  • Publication number: 20210354402
    Abstract: The present invention relates to a molding substrate capable of realizing an exterior material for a vehicle from which the attached snow or ice is more easily peeled off. As a result of continuing studies by the applicant of the present application, it has been found that the problem that the adhered snow and ice hardly peels off, which occurs on a molding base material provided with a fiber base layer containing a core-sheath type conjugate fiber in which the sheath portion is a polypropylene-based resin and the core portion is a polyester-based resin, can be solved by adjusting the mass percentage of the core-sheath type conjugate fiber occupying the fiber constituting the fiber base material layer. Specifically, the present inventors have provided a molding substrate which can realize an exterior material such as an exterior material for a vehicle from which adhered snow or ice is easily peeled off, by being a molding substrate having a fiber base layer having a mass percentage of more than 70% by mass.

  • Patent number: 9610832
    Abstract: An object of the present invention is, even when the design of a weather strip body with a specific gravity of about 0.5 to 0.85 is improved using a nonwoven fabric, to provide a weather strip with excellent trackability and excellent adhesiveness between the weather strip body and the nonwoven fabric. The weather strip of the present invention comprises a weather strip body having a specific gravity of 0.5 to 0.85 and made of an ethylene-propylene copolymer rubber, an adhesive resin sheet comprising random polypropylene and a polypropylene-based thermoplastic elastomer, and a nonwoven fabric, said nonwoven fabric being attached to the weather strip body via the adhesive resin sheet.
