DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a mat. More particularly, the present invention relates to a mat having characteristics such as non-slip and good health.

[0002]

2. Description of the Related Art Mats such as shoe wiping mats are placed at entrances of stores and offices. In recent years, rental mats have become widespread, and items used at stores and the like have been collected, washed, regenerated, and reused. The shoe wipe mat is
Shoes must be non-slippery. Further, it is desirable that the stepping comfort is as good as possible. Currently used shoe wiping mats are pile carpets backed with rubber or the like. However, such mats are not yet fully satisfactory in terms of difficulty in sliding and stepping comfort.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shoe wiping mat which is improved in slip resistance and stepping comfort and is also good for health.

[0004]

SUMMARY OF THE INVENTION The object of the present invention consists of a greige machine having a large number of small holes in which a pile yarn layer is tufted on a base fabric, and a backing sheet layer having a large number of projections. This is achieved by a mat in which protrusions are inserted into the small holes and are integrally laminated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
1 is a perspective view of the mat of the present invention, FIG. 2 is a partial cross-sectional view thereof, FIG. 3 is a cross-sectional view of another embodiment, and FIG. 4 is a view showing a method of manufacturing the mat of the present invention. As shown in the figure, the mat of the present invention is formed by laminating a greige fabric 2 in which a pile yarn layer 3 is tufted on a base fabric 4 and a backing sheet layer 1. Greige 2
Are formed with a large number of small holes 7 penetrating therethrough, and the projections 5 of the backing sheet are inserted into the small holes 7 and laminated.

The greige machine is obtained by tufting a pile yarn layer 3 on a base cloth 4. The pile yarn is not particularly limited, and all yarns conventionally used for shoe wiping mats can be used. For example, cotton fiber, rayon fiber,
A spun yarn composed of one or more of polyvinyl alcohol fibers, acrylic fibers, nylon fibers, and other synthetic fibers or a pile yarn composed of multifilaments can be used. Also, the basis weight is not particularly limited, and for example, a pile yarn composed of a single fiber of 10 to 3000 denier can be used.

[0007] The base cloth is not particularly limited, and any base cloth conventionally used for shoe wiping mats can be used. For example, a nonwoven fabric, a woven fabric, and a knitted fabric can be exemplified. As the nonwoven fabric, for example, polyester fiber, polyamide fiber,
Staples such as polypropylene fibers or filaments in the form of thin sheets are used.

The size and shape of the small holes 7 are not particularly limited.
Usually, it is a circle having a diameter of 0.01 to 10 cm. The number is not particularly limited. Also, there is no particular limitation on the arrangement,
Any arrangement such as lattice, concentric, etc. can be used,
A regular arrangement is preferable for positioning in the manufacturing process.

The projections 5 of the backing sheet are provided at positions corresponding to slightly smaller diameters of the small holes so that they can be inserted into the small holes 7 of the greige machine. There is no particular limitation on its shape,
For example, the column can be a hemispherical cylinder. Although the height is not particularly limited, the height of the finished mat is preferably slightly smaller than the thickness of the pile yarn of the greige machine and slightly larger than the thickness.

As the backing sheet, synthetic rubber such as acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), ethylene-propylene rubber (EPDM), natural rubber, vinyl chloride resin, polyurethane Resin etc. is used,
NBR is preferred.

Further, it is preferable to use a conductive rubber as the backing sheet because static electricity can be removed when the mat is stepped on. As the conductive rubber, for example, a known conductive rubber obtained by mixing conductive carbon black with the above rubber can be used.

Further, as shown in FIG. 3, when a small piece 6 that emits fluorescent light is attached to a desired protrusion 5 of the backing sheet,
It is preferable as a mark in a dark place. For example, a fluorescent piece can be attached so as to form an arrow indicating a direction, and can be used as a guide. The shape of the small piece is not particularly limited. For example, the small piece may have a cap shape, a short cylindrical shape, or the like, and may be fitted to the protrusion to be fitted.

The method for producing the mat of the present invention includes:
Although there is no particular limitation, for example, the following method can be exemplified. As a mold, a mold 13 having a large number of projecting tubular portions 14 on a substantially flat surface as shown in FIG. 4 is used. The tubular portion 14 is for allowing rubber to flow into the tubular portion 14 to form the protrusion 5 of the backing sheet layer.
A cushion material 15, a release sheet 16,
Greige 2 having a number of small holes 7, unvulcanized rubber sheet 11,
Other release sheets 17 are set in this order. Greige 2
Is set so that the pile yarn layer is on the mold side, and the small holes 7 are fitted into the mold tubular portion 14. The cushion material 15 is set between the mold 13 and the greige machine so that the pressing pressure applied to the mat during pressing is uniform.

The unvulcanized rubber sheet 11 has a thick portion 12 on one surface of a portion corresponding to the tubular portion. By adjusting the thickness of the thick portion 12, the height of the protrusion 5 of the backing sheet can be adjusted. The shape of the thick part 12 can be, for example, convex or hemispherical. At the time of setting, the thick portion 12 is made to coincide with the opening of the tubular portion of the mold.
The height of the tubular portion is preferably such that when the greige and the unvulcanized rubber sheet are set, the upper end of the tubular portion and the backing sheet surface of the greige have substantially the same height.

The cushion material 15 and the release sheet 16 have small holes so that they can be fitted into the tubular portion. As the release sheets 16 and 17, for example, Teflon (registered trademark) processed glass fiber sheets can be used.

After setting as described above, the pressing machine 18,
Heat and pressurize at 19. In this process, the thick portion 12 of the unvulcanized rubber sheet 11 flows into the tubular portion, and at the same time, the entire rubber sheet is vulcanized and integrated with the greige machine. The vulcanization conditions can be appropriately determined according to the properties of the rubber and the like. Generally, a pressure of 3 to 60 kg / cm ² and a temperature of 100 to 160 ° C.
For 10 to 30 minutes. After vulcanization, the mold is released to obtain the mat of the present invention.

[0017]

Since the mat of the present invention has a large number of so-called wart-shaped projections 5, the shoe and the mat surface are extremely less slippery when stepping on as compared with the conventional mat, making it easier to walk. In addition, the mat as a whole has excellent cushioning properties, and stepping on the wart has a good effect on health. In addition, when a fluorescent piece is attached to the projection, it becomes a mark in a dark place, which is convenient for guidance and the like. Furthermore, there is an effect that static electricity can be removed by using a conductive rubber for the backing layer. Thus, the mat of the present invention
Especially good as a shoe wipe mat
