How to test the water resistance of polyester fabric before purchasing outdoor cushions?

When shopping for outdoor cushions, ensuring the polyester fabric is water-resistant is crucial for longevity and performance. Here’s how to test it before purchasing:

1. Water Droplet Test: Sprinkle a few drops of water on the fabric. If the water beads up and rolls off, the fabric is water-resistant. If it soaks in quickly, it lacks adequate protection.

2. Check the Label: Look for terms like "water-repellent," "waterproof," or a high hydrostatic head rating (measured in mm), indicating better resistance.

3. Rub Test: Lightly rub the fabric with a damp cloth. If water penetrates or stains appear, the coating may be insufficient.

4. Ask for Specifications: Request technical details from the seller, such as the type of coating (e.g., PU or PVC) and its durability.

5. Real-World Simulation: If possible, expose a sample to light rain or mist and observe how it handles moisture.

Choosing polyester fabric with proven water resistance ensures your outdoor cushions stay dry and durable in all weather conditions.
