E.g.: Tufting online
Shows you the manufacturing technique used to make artificial turf, which is mostly tufted. For more information on tufting, see the web article at: http: //www.Exelgreen.com/fr/Exelgreen-le-blog-specialise-dans-le-gazon-synthetique/3-la-fabrication-du-gazon-synthetique). It can also be woven or needled.
E.g.: 100% Polyethylene
Provides information on the composition of the yarn and the polymer used in manufacturing.
Pile weight (gr/m2)
Indicates yarn weight only.
E.g.: Two-tone curly monofilament
The structure of the yarn shows the yarn manufacturing process used for artificial turf. There are 2 techniques, monofilament yarns and fibrillated yarns. Monofilament yarn is made of a continuous single strand while fibrillated yarn is a continuous, notched tape to create multiple individual threads.
Thickness of the yarn (µ):
Indicates micron thickness of the yarn used for artificial turf.
Pile height (mm)
Indicates only the pile height in mm. In accordance with regulations covering textile products, a + or - tolerance can be noticed.
Number of tufts per m2
This is the number of stitches to the m². Not to be confused with the number of strands. In fact, a tuft contains several strands of artificial turf.
E.g.: 3/8 ''
This is the distance between two rows of threads. The gauge is calculated in inches, where one inch = 2.54cm. Calculated every 8 or 16 lines of tuft yarn, it indicates the number of needles used in manufacture. 3/8” artificial turf means you have 8 lines of yarn over 7.62 cm, (3 x 2.54) or one thread every 0.95cm.
This is the weight in grams per 10,000 linear metres of thread. So, 5500 dtEx means that the yarn used weighs 5.5kg for 10,000 lm.
GRASS CARPET SPECIFICATION
E.g.: UV-stabilised Fibreglass
Composed of 2 layers, it is generally made of a UV-stabilised woven polypropylene fabric. This primary backing material serves as a support for the artificial turf’s coating.
Coating consists of covering the primary backing material in order to fix the artificial turf yarn. The 2 main coating techniques are latex and polyurethane.
Total weight (gr/m2)
The total weight includes the yarn weight, the weight of the primary backing material and the coating. It is important to know that it is not the total weight of the product that determines the price but the weight of the yarn.
Roll width (m)
E.g.: 1.2 or 4
Indicates the different roll widths available. In accordance with regulations covering textile products, a + or - tolerance can be noticed.
Roll length (m):
Indicates the standard length of a whole roll. In accordance with regulations covering textile products, a + or - tolerance can be noticed.
E.g.: greater than 30 N
Expressed in Newton, it provides information about the peel strength of the artificial turf and carpet strength.
1 Newton = 0.1020 kilogram-force therefore a product whose peel strength is greater than 30 Newton can support over 3 kg of tensile stress.
E.g.: 60L /M2/min tested unballasted
Indicates the amount of water the artificial turf lets in per 1 minute per 1 m². Generally tests are carried out without sand filling on the turf (unballasted).
E.g.: Xenon test: blue 7 grey 4
This test measures the impact of UV light on artificial turf over time. These laboratory tests enable accelerated quality control on materials without having to run 5 and 10 years of external tests.
This test checks the resistance of artificial turf yarn to chlorine. As the polymers used are resistant, there are very few artificial turfs that do not have this resistance.
REACH (Registration, Evaluation and Authorisation of Chemicals)
E.g.: Certified heavy metal- free
REACH is a regulation of the European Parliament and Council of the European Union, adopted on 18th December 2006, which modernised European law on chemicals and established a single integrated system for Registration, Evaluation and Authorisation of chemicals in the European Union.
E.g.: Without filling
Filling means allowing a certain amount of sand to penetrate between the turf fibres to keep the artificial turf blades straight.
