Most artificial turf main materials use PE grass. Although PA has good abrasion resistance, it is too hard to burn athlete's skin and is mainly used in landscape grass fields. PP has poor abrasion resistance, short field life and narrow application range. PE is soft and has abrasion resistance Good, is the choice of sports contact venues now.
The shape of grass filaments: mesh filament, monofilament
Reticulated wire has a lot of performance in many venues in China. Monofilament has become popular in recent years. Its appearance is closer to natural grass. It has a beautiful appearance and slightly wear resistance.
Lawn height
In the European and American markets, the height of a football lawn is usually 60mm, and the domestic custom height is generally 40-55mm. The higher the height of the grass with the same density, the higher the cost. Meet the use.
The weight of grass
Usually divided into 6600DTEX, 8800DTEX, 9700DTEX, 12000DTEX, 15000DTEX, etc., which represents the weight of grass per 10,000 meters of grass. Generally, football fields use more than 8800DTEX.
Lawn density
The density of 50mm grass height is usually 10500 stitches / square meter, but the density of the lawn is related to the weight and height. The higher the height or the higher the weight, the lower the density can be set. In short, the basic weight of grass silk per square meter is about 1 kg.
Backing method of base fabric
Generally, the adhesive method is styrene-butadiene latex. The higher-end adhesive method is PU adhesive. The difference is that the grass silk pull-out performance of PU adhesive is much higher than that of styrene-butadiene latex. The appearance is bright and the waterproof performance is good. The plastic is formed in one time and has less additives, so it is more environmentally friendly. However, the cost of PU adhesive is high, and the price of the finished product is usually 20% -30% higher than that of the styrene-butadiene latex product.
Base fabric type
It is usually divided into a composite base fabric and a composite mesh three-layer base fabric. The tensile strength of the three-layer base fabric is relatively high.
Needle way
It is usually divided into single-stroke and Z-stroke. Both of the stitching methods can meet the requirements of use, but the zigzag stitching method makes the distribution of grass silk more uniform, and the adhesive force of the back of the grass silk will be higher.
