織布内装表皮材に関するものである。This relates to automotive interior skin materials such as rear packages and door trims. More specifically, the present invention relates to a nonwoven interior skin material used when extruding and foaming a nonwoven interior skin support base material such as a polyolefin resin such as polypropylene or polyethylene, as well as adhesive lamination of the nonwoven interior skin material in one step. .
近年、自動車内装表皮材は繊維化傾向にあり、更に軽量
化９種々形状への易成形加工性、コストダウン等の要求
が高まるにつれ、不織布内装表皮材が多く用いられる様
になってきた。In recent years, there has been a tendency for automobile interior skin materials to become fibrous, and as demands for weight reduction, ease of molding into various shapes, cost reduction, etc. have increased, non-woven interior skin materials have come to be used more frequently.

になってきた。Furthermore, in consideration of moldability, heat insulation, and weight reduction, the molding base material that supports the nonwoven interior skin material has been conventionally used, such as chimp board, resin felt impregnated with phenolic resin, and tampon. From the base material, it is lighter and
In addition, plastic foams with excellent heat insulation properties and moldability have come into widespread use, and in particular, polyolefin foams such as polypropylene and polyethylene have come into widespread use.

等のバラツキによる基材厚さの変動。However, in this extrusion molding of a foamed base material such as olefin resin and simultaneous lamination with a skin material, the foaming of the foamed base material is performed while the surface of the base material such as olefin resin is still in a molten state. Because it is necessary to laminate under low pressure conditions that do not crush the layers, the strength of the adhesive depends on variations in the thickness of the base material due to variations in the condition of the laminated surface of the nonwoven skin material, the foaming ratio of the base material, etc.
加圧ロールの温度、クリアランス、周辺環境温度の変動
等により不安定になり満足のいく接着強力が得られない

のが得られていない。Therefore, in order to obtain stable adhesion strength, ppHAII, which is the same material as the polyolefin foam base material, is applied to the nonwoven fabric skin material side.
It has been proposed to mix polyolefin fibers such as K, or to apply an adhesive resin powder or sheet-like material made of hot melt resin such as polyamide or polyester to the back side, but none of these methods require lamination or molding. There are various problems such as low adhesion strength of processing parts, visibility problems in appearance, decrease in light resistance, abrasion resistance, cost, etc., and it is not possible to obtain a satisfactory product.
