What is the way to identify the artificial turf is good or bad

19/10/2017

  1.Specifications

  The length of the grass silk. Soccer field in principle, the longer the better (outside the leisure field), the longest grass is 60mm, mainly for professional football field, the most common for the football field of grass silk length of about 30-50mm or so.

  2. Appearance

  Whether the color is natural, the softness of the grass is good, the appearance of how the feeling.

  3. The density of grass silk

  From the two angles to evaluate: First, from the back of the lawn to see the number of straw needle, the number of needle per straw grass wire the more the better; second, from the back of the lawn to see the line spacing, that is, the line of silk wire spacing, The better.

  4. Fiber quality

  The higher the quality of the unit, the better the quality of the grass. The weight of the silk fibers is expressed in terms of fineness, defined as Dtex, and 1 gram is defined as 1Dtex per 10,000 m of fiber mass. The greater the weight of the silk fiber, the more the thicker the grass silk, the greater the weight of the silk fiber, the stronger the resistance to wear, the greater the weight of the grass fiber, the longer the service life. However, due to the greater the weight of the grass seed fiber, the higher the cost, according to the age of the athletes, the use of frequency selection suitable for the weight of the grass, large sports venues recommended the use of more than 11000Dtex heavier grass silk weaving lawn.

  5. Grass silk fiber

  Lawn of the finished product is made of fiber, the main component of fiber is polyethylene, nylon, polypropylene and so on. The first two are more soft than the latter, the price is higher. However, if too soft, grass silk is difficult to stand up (here refers to the movement of grass), the ball's rebound ability is low. Fibers have two evaluation indicators: grass fineness and fiber diameter. Common movement of grass silk are 5700,7600,8800 and 10000, that is to say grass grass grass fineness of the higher quality the better, the number of grass roots per straw more grass silk more fine, the better the quality. The diameter of the fiber is calculated in terms of μm, typically between 50 and 150 μm. The greater the diameter of the fiber the better the diameter of the big feeling is thick grass silk, wear resistance, the diameter of the fiber as small as a thin plastic sheet, not wearable. Fiber yarn indicators are generally difficult to measure, so FIFA generally use fiber weight indicators.

  6. Other aspects

  Artificial turf is used to use or to beautify the living environment, so the most important foot feel and color quality is considered the first element, if it is sports turf to consider the athletes in the above run feeling, Whether the above track is in line with the requirements of the competition.
