FAQ

  • BackingBacking

    The backing of the synthetic turf carpet provides the strength, dimensional stability and tuftlock of the system.

  • BaseBase

    The advantage of a well-planned base is that it does not have to be rebuilt each time the turf itself is replaced. A good, stable and suitable base is extremely important for the overall quality of the pitch and its lifespan. A well-constructed base consists in most cases of a porous, drained sub-structure (except in countries with hot climates). The base provides stability, drainage and evenness of the field.

  • CreepCreep

    Creep is a phenomena present in viscoelatic materials like polypropylene and polyethylene. It is defined as the tendency of a solid material to slowly deform permanently under the influence of stress.

  • DenierDenier

    Denier is a unit that measures the linear mass density of yarn. It stands for the mass in grams per 9.000 meters.

  • DrainageDrainage

    Most sports fields have a drainage system. This consist of underground pipes that drain off surplus water as soon as the groundwater level rises, preventing the artificial pitch from flooding.

  • DtexDtex

    Dtex stands for decitex and is a measurement that is used in the textile industry for measuring yarn. It is equal to 9/10th of a Denier.

  • E-LayerE-Layer

    An E-layer is an elastic foam that provides a synthetic turf system with its ball rebound, comfort and constant performance, shock absorption, energy restitution, foot stability and deformation behaviour.

  • ExtrusionExtrusion

    Extrusion is the process in which the yarn is drawn through a die of the desired cross-section.

  • Fiber thicknessFiber thickness

    Fibre thickness measures thickness of the edge of a fibre and is measured in microns.

  • Fiber widthFiber width

    Fibre width measures the width of the yarn in mm. This information can be useful for studying the durability or the vertical recovery of a fibre.

  • Gas fadingGas fading

    The discolouring of polyethylene is a phenomenon that is well-known in the polymer industry. It is also described as yellowing, pinking or gas fading. The changes in colour in the material are generally the result of the auto-oxidation of phenolic antioxidants in the basic polymer used. These phenolic antioxidants are added to the resin by the producer to protect and stabilize the polymer during processing and use. The change in the colour of the polymer is strictly cosmetic and does not affect physical properties.

  • GeotextileGeotextile

    The term geotextile is short for geosynthetic textile. Geotextile serves the stabilization surface for proportional distribution of pressure and protection of the shockpad.

  • InfillInfill

    A combination of sand and rubber granules is used as infill for most synthetic fields. Infill provides the synthetic turf field with ball rebound, energy restitution, prevention of injuries, flame resistance, grip, stability and low sliding resistance.

  • KdKKdK

    KdK is the process in which the yarn is knitted into socks and after that heated up so that they can be unravelled and wound back onto the bobbins. This gives the fibre a curl, with the purpose of giving the field a non-directional function. In this way, the fibres retain their resilience and also offer excellent capabilities to retain water.

  • Line-dancingLine-dancing

    Under the influence of constant stress, the backing slowly starts to deform permanently and the carpet starts to grow. This effect is caused by viscoelastic creep in the backing.

  • Lisport testLisport test

    The Lisport test is used to obtain an indication of the durability of turf blades in a specific turf construction. The Lisport test gives a visual indication of how a synthetic turf system will age in time as a result of usage of the pitch.

  • MicronsMicrons

    Micron stands for micrometre and is a unit of measurement that is also used in the turf industry.

  • Pile heightPile height
    Pile height is measured in millimeters and is the height of the pile above the primary backing.
  • Pile weightPile weight

    Pile weight is the total weight of the yarn in the synthetic turf. It is often measured in m2.

  • PlyPly

    A ply is two or more strands of yarn that are twisted together.

  • PolyethylenePolyethylene

    Polyethylene, often abbreviated to PE, is a type of thermoplastic that is also used in synthetic turf.

  • PolymerPolymer

    Polymer is a molecule that consists of several identical or semi-identical parts that are joined together. Polyehtylene and Polypropylene are examples of polymers

  • PolypropylenePolypropylene

    Polypropylene, often abbreviates to PP, is a type of thermoplastic that is also used in synthetic turf.

  • Stitch rateStitch rate

    The stitch rate can be defined as the number of times per inch a stitch occurs.

  • Synthetic turfSynthetic turf

    The synthetic turf is the most conspicuous part of a synthetic pitch. The carpet and the infill together determine to a large extent the playing properties of the pitch: for example, the number of player-field and player-ball interactions, such as sliding tackles, the grip of the boots and the roll of the ball. The synthetic turf carpet is made of a backing and synthetic turf blades. The blades are punched through the backing by a machine known as a tufter.

  • Tuft bindTuft bind

    The tuft bind measures the strength of the attached loop of yarn in the backing of the synthetic turf.

  • Tuft gaugeTuft gauge

    The tuft gauge is the distance between the needles in the tufting process.

  • TuftingTufting

    Tufting is the process of textile weaving in which a thread is inserted into the primary base.

  • Turf bladesTurf blades

    Turf blades are the synthetic fibres who give the look and feel to a synthetic turf field

  • UV-stabilityUV-stability

    It is well known that plastics in general and polyolefins in the case of synthetic turf are sensitive to degradation when exposed to sunlight. This is called photo-degradation, which is a process that generally results in the polymer chains in the polymer/product breaking down. This circular chain reaction will accelerate unless stabilizers are added to the polymer. Ultimately photo-degradation causes cracking, chalking, colour changes and loss of physical properties.

  • Weather-O-Meter (WOM)Weather-O-Meter (WOM)

    This machine simulates accelerated outdoor exposure and, fitted with a Xenon light source, provides very realistic data. The WOM exposes the turf blades to artificial sunlight and rain in cycles. Every 1000 cycles the tensile strength of the turf blades is measured, and the possible reduction in tensile strength calculated.
