Abstract:
1. A process for producing a resin composition, comprising steps of: (1) melt-kneading an ethylene copolymer containing an ethylene unit and a glycidyl group-carrying monomer unit with a modified polyolefin resin produced by modifying a polyolefin resin with an unsaturated carboxylic acid and/or an unsaturated carboxylic acid derivative, thereby making a melted resin; and (2) melt-kneading the melted resin with a polyester fiber at a temperature lower than a melting point of the polyester fiber; wherein the resin composition contains 100 parts by weight of the polyester fiber, 1 to 600 parts by weight of the ethylene copolymer, and 0.3 to 500 parts by weight of the modified polyolefin resin, and contents Bx, By, Cx and Cy satisfy following formula (1), Bx being a content of the ethylene copolymer in the resin composition; By being a content of the glycidyl group-carrying monomer unit in the ethylene copolymer; Cx being a content of the modified polyolefin resin in the resin composition; and Cy being a content of a unit of the unsaturated carboxylic acid and/or a unit of the unsaturated carboxylic acid derivative in the modified polyolefin resin.
