Abstract

The invention relates to a non-woven fabric, in particular to the non-woven fabric applied to automobile interior parts. According to the non-woven fabric for the automobile interior parts, through holes which are uniformly distributed are molded on the non-woven fabric; and the radiuses of the through holes are between 0.5 and 2mm, and the distances between the circle tangent sides of any two adjacent through holes are between 2 and 6mm. The through holes are molded on the non-woven fabric and have an effect of accommodating sound and heat. Thus, the non-woven fabric with the molded through holes has better sound insulation effects and heat insulation effects and higher air permeability.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a non-woven fabric applied to automotive interior parts. Background technique [0002] With the rapid development of the automotive industry, automotive interior materials are gradually introducing new ones in the direction of green and environmental protection. Traditional automotive interior parts usually use PU board (polyurethane board) or PP (polypropylene) wood powder board, which has the advantages of good formability and high tensile strength, but its air permeability and toughness are poor, and it is not impact resistant. . [0003] Chinese patent document CN201484319U discloses a car headliner trim panel, which comprises a fabric layer, a composite layer and a bottom layer from top to bottom, and the upper and lower sides of the composite layer are respectively attached with An upper glued film and a lower glued film, the fabric layer is bonded to the upper glued film of the comp...
