た。2. Description of the Related Art Traditional tatami mats, which can be said to be the basis of Japanese dwelling culture, have traditionally been made from natural rush. This natural grass is
Although it has a cool feeling in summer, a warm feeling in winter, and an excellent texture, it is a natural fiber mainly composed of cellulose, so it has poor durability such as abrasion resistance, and mold and rot due to water absorption and moisture absorption. Moreover, there was a problem such as discoloration due to direct sunlight. Also, due to the recent changes in the working environment, the production is heavy labor accompanied by work in the mud, so successors are not grown up and it is difficult to maintain the production volume. Therefore, Korea
Imports from China have also become popular.
However, as the supply base expands in this way, problems arise in maintaining quality, and supply instability due to the influence of the weather and fluctuations in prices due to it also cause major defects as industrial materials. Met.

い。Against this background, many grass substitutes have been commercialized in recent years. For example, artificial grass made of polypropylene resin independent linear foam has been commercialized for 20 to 30 years. However, although it has a long history of being used only for tatami mats and mats for judo, it has not yet become widespread as a tatami mat.

ツキ感がつよいなど、人工的感触のつよいものでしかな
かった。The former artificial grass is unsatisfactory in terms of appearance, texture and physical properties. For example, light reflection is strong and the surface is too shiny. Since it was uniform, it had only a strong artificial feel, such as a slimy feel and a sticky feel.

面で満足できるものではなかった。Further, the latter artificial grass produced by the method disclosed in Japanese Patent Laid-Open No. 1-92443 has a long manufacturing process, and since a high-density tape-like material is passed through a heated narrow space, an unfused portion is inevitable. In addition to the disadvantages that occur naturally, it is not possible to give the color depth of the appearance to fuse the film, and in the end, it is more satisfactory in appearance, texture and physical properties than natural grass. Was not.

The artificial grass of the present invention is characterized in that it is a linear body coated with a resin coating film, and the artificial grass of the present invention has a foamed resin coated inner layer in which a film made of a thermoplastic resin is randomly folded. The artificial grass of the present invention is also characterized by being a linear body coated with a film, and the artificial grass of the present invention further comprises an inner layer in which a film made of a thermoplastic resin is randomly folded, And a linear body covered with a coating film of a thermoplastic resin different from.

If a linear body whose outer periphery is covered with a specific resin coating,
Surprisingly, it was completed by investigating that it is possible to obtain a product with excellent appearance and properties without artificial feeling such as shine and slime that closely resemble natural grass.

張った部分も存在するものである。That is, the artificial grass of the present invention is a linear body in which the film is randomly folded in an inner layer and the inner layer is covered with a coating film of molten resin. The thickness of the resin coating film of the present invention is inevitably thick or thin when the melt coating is performed because the flow of the molten resin is influenced by the folded shape and the packing density of the film forming the inner layer. Occurs and a uniform coating film is not formed. That is, the coating film is formed in a concavo-convex shape depending on the folded shape and density of the film of the inner layer, and the folded shape forms the irregular cross section of the artificial grass of the present invention. Here, the irregular shape is a substantially circular shape, but has irregular irregularities, for example, an irregular shape such as drawing a circle with a freehand, and some flat parts, and angular distortion. There are also parts.

For example, olefin resins such as polyethylene, polypropylene, and ethylene-propylene copolymer, thermoplastic resins such as vinyl chloride, polyamide, acrylic resin, and mixtures thereof can be used, but they are flexible, elastic, and thin. A highly durable polyolefin-based resin is preferably used. When a coating film made of a foamed resin is used as the resin coating film, it is possible to provide an artificial grass that is free from the above-mentioned artificial feel, is flexible, and has an excellent appearance.

Those having a thickness in the range of up to 50 μm can impart tension and moderate elasticity that closely resemble natural grass. As the resin forming the film, the thermoplastic resin forming the resin coating film can be used, but a film made of a resin different from the resin coating film can also be used.

と、それぞれの機能を付加することができる。In the present invention, the use of different thermoplastic resins for the internal layer and the coating film has the advantage that various surface characteristics and functions can be freely set and the texture can be changed. There is. For example, when a resin having an affinity for a dye or a pigment is used as the coating resin, it is possible to provide a deep-color artificial grass that is rich in color change. Further, by using a hydrophilic resin, it is possible to provide an artificial grass having an excellent cool sensation, and in addition, if a resin containing various functional agents such as an insect repellent, a water repellent, a thermochromic dye, a fungicide, is used, Each function can be added.

It has a structure. According to this device, there is an advantage that the resin can be supplied in a uniform amount by an extruder, and after the resin is applied, the cross-sectional shape of the artificial grass to be produced can be freely changed by the shape of the die. You can also The artificial rush that has come out of the mouthpiece is rapidly cooled with a cooling agent such as water to be solidified.

の範囲で使用される。When a foamed resin is used as the resin coating film, examples of the foaming agent to be added to the resin include organic foaming agents such as azodicarbonamide, azobisisobitylonitrile, and trihydrazinotriazine. Inorganic foaming agents such as calcium carbonate, ammonium bicarbonate, and peroxides are used, and these foaming agents are appropriately used according to the melting point of the above-mentioned thermoplastic resin as the main material. The mixing amount of the foaming agent is determined by the gas generation amount of the foaming agent, the expansion ratio of the product, etc., but in the artificial grass of the present invention, the expansion ratio is preferably about 2 to 3 times, Is preferably used in the range of about 0.3 to 1.0% by weight with respect to the resin.

しく悪くなる傾向がある。In addition, the addition of an inorganic filler to such a thermoplastic resin is effective in improving the texture of the artificial grass. As such an inorganic filler, calcium carbonate,
Titanium oxide, potassium chloride, magnesium hydroxide, magnesium stearate, magnesium carbonate, talc, silica-based filler and the like can be used, and among these, calcium carbonate is particularly preferable for the artificial grass of the present invention. . The amount of such an inorganic filler mixed varies depending on the desired feel, but is preferably 2 to 40% by weight, preferably 7 to 30% by weight. When the amount is less than 2% by weight, shininess and unevenness are severe, and when the amount is 40% by weight or more, it is difficult to form a linear form, and the color developability tends to be remarkably deteriorated.
