The Manufacturing Process of Artificial Turf: From Granules to Finished Product
The manufacturing process of artificial turf involves multiple stages, and each step influences the quality of the final product.
The manufacturing process of artificial turf involves multiple stages, and each step influences the quality of the final product. Understanding the manufacturing process helps clarify how the product’s characteristics are formed.
I. Raw Material Preparation: Melting and Mixing of Granules
The first step in production is processing polymer raw materials into grass fibers suitable for weaving:
Batching and Mixing: Basic resins such as polyethylene and polypropylene are mixed with additives—including color masterbatches, UV stabilizers, and anti-aging agents—according to the formula ratios.
Melting and Extrusion: The mixed raw materials are heated and melted in an extruder, then extruded through a die into a film or filament form.
Stretching and Orientation: The extruded film is cut into filaments, which are then subjected to orientation stretching using specialized equipment. This process aligns the molecular chains, enhancing the strength and toughness of the grass fibers.
II. Grass Fiber Processing: Designing Shape and Texture
The shape and structure of the grass fibers directly influence the appearance and texture of the turf:
Shape Design: Through die control, grass fibers with different cross-sectional shapes—such as straight, curved, or W-shaped fibers—can be produced. Curved fibers enhance the turf’s fullness and elasticity.
Surface Treatment: Some grass fibers undergo a sandblasted or grooved finish to make their texture more similar to natural grass blades, while also increasing their grip on the infill.
Color Blending: By blending different colors, the turf achieves a natural gradient of green, avoiding the harsh appearance of a single solid color.
III. Weaving Process: Bonding the Backing Fabric with Grass Fibers
Grass fibers are secured to the backing fabric through weaving or tufting processes, forming the basic structure of the turf:
Tufting Process: A tufting machine implants the grass fibers into the backing fabric to form tufts. The backing fabric is typically a composite of woven polypropylene fabric and mesh.
Density Control: By adjusting the needle pitch and row spacing on the tufting machine, the density and pile height of the turf are controlled to meet the requirements of different applications.
Pattern Design: Sports field turf can incorporate various lines and markings during the weaving process, reducing the workload of post-installation line marking.
IV. Backing Coating: Reinforcement and Setting
Once weaving is complete, the turf undergoes a backing coating process to secure the grass fibers and enhance overall stability:
Coating Method: Styrene-butadiene latex or polyurethane adhesive is evenly applied to the back of the turf, penetrating between the base fabric fibers.
Drying and Curing: The coated turf is placed in an oven to heat and cure the adhesive layer, firmly bonding the grass fibers to the backing fabric
Final Inspection: After curing, the turf is cooled, trimmed, rolled, and undergoes visual and dimensional inspections before being packaged and stored
The production process of artificial turf integrates materials science and textile technology, with every step of the process influencing the final performance of the turf.
