[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf effective for use in walking paths.

[0002]

2. Description of the Related Art Conventionally, artificial turf has been often laid on a walk path at a construction site, a golf course, a park, or the like for the purpose of protecting the appearance and the legs of athletes and workers.
However, it is generally a green-based monochromatic color. Some artificial turf for walk paths are patterned with paint for direction indication and danger area indication, but their durability is a problem, and research on colorants to firmly fix the display part has been conducted. (For example, Japanese Utility Model Publication No. 56-43103).

[0003]

[Problem to be Solved by the Invention] In particular, in the artificial turf path at the construction site, a safety purpose display is required, but the durability of the colorant which firmly fixes the display part is not enough. Naturally, it is inferior and costs increase. Further, it is technically very difficult to design and display only the display section by changing pile yarns.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an artificial turf for a walkway in which a display portion is easily formed by using an original pile yarn. High-cut pile 3 of the original pile yarn 1 that becomes the hue
And then, the dyed pile yarn 2 of hue and different color artificial turf mainly as a low pile loops 4, by implanting the base fabric alternately dyed <br/> pile yarn dichroic in gauge direction, on the surface Is artificial
In the artificial turf dyed pile yarn 1 serving as the hue of the grass principal can be confirmed, by changing the pile having a constant region, the human
The original pile yarn 1, which is the hue mainly of artificial turf , is hidden as a low-loop pile, and the original color is different from the hue mainly of artificial turf.
This is a walking path artificial turf in which a display portion is formed by the appearance of the arrival pile yarn 2 as a high cut pile on the surface.

Hereinafter, the structure will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of the artificial turf for a walking path according to the present invention in a gage direction of a part without a handle. The original pile yarn 1 and the different-color original pile yarn 2 are respectively high cut pile 3 and low
Hairs are alternately planted as loop piles 4, and only the color of the high-cut pile 3, that is, the original pile yarn 1 can be seen on the surface. Next, FIG. 2 shows a sectional view of the display portion in the gauge direction. In the area A, the pile shape is changed, that is, the original pile yarn 1 is set as a roll pile 4 and the different color original pile yarn 2 is set as a high cut pile 3. Therefore, the hue of the original pile yarn 2 which was not visible on the surface as the roll pile 4 in the patternless portion can be seen on the surface as the high cut pile 3 in the region A, and a display portion can be formed.

Here, the pile lengths of the high cut pile 3 and the roll pile 4 are determined in the natural state after the planting.
If the color of the thread of the loop pile 4 is hardly visible on the surface, the display portion can be formed, and a slight difference in length may be provided. Preferably, the difference is 5 mm or more. The roll pile 4 also maintains the uprightness of the adjacent high cut pile 3.

The raw materials of the pile yarns 1 and 2 may be appropriately selected from monofilaments and slit yarns of thermoplastic synthetic resins such as polyolefins, polyamides and polyesters used for ordinary artificial turf. In addition, in the artificial turf for the walkway of the present invention in which the display portion is formed using pile yarns having different rigidities, not only the display on the appearance but also the feeling when stepping on the display portion is a place without the display portion. Because it is different, when used on a construction site, it is effective as a double indication of safety.

The pile thread can be produced not only in the tuft style, but also in the Wilton, Axminster, Russell style and the like.

[0009]

According to the present invention, since the display portion is formed on the artificial turf using a combination of high cut and roll loops using the original pile yarn, there is no need to use a coloring agent, and the durability is reduced at a low cost. This makes it possible to manufacture artificial turf for walking paths that do not have any.

[0010]

EXAMPLE 1 Nylon was selected as a synthetic resin, and 0.6% of a cyanine green dry color and 0.9% of an azo yellow dry color were used as coloring pigments. The mixture was added at an extrusion temperature of 250 ° C., a stretching temperature of 180 ° C., an annealing temperature of 185 ° C., and a stretching ratio of 4.5 to produce green and yellow slit yarns of 600 denier. These slit yarns were bundled, twisted twice / inch, and used as pile yarn.

A polyester nonwoven fabric having a basis weight of 120 g / m ² was selected as a base fabric, and was tufted as a high cut and a roll pile alternately at 5/32 kPa, 10 stitches / inch. At this time, green color is applied to the high cut (pile length 12 mm) over the entire surface,
A yellow pile yarn was used for a roll (pile length: 6 mm). The display portion of the arrow and the character has a clear display portion of yellow by using green pile yarn as a roll and yellow pile yarn as a high cut.

Example 2 Polypropylene was selected as a synthetic resin, and 0.6% dry color of cyanine-based green was added as a coloring pigment. The extrusion temperature was 260 ° C., the stretching temperature was 160 ° C., the annealing temperature was 170 ° C., and the stretching ratio was 100%. A quadruple, 300 denier green flat monofilament was produced. Eight green flat monofilaments were bundled, twisted twice / inch, and further crimped at 18 ridges / inch by a compression shaping type crimping machine, and used as green pile yarn. Next, polypropylene was selected as a synthetic resin, and azo red dry color -0.5 was used as a coloring pigment.
%, And a 300-denier red flat monofilament was produced under the same conditions. 14 red flat monofilaments were bundled, twisted twice / inch, and further subjected to a crimping process of 18 ridges / inch with a compression shaping type crimping machine, and used as a red pile yarn. In this case, the green pile yarn is 2,400 denier, whereas the red pile yarn is 4,200 denier, so that the rigidity of the red pile yarn is considerably large. .

A polyester nonwoven fabric having a basis weight of 120 g / m ² was selected as a base fabric, and a pile yarn was tufted at 5/16 ke / s and 8 stitches / inch. At this time, green was used for the high cut (pile length 15 mm) and red pile yarn was used for the roll (pile length 6 mm) over the entire surface. The display is rolled with green pile yarn.
The stripes were formed at intervals of 5 cm using the red pile yarn as a high cut.

In the artificial turf for a walking path according to the second embodiment, even when the user steps on the trousers while wearing work shoes, the hardened feeling of the pile yarn is transmitted to the stripe display portion, which is useful for displaying a danger area or a safety display at a construction site or the like. It became something.

[0015]

[Effect of the Invention] In the present invention, two kinds of original pile yarns are used, one of which is a high cut pile and the other of which is a roll pile, which are alternately woven into the base fabric in the gage direction to change the pile shape. The part that has been used becomes the display part. In other words, one of the adjacent pile yarns of a different color is a high cut and the other is a roll loop, so that the hue of the high cut pile yarn appears on the surface at that point, and the hues of the points are arranged. Thus, a display unit is formed. In the present invention, since the pile yarn is used, the display unit can be made inexpensive and durable without using a coloring agent. In addition, if the roll pile yarn gives the uprightness of the high cut pile yarn and gives a difference in the rigidity of the pile yarn, the artificial turf is useful for a walk path in which the display unit can be recognized by the tactile sensation. Was made.
