Functional distinction between waterproof fabrics and water-repellent fabrics

1. Waterproof products are more durable and have more stable physical and chemical properties than water-repellent products.
2. Waterproof products usually do not lose effectiveness due to washing and long-term use.
3. Waterproof products have higher water pressure resistance indicators than water-repellent products, usually at least 3000mmH₂O.
4. In the specific application of clothing, the main function of the water-repellent treatment is to reduce the adsorption of water by the fabric so that the water can be "pushed away" on the surface of the fabric; the waterproof treatment is a completely impermeable barrier, regardless of whether the fabric absorbs water or not. , it keeps water out.
