DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat with a color pattern, and more particularly, to a mat which has a clear boundary between the color patterns and a sharp appearance of the color pattern, and has good clarity.

[0002]

2. Description of the Related Art Conventionally, in order to prevent dust adhering to shoe soles or the like from being brought into a room, mats for collecting dust have been laid at entrances, entrances, etc. of offices, shops, residences, and the like. Has been used. Among these types of mats, so-called color-pattern mats showing patterns, patterns, and the like on the surface are often used.

[0003] In this color pattern mat, pile yarns having different hues become entangled with each other at the boundary of the pattern of the color pattern while being repeatedly used while being washed and regenerated. It exhibits an intermediate color between the colors on both sides of the border, and as a result, the color pattern gradually becomes blurred. If the color pattern or pattern is blurred in this way, especially in the case of a mat for rental, etc., its commercial value is impaired, and the life of the mat as a product despite the dust control performance is still sufficient. Is shortened.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mat and a mat which can be used not only during the initial use of the mat, but also under the extremely severe conditions of repeated rental and washing and regeneration. An object of the present invention is to provide a color / pattern mat in which a pattern can be clearly displayed and the state can be stably maintained forever.

[0005]

According to the present invention, there are provided a plurality of piles having different hues, each of which comprises a base cloth, a tufted pile, and a rubber backing provided on a non-pile surface of the base cloth. In the mat in which the color pattern is revealed by tufting, the base fabric is a staple fiber web driven and fixed on a base made of a woven or nonwoven fabric, and the staple fiber web side is A mat having excellent pattern clarity, characterized in that the pile is tufted, is provided.

[0006]

The important feature of the mat of the present invention is that a base fabric made by driving and fixing a staple fiber web on a base made of a woven or non-woven fabric is used. The color and pattern are revealed by driving in a kind of pile yarn.

[0007] In the mat of the present invention, a staple fiber web is provided on the base of the base cloth, and a pile is driven into the web, so that each tufted pile yarn exists around the web. The staple fiber web forms a substantially upright support. For this reason, even if the pile yarn is once bent by external force,
Even if twisted, it easily restores to its original upright state.

Accordingly, the mat of the present invention does not cause permanent deformation or bending of the pile yarns easily even after repeated washing and regeneration, and the pile yarns are not entangled. Less is. For this reason, even in the border area of the color pattern and the pattern, the pile yarns near the border area having different hues do not entangle with each other or sneak through and the border of the color pattern is blurred to a neutral color, and a clear color is obtained. There is an effect that the pattern boundary line can be maintained for a long time.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 (partial sectional view) showing an example of a color pattern mat according to the present invention, a staple fiber web 3 is driven and fixed to a base 1 of a base cloth. The thing is used as a base cloth. That is, a pile yarn 2 and a pile yarn 2 'having a different hue from the pile yarn 2 are tufted on the side of the web 3 of the base cloth, and a rubber backing layer 4 is formed on the back surface (non-pile surface) of the base 1. Is formed. As the base 1 of the base cloth,
Although not necessarily limited, a woven or nonwoven fabric made of any synthetic fiber such as polyester is used.

On the other hand, as the pile yarn 2 (or 2 '), synthetic fibers such as crimped nylon fibers, vinylon fibers and acrylic fibers, natural fibers such as cotton fibers, and blended fibers of two or more of these are used. You. The pile shape may be either a cut pile or a loop pile, and the pile length and the basis weight may be within the range of mats conventionally used for dust control (dust prevention, dust removal), and generally 3 to 4
The pile length may be 0 mm and the basis weight may be 300 to 4000 g / m ² .

The staple fibers used in the staple fiber web 3 of the present invention include polyester fibers such as polyethylene terephthalate fibers, polyvinyl alcohol fibers such as vinylon, acrylic fibers such as polyacrylonitrile, and polyamides such as nylon. Examples include fibers, synthetic fibers such as polyvinyl chloride fibers, cotton, and other natural staple fibers. The thickness of the staple fiber web 3 is preferably about 5 to 50% of the pile length, and is usually 0.1 mm to 10 mm, preferably 1 mm to 3 mm. The thickness of the fiber varies depending on the thickness of the pile yarn 2 (or 2 ′) and the properties of the pile yarn used, but is usually about 0.1 to 40 denier, which is thinner than the pile yarn 2 (or 2 ′). It is preferred to use

The rubber used for the backing includes acrylonitrile-butadiene copolymer rubber (NBR), styrene-butadiene copolymer rubber (SBR), chloroprene rubber, butadiene rubber, ethylene-propylene copolymer rubber, ethylene-propylene -Diene copolymer rubber, isoprene rubber, isobutylene rubber, polyurethane and the like.

These rubbers are applied in the form of a latex to the entire back surface of the base fabric 1, dried, and then vulcanized to form a rubber backing layer. Further, if necessary, on the rubber backing layer, an uncured rubber obtained by compounding a rubber as exemplified above with a vulcanizing agent, a vulcanization accelerator, a pigment, a reinforcing agent, an extender and the like known per se. A vulcanized rubber sheet may be attached and vulcanized and cured to adhere the rubber sheet. Hereinafter, the color / pattern mat of the present invention will be described in more detail based on examples.

[0014]

EXAMPLE A nonwoven fabric made of polyester fiber having a thickness of 0.1 mm was used as a base cloth of a base cloth, and a 3 mm thick polyester staple fiber having a thickness of 3 denier was formed on the base cloth.
A web having a basis weight of 260 g / m ² was piled up and driven into the fabric, and this was used as a base fabric. Each white, red,
A 2600 denier crimped nylon yarn colored green was driven into the base fabric at a height of 10 mm, and a striped color pattern was formed by a cut pile. The basis weight was 900 g / m2 for the whole cut pile yarn. Acrylonitrile-butadiene copolymer rubber (NBR) having a thickness of 1.0 mm was adhered to the non-pile side surface of the base fabric using a rubber latex to form a rubber backing layer to produce a color pattern mat. (Matt A)

Comparative Example In the example, a color pattern mat was prepared in the same manner as in the example except that a nonwoven fabric having a thickness of 0.5 mm was used as a base of the same type as the example and a web made of polyester staple fiber was not used. Produced. (Mat B)

Visual test of color / pattern clarity The mats A and B were laid on substantially the same floor, used for 7 days under actual use conditions, washed and regenerated under the same conditions, and repeated 40 times. . The sharpness of the color and pattern of the mats A and B after the test was visually determined. The mat A of the present invention had a clear and clear boundary area of the color pattern even after 40 times of regenerating washing. In the case of, the boundary area showed a neutral color due to the pile and was unclear.

[0017]

As described above, the color pattern mat of the present invention
Since a staple fiber web is driven and fixed on a woven or non-woven fabric base as a base cloth, a tufted pile yarn on the base cloth is present around the pile yarn. , The pile yarns are not entangled with each other even after the mat undergoes the washing and regenerating process, and the remarkable effect that the color-coded pattern at the boundary of the color pattern is stably and clearly maintained. Play.
