Decitex
The decitex (dtex) is a unit of measurement used to describe the density of yarn or fiber; that is, it's a way to measure how thick or thin a yarn is. It is the mass in grams of 10,000 meters of yarn.
Decitex values between 7,000 and 10,000 are considered fine threads. Values above 13,000 are considered coarse threads. Learn more about Decitex.
Thread content
This refers to the specific materials used to manufacture the turf fibers. These materials determine characteristics such as durability, UV resistance, and the overall appearance of the turf. In many cases, it is a combination of polyethylene and polypropylene.
Polyethylene (PE)
It's a type of plastic commonly used in artificial turf due to its softness and UV resistance. This makes it ideal for high-traffic areas and those exposed to sunlight.
Polypropylene (PP)
Another type of plastic known for its durability and moisture resistance is crimped polypropylene. It adds extra texture to the turf, giving it a more natural look.
Thread height
It is the length of the grass strand from the base to the tip. This measurement is important because it influences the appearance, texture, and use of the turf.
grass is defined as grass Short-pile artificial with a pile height between 10 and 30 mm. Grass with a pile height between 35 and 60 mm is considered long-pile.
Greyhound
The space between the rows of fibers, measured in inches, is a key measurement because it determines the density of the turf and, therefore, its appearance and functionality.
For example: 3/8 inch means there are 3/8 inch (approximately 9.53 mm) between each row of yarns. A smaller gauge means the yarns are closer together, giving the lawn a denser, more luxurious appearance. Conversely, a larger gauge, such as 5/8 inch, means the rows of yarn are farther apart, resulting in a less dense lawn.

Stitches/ml
The number of stitches (or rows of threads) in one meter of length indicates how many times the thread is inserted into one meter of the base of the turf.
Low density is considered to be below 150 stitches/ml; medium density between 150 and 190 stitches/ml and high density if it exceeds 190 stitches/ml.
Stitches/m2
Total number of stitches or rows of threads in an area of one square meter. This measurement provides an idea of the density of the turf across its entire surface.
For example, if a lawn has 17,850 stitches per square meter, it means that in each square meter of the lawn surface there are 17,850 stitches; the higher the number of stitches, the greater the density.
Low density is considered to be below 16,000 stitches/m2; medium density between 16,000 and 20,000 stitches/m2 and high density if it exceeds 20,000 stitches/m2.
Thread weight
Amount of material (yarn) used in one square meter of turf. It is measured in grams per square meter (g/m²).
For example, if the table indicates that the yarn weight is 1,660 g/m² ± 5%, it means that each square meter of artificial turf contains approximately 1,660 grams of yarn. This value may vary slightly due to manufacturing tolerances (± 5%).
The weight of the yarn is important because it affects the density, softness, and durability of artificial grass. A higher yarn weight generally indicates a denser and more durable turf.
- 800g/m2 is considered low weight.
- Medium weight with a good balance between density, softness and durability if the yarn weight is between 800 and 1200 g/m2.
- High weight with high density and quality if the weight of the yarn is greater than 1200 g/m2.
Shape
This refers to the shape of the turf fibers. The shapes of the fibers can vary and are designed to mimic the look and feel of natural grass, as well as improve the performance and durability of the artificial turf.
Some common forms are:
C-shape
Filaments with this shape have a curved structure that allows them to stand upright and offer a more realistic appearance. They also help reflect less light, reducing artificial glare.
W-shape
Filaments with this shape have a "W" structure that offers a more natural appearance and helps keep the filaments upright. It also improves resistance to wear and tear.
Flat shape (Straight shape)
Filaments with this shape are wider and flatter, which can give the lawn a softer, more uniform appearance . However, they may tend to flatten more easily over time.
S-shape
The curvature of this filament shape means less light reflects off the artificial grass, preventing it from heating up as much in high temperatures. The appearance is more natural, as the synthetic turf's glare is less noticeable.
Spine shape
This filament features a central rib that facilitates air circulation, thus reducing the accumulation of debris. It offers a balance between softness and rebound with each step.
Drainage holes
Small holes found at the base of the lawn. Their purpose is to allow rainwater or other liquids to pass through the lawn and drain into the underlying soil, preventing water from accumulating on the surface.
Holes/m2
Numberof holes in an area of one square meter. For example: 80-100 drainage holes provide good capacity to keep the lawn dry and functional.
Total Weight
Combined weight of all materials used in the manufacture of the turf per square meter. This includes the yarn, primary backing, secondary backing, and any additional coatings or materials.
Heavier grass is usually more robust and durable.
- Low quality with a total weight of less than 1,500 g/m2.
- Standard quality with a total weight between 1500 and 2500 g/m2.
- High quality or premium range with a total weight greater than 2,500 g/m2.
Primary backing
This refers to the layer of material onto which the turf fibers are sewn or embedded. This layer provides stability and support to the turf fibers, ensuring they stay in place and contributing to the durability of the final product.
Secondary backing
Itis an additional layer of material applied over the primary backing. Its main function is to provide greater stability and strength to the turf, ensuring that the grass fibers remain in place and improving the overall durability of the product.
Coating Backing
It is the coating layer applied over the primary and secondary backing. This additional layer provides greater durability and stability to the artificial turf, ensuring that the grass fibers remain firmly attached and increasing the product's resistance.
Permeability
The ability of the grass to allow water to pass through it and drain into the underlying soil. This characteristic is crucial to prevent water from accumulating on the surface of the grass, which could cause puddles and impair its functionality.
- Low drainage if it is less than 30L/min/m2
- Adequate drainage if it is between 30 and 60 L/min/m2.
- High drainage if it is greater than 60 L/min/m2.
Total height
The distance from the base of the backing to the tip of the longest turf fibers. This measurement includes both the height of the fibers and any backing layer or infill that forms part of the turf structure.
The overall height is important because it influences the appearance and use of the artificial turf:
- Greater height: It usually looks more like natural grass and can be more comfortable for walking or playing.
- Lower height: It can be more durable and suitable for high-traffic areas.
Sand fill
Infilling with silica sand is essential for maintaining the stability and functionality of the turf. It is a fine, uniform grain sand; adding 5 kg/m² is recommended for even coverage.
Among the benefits of adding silica sand we can highlight:
- Stability. Helps keep the grass filaments upright, providing a uniform surface and preventing them from being flattened.
- Additional weight. Adds weight to the turf, which helps to keep it in place and prevent shifting.
- Improved drainage. Facilitates the flow of water through the lawn, improving permeability and preventing puddles.
- Natural feel. Provides a softer, more natural surface, similar to real grass, when walking or playing on it.
