Abstract

PURPOSE:To easily perform the terminal treatment of an interior material used for a car without taking labor. CONSTITUTION:At least the edge part 3A of the skin material 3 at the terminal of an interior material 1 is lined with a heat-shrinkable sheet 15 and this part is heated to thermally shrink the heat-shrinkable sheet 15 and the edge part 3A of the skin material 3 is involved toward a base material 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automobile ceiling material,
The present invention relates to a terminal treatment method for an interior material such as a door trim and a trim cover of a pillar, and an interior material subjected to the terminal treatment.

[0002]

2. Description of the Related Art As shown in FIG. 3, this type of interior material (1) comprises a base material (2) and a hot melt film on the surface of the base material (2).
(4) consists of a skin material (3) adhered by etc.,
In the terminal, conventionally, the edge portion (3A) of the skin material (3) was wound around the back side of the base material (2) and fixed by a tacker (5) or by bonding with an adhesive.

[0003]

However, in the above-mentioned conventional structure, it is referred to as a tacker or an adhesive for fixing the edge portion (3A) of the skin material (3) wound on the back side of the base material (2). I needed a troublesome means.

[0004]

The present invention provides a base material (2) and a base material (2) as means for solving the above-mentioned conventional problems.
A skin material (3) attached to the surface and a heat-shrinkable sheet (1) backed by at least the edge portion (3A) of the skin material (3).
The heat-shrinkable sheet (15) is heat-shrinked by heating the end portion of the interior material (1) consisting of
The present invention provides a method for terminally treating an interior material (1) in which an edge portion (3A) is wound around a base material (2) side, and the edge portion (3A) of a skin material (3) is heat-shrinked by the terminal treatment. The present invention provides an interior material (1) wound on the side of a base material (2) by thermal contraction of a conductive sheet (15).

[0005]

[Function] In the interior material (1) of the present invention, when the edge portion (3A) of the skin material (3) is heated, the skin material (3) does not shrink and only the heat shrinkable sheet (15) heat shrinks. , Skin material (3) is base material (2)
It will be naturally caught in the side.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 and 2. (1) is a ceiling material for automobiles, a door trim,
Interior materials such as pillar trim covers, the interior materials (1)
Is a base material (2) and a hot melt film (4) on the base material (2)
Alternatively, it is composed of a skin material (3) adhered by an adhesive.

The base material (2) is made of, for example, a resin board, a cardboard, a hard board, a polystyrene foam, a synthetic resin-impregnated polyurethane foam, and is formed into a predetermined shape, and the skin material (3) is, for example, a non-woven fabric, Textiles, synthetic leather,
Alternatively, it is made of a laminated sheet in which polyethylene foam, polypropylene foam, polyurethane foam, etc. are laminated on these, and a heat-shrinkable sheet (15) is lined on the edge portion (3A). The heat-shrinkable sheet (15) is, for example, a heat-shrinkable nonwoven fabric or heat-shrinkable woven fabric obtained by mixing one or more heat-shrinkable fibers such as heat-shrinkable polyester fibers and heat-shrinkable polypropylene fibers, or heat-shrinkable It is a heat-shrinkable plastic film such as a polyethylene film or a heat-shrinkable polypropylene film. Preferred heat shrinkable sheet (1
As 5), there is a polyester fiber non-woven fabric in which 40 to 60% by weight of heat-shrinkable polypropylene fiber is mixed. The heat-shrinkable sheet (15) may be lined on the entire surface of the skin material (3), but it is preferable to line only the edge portion (3A).

When the end portion of the interior material (1) is heated above the heat shrink temperature of the heat shrinkable sheet (15), only the heat shrinkable sheet (15) shrinks and the skin material (3) Since it does not shrink, the edge portion (3A) of the skin material (3) is naturally wound around the back side of the base material (2) as shown in FIG. If desired, a weather strip or the like is tackered to the end of the interior material (1).

[0009]

Therefore, according to the present invention, the terminal treatment of the interior material can be performed very easily.
