As the first company, in 2003, Royal Grass® originally developed and launched artificial grass for use in gardens, public parks, roof terraces and other landscaping applications with the objective of making it as indistinguishable as possible from natural grass.
The high quality of Royal Grass® is based on the developments in fiber technology that were first used in the third generation of artificial grass playing fields:
- High-quality, specially selected raw materials that had already proven themselves in practical applications.
- UV stability and colour-fastness so that the turf did not discolour.
- Safety: no heavy metals, such as lead and zinc, or other substances in the raw materials, which could put users at risk.
- Softness: fibers on which even professional footballers could safely make sliding tackles.
In 2005, Landscape Solutions developed the V-shaped fiber in close collaboration with the R&D department at Ten Cate. The V-shaped fiber keeps the blades of grass upright for a longer period of time, making Royal Grass® artificial grass suitable for more intensive use than artificial grasses that do not incorporate this technology. The shape of this fiber is copied from natural grass, the source of inspiration for Landscape Solutions.
Royal Grass® is developed and produced in the Netherlands. All V-shaped fibers are produced at Ten Cate and the production of the artificial grass takes place in Genemuiden, the Netherlands. Royal Grass® is proud to carry the ‘Powered by Ten Cate’ label.
HOW DETERMINE QUALITY OF ARTIFICIAL GRASS?
That is a difficult question to answer because there are so many characteristics we have to consider. If we look at the general aspects of artificial grass we believe that the North-European suppliers have a good quality standard. That means, the fibers can stand use and will stay green over years. The main reason for you to choose artificial grass is to have the benefits of a low maintenance, beautiful lawn.
The colour, thickness and the height of the products can differ per product and manufacturer and it is for you to determine which of these you prefer.
If we speak about quality you have to consider that artificial grass products have one thing in common, it will flatten after a period of use. The shape of the fiber is very important in the ‘wear and tear behaviour’.
A flat fiber will feel wonderfully soft and looks beautiful when its new, but you will be disappointed after a while when the “grassy-feeling” has disappeared and been replaced by the flattening of your lawn. Royal Grass® has an unique and patented V-shape fiber. This helps to keep the fiber upright for a longer time and allows for each blade to mimic real grass effectively. Besides this advantage you will also love the look and feel of it.
FIBRILLATED OR MONOFILAMENT
Artificial grass fibers come in two types: fibrillated and monofilament. When producing fibrillated fibers, the plastic is pressed through an extruder head like a thin film (similar to videotape). Small notches are then made in this film. When the film is pulled apart, a honeycomb structure is formed. The wide film is spun around until a strong, rounded fiber is formed. The downside to fibrillated fibers is that they do not look natural. Over time, the notches split further and the product takes on a more natural appearance. This type of fiber is often less expensive and therefore used extensively for sports venues or public playgrounds.
Royal Grass® artificial grass is made from monofilament fibers that are pressed through the extruder head as ready-to-use fibers (similar to spaghetti). Multiple fibers are then combined and coiled to produce a bundle that forms the grass pile. Monofilament fibers generally have a more natural appearance. The level of flexibility, softness and wear resistance depends on the proportions (dTex), shape (V-shape & MiNT) and the raw materials used.

WHAT IS DTEX?
DTex expresses the length/mass ratio and is measured as the weight of the fiber per 10,000 metre length. A dTex of, for example, 10,000 means that a fiber with a length of 10,000 metres weighs 1 kilo. The fiber thickness is also important: the thicker a fiber is, the longer it will remain upright. With Royal Grass® artificial grass, the V-shape strengthens the effect of fiber thickness in helping to keep the blades of grass upright.
The total weight of the fibers per square metre in relation to their height also gives an indication of the product quality. Just as with carpet, the denser the weave, the more durable – or resistant to wear – the grass will be. NB: this can negatively impact on the ornamental/decorative function or similarity to natural grass. The reason for this is that thickly woven artificial grass does not automatically make it appear more similar to natural grass! A guideline for the ratio between a natural fiber weight per square metre and the fiber length for artificial grass types with a root zone (also called artificial moss) is a minimum weight of 45 to 60 grams per millimetre fiber length.
THE BACKING OF ARTIFICIAL GRASS
The backing consists of woven fabric, usually made of polypropylene. This material can be reinforced with weft threads or by adding extra layers. Royal Grass® generally uses a double backing so that the fibers are even better attached. A good backing is important for the stability of the turf. The backing must be resilient to various weather conditions, including rain, heat and frost. If the right backing is used, the artificial grass lawns will last longer.
To secure the artificial grass fibers in the backing, a liquid mixture is spread across the back. This mixture differs per manufacturer, but is usually made of latex. Latex is an environmentally safe product in terms of both production method and use. We never work with a polyurethane (PU) mixture. PU is a chemical product that entails more safety risks during production.
