DTex expresses the length/mass ratio and is measured as the weight of the fibre per 10,000 metre length. A Dtex of, for example, 10,000 means that a fibre with a length of 10,000 metres weighs 1 kilo. The fibre thickness is also important: the thicker a fibre is, the longer it will remain upright. With Premier Grass artificial grass, the “C” shape strengthens the effect of fibre thickness in helping to keep the blades of grass upright.
The total square meter weight of the fibres 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 fibre weight per square metre and the fibre length for artificial grass types with a root zone (also called artificial moss) is a minimum weight of 45 to 60 grams per millimetre fibre length.
