Popular Science of Artificial Turf: A Comprehensive Analysis from Principles to Applications

In modern society, as a powerful alternative to natural turf, artificial turf is widely used in various places, ranging from professional sports venues to leisure landscape areas. But what exactly is artificial turf? What characteristics and applications does it have? This article will provide a detailed popular science introduction to artificial turf.

I. Definition and Composition of Artificial Turf

Artificial turf is a type of ground paving material made of synthetic materials, which simulates the appearance and function of natural turf. It mainly consists of three parts: turf fibers, base fabric, and back glue.

1. Turf Fibers: Turf fibers are the core part of artificial turf, determining its appearance and touch. The materials used to make turf fibers are mostly synthetic fibers such as polyethylene (PE), polypropylene (PP), and nylon (PA). Among them, polyethylene, with its excellent wear resistance and elasticity, is often used in sports field turf; polypropylene has the characteristic of crimped fibers, with a natural appearance, and is mostly used in leisure areas; nylon has both ultraviolet (UV) resistance and anti-aging properties, so it can be used in both sports-type and leisure-type venues. To make the color of turf fibers closer to that of natural turf and ensure long-lasting durability, environmentally friendly green color masterbatch is also added. Turf fibers are made into semi-finished products through processes such as melting extrusion, spinning, and water bath cooling, and then undergo twisting and weaving to form finished turf fibers with a certain strength and shape.

2. Base Fabric: The base fabric is the foundational layer that supports the turf fibers. It is generally made of PP mesh fabric or woven base fabric, and its main function is to enhance the overall strength and stability of the turf, ensuring that the turf fibers can be firmly attached.

3. Back Glue: The back glue is coated on the back of the base fabric to fix the turf fibers and prevent them from falling off, playing a crucial role in extending the service life of artificial turf. Common back glue materials include styrene-butadiene rubber (SBR) latex and polyurethane (PU). SBR latex back glue has a lower cost and is widely used, but its water resistance and durability are relatively weak; polyurethane back glue has superior performance, with excellent water resistance, wear resistance, and flexibility, and is often used in high-quality artificial turf for sports venues.

II. Types of Artificial Turf

According to different usage scenarios and functional requirements, artificial turf is mainly divided into sports-type artificial turf and landscape-type artificial turf.

1. Sports-Type Artificial Turf

• Artificial Turf for Football Fields: This is one of the most common types of sports-type artificial turf. Professional artificial turf for football fields requires excellent wear resistance, lodging resistance, and good ball rebound performance. The turf fibers are generally made of PE material, with a height usually ranging from 50mm to 60mm, a density of about 10,500 to 13,000 stitches per square meter, and a row spacing of 3/8 inch. These specifications ensure that the rolling speed and direction of the football on the turf meet the competition requirements, while reducing the risk of injury to athletes.

• Artificial Turf for Tennis Courts: Artificial turf for tennis courts has high requirements for surface flatness and friction, and is divided into two types: hard-surface and soft-pad. The turf fibers of hard-surface tennis court artificial turf are relatively hard, with a height of 10mm to 20mm, suitable for players who pursue speed and strength; the soft-pad tennis court artificial turf has an additional elastic underlay at the bottom, and its turf fibers are slightly longer and softer, with a height of approximately 25mm to 35mm. This design can provide better cushioning, reduce the pressure on athletes' joints, and control the rebound height of the tennis ball.

• Artificial Turf for Golf Courses: Artificial turf for golf courses needs to accurately simulate the hitting performance of natural turf and the rolling effect of golf balls. The turf fibers in the putting green area are the finest and densest, with a height usually ranging from 5mm to 8mm, ensuring the stable rolling of golf balls; the turf fibers in the tee box and fairway areas are relatively thicker and taller, with a height of about 20mm to 30mm, providing appropriate support for players' shots.

1. Landscape-Type Artificial Turf

• Leisure Landscape Artificial Turf: It is often used in leisure places such as parks, residential communities, and courtyards, with an emphasis on aesthetics and comfort. The turf fibers come in a variety of colors, simulating the layering of natural turf. The height is generally 20mm to 40mm, with a moderate density and soft texture, suitable for leisure activities such as picnics and playing.

