いものとなっている。2. Description of the Related Art Conventionally, as artificial turf made of thermoplastic resin which can be connected to each other, many artificial turf molded by injection molding are commercially available. These artificial grasses are easy to care for and relatively inexpensive, so they are rapidly becoming popular around home entrances and verandas. However, because of the same shape, which is both an advantage and a disadvantage of injection molding,
When used in conjunction, it has to be monotonous and lacks luxury.

を伴う。In order to improve the point that the appearance is monotonous and the sense of quality is poor, it is conceivable to apply a pattern to the surface of the artificial turf. The pattern by changing the color,
Attempts have already been made, and marble-like flow patterns and granite-like spot patterns are known. However, these patterns are, unfortunately, products of chance that we left to emerge,
Problems remain in reproducibility. In an artificial turf having no planar shape such as a tile, the color pattern is not conspicuous and has a poor sense of quality. Furthermore, if it is attempted to create a design as designed by a molding die, the structure of the die becomes complicated, and it is difficult to remove the product from the die during molding.

The problem was solved by providing an artificial turf that features. The pattern was developed by changing the degree of bending at the tip of the turf after injection molding. Specifically, by pressing a heating plate having an uneven pattern on the surface of the molded body in a uniform state without a pattern at the time of taking out from the mold, the degree of bending at the tip is changed, and a desired pattern is formed. Obtainable.

を作ることができる。The artificial turf of the present invention can be manufactured by the following method. For example, FIG. 1 or FIG.
In order to obtain the artificial turf having the pattern shown in FIG. 1, molding is performed using a heating plate shown in FIG. The heating plate is provided with a groove having a width of 30 mm and a depth of 5 mm at a position corresponding to a diagonal line. The temperature condition of the heating plate is determined by setting the melting point of the thermoplastic resin to M
p, when the temperature of the heating plate is expressed as T, Mp−20 ° C. ≦
T ≦ Mp + 10 ° C. is preferred. Mp-10 ° C ≦ T ≦ Mp
+ 5 ° C. is more preferred. For blends of different resins, use the Mp of the resin with the lower melting point. The heating plate heated under the above temperature conditions is applied to the surface of the injection-molded unit in a time of 2 to 6 seconds at a time, divided into several times, preferably divided into 2 to 6 times, and gradually stronger. By pressing, the unevenness of the heating plate is transferred to the surface of the single body, thereby causing a difference in the bending state of the surface, and an artificial turf having a pattern can be produced. Also, for the first few times, by using a heating plate having a smooth surface and subsequently using the heating plate shown in FIG. 10, an artificial turf having a more luxurious pattern can be produced.

Example 1 350 tons of a raw material obtained by mixing 60 parts by weight of an ethylene-vinyl acetate copolymer (containing 10% vinyl acetate), 40 parts by weight of polyethylene, 2 parts by weight of a slip agent master batch, and 0.5 part by weight of a pigment were injected. It was put into a molding machine and molded using an artificial turf mold to obtain a single molded product having a 30 cm square connecting portion. Subsequently, it has an uneven pattern shown in FIG.
The surface of the molded product was pressed five times for 5 seconds each with a heating plate heated to 100 ° C. to obtain artificial turf. The artificial turf thus obtained has a beautiful cross pattern (1 is a convex portion, 2 is a concave portion) as shown in FIG. Can be expected to be used.
