How does the artificial turf industry work?
How to make artificial grass, and we will start with the same industrial components, which are
The chemicals that artificial grass is made of, as we said
Before that, the artificial grass originated from polymers of “polycarbonate” chemicals
Propylene or “polyethylene” and these materials are chemically inert in nature
I mean, it does not interact with other materials
And when the manufacturing process begins, they convert the solid state into polymers
For the liquid case, and of course, the colors of the artificial grass are added
If you want to see you, it will be red, blue or yellow, for example, and if you want green grass
Green is added.
After the polymers turn into a liquid, the liquid is placed in molds
Press and turn into threads and threads are rolled into bobbins and are ready to sew.
There are bristles for artificial grass, which are single, double, and others, and this, of course, depends on each of the pressing moulds.
The stage of carpet production or the layer on which artificial grass will be sewn will come, and it will be two layers of plastic, and its durability bike will be stronger than nylon, and it will be wrapped with fabric and plastic threads in order to be able to withstand the life span.
This is how we prepare the filaments for the synthetic grass, as well as the rug that will be sewn on.
And we enter the sewing stage, and this is done, of course, through special sewing machines. The sewing needle of the machine is about 15 cm. It is considered one of the largest sewing machines in the world of carpets, and it includes more than 500 spools of thread at one time.
Of course, after sewing, there will be a process of heating and welding, and this is in the presence of a layer of nylon, and this will be a protective layer so that there is no separation between the hairs and the fabric.
That’s why we have artificial turf. How to make sure that it is suitable for sports stadiums?
This will be the last stage, which is the quality stage, in which a sample of the synthetic turf is cut and placed under a test machine for 40 hours. If the sample is positive, this indicates that the synthetic turf is able to withstand playing under standard conditions for a period of 5 years.
And of course, after confirming the quality, the rolls are wrapped and ready for installation in sports stadiums.
