10 mm or more, a ratio of the width of the line of the stitch pattern composed only of the ground structure to the pile length is 0.09 to 0.

Abstract: A pile fabric whose pile fibers are prevented from falling off without impairing the texture by fusing only a specific area of the pile fabric. The pile fabric has a ground structure and pile fibers that are intertwined with ground yarns and napped on a front surface of the ground structure. The pile fibers including acrylic fibers and/or acrylic-based fibers and have a softening point lower than a softening point of the ground structure fibers, and are intertwined with the ground yarns. At least part of the pile fibers located outside of the ground yarns are fused but the pile fibers napped on the front surface of the ground structure are not fused. A method of producing a pile fabric includes a contact heating/pressurization step at a temperature equal to or higher than the softening point of the pile fibers and lower than the softening point of the ground structure fibers.
