[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 example, for car floor coverings .

[0002]

BACKGROUND ART One only entangled by the conventionally this type carpets needling a web of polypropylene fibers and polyester fibers napped allowed was napped nonwoven fabric is used. As shown in FIG. 7, such a napped nonwoven fabric (1) has a napped layer (3) made of a loop-shaped pile (2) on its surface.
As shown in FIG. 8, a fiber having a substantially circular cross section having a diameter substantially equal to the diameter in the x direction and the diameter in the y direction was used as the fiber f.

[0003]

[0007] However, in the conventional raised nonwoven fabric (1), the pile (2) falls down as shown in FIG. 7B when pressed with a finger, for example. In this state, when viewed from the surface, the pile (2) is mainly
The top of (2) is visible, and the side of pile (2) is mainly visible in section B where pile (2) is lying down. Such a difference in the visible portion of the pile (2) causes a phenomenon that the color tone is different between the portion A and the portion B, and the appearance of the napped nonwoven fabric (1) is deteriorated.

In particular, when used as a carpet for automobiles, the napped nonwoven fabric (1) is lined with a polyethylene sheet or the like and heated to a temperature of about 150 to 220 ° C. to soften the polyethylene sheet and then cold-press the automobile. Formed to fit the floor shape and 30-50 ° C
Although the part is cooled to a certain extent, the molding pressure is increased in a part having a high molding rate, and the pile (2) in that part falls down to a part B having a different color tone from the part A.

[0005] In particular, in the case of a napped nonwoven fabric (1) composed of polyester fibers, the T
g is about 70 ° C.
When cooled at ℃, it becomes Tg or less of the polyester fiber,
The fallen pile (2) is fixed as it is without being restored, and there is a remarkable phenomenon that the color tone differs between the part where the pile (2) has fallen and the part where it has not fallen. However, polyester fiber is heat resistant,
It has weather resistance and is extremely desirable as a material for this type of nonwoven fabric.

[0006]

Means for Solving the Problems The present invention solves the above-mentioned conventional problems by using a polyether having a flat cross section.
The web (10) made of stell fiber is entangled by needling and raised on the back of the napped nonwoven fabric (11).
Lining the port triethylene sheet (15), pre into a predetermined shape
There is provided a scan molded molded carpets (16).

[0007]

When the web (10) made of a fiber having a flat cross section is needled, a loop-like pile (12) of the fiber is formed on the surface.
The nap layer (13) is formed. Such a loop-shaped pile of fibers having a flat cross section has almost no change in color tone when viewed from the top (12A) or from the side. Accordingly
Difference in color tone even collapse the pile (12) by up-less molding Te hardly Okoshira.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 6 by laminating one or more layers of a fiber web (10) and needling it by using a needling device (14). Entangled and napped, a napped nonwoven fabric (11) having a napped layer (13) made of a loop-shaped pile (12) formed on the surface as shown in FIG.

The fibers F constituting the napped nonwoven fabric (11) have a flat shape as shown in FIG. 3, and desirably, x / y =
2/1 or more, more preferably x / y = 5/1 or more is used. Desirable as the fibers Ru polyester fibers der having heat resistance, weather resistance. Polyester above
Polypropylene fiber, polyethylene fiber,
Polyvinyl chloride fibers, polyvinylidene chloride fibers, polyamide
Type of thermoplastic and melt-spinnable fibers
Or it may be used two or more are mixed.

[0010] napped nonwoven fabric (11) according to the fiber F, as shown in FIG. 4 formed form pressure on the front surface is exerted napped layer (13) of the pile (12) B portion also fall partially is formed In the case A, the top of the pile (12A) of the pile (12) is mainly seen from the surface in the part A, and the side (12B) of the pile (12) is mainly seen in the part B. However, as described above, since the fiber F constituting the napped nonwoven fabric (11) has a flat cross section, the top portion (12A) has a specific luster obtained by the dimensional ratio between the x-plane and the y-plane of the fiber F shown in FIG. ) And from the side (12B), there is no discernable color difference. Therefore, the color tone of the part A and the part B hardly changes.

[0011] The napped nonwoven fabric (11) as shown in FIG. 5, for example SBR latex, lined with polyethylene sheet (15) on which is rear surface treatment with an acrylic resin emulsion or the like, is heated to 150 to 220 ° C. and the polyethylene allowed soften the sheet (15), it is by cold press is a molded carpets as shown in FIG. 6 automobile bedding carpet front (16). At this time, <br/> napped nonwoven fabric made of the polyester Le fibers (11), can high temperature heating in the vicinity of 200 ° C., can be softened in a short time a polyethylene sheet (15).

[0012]

[Effects of the Invention] Accordingly, in the present invention, it is possible to obtain a molded carpet that hardly causes a phenomenon in which the color tone of the portion where the pile falls down and the color tone of the portion where the pile does not fall are different.
