The Quality of Artificial Grass

How can you tell the difference in the qualities of all of the different types of quality artificial grass?

The quality of Artificial Grass is measured in dtex, pile height, gauge, stitch rate and the backing but just what do all of these things mean?

What does Pile Height mean?

You will find that most suppliers will state the pile height of their fake grass. Strictly speaking Pile Height should simply be how long is each upright blade of grass when measured. It is not uncommon for some suppliers to state pile heights including the height of the backing but this is not the correct way to state Pile Heights. All pile heights stated by us at Tuda Grass Direct are the heights of the blades of grass.

What does Dtex Mean?

Dtex is a manufacturing term – an abbreviation of decitex. In simple terms what this means is that if a single blade of grass was 10000m long how much would it weigh in grams.

This is important as it affects the durability of the grass. You will find that most suppliers only state the Pile Height of their grass. If you imagine that the grass blades were 30mm Pile Height but with a texture like that of paper then the grass would have a low dtex and never be suitable for our harsh UK climate and the grass wouldn’t even last 12 months. However if the grass had a texture much like string or twine then it would have a much higher dtex and stand up well to our windy and rainy conditions.

This is why dtex is important (although rarely stated by grass suppliers). The range of dtex on artificial grass tends to be between 6600 & 16800. In simple terms the higher the dtex, the more durable, and long lasting the grass will be.

What do Gauge & Stitch rate mean?

When Artificial Grass is stitched to the backing it is done in straight lines. The distance between these lines is known as the gauge. If the distance between these lines was large then the grass would not look good. The stitch rate means how many stitches there are in a square metre of grass. The combination of Gauge & Stitch Rate is what gives us the density of the grass and in simple terms the higher the density of the grass the better the quality. Premium quality artificial grass tends to have a density of around 16750 stitches per metre. Cheap artificial grass tends to have densities around 6000 stitches per metre with the exception of green grocer type grass which has considerably lower density.

What constitutes quality backing?

Backing consists of woven fabric, usually made of polypropylene. This material can be reinforced with weft threads or by adding extra layers. A good backing is important for the stability of the artificial turf. The backing must be resilient to the variety of weather conditions that we experience in the UK, including rain, wind, sun and frost. If the right backing is used, the artificial grass lawns will last longer.

During the manufacturing process to secure the artificial grass fibres in the backing, a liquid mixture is spread across the back. This mixture is usually made of latex. A good thick latex is essential to ensure the blades of grass remain fixed in place for a long period of time. The backing on all of our grasses is high quality.

Quality Artificial Grass

The above should explain why factors other than just Pile Height should be taken into account when deciding which of our quality artificial grasses to use. Pile Height, Gauge, Stitch Rate, Density, Dtex & the backing should all be considered to ensure you get the best possible grass for your installation.
