Document Type and Number:
WIPO Patent Application WO/2022/213252
Kind Code:
A1
Abstract:
A nonwoven fabric (100) includes polymeric fibers (102) and particles (104) in contact with the polymeric fibers (102) and has an elongation at break of at least 60% and a thickness that changes by less than about 60% after a pressure of at least 300kPa at a temperature of at least 120℃ is applied for at least 10 minutes and then removed. A pneumatic tire (200) can include the nonwoven fabric (100) for absorbing sound. A method of making a pneumatic tire (200) includes providing a pre-vulcanized tire (212) including a nonwoven fabric (100) and molding the pre-vulcanized tire (212) at a temperature of at least 120℃ and a pressure of at least 300kPa for at least 10 minutes to form the pneumatic tire (200).
