Abstract

PURPOSE:To eliminate reduction in a thickness of carpet by arranging a mesh- like thermoplastic synthetic resin layer to be formed on the reverse of a backing layer in a deep drawing molding part of the carpet. CONSTITUTION:A formed carpet 11 is composed of a carpet body 11A, a backing layer 11B to be formed on the reverse of the carpet body 11A and a mesh- like thermoplastic synthetic resin layer 11C to be formed in a backbone part 2 and a side sill part 4 being a deep drawing part on the reverse of the backing layer 11B. Thereby, even if a thickness of the backing layer 11B is reduced, since the mesh-like thermoplastic synthetic resin layer 11C only expand in meshes according to a stretch of the carpet 11, a thickness is hardly reduced, so that an excellent shape holding characteristic can be realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded carpet used for bedding of automobiles, for example.

[0002]

2. Description of the Related Art For example, as shown in FIG. 3, a molded carpet (1) used for automobile flooring has a backbone portion (2), a cross member portion (3) and a side sill portion (corresponding to the floor shape of an automobile). 4) etc. are molded. Conventionally, the molded carpet (1) has a carpet body (1A) and a backing layer (1B) formed on the back surface of the carpet body (1A) as shown in FIG.
And the backing layer (1B) comprises the carpet body (1B).
A) is provided with moldability, rigidity and yarn removal strength, and is made of a thermoplastic synthetic resin such as polyethylene.

[0003]

However, in the above-mentioned conventional molded carpet (1), for example, in the deep drawing molded part such as the backbone part (2) the cross member part (3) and the side sill part (4), The part of the backing layer (1B) is stretched by the tensile force during molding more than the part of the part, resulting in a decrease in the thickness of the backing layer (1B) and a decrease in the rigidity of the part. There was a problem that it occurred.

[0004]

As a means for solving the above-mentioned conventional problems, the present invention provides a carpet body (11A).
And a backing layer formed on the back surface of the carpet body (11A), and a mesh-like thermoplastic composite formed on the back surface of the backing layer (11B) at least in the deep-drawing portion of the carpet (11). A molded carpet (11) comprising a resin layer (11C) is provided.

In the present invention, both a needle carpet having a napped layer formed by needling and a tuft carpet having a napped layer formed by tufting are used as the carpet body of the molded carpet.

In the present invention, the backing layer formed on the back surface of the carpet body is, for example, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyamide, polyacrylate, polystyrene, polyvinyl chloride, polyvinyl acetate or the like. The thermoplastic synthetic resin is used.

In the present invention, the thermoplastic synthetic resin used in the mesh-shaped thermoplastic synthetic resin layer formed on the back surface of the backing layer is the same thermoplastic synthetic resin as the backing layer, and is preferably The same kind of backing layer is used.

[0008]

In the molded carpet (11) of the present invention, the reticulated thermoplastic synthetic resin layer (11C) is formed on the back surface of the backing layer (11B) at least in the deep-drawn molded portion (2, 4), Even if the thickness of the backing layer (11B) is reduced by applying a tensile force to this portion of the carpet (11) during molding to reduce the thickness of the backing layer (11B), the reticulated thermoplastic synthetic resin layer (11C) is
With the stretching of (11), the mesh only expands, and the thickness hardly decreases.

[0009]

EXAMPLES The present invention will be described with reference to an example shown in FIGS. 1 and 2. A molded carpet (11) used for an automobile flooring shown in FIG. 3 is a carpet body as shown in FIG.
(11A), the backing layer (11B) formed on the back surface of the carpet body (11A), and the back surface of the backing layer (11B), as shown in FIG. 4) It is composed of a mesh-like thermoplastic synthetic resin layer (11C) formed in the part. The backing layer (1
Both 1B) and the thermoplastic synthetic resin layer (11C) are made of polyethylene, and the thermoplastic synthetic resin layer (11C) is formed in a bead shape.

As shown in FIG. 1, a felt (5) is attached to the back surface of the molded carpet (11) and is laid on an automobile floor (6). ) And the side sill (4), the carpet (11) is stretched by the tensile force and the thickness of the backing layer (11B) is reduced, but the bead-shaped thermoplastic synthetic resin layer (11C)
The mesh only expands due to the stretching of the carpet (11), and the bead thickness hardly decreases. The felt
(5) is the backing layer (11B) and the thermoplastic synthetic resin layer (1
It is attached to the carpet body (11A) via 1C).

[0011]

As described above, according to the present invention, a deep-drawing-molded portion is reinforced by a mesh-like thermoplastic synthetic resin layer, and a shaped carpet excellent in shape retention is provided.
