See whether the color is natural, whether the softness of the grass silk is good, and how the appearance feels. Looking at the length of grass silk, in principle, the longer the sports field, the better (recreational field list), the current length of grass silk is 60mm, mainly used for professional football field, common for sports field length of about 30-50mm.
The larger the mass of grass silk in the same unit length, the better the grass silk fiber pound weight is in the unit of thinning, the larger the grass silk fiber pound weight, the stronger the grass silk fiber pound weight, the stronger the wear resistance, the larger the grass seedling fiber pound weight, the longer the service life. However, because the larger the fiber pound weight of grass seedlings, the higher the cost, according to the age of the athletes, the frequency of use to choose the appropriate pound weight of grass seedlings, large sports venues are recommended to choose more than 11000Dtex pounds of grass silk woven lawn.
From two points of view: First, look at the number of threads from the back of the lawn. The more stitches per meter of silk, the better.
artificial turf products are mainly composed of fiber silk, the main components of fiber silk are polyethylene, nylon, polypropylene, etc., the first two are softer than the latter, the price is higher, but if too soft, grass silk is difficult to stand up (here refers to sports grass), the rebound ability of the ball is low, there are two evaluation indexes of fiber silk: Grass size and fiber diameter, that is to say, grass silk grass size higher quality better, each cluster of grass silk root number more grass silk fine, the better quality, the larger the fiber diameter, the better the feeling is that the grass silk thick, wear resistance, small fiber diameter like a very thin plastic sheet, not wear-resistant.