• Roof Greening Artificial Turf: Due to the special environment of the roof, artificial turf for roof greening has high requirements for weight, drainage, and weather resistance. Lightweight materials are usually used, and the height of the turf fibers is relatively low, ranging from 15mm to 25mm, to reduce the load on the roof. At the same time, it has good drainage performance, which can quickly drain rainwater and avoid water accumulation on the roof. In addition, it has undergone special treatment to resist harsh weather conditions such as ultraviolet rays, high temperatures, and low temperatures, ensuring a long service life.

III. Advantages of Artificial Turf

1. Stable Year-Round Use: Artificial turf is not affected by seasons and climates, and can maintain stable performance throughout the year. Whether in cold winters or hot summers, it can be used normally, meeting the needs of all-weather and high-intensity sports or leisure activities.

2. Easy Maintenance: Compared with natural turf, artificial turf does not require complex maintenance work such as watering, fertilizing, pruning, or pest control, which greatly reduces maintenance costs and labor input. According to statistics, the maintenance cost of artificial turf is less than 5% of that of natural turf.

3. Excellent Site Uniformity: Artificial turf has outstanding flatness and uniformity, which can fully avoid poor site conditions caused by factors such as climate and maintenance. It provides a stable sports surface for athletes, reducing the risk of injury caused by uneven ground, and at the same time ensuring the normal conduct of sports events. For example, the rolling trajectory of the football on the turf is more stable.

4. High Safety Performance: The new generation of artificial turf fibers has been improved in terms of surface coating and polymer raw materials, which effectively reduces the occurrence of sports injuries such as skin scratches and foot sprains, providing better protection for athletes.

5. Environmental Protection and Sustainability: Some of the raw materials of artificial turf are recyclable and reusable. Moreover, it does not require a large amount of water for irrigation, reducing environmental pollution and resource waste, which is in line with the concept of environmental protection in modern society.

IV. Application Scenarios of Artificial Turf

1. Sports Venues: Artificial turf is widely used in various sports venues such as football fields, tennis courts, golf courses, hockey fields, baseball fields, and basketball courts. It provides a good sports surface for athletes, enhances the sports experience, and at the same time extends the service life of the venue and reduces maintenance costs.

2. Leisure Landscapes: In leisure landscape areas such as parks, residential communities, courtyards, roof greening, hotels, and kindergartens, artificial turf creates an aesthetic environment with evergreen scenery throughout the year, providing a comfortable leisure space for people. The special artificial turf for kindergartens also has advantages such as special design, environmental protection and safety, beautiful appearance, and strong adaptability, fully covering and replacing traditional paving materials such as plastic and PVC.

3. Commercial Places: Some commercial places, such as shopping malls and exhibition halls, also use artificial turf for decoration to create a natural and comfortable shopping or exhibition environment and attract customers.

V. Maintenance of Artificial Turf

Although the maintenance of artificial turf is relatively simple, proper care is still needed to extend its service life.

1. Daily Cleaning: After events or regularly, use a vacuum cleaner to clean up debris such as paper and fruit shells; comb the turf fibers with a special brush every two weeks to remove dirt and leaves; level the quartz sand or rubber granules (if filled) with a special rake every month or after frequent competitions.

2. Stain Removal: Adopt different cleaning methods for different stains. For example, for "water-based" stains such as fruit juice and milk, first scrub with soapy water, then rinse with clean water; for stains such as shoe polish and ballpoint pen ink, wipe with a sponge dipped in perchloroethylene.

3. Inspection and Repair: Regularly and carefully check whether the seams are loose, and whether there is damage, tearing, or burning at the bottom of the turf. If problems are found, contact the paving company for repair in a timely manner; heavy rain and cleaning may cause minor loss of infill, so it is necessary to replenish quartz sand, rubber granules, etc. in time.

4. Usage Precautions:

• It is forbidden to wear spiked shoes (including high-heeled shoes) with a length of 5mm or more for strenuous exercise on the turf;

• It is forbidden to drive motor vehicles on the turf;

• Avoid long-term placement of heavy objects;

• It is forbidden to conduct high-impact sports such as shot put and javelin on the turf;

• Various types of oil pollution on the turf are strictly prohibited;

• In snowy weather, the surface floating snow must be cleaned before use;

• Littering chewing gum and debris on the turf is strictly prohibited;

• Open flames are strictly prohibited;

• The use of corrosive solvents is prohibited.

With its unique advantages and diversified applications, artificial turf is gradually becoming an indispensable ground paving material in modern society. By understanding the relevant knowledge of artificial turf, we can better select and use it, creating a better environment for life and sports.
