Description

TECHNICAL FIELD [0001] The present invention relates to an artificial turf structure which is harmless to human body,

The present invention relates to an artificial turf structure which is harmless to a human body, and more particularly, to an artificial turf structure which is harmless to a human body, more specifically, a plurality of protrusions are provided along the longitudinal direction of artificial turf fibers to prevent the artificial turf fibers from being detached from the fore- Artificial turf structure.

In general, a grass court is used to prevent injury to the player. In recent years, demand for grass fields has been increasing due to the expansion of leisure activities. These grass fields are produced by reproducing natural grass or by applying artificial grass.

The natural grass field is not only inefficient because it is only about 40 to 50 days in a year in the long winter season like our country, but it also damages natural turf after exercise in a natural grass field. I was forced to limit the number of days it was used.

In addition, as the roots of natural grass are damaged during use, the natural grass is frequently killed, so careful attention must be paid to the care of lawns such as spraying seeds or watering water periodically.

Therefore, a general grass field is formed using artificial grass fibers. Artificial grass fields are less damaged than natural grass, but when used for a long time, artificial grass fibers are damaged and need to be periodically maintained, managed and replaced do. Typical artificial turf fibers have a lifetime of 8 to 10 years. When they reach that period, artificial turf should be removed from the grass field and new artificial turf should be constructed.

These artificial grasses are filled with rubber chips or reclaimed rubber chips using waste tires in order to have a buffer effect of natural grass. The harmfulness generated from such waste tire rubber chips or reclaimed rubber chips appears as a social issue . Since the waste tire rubber chip is black, it absorbs sunlight and raises the temperature of the ballpark, which can deteriorate the running environment. In addition, when the temperature exceeds 30 ° C in the summer, a smell is generated in the rubber chip, and the rubber chip, which is melted in the hot geothermal heat, sticks to the rubber chip.

In addition, due to the process characteristic of producing a waste tire chip by pulverization, the pulverized chip may be crushed during long-term use, causing dust to contaminate the periphery. In Europe, it is reported that harmful substances such as heavy metals, polynuclear aromatic hydrocarbons, toluene, benzene and nitrosamine have been detected in artificial turf.

Korean Patent No. 10-1138004, for example, discloses a method for constructing artificial turf, comprising the steps of laying artificial turf and laying a cushioning member made of synthetic resin on a flat ground surface, The artificial turf is installed on the upper part of the gravel layer so that the ball is constantly and excellently bound to the artificial turf when the ball is dropped, thereby minimizing the possibility of injury of the player due to warping or the like.

However, the present invention merely suggests only a portion for laying a buffer member made of a synthetic resin into which a fiber yarn entangled in three dimensions between upper and lower nonwoven fabric filtration layers is placed on the upper surface of a flat ground, There was a problem that was not described.

In addition, since the invention does not describe artificial turf at all, there has been a problem that artificial turf can be damaged quickly in case of a heavy sports game. As the artificial turf is used for a long time, And there was a problem of non-appreciation such as the effect of artificial turf being reduced originally.
