The resident artificial turf has become a symbol of modern sports facilities in China. In recent years, with the vigorous development of sports and mass leisure sports in the country. From the school stadiums and kindergartens to the leisure places in the community, the country has formed an increasingly new trend.
Sense of the ball — Whether the trajectory on which the ball is running meets the requirements of the competition. The artificial turf is used to make the most important sense of the foot - the feeling of the athlete running on it.
At present, in the absence of a unified national industry norm, there is a lack of necessary under standing of sport Artificial Turf Carpet on the market. It is increasingly necessary to properly understand and evaluate artificial turf.
And meet environmental requirements. According to the artificial grass for football Management and Evaluation edited by Professor Li Shuqing, the artificial turf can be evaluated from the following aspects: the artificial turf produced by each country must conform to the industrial specifications of each country before the entrance.
1. Specifications
The longest straw is currently 60mm mainly used for professional football fields and the length of grass. In principle, the longer the better. The most common length of grass used in football fields is about 30mm.
2. Appearance
Whether the grass is soft and the color is natural. How does it look?
3. Fiber
The price is higher. However, if it is too soft, the main component of the filament which is composed of filaments is polyethylene or polypropylene. The former is softer than the latter. The grass is difficult to stand up and the ball has a low rebound ability. There are two evaluation indexes for fiber filament: number of turns and fiber diameter. The rare number of turns is 5700 dtex, 7600 dtex, 8800 dtex and 10000 dtex, which means that the more the number of turns, the finer the grass, the better the quality. The diameter of the fiber is calculated in μm, typically between 50 and 150 μm. The larger the fiber diameter, the better. The large diameter gives the impression that the grass is thick and wear-resistant. The diameter of the fiber is as small as a thin plastic sheet and is not wear-resistant. The index of fiber filaments is generally difficult to measure, so FIFA generally uses the index of fiber weight.
4. Fiber quality
It is used to ensure that not only the number of fibers in the fiber is correct but also the degree of fiber used.
5. The density of grass
What is the number of cluster heads per meter of grass, there are two angles to evaluate this: first. The football field is generally 130 200, the more cluster heads the better; the second, the woven distance, that is, the line spacing of the grass, is generally 5 10mm, the denser the better.
