Artificial grass originated in the United States 50 years ago, initially used in baseball fields, and then quickly promoted in other sports fields. As the world's largest sports, football has the huge space, undoubtedly become an important battlefield of artificial grass. The development of football artificial grass has gone through four stages so far.
The first generation of football artificial grass is made of PA (Nylon) material; its wear resistant and weather resistant is good. With the similar appearance to carpet, it has no elastic layer and doesn't infill quartz sand, the surface is hard and has poor elasticity which is easy to scratch the skin. What's more, the price is expensive.
The second generation of football artificial grass is made of PP (Polypropylene) material. Compared with Nylon, the grass yarn is a little softer and has better plasticity; the wear resistant is less than Nylon. Infill the quartz sand and without elastic layer, the price is more affordable. But it is also easy to scratch the skin.
The third generation of artificial grass is made of PE which is also the most commonly used grass yarn raw material at this stage and the emergence of mixed PP + PE, PP + PA, PE + PA, mixed with straight yarns and curled yarns, and different shapes of monofilament grass and other forms. The grass yarn of 3rd generation grass is soft and has good wear resistance, the price is affordable. With quartz sand and rubber granules filled, in terms of appearance and sports performance which has been very similar to the real grass.
The fourth generation of football artificial grass is a major innovation based on the traditional artificial turf. It refers to the "non-infill football artificial grass + shockpad" as a combination of non-infill football artificial grass system. VIVATURF firstly proposed this fourth generation of artificial turf concept in the world.
The so-called fourth generation artificial turf, is to abandon the "quartz sand + rubber granules" as a filling materials, and the use of "non-infill football grass + shockpad" approach to achieve the movement and protection of artificial turf. At the present stage of artificial turf market, the fourth generation of artificial grass, whether its touch or movement, fall, slide resistance and ball rolling feedback, is the closest to the natural grass.
