As a specialist, do you know this about artificial turf?

Artificial turf is favored by many consumers due to its all-weather, evergreen, environmental protection, durability, economy, maintenance-free and easy construction. Artificial turf is also used in a wider range of fields, such as football, hockey, tennis, golf, rugby, basketball and other sports fields, as well as multi-purpose grass, landscape grass, airport grass, etc. There are many artificial turf manufacturers on the market, and the variety of products is dazzling. From the appearance alone, outsiders may not be able to control the quality of artificial turf. The following Wanhe Grass will take you to make up for the basic knowledge of artificial turf.

Read carefully and pay attention to Wanhe Grass and you will get something.

Raw materials

The raw materials of artificial turf are mostly polyethylene (PE), polypropylene (PP) and nylon (PA).

1.Polyethylene (PE): higher cost performance, softer hand, appearance and sports performance closer to natural grass, widely accepted by users, is currently the most widely used artificial grass fiber raw material on the market.

2.Polypropylene (PP): The grass fiber is hard, and simple fibrillation is generally suitable for tennis courts, playgrounds, runways or decorations, and its wear resistance is slightly worse than polyethylene.

3.Nylon (Nylon): It is the earliest artificial grass fiber raw material and the best artificial turf raw material, belonging to the first generation of artificial grass fiber. Nylon artificial turf is widely used in developed countries such as the United States, but the price is higher in my country, and most customers cannot accept it.

The bottom

1.Vulcanized wool PP woven bottom: durable, good anti-corrosion performance, good adhesion to glue and grass thread, easy to be firm, the price is 3 times that of PP knitting.

2.PP braided bottom: general performance, weak binding force. Glass thousand-dimensional bottom (grid bottom): The use of glass fiber and other materials is a good help to increase the strength of the bottom and the binding force of grass fibers.

3.Pu bottom: strong anti-aging performance, durable; strong adhesion to the grass thread, environmental protection and odorless, but the cost is higher, especially imported PU glue is more expensive.

4.Woven bottom: The braided bottom does not use a backing, and the glue is directly attached to the fiber root. This bottom can simplify the production process, save raw materials, and more importantly, it can meet the prohibited sports items of ordinary artificial grass, such as : Javelin, etc., but the woven bottom has high requirements for equipment and craftsmanship, and this type of product has not yet appeared in China.

Glue

1.Styrene-butadiene latex is the most common material in the artificial turf market in my country, with good functions, low cost, and water-soluble properties.

2.Polyurethane (PU) glue is a universal material in the world. Its strength and binding force are several times that of styrene-butadiene latex. It is durable, beautiful in color, non-corrosive, moldy and environmentally friendly, but the price is more expensive. It has a market share in China Lower.

Product structure identification

1.Appearance. Bright color, no obvious color difference; flat grass seedlings, uniform tufting, overall flatness, uniform stitch length, no skipped stitches, good consistency; moderate glue at the bottom and penetrates into the bottom lining, no glue leakage or damage.

2.Specifications The length of the grass yarn. In principle, the longer the football field is, the better (outside the leisure field). At present, the longest grass yarn is 60mm, which is mainly used for professional football fields. The most common grass yarn for football fields is about 30-50mm.

3.The density of grass silk. From two perspectives

3.1.Looking at the number of grass needles from the back of the lawn, the more needles per meter of grass, the better.

3.2.See the row spacing from the back of the lawn, that is, the row spacing of grass filaments. The denser the row spacing, the better.

4.The grass size and fiber diameter of the fiber yarn. Common sports grass yarns are 5700, 7600, 8800 and 10000, which means that the higher the size of the grass, the better the quality. The more the number of grass filaments per cluster, the finer the grass and the better the quality. The diameter of the fiber is calculated in μm, generally between 50-150 μm. The larger the fiber diameter, the better. The larger diameter gives the impression that the grass filaments are thick and wear-resistant. The small fiber diameter is like a thin plastic sheet, which is not wear-resistant. The index of fiber yarn is generally difficult to measure, so FIFA generally uses the index of fiber weight.

5.Fiber quality. The larger the mass of the same unit length, the better. The pound weight of the grass fiber is in the unit of fineness, and it is defined as 1Dtex per 10,000 meters of fiber with a mass of 1 gram. The heavier the grass fiber weight is, the thicker the grass fiber is. The greater the grass fiber weight, the stronger the abrasion resistance. The larger the grass fiber weight, the longer the service life. However, the larger the grass seedling fiber weight, the higher the cost. Choose the appropriate grass seedling weight according to the age group and frequency of use of the athletes. For large sports venues, it is recommended to use grass woven lawns with a weight of more than 11000Dtex.

6.Other aspects. Artificial turf is used for use or to beautify the living environment, so the most important foot feel and color quality are the first factors to consider. If it is a sports turf, consider the feeling of athletes running on it, the ball feel-the ball is in Whether the above running track meets the requirements of the game.

Brand selection

Brand is a kind of evaluation and cognition formed by users on a company and its products' excellent product quality, good product image, perfect after-sales service, and excellent corporate culture. It is a long-term investment of huge manpower and material resources by the company. A kind of trust established with users. Therefore, when choosing an artificial turf brand, you should first understand the history of the brand's development, whether it has stable product quality assurance, has the testing and certification of authoritative institutions at home and abroad, and must have a complete and professional service system.
