How to assess the quality of warp-knitted netting? What are the key indicators?

Core assessment criteria include:

① Wire diameter tolerance: High-quality netting exhibits wire diameter uniformity deviation not exceeding 5%, verifiable via calipers through sampling;

② Mesh precision: Mesh aperture edge deviation ≤2mm, with no noticeable distortion or skew;

③ Tensile strength: Competitive-grade nets must exhibit a transverse tensile strength of no less than 15 kN/m, while protective nets require no less than 20 kN/m;

④ Weather resistance: Outdoor nets must pass UV ageing tests, ensuring no significant brittleness after three years of prolonged exposure to sunlight;

⑤ Visual quality: Free from defects such as missed stitches, loose threads, or protruding knots, with flat, secure selvedges showing no loose threads.
