How to identify the quality of the artificial lawn

Artificial Turf is mainly composed of three parts: grass silk, backcloth and back glue. Among them, the quality of artificial turf is one of the important standards to measure the quality of artificial turf. Today we will look at the technical indicators of artificial turf grass and related concepts, and how to distinguish the quality of artificial turf by correctly identifying the turf.
Technical index of straw yarn
The memory property of grass thread refers to the property of grass thread recovering from folded state to upright state after unfolding. The memory of grass silk reflects the quality of grass silk. The better the memory, the better the durability, the more convenient the construction.
Straw weight
DTEX is the standard index of the international fiber industry. That's the weight of the fibers per 10,000 meters, in grams per 10,000 meters. Grass fiber commonly used DTEX specifications are 6000, 6600, 7400, 8800, 10000, 11000, etc. The higher the index, the coarser the fiber, the better the quality.
Denier is also the standard index of the international fiber industry. That is the weight of each 9 km fiber. It is rarely used in the artificial turf industry. You know why.
Cluster density
Tufting density refers to the number of tufting needles per square meter of artificial turf.
Unit: Cluster/square meter = needles per meter X rows per meter.
Cluster density :10500 12600, 21000 26000, 33000 42000, 50400 63000, etc
Straw line height
Grass height is the length of grass from the bottom surface to the top. Generally 10mm, 20mm, 25mm, 30mm, 32mm, 40mm, 50mm and so on.
The pound weight, cluster density and height of straw determine the PE (PP) dosage per square meter of straw, which is called the three elements of PE (PP) dosage.
How to distinguish the quality of artificial turf? There are only five ways to distinguish the quality of artificial turf. Learn quickly and choose the right product easily.
Weeding silk
The pull-out rate of grass silk of artificial lawn is one of the most important technical indexes of lawn, which can be measured by pulling grass silk. Grab a bunch of grass with your fingers and pull it out. The ones that don't come out are usually the best; Occasionally can be pulled up, and good quality; If you pull a lot of grass without straining, it's definitely poor quality.
Straw thread
When we touch the grass with our hands, we should see if the grass is soft and comfortable. It is generally accepted that soft, comfortable lawns are best. But in fact, if the grass is too soft, it's the worst. You know, artificial turf is used with feet in everyday use. If it is too soft, the grass is difficult to stand up and has poor rebound performance; If it is too hard, grass and aging that are easily snapped off. Therefore, according to the needs of the site, choose the appropriate hardness.
Look at the bottom and back of the artificial turf
If the back of the lawn is black and looks a bit like linoleum, it is the common styrene butadiene adhesive; If it's green and looks like leather, it's premium SPU back glue. SPU rubber back artificial turf adult with 80% of the force can not pull out, butadiene rubber back more or less can pull out, this is the most obvious difference between the two kinds of rubber back quality.
Observe the shape of the artificial turf
There are many shapes of grass silk, such as U shape, M shape, diamond shape, with stem, without stem and so on. The wider the grass, the more material you use. If the stalk is added to the straw, it will be more upright and elastic. Of course, it will cost more. This kind of artificial turf is usually more expensive.
Pressed straw yarn
Lay the Artificial Grass flat on a table and press it down with the palm of your hand. If the grass fiber can bounce back to its original state after letting go of the palm, it indicates that the artificial turf grass fiber has good elasticity and toughness, and the faster the recovery, the better the quality; It is also possible to observe the resilience of artificial turf by pressing heavy objects on it for several days or more and then drying it in the sun for two days.
