In addition, natural grass requires careful attention to management, such as watering, rehabilitation due to damage.

 Therefore, the construction area of artificial turf field, which is more utilized than natural grass field, is expanding rapidly. In the artificial turf mat required for the construction of artificial turf, it is technically important to improve the pulling force of the artificial mother and the drainage of the mat. In general, artificial grass mat weaves artificial wool using pile yarns on bubble paper, and piles the bottom surface of knotted bubble paper with SBR latex, polyurethane (PU), polyvinyl chloride (PE), etc. Use ways to increase your pull.

The conventional artificial turf mat manufactured by the above-described method has a mono structure or a double (mono + crimp) structure, and when the artificial turf mat is constructed in the playground, due to the phenomenon of pile yarn lying in one or several directions The straightness of the ball is reduced, the control is changed according to the direction of the ball rolling, the cushioning is not only poor, and there is a problem of ankle injury. The method of applying the entire surface with urethane (PU) and polyvinyl chloride (PE), etc., has a problem in that the pull-out force of the latex coating is sharply lowered during heavy rainfall.

In the present invention, in order to solve the above problems, the artificial turf mat is composed of the first file and the third file in the form of a straight hair, the second file and the fourth file in the form of a crimp, and the first and second files are the same needle. Weaving tufts at the same time (needle A), tufting weaving the third and fourth piles at the same needle (needle B), lengthening the weaving depth of needle A when tufting weaving, and weaving depth of needle B When the end of the pile yarn is cut at the same time as weaving it to be shorter than A, the first pile and the third pile in the form of straight hair maintain the cutting length, and the second pile and the fourth pile of the crimp yarn are restored to their original lengths, respectively. The pile yarn was formed to form a quadruple structure to play each role. That is, the first file is smoothly changed in all directions even after a small impact during exercise, and then the original file is restored. The second file is formed between the first files, and the first file serves as a support for the first file to be restored. By raising the density of the lower part of the pile as much as possible, supporting the first pile and the third pile, and acting as a shock absorber and support, not only solves the above problems but also allows the construction of the playground without laying silica sand or fillers. A method for manufacturing artificial turf mats having pile pile yarns has been developed.

In addition, when weaving lining bubble paper, we composed alternating weaving section and drainage section in width direction, and improved the durability of artificial turf mat by selecting foam paper with good drainage and drawing power.
