2. Description of the Related Art In recent years, a nonwoven fabric (including a skin material in some cases) has been used as an automobile molded ceiling material because of its light weight and excellent design. The automotive molded ceiling material made of this nonwoven fabric, for example, the air moves from the surface of the ceiling material to the back surface or from the back surface to the front surface due to the pressure difference due to the opening and closing of the door when getting on and off the car and the flow of air when getting on the car Therefore, there is a problem that the ceiling material adsorbs particles in the air and dirt is easily noticeable. Therefore, the flow of air has been prevented by laminating a film between the back surface of the nonwoven fabric or the skin material and the nonwoven fabric.
However, since this film does not have sufficient elasticity, it tends to break when molded, and it was insufficient to prevent air flow.

The laminated material laminated on the film for the molded interior material constituting the substrate for the molded interior material is preferably a porous material, for example, leather, foamed plastic, woven fabric, knitted fabric, nonwoven fabric, foam (continuous or discontinuous) or Although these composites are used, a fiber sheet such as a woven fabric, a knitted fabric, or a nonwoven fabric is preferred, and a nonwoven fabric is particularly preferred.

[0007] The present invention also relates to a molded interior material obtained by molding a base material for a molded interior material. As the molded interior material, any material may be used, but a molded interior material for a ceiling material of an automobile is particularly preferable.

The film for the molded interior material is made of polyester,
Polyamide such as polyamide, polyethylene and polypropylene, vinyl chloride, polyphenylene sulfide, cellophane, acetate, polystyrene, polycarbonate, polyimide and the like are used, and polyester is particularly preferable because of its excellent recyclability. In this case, the laminated material is preferably made of polyester. The film having concave portions and / or convex portions can be manufactured by, for example, a fold folding machine, a kneading machine, an embossing machine, or the like.

The laminated material constituting the base material for the molded interior material is made of polyester, polyamide, polyolefin such as polyethylene and polypropylene, polyvinyl chloride, polyvinyl alcohol, polyvinylidene chloride, polyacrylonitrile, and polyurethane. One or more of cellulose, cellulose and natural products can be used, but polyester is preferred because of its excellent recyclability.

[0010] The film for the molded interior material is, as in the prior art,
It is arranged so as to be located between the back surface of the laminated material or the skin material (for example, leather, woven fabric, striped material, nonwoven fabric or a composite thereof) and the laminated material, and It can be integrated to form a molded interior material base material.

[0011] The base material for the molded interior material is manufactured by integrating the film for the molded interior material and the laminate material, and optionally the skin material. The integration can be performed, for example, by utilizing the fusing property of the film for a molded interior material, the fusing property of a skin material component and / or a laminate material component, or using a hot melt resin. It can also be performed by bonding or the like. The state of the hot melt resin may be a powder or a web-like sheet. It is preferable to integrate the film so as to have flexibility, and to integrate the whole in a point shape, or to integrate the periphery of the base material for the molded interior material at a point or in a linear shape. Although there is a method, etc., it is particularly preferable to integrate them at a place other than a place where they are greatly deformed by molding.

The molded interior material is manufactured by molding a base material for the molded interior material. Examples of the molding method include a method in which a pair of molds are used to heat and press, It can be performed by a method of performing pressure molding with a pair of molds or the like.

The film for molded interior material of the present invention 1
An example is illustrated. Film for molded interior material 1 of the present invention
Is folded, for example, in two directions as shown in FIG. 1, and the folds 2 allow the film to spread at the time of molding. FIG. 2 shows an example of the molded interior material base material of the present invention. The base material 5 for a molded interior material of the present invention is:
For example, the film 1 for a molded interior material is a laminated material (porous body).
It is located between the skin material 3 and the skin material 4 and is bonded to the laminate material and the skin material. The folds cause the molded interior material film to expand following the elongation of the laminated material (porous body) and the skin material during molding, so that the film is not broken. Examples of the molded interior material of the present invention will be described below, but the present invention is not limited to these examples.

[0014]

EXAMPLE A polyester film was folded vertically and horizontally by a fold folding machine to provide two orthogonal folds, and a film for a molded interior material having a concave portion and a convex portion in a folded state as shown in FIG. 1 was obtained. Manufactured. Then, the film for a molded interior material was placed on a polyester nonwoven fabric made of polyethylene terephthalate fiber and a low-melting polyester fiber, and then the low-melting polyester fiber was heat-sealed to produce a substrate for a molded interior material. The base material for the molded interior material was placed on a lower mold of a molding machine for ceiling materials of an upper mold and a lower mold, and was pressed by the upper mold and heat-molded. After cooling, remove the upper mold,
When the molded ceiling material of the automobile was taken out, the deep drawn portion of the film was not broken, and the folded concave and convex portions of the molded interior material film were spread and slightly flat. The ceiling material was attached to an automobile, and the door was opened and closed. However, since it was sealed by a film that was not broken, air did not circulate and did not adsorb dirt and the like.

[0015]

The film for a molded interior material according to the invention of the present application can be molded without breaking at the time of molding because the film has concave portions and / or convex portions. The film of the present invention is also useful for molded interior materials requiring reinforcement, antifouling properties, abrasion resistance, water repellency and the like. Further, in the base material for a molded interior material of the present invention, even when the base material for a molded interior material is stretched when the base material is deep drawn, a concave portion and / or a convex portion are formed in the film for a molded interior material. Since it is possible to cope with the deformation of the base material for the molded interior material, the film can be molded without breaking at the time of molding. In addition, the molded interior material molded with the molded interior material base material using the molded interior material film of the present invention, especially the molded interior material of the automobile, for example, the ceiling material of the automobile, since the film is not broken, Since the air does not circulate and does not adsorb refuse, the appearance can be maintained.
