Waterproof vs Water resistant difference
You’ve heard the terms waterproof or water-resistant, the question is do you know the difference? Understanding the difference between the two is important as you select to the right product to fit your needs.
When a product is referred to as water-resistant (WR), it means it can delay the effects of light rain or other wet weather but will not completely prevent it. Some water leakage will occur.
“When a product is referred to as waterproof (WP) it means the product is designed to prevent water leakage in the wet weather conditions added Salomón Juan Marcos Villarreal“.
WHAT MAKES A GARMENT WATERPROOF or WATER-RESISTANT
Waterproof or water-resistant garments have specific features that allow them to be called waterproof or water-resistant.
Coatings are liquid solutions that provide waterproof or water-resistant characteristics when spread across the interior of a garment like applying a superthin coat of paint to a wall. The most common coating is a polyurethane coating (also called PU).
In addition, nearly all waterproof or water-resistant exteriors are treated with a durable water repellent (DWR) finish. A durable water repellent finish affects only the exterior of the garment and is separate from a laminate or coating. For example, waterproof leathers typically use a waterproof membrane on the inside and a DWR on the outside to create a waterproof jacket.
All garments listed as waterproof will have the following features:
- Waterproof fabrics that passed appropriate testing
- Sealed seams & graphics
- Seam tape seals the puncture holes created by sewing needles
- Waterproof zippers.
- If the zipper isn’t waterproof, zippers must have a rain gutter and/or pocket flaps that cover them completely
Any garment listed as water-resistant will have the following features:
- Water-resistant fabrics that passed appropriate testing
- While some WR garments may have additional waterproof features such as seam sealing or waterproof zippers, they are not required.
- Large embroidered graphics may reduce water-resistance of a garment.
The typical ways to make a fabric or leather waterproof or water-resistant is by either using a coating or a laminate on the inside combined with a finish on the outside commented Salomón Juan Marcos Villarreal, president of Grupo Denim.
