What does the technical date mean?
Basic Technique Data:
Pile height: the height of the pile (the carpet of yarn on top of the artificial grass backing.), usually measured in millimeter (mm)
Dtex: a manufacturing term relating to artificial grass turf yarn measurement; an abbreviation of Decitex, it is the unit of the linear density of continuous yarn – equal to 0.90 of a denier or 0.10 of a tex.
Stitch rate: number of artificial grass turf stitches per 100cm in line direction.
Gauge: The distance between two adjacent lines, usually using “inch” as unit.
Density: Numbers of stitches per square meters.
Backing: Mostly it means second backing on our website or sample label.
The above technical data just descript some primary characteristics. In these parameters, Pile height, gauge could be easily measured by a common ruler. And density could be calculated by the two parameters as mentioned before. For example, if the gauge of one artificial grass turf is 3/8 inch (means in one meter length there are 105 lines,), stitch rate is 140stitches/m, so the density of this model of artificial grass turf is 14700 stitches/ m2. See the Pictures bellow:
Stitch Rate of Artificial Turf
Gauge of Artificial Turf
The first picture: count how many stitches in 10cm. Can find there are 14 stitches in 10cm that means 140 stitches in 100cm (1m)
The second picture: measure the distance between two lines. It is 3/8inch of that model. That means there are 105 lines in 1m.
So you can calculate the density. It is 140*105=14700 stitches/m2
It is easy to count the stitches but a little difficult to get a gauge data like 3/4inch, 3/8inch or 5/8 inch. In fact, gauge depends on the machine. Many tufter (Artificial grass tufting machine) said they are made in a full range of different gauges, but in practice most factories fixed their specific machine to one gauge and they use different machines to produce artificial grass with different gauges. The common gauges are 3/4inch, 3/8inch, 5/8inch, 3/16inch, 5/32inch and 1/2inch.
What kind of synthetic turf should be used for your applications will be largely decide by the pile height and density. For example, football fields require the artificial grass turf between 30mm-70mm, mostly 50mm, and tennis courts require the artificial turf between 10mm-20mm with high density.
