When evaluating artificial turf, you must focus on Pile Height, Stitch Rate, and Dtex (Fiber Density). For professional soccer fields, a pile height of 50mm-60mm is standard, while multi-purpose fields may use 30mm-40mm. Ensure the fiber material is PE (Polyethylene) for softness and durability, and verify the UV resistance rating to prevent fading and degradation under intense sunlight. Additionally, the backing material should be reinforced with PP+Net+Latex to ensure high tuft withdrawal force.
