How to identify the pros and cons of artificial turf?
1., the appearance of natural colors, grass silk soft degree is good, how the appearance of feeling?. 2. specification length of straw silk. The longer the football field is, the longer the lawn is, and the longest grass is 60mm, which is mainly used in professional football fields, and the grass filament length used in the football field is about 30-50mm. 3. yarn density from two angles: first, look at the evaluation of yarn needle number from the back lawn, needle number per meter of grass is better; second, look at the spacing from the lawn grass is back, line spacing, spacing as close as possible.
Other aspects of artificial turf is used or is to beautify the living environment, so the most important color Juegan and quality is the first element to consider, if it is to consider the sports turf athletes run in the above sense, the ball -- ball on top of the trajectory of compliance with the requirements of competition.
The better the quality of fiber is, the better the grass is. The fiber weight of the straw fiber is defined by Dtex. It is defined as "1 grams per 10000 meters fiber" and is called "1Dtex". The greater the weight of the straw fiber, the stronger the grass fiber, the greater the weight of the grass silk fiber, the stronger the resistance to abrasion, and the greater the weight of the grass fiber, the longer the service life. But because the grass seedling fiber pound greater cost is higher, according to age, the movement of the frequency of use in choosing suitable grass seedlings pounds, a stadium that suggested the use of more than 11000Dtex pounds of grass silk weaving lawn.
The finished product of straw silk fiber lawn is made of fiber yarn. The main ingredients of fiber yarn are polyethylene, nylon, polypropylene and so on. The first two are softer than the latter, and the price is higher. But, if too soft, the grass is difficult to stand up (here refers to the movement of grass), the ball rebound ability is low. There are two evaluation indexes of fiber yarn: Grass size and fiber diameter. The common sports grass silk has 5700, 7600, 8800 and 10000, that is to say, the grass silk grass size is higher, the quality is better, each cluster grass silk root number is more, the grass silk is more fine, the quality is better. The diameter of the fiber is calculated by m, usually between 50 and 150 m. The larger the diameter of the fiber, the better the diameter, giving the impression that the grass thick silk, wear resistance, fiber diameter is small, as if very thin plastic film, not wear-resistant. The index of fiber yarn is generally difficult to measure, so FIFA generally uses fiber weight indicators.
