Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carpet, a mat,
The present invention relates to rugs used indoors and outdoors, such as tile carpets and artificial grass. 2. Description of the Related Art Polyvinyl chloride, polyolefin, and the like are provided on the back surface of a fiber surface material such as a pile fabric and a needle punch fabric.
2 mm thick made of thermoplastic resin composition such as bitumen
Carpets and artificial turf, etc., which have the above-mentioned backing layers laminated to impart dimensional stability and are flexible and fit to the floor surface, etc., are cut into small pieces of about 1 m ² or less. It is used as a mat or tile carpet.
Since the backing layer is made of a thermoplastic resin composition, the rug layered on those thick backing layers is slightly compressed during use by being pressed down during use, and is easily stretched vertically and horizontally by that much,
As a result, there arises a problem that the periphery of the rug is warped upward and the foot is easily caught. In order to prevent this, a method of interposing a non-stretchable glass fiber cloth inside the backing layer is adopted. [0003] In a rug 13B in which a thick backing layer 12 made of a thermoplastic resin composition is laminated,
The backing layer 12 having the glass fiber fabric 15 interposed therebetween has good dimensional stability and does not show any warpage of the periphery during use, but the pile fabric or needle punch fabric 1 as the surface material is used.
1 is obtained by applying the thermoplastic resin composition thickly and laminating the backing layer 12, even if the glass fiber fabric 15 is inserted at the time of the coating, this is applied to a tile carpet or mat. When cutting in order to make the tile carpet 13B tend to be slightly warped, such tile carpet 13B is laid out with the perimeters of the tile carpet 13B, and the perimeter rises slightly from the floor surface 24 during walking. The tile carpet 15B gradually shifts easily due to dust entering between the back surface and the floor surface 24 from the raised peripheral edge, or the floor carpet 15B. In order to solve this problem, the backing layer 12 may be made heavy and the periphery thereof may be bent downward by the weight of the backing layer 12. However, this increases the cost, and practically, the backing layer 12 is laminated. Is meaningless. or,
Backing layer 1 by blending a large amount of a plasticizer with a thermoplastic resin composition
There is also a method of making the 2 more flexible, but in this case, disadvantageously, such as the warp of the periphery due to use becomes severe, and the rug 13B becomes flammable. Accordingly, the present invention has as its main object to economically obtain a rug whose back edge is slightly warped toward the back side without making the backing layer 12 unnecessarily heavy. A rug 13 such as a carpet, a mat, a tile carpet, and an artificial lawn according to the present invention.
Is a fiber surface material 1 such as a pile fabric, a needle punch fabric, etc.
In a rug 13 in which a backing layer 12 made of a thermoplastic resin composition is laminated on the back surface of the rug 1, the backing layer 12 has a heat-shrinkable fabric 14 at a temperature of 170 ° C. or less, and the periphery is on the back side of the rug 13. It is characterized by being warped toward. The thermoplastic resin composition 18 for forming the backing layer 12 is prepared and applied in the form of a viscous fluid, and any material that requires heating in the process of forming the backing layer 12 may be used. The shrinkable fabric 14 is applied while the thermoplastic resin composition 18 is in a fluid state and inserted into the backing layer 12. Examples of the heat-shrinkable fabric 14 include a drawn polypropylene fiber yarn and a polyethylene fiber yarn.
A coarse woven fabric, knitted fabric or non-woven fabric which becomes a low melting point synthetic fiber yarn such as an acrylic fiber yarn or a vinyl chloride fiber yarn is used, and a high melting point synthetic fiber yarn such as polyester fiber or nylon is used. It is sufficient if the shrinkage of about 0.1 to 30% occurs in the entire cloth 14 at a temperature of 80 to 170 ° C. In the backing layer 12, a glass fiber cloth 15 may be inserted as a core material. In this case, a heat-shrinkable cloth 14 is inserted on the back side of the glass fiber cloth 15. In other words, the fiber surface material 11, the glass fiber fabric 15,
The heat-shrinkable fabrics 14 are overlapped in this order. As the fiber surface material 11, a tufted carpet or a needle punch felt carpet is applied.
The tufted carpet may be made as an artificial lawn. The thickness of the backing layer 12 may be about 1 to 5 mm. Hereinafter, the present invention will be described specifically with reference to the illustrated embodiments. EXAMPLE A thermoplastic resin composition 18 having the following composition was applied on a release belt 16 with a doctor blade 19 to a thickness of 1 m.

(Weight 110 g / m ² , heat shrinkage rate at 150 ° C. × 10 minutes; 45%, width: 55%) and woven fabric 15 of glass fiber yarn (weight 45 g / m ² ) The woven fabric 14 is overlaid on the previously applied coating layer 20, the woven fabric 15 of glass fiber yarn is overlaid thereon, and the thermoplastic resin composition 18 is again placed on the woven fabrics 14 and 15 with a doctor. It is coated and laminated to a thickness of 1.5 mm by a blade 21, and a tufted carpet (raw material) not backing a secondary base fabric is superimposed on the coated layer 22, and then passed through a heating zone 23 at 170 ° C. for about 10 minutes to be thermoplastic. Resin composition 1
8 was solidified and cut into 50 cm squares to form a tile carpet 13 serving as a backing layer 12 and a tufted carpet 11.

Then, when this was turned upside down and placed on the floor surface 24, the peripheral edge warped upward 2.5 mm from the center as shown in FIG. COMPARATIVE EXAMPLE The thermoplastic resin composition 18 used in the above embodiment was applied and laminated to a thickness of 1 mm on a releasable belt 16 by a doctor blade 19, and a glass fiber was applied on the applied layer 20. The woven fabric 15 (having a basis weight of 45 g / m ² ) is overlaid, the woven fabric 15 made of glass fiber yarn is overlaid thereon, and the thermoplastic resin composition 18 is again placed on the woven fabric 15 by the doctor blade 21.

2 and the tufted carpet fabric 11 is superimposed thereon, and then passed through a heating zone 23 at 170 ° C. for about 10 minutes to solidify the thermoplastic resin composition 18, cut into 50 cm squares, and formed into a backing layer 12 and a tufted carpet 11. Made a tile carpet 13B. When the tile carpet 13B was laid on the floor surface 24, as shown in FIG. 3, the peripheral edge was warped upward by about 1.5 mm from the center. The backing layer 1 in the rug 13 according to the present invention
2, the heat-shrinkable fabric 14 is interposed. Although the heat shrinkage of the fabric 14 is promoted by heating during the formation process of the backing layer 12,
The heat shrinkage stress becomes latent in the backing layer suppressed by the high-viscosity thermoplastic resin composition 18 which is the main material of the backing layer 12. As a result, the resulting rug 13 tends to continually bend back to the back side due to this latent shrinkage stress, so that it does not bend to the front side and is prevented from warping up during use. [0015] Therefore, conventional mats used for frequently stepped places such as entrance mats and car mats need to be fitted with a rim material in order to prevent the peripheral edge from rising. According to the present invention, this is required. It becomes unnecessary and backing layer 1
The curving to the front side can be effectively stopped without making the 2 heavy, and thus a rug 13 such as a mat, a tile carpet, etc., which is thin, light, and excellent in shape stability can be obtained economically, and the practicality of the present invention is extremely high. .
