Due to the problems of cost, cost and maintenance, most football fields choose to lay artificial grass today. Today, I will give you a popular science of the production process of this artificial grass.
Most artificial turf football fields are generally made of two kinds of materials: polypropylene (Polypropylene, referred to as PP) and polyethylene (Polyethylene, referred to as PE).
The artificial turf made of PP material is firm and has a small buffering force, and is generally suitable for sports with low impact force such as tennis. The artificial turf made of PE material has soft texture, good cushioning performance, and little damage to athletes. It is suitable for sports with high impact force such as football and rugby. It is also possible to mix the two materials to make artificial turf, so that the advantages of the two can be combined to meet the needs of special competitions. For some high-intensity sports competitions, in order to improve the quality of the game and minimize the injury of athletes.
When choosing artificial turf, it is generally necessary to choose a fiber material with a relatively high height, usually 25 to 50mm, and choose a PE artificial turf or a PE/PP mixed material artificial turf. In the construction of artificial turf sports fields, when choosing the height of artificial turf, it is generally necessary to consider the overall budget of the stadium. The artificial turf with a relatively high height has relatively high construction and maintenance costs.
Plastics of these sizes are generally referred to as "masterbatches", and the artificial grass you can see and kick is made from countless such masterbatches.
These colorful candy-like particles are masterbatches. Generally speaking, the initial masterbatches are white.
These are all wire drawing machines in the picture above. As the name suggests, they are responsible for drawing the masterbatch into... into... wire. Of course, there are processes such as dyeing before this.
What is the masterbatch that is drawn into silk? Just like the picture above! Have you ever remembered how silkworm cocoons turned into silk rolls, and the next step of silk rolls is spinning, yes, the next step for these rolled grass silks is weaving, yes, weaving them into lawns.
That's right, it's these loom-like guys who put on the sand heads one by one, and then weave them. Then the equipment on the last picture is shrimp? The opportunity to gain insight has come. This is called a dryer. After the lawn is woven, the backside should be coated with adhesive. After the adhesive is applied, it needs to be dried.
Because artificial turf is generally used outdoors, it is easy to remove accumulated water in rainy days. This is not man-made damage.
These are the finished products. The lawn is almost rolled like this. Do you remember the rolls of carpet grass laid by the green workers in the summer? Yes, the principle of laying is the same, but the standard and process are more complicated.
