Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-standing carpet which is difficult to be displaced even if it is laid on a carpet, and particularly when the carpet is used as a vehicle interior material such as an automobile, it is not displaced. The present invention relates to a carpet for laying down, which is difficult to do and prevents tufted yarns from falling out and prevents water from permeating the carpet.

[0002]

2. Description of the Related Art Conventionally, in order to improve soundproofing, heat insulation, comfortability, etc., on the floor surface of a vehicle, for example, a needle-punched nonwoven fabric is coated with an aqueous emulsion of a thermoplastic resin having a softening point of 100 to 130 ° C. A moldable fiber mat that has been applied or impregnated and dried, or a non-woven mat made of a mixed fiber of a high melting point fiber such as polyethylene terephthalate and a thermoplastic resin fiber binder having a melting point of 100 to 130 ° C. is heated to produce an automobile. Interior floor carpets are laid by press molding with a mold that matches the floor shape of. In order to prevent dirt and cleaning of the floor carpet, a foot car mat having a convex squeezing pattern on the back surface is placed by molding with a material such as polyvinyl chloride resin or rubber. On the other hand, in houses, offices, hotels, etc., carpets are laid on the floor like vehicles, but laying gorgeous steps or shaggy carpets on all surfaces of these floors will increase costs, so Inexpensive carpets are laid on the entire floor, and luxurious tufted carpets, shaggy carpets and terraces are partially laid on it, or the entire floor surface is laid with high-grade carpets and terraces. When it is being used, it is easy for parts to get dirty easily or get damaged in places such as an uphill entrance or a place where you can step on it under a study desk.Therefore, especially in such a part, the size is smaller, and
An inexpensive replaceable carpet is laid on it.

[0003]

However, such a laid-down carpet that is partially laid down by being laid on top of such a carpet has a problem that the longer the fluff of the carpet laid on the lower side is, The more frequently the standing carpet is stepped on, the more easily the position of the standing carpet laid on the upper side shifts, and often the work of shifting the position of the standing carpet to its original correct position is corrected to correct the shift. Had to do. This deviation is the same in the car mat for the foot of an automobile, and while the conventional car mat has an uneven portion formed on the back surface thereof while driving the automobile, the protrusions on the back surface do not necessarily cause sufficient deviation of the car mat. The prevention function cannot be fulfilled, and a shift may occur.
For this reason, a fixing metal fitting is attached to the back of the foot car mat to attach the mat, but it is troublesome to disassemble and remove the mat during cleaning. In such a state where the car mat is displaced, there is a risk that it may cause discomfort or hinder driving, and that mud brought in by shoes or the like may be scattered on the floor carpet of the automobile.

EFFECTS OF THE INVENTION In such a laid-down carpet of the present invention, a carpet portion layer for the back surface is provided on the back surface side, and the tip portion of the cut pile yarns of the pile fiber layer of the carpet is laid on the lower side. The cut pile yarn (b) is formed so as to pierce into the interior, and even when a force to displace the carpet is exerted, the cut pile yarn (b) does not easily bend and remains pierced. It is possible to prevent the displacement of position 1. Further, since the peeling strength with respect to the carpet laid below is 0, the carpet below is not damaged when peeled off. Further, since the thermoplastic resin film is sandwiched and laminated between the back carpet layer and the facing material, water is prevented from permeating the carpet, and the carpet laid on the lower side is also prevented. It is suitable for use as a foot carpet that is laid on the floor of a vehicle such as an automobile because it is difficult to dislocate even if it is laid on top of it and is extremely easy to peel off. Further, since the cut pile yarn of the back carpet portion is firmly fixed to the primary base fabric by the fiber binder of the non-woven fabric and the resin of the emulsion, the pile yarn does not come off even when the displacement force acts on the carpet.
