VEHICULAR INTERIOR/EXTERIOR PART AND METHOD FOR MANUFACTURING VEHICULAR INTERIOR/EXTERIOR PART
Document Type and Number:
WIPO Patent Application WO/2022/219879
Kind Code:
A1
Abstract:
A vehicular interior/exterior part (10) comprises a base material layer (11) and a sound absorbing layer (15). The base material layer (11) is a fiber molded body containing a thermoplastic synthetic resin (12). In the sound absorbing layer (15), a fiber web (16) entangled with thermoplastic synthetic fibers (18) contained therein, and a cover layer (17) that is a nonwoven fabric containing the thermoplastic synthetic fibers (18) are laminated. The fiber web (16) of the sound absorbing layer (15) is laminated on one surface of the base material layer (11). The sound absorbing layer (15) includes a bonding part, a sound absorbing part (22), and a crimping part (23). The bonding part (21) is solidified in a state in which the thermoplastic synthetic fibers (18) on a surface contacting the base material layer (11) and the thermoplastic synthetic resin (12) of the base material layer (11) are thermally bonded. In the sound absorbing part (22), a fiber web state is maintained with the thermoplastic synthetic fibers (18) not melted. The crimping part (23) is thermally crimped in a state in which the base material layer (11), the fiber web (16), and the cover layer (17) are compressed in a thickness direction.
