フトな風合および軽量化が要求されている。[Conventional technology] Traditionally, automobile interior materials such as ceiling skin materials, pillar materials, door materials, and package materials have been made of composite materials such as fabrics or polyvinyl chloride sheets laminated with urethane foam, or soft wind panels. Nonwoven fabrics and the like have been used, but in recent years, with the increasing use of interior materials for automobiles, there has been a demand for these interior materials for automobiles to have a soft texture and be lightweight.

を完成するに至つた。[Problems to be solved by the invention] In view of the above-mentioned problems, the present inventors developed a non-woven fabric and a foamed fabric that is not only easy to manufacture but also has a soft texture and is lightweight. As a result of extensive research into creating an automobile interior material with a strong adhesive bond to the latex layer, we applied a foamed latex made by mechanically dispersing gas to one surface of a nonwoven fabric, and created a material with a thickness of 1 The inventors discovered a completely new fact that all of the above-mentioned problems can be solved by impregnating only 1/4 to 1/2 of the amount, and have completed the present invention.

材に関する。[Means for Solving the Problems] That is, in the present invention, a foamed latex layer in which gas is mechanically dispersed is laminated on one surface of a nonwoven fabric, and the foamed latex layer has a thickness of 1/1 of the thickness of the nonwoven fabric. This invention relates to an automobile interior material impregnated by 4 to 1/2.

いものである。[Operations and Examples] The automobile interior material of the present invention has a foamed latex layer formed by mechanically dispersing gas on one surface of a nonwoven fabric, and has a thickness of 1/3 to 1/2 of the thickness of the nonwoven fabric. However, unlike interior materials made of non-woven fabrics, the automobile interior materials obtained in this way have a foamed latex layer on the surface, so only the soft wind resistance that the non-woven fabric itself has. However, it has the supple elasticity of a foamed latex layer, and is resistant to wrinkles during molding.

不織布の一方表面上に発砲ラテツクス層が設けら
れるので通常１mm〜15mmであるのが好ましい。 The basis weight of the nonwoven fabric cannot be determined because it varies depending on the type of fibers making up the fabric, but it is usually adjusted to 80 to 150 g/m 2 . If the basis weight is smaller than 80~/ m2 ,
If the thickness of the nonwoven fabric is too thin, the wind strength of the nonwoven fabric is lost, and if it exceeds 150 g/m 2 , the weight of the nonwoven fabric becomes too large, making it impossible to obtain the desired lightweight interior material for automobiles. Although the thickness of the nonwoven fabric varies depending on the basis weight of the nonwoven fabric, it is usually preferably 1 mm to 15 mm since a foamed latex layer is provided on one surface of the nonwoven fabric.
