Basic knowledge about artificial grass

Artificial turf is mainly composed of three parts: grass fiber, bottom cloth, back glue.

And the quality of the grass is one of the important criteria to measure the quality of artificial turf. Let’s learn about the technical indicators and related concepts?of the grass fiber, and how can you discern?artificial turf is good or bad by correctly identifying the grass fiber.

Dtex:

DTEX is a standard index in the international fiber industry.?That is, gram weight number of root fiber per 10,000 meters, unit: gram / 10,000 meters, grass silk commonly used DTEX specifications are: 6000, 6600, 7400, 8800 10000, 11000, etc., the higher the index, the coarser the fiber, the better the quality.

Density:

Tufting density refers to the number of stitches?per square meter of artificial turf.

Unit: stitches/square meter = number of needles per meter X number of rows per meter.

Commonly used density?specifications are: 10500, 12600, 21000, 26000, 33000, 42000, 50400, 63000, etc.

Gauge:

Number of rows per meter. Commonly used gauge: 3/16=210stitches in 1 meter; 3/8=105stitches in 1 meter; 5/8=64stitches in 1 meter.

Pile height:

Commonly used?pile height: 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm.

Types of turf:

4 major artificial turf: Sports turf/ Landscape turf/ Putting green/ Project turf.

Pound weight, tufted density and grass height determine the amount of PE (PP) per square metre of grass silk, known as the three elements of PE (PP) use.

And how to?discern the quality of the artificial turf? You need only 4 steps, Let us go:

1.Pulling out the grass from the backing; the pull-out strength is a very important technology parameters of the artificial turf. Grab a tuft of grass silk with your fingers and pull it out. The one that can't pull it out is generally the best;?If a lot of grass is pulled out without much effort, then its quality must be relatively poor.

2.Touching the grass fiber; When we run our hands over the grass, we should fell if it is soft and comfortable. Maybe most people think that the best artificial should have the softest fiber,but in fact if the grass fiber is too soft, it will be worst. Artificial turf is used daily with feet, if too soft, grass silk is difficult to stand up with poor rebound performance;?If it is too hard, the grass silk will break and age easily. So?we should?according to the needs of the site to choose suitable hardness.

3.Observe the shape of the grass fiber in the artificial lawn. There are so many shapes about grass fiber, such as U-shape, S-shape, Diamond shape, W-shape, reinforced turf grass and so on. The wider the grass, the more material used. The reinforced turf grass fiber with strong upright and rebound resilience?will be more expensive.

4.Press the grass. Lay the turf on the table and press the grass with your hands, If the grass fiber can bounce back to the original state obviously after loosening the palm, it shows that the artificial lawn grass fiber has good elasticity and toughness, the faster the recovery, the better the quality;?Artificial turf can also be weighed down for a few days or more, and then left in the sun for some?days to see how well the turf recovers.
