摘要： A textile fabric includes a textile fabric layer, a transparent film layer provided on the textile fabric layer, and a surface layer disposed on the transparent film layer. The transparent film layer has a two-layer structure including a first film layer having a first polyetherester-based copolymer and a second film layer having a second polyetherester-based copolymer disposed on the first film layer. The second film layer is provided on the textile fabric layer. A method of manufacturing the fabric includes preparing the textile fabric layer, forming the transparent film layer on the fabric layer, and laminating the textile fabric and transparent film layers through heat treatment.

摘要： The present disclosure relates to a composite resin composition for automotive interior materials and an automotive interior material using the same. The composite resin composition includes a polyester-based resin satisfying a specific intrinsic viscosity range and a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound copolymer and an aromatic vinyl compound-vinyl cyanide compound copolymer satisfying specific melt index ranges. The automotive interior material manufactured using the composite resin composition has advantages in that the automotive interior material is used as an unpainted product while cost is reduced due to material improvement, whereby it is possible to achieve high economic efficiency. In addition, the automotive interior material satisfies required physical properties, such as chemical resistance and mechanical strength, and at the same time exhibits high formability and noise resistance, whereby external appearance quality and emotional quality are improved.
