How Artificial Turf is manufactured
Artificial turf is a tough material built to withstand the stresses of everyday use. These surfaces made from long lasting polymers that are meant to retain their colour and texture despite prolonged exposure to the elements. Artificial Grass typically consists of three major components: The grass filament, infill media, and backing material.
The upper part of the artificial turf is made using tufting methodssimilar to those used to make carpets. First. All the proprietary ingredients are combined in a hopper. Chemicals and dyes are added to the mix to give the turf to protect the turf from ultraviolet tight and to give it its customary green colour. After the components have been thoroughly mixed, they are transferred into a large steel mixer. The lot is mixed at a constant rate until it acquires a thick consistency. The thickened liquid is sent to an extruding machine and comes out in the form of a long thin strand. The strands are fed into a carding machine and combined into a loose rope. The ropes are then woven into yarn which is wound onto large spools. The yarn is heated to set its twisted shape and tufted. The proper installation and maintenance are important to ensure that artificial turf performs as expected. The base of the installation, which may be made of concrete or compacted soil must be levelled and smoothened by a steam roller, otherwise the surface will appear uneven after the grass has been laid. For outdoor installations, it is imperative that there is a proper drainage system before the carpet is laid. Since the underlying surface has been compacted and levelled, it may not absorb much water.
Artificial turf can be either filled or unfilled. Filled systems are created in such a way that after installation, material such as granulated rubber or sand can be spread over the surface and raked down in-between the fibres. This is provides support for the blades of fibre and also creates a softer surface. The result is a surface that feels more natural. However, filled surfaces also come with a number of shortcomings. Filling materials like cork may break down or get contaminated. This would cause compaction and as a result, the tufts of grass would lose support. Maintenance may necessitate removal and replacement of the entire filler material. Artificial turf is a product that must often endure constant use and exposure to the elements. This being the case, each carpet is subjected to stringent testing before it can be sold. In accordance with guidelines set by the American society for testing and materials, the backing fabric must be tested for strength. The strength of individual tufts of grass is also measured. Other tests include abrasion, shock absorbency and durability.
