How do manufacturers test the water resistance of seams in fabric-based landscape chairs?
Manufacturers employ rigorous testing methods to evaluate the water resistance of seams in fabric-based landscape chairs, ensuring they withstand outdoor conditions. One common method is the spray test, where chairs are subjected to controlled water spray to simulate rain. The fabric and seams are inspected for water penetration after a set duration. Another technique involves submersion testing, where seams are immersed in water to check for leaks under pressure. High-quality chairs often undergo hydrostatic pressure tests, measuring how much water pressure the seams can resist before failing. Advanced manufacturers may also use dye penetration tests, where colored water is applied to seams to visually identify weak points. These tests help ensure the chairs remain dry and comfortable even in wet environments.
