Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A weather strip comprising 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 a mixture of 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, wherein the nonwoven fabric is a decorative nonwoven fabric having a decorative layer that comprises an adhesive containing a pigment printed on one surface of the nonwoven fabric, and wherein, in a thickness direction of the decorative nonwoven fabric, the thickness of a region into which the adhesive containing the pigment is not penetrated in the decorative nonwoven fabric is 10 μm or less. 2. The weather strip according to claim 1 , wherein the adhesive resin sheet has a 25% modulus strength of 10 to 28 N/5 cm. 3. The weather strip according to claim 1 , wherein the weather strip body has a 25% modulus strength of 500 kPa or more. 4. The weather strip according to claim 2 , wherein the weather strip body has a 25% modulus strength of 500 kPa or more.
