Water Proof and Water Repellent Fabric Finishes
Fabrics to be used as raincoats, umbrellas, and tarpaulins have to be treated with chemicals to give them a property which makes them water resistant. The finish is called waterproofing and it is a durable finish. Water repellant finish is different from the waterproof finish. It means water, if showered on the fabric briefly, cannot make the fabric wet.
