Document Type and Number:
WIPO Patent Application WO/2011/083622
Kind Code:
A1
Abstract:
Provided is an annular sound-absorbing material which can be used for the inside of the air chamber of a tire, and which exerts excellent noise reduction effects. Also provided is a tire, the air chamber of which is provided with said annular sound-absorbing material, and which exerts excellent noise reduction effects. An annular sound-absorbing material contains a fiber structure, and has a thickness of 1mm or more, wherein the fiber structure fulfills the following requirement (1). The requirement (1) being that the fiber structure comprise a nonelastic crimped staple fiber and a heat-bonding composite staple fiber, in which a polymer having a melting point that is lower than that of the polymer constituting the nonelastic crimped staple fiber by 40°C or more is arranged on the surface of the heat-bonding composite staple fiber as a heat-bonding component, wherein: the nonelastic crimped staple fiber and the heat-bonding composite staple fiber are blended in a manner such that the weight ratio is between 90/10 to 10/90; the adhering points, in which the heat-bonding composite staple fiber intersect and are heat bonded to one another, and/or the adhering points, in which the heat-bonding composite staple fiber and the nonelastic crimped staple fiber intersect and are heat bonded, are dispersed in the fiber structure; and the heat-bonding composite staple fiber and the nonelastic crimped staple fiber are arranged in the thickness direction of the fiber structure.
