What is waterproof fabric?
Waterproof fabric is usually a textile which is compounded with polymer waterproof, breathable materials.
How is it manufactured?
There are 4 main types of waterproof, breathable fabrics which are manufactured slightly differently:
- Tightly Woven Fabrics – great for the outdoors; an Egyptian cotton, woven very tightly. When it gets wet the cotton swells and makes the weave even tighter.
- Fabrics with Membranes – PTFE and PU are polymers most frequently used to make microporous coatings for fabrics.
- Fabrics with a Continuous Hydrophilic Coating – made from a solid, water-repellent coating which has no pores but it is impermeable to air. Normally a mix of PU and PEO.
- Biocomponent Microporous and Hydrophilic Laminates – modern Gore-Tex. Impermeable to air with excellent breathability. Very durable.
Water-repellent fabrics are usually woven materials, that have been manufactured to partially repel water.
Purposes of waterproof fabric
- Raincoats
- Jackets
- Anoraks
- Cagoules
- Outdoor Wear
- Ski Wear
- Sportswear
- Footwear
- Bags
- Rucksacks
- Luggage
- Aprons
- Protective Clothing
- Umbrellas
- Hats
- Tents
- Awnings
Properties
Waterproof fabrics have many desirable qualities which make them appealing and necessary for a wide range of uses. They completely prevent the penetration and absorption of water in contrast to water-repellent materials.
They also have excellent heat resistant properties and hold up well in cold temperatures.
Different kinds of waterproof textiles suit different projects. Here are some frequently used ones:
- Oilcloth – 100% vinyl, completely waterproof, shiny, durable, doesn’t fray
- Ripstop – tough, nylon threaded material, resistant, good waterproof outdoor fabric
- Waterproof Cotton Fabric – waterproof, breathable, moisture-wicking, pliable, drapes well
- Waterproof Canvas Fabric – used for outdoors, strong, breathable, mildew and rot resistant
- Sandwich PUL – composed of 3 layers, laminate layer sandwiched between knitted layers
- Polyurethane Laminate – waterproof, breathable, 2-sided, slight stretch, laminate coating
Advantages of waterproof fabric
From making raincoats and tents to umbrellas, tablecloths and sportswear, waterproof fabric has so many advantages. These materials won’t allow water seepage and are generally easy to clean and care for.Thanks to the advances in polymer chemistry which is how waterproof fabrics have become so much more advanced, modern waterproof textiles can now be breathable. They let perspiration out while preventing water penetration.
