The Evolution of Artificial Grass
In the beginning, Astroturf was made from nylon (polyamide) and was in fact basically a thick layer of carpeting. Nylon had the unpleasant tendency to cause ‘burns’ when it came into skin contact, for example, when baseball players had to slide into base. Furthermore, nylon was also a relatively costly material, which meant, at that time, an artificial grass playing field represented a sizable investment.
In the 1980s, the second generation of artificial grass was born for sports made from polypropylene yarn with a 90% sand infill were introduced. Polypropylene was less expensive than nylon. The sand infill was used to stabilize the playing surface, or, in other words, to achieve a more natural ‘ball bounce and roll’ for tennis and hockey, and it also made the artificial grass system even cheaper. The disadvantage of sand was that it acted like sandpaper on the skin when players had to make a sliding tackle and it meant that these surfaces were not suitable for football.
At the end of the 1990s, the third generation of artificial grass playing surfaces was developed for field contact sports such as soccer, American football and rugby. The difference from artificial grass pitches laid the 1980s was that players could make sliding tackles without burning or grazing their skin. This was mainly due to the use of polyethylene as a raw material for the artificial grass fibers and an infill consisting of granulated rubber instead of sand, or a layered combination of both.
Artificial Grass Backing
The backing of artificial grass is the stabilizing fabrics in which the fibers are stitched and provide stability to the turf. Normally there is the primary backing and a secondary backing. The primary backing materials typically are woven or non-woven fabric in one of more layers (usually two) made of strong polyester or polypropylene. The fibers are tufted into the backing in rows. This artificial grass in proves to be highly useful. Secondary backings are designed to hold the turf in permanently by creating a strong turf bind so that the turfs will not come loose. This backing is usually a urethane backing but can be other types as well.
There are three types of artificial grass backing available:
- Hole Punched Backing
- Felt Like Backing
- 100% Permeable
Thatch is the curly yarn made from polypropylene that is woven into the turf that creates a look of dead grass. It can be brown, green or tan. We offer both thatched and non-thatched turf options.
The most common infill for landscape artificial grass is silica sand. It can be angular or rounded. The rounded sand is superior because it has better drainage characteristics. It comes in various sizes but must be able to go the the bottom of the turf.
