Woven Artificial Turf With Pile Height Of 5.5 Inches Or 14 Centimeters
NV Michel Van de Wiele has developed a method of cutting off-center to create woven artificial turf with an extra-long pile height, which offers advantages for heavy-use applications and opens up possibilities for combining artificial and natural grass.
TextileWorld.com Special Report
Woven artificial turf is being used more and more, both in sport fields and in landscaping.
The process of weaving brings advantages that are critical to the future growth of this market (See Figure 1):
- upright pile position and reduced pile cost;
- excellent pile fixation owing to the W-weave structures;
- good water infiltration rate;
- ecological advantages and easy recycling; and
- reduced installation costs.
In the normal double-face weaving process for woven artificial grass, two fabrics are woven simultaneously and cut in the middle to obtain two equal products.
Figure 1: Van de Wiele notes that the W-weave structure of woven artificial grass provides excellent pile fixation.
Belgium-based NV Michel Van de Wiele's SRi02 weaving machines weave with lancets up to 5.5 inches or 14 centimeters (cm) so that two artificial grass mats each with 2.75-inch or 7-cm pile height are obtained (See Figure 2).
However, cutting off-center can result in one fabric with extra-long pile length, for example, 5.5 inches or 14 cm (See Figure 3). This woven, extra-long-pile turf can be strongly stabilized with artificial filling such as sand and rubber pellets.
Woven long artificial turf is better adapted to heavy use for a football field than shorter artificial turf. Less maintenance will be required. Maintenance costs will also be reduced compared to tufted turf.
The combination of woven long artificial grass and natural grass is finding its way into the market. The artificial grass reinforces and protects the natural grass. The smooth feel of the natural grass and the resistance added by the woven artificial grass are combined.

Until now, the only commercial solution was to insert the artificial grass tufts into an existing natural grass field.
Weaving long artificial grass offers a new and interesting opportunity for this kind of hybrid grass surface. The combination of natural and artificial grass can be obtained with some additional advantages:
The excellent fixation of the artificial grass is realized from the start by the W-weave structure.
As no coating is needed to obtain the desired pile fixation, the base structure remains permeable and open to water infiltration and root growth through the fabric.
The Van de Wiele SRi02 weaving machines produce woven artificial grass with up to 5.5 inches or 14 cm pile height when cutting off-center. This woven turf can be combined with natural grass by adding 4 to 5 inches (10 to 12 cm) soil or ground substrate and sowing natural grass among the artificial turf.
Figure 3: Cutting off-center on the SRi02 enables weaving of extra-long pile of 5.5 inches or 14 centimeters.
This range of products opens up new possibilities in the market of combined artificial and natural grass. Van de Wiele has developed a strong relationship in this field with the Textile Department of the University of Ghent, Belgium, which has an accredited lab, the European Research Centre for Artificial Turf (ERCAT), for testing of artificial grass.
