What is Waterproof Upholstery Fabric?
When you’re looking for waterproof fabric for outdoor seating, it can be a little confusing to understand what manufacturers really mean when they call something waterproof and how to choose outdoor fabric that delivers premium performance -- come rain or shine. Here’s everything you need to know.
Waterproof vs. Water-Resistant Upholstery Fabric
People and companies may use the word waterproof when they actually mean water-resistant or water-repellent.
What is Waterproof Fabric?
Truly waterproof materials may be made of rubber or plastic and do not allow any water to penetrate at all. That sounds great until you realize that a material that is waterproof is also air proof.
This is a problem for a couple reasons:
Without some degree of breathability, waterproof outdoor fabric can encourage the growth of mold or mildew inside a cushion: if a small amount of water sneaks in through a seam, it will stay there. Instead of drying out quickly, the dampness in the cushion will quickly become a breeding ground for microorganisms.
- Uncomfortable Seating
Truly waterproof upholstery fabric that doesn’t breathe can also make for an uncomfortable seat on a hot day, creating a sweaty, sticky surface wherever it comes into contact with your skin.
When looking for outdoor fabrics for furniture applications, you should instead look for a fabric that is water resistant or water repellent and that also allows for good airflow.
What is Water-Resistant Fabric?
“Water-resistant” is a more transparent term for fabric that won’t be damaged by contact with water. Water-repellent means that the fabric is not absorbent: if you get it wet you’ll mostly see the moisture beading on the top of the fabric instead of soaking in. When water-resistant fabric does get wet, the water that remains on the surface of the fabric will dry out quickly.
What Makes an Outdoor Fabric Water-Resistant?
When a fabric is labeled as “water-resistant”, the term usually refers to one or more of a few different water-resistant qualities:
This is the most relevant factor. Man-made fibers can vary in their absorbency, but some are naturally hydrophobic, which means that they repel water on a molecular level. Fabrics with olefin or vinyl content are good examples of this.
Many so-called waterproof materials may not naturally repel water, but have been treated with special “waterproofing” solutions or agents that are applied or sprayed onto the surface of the fabric after it has been woven. The solution (which could be made from rubber, wax, polyvinyl chloride or some other mixture) forms a coating that acts as a barrier between moisture and the fabric.
High-denier or high-density fabrics can be more water repellent than more loosely woven fabrics. The more tightly a material is woven and the higher the thread count, the more difficult it is for moisture to penetrate the fabric.
Types of Water-Resistant Designed Fabrics
While almost any fabric can be treated to become more water resistant, if you are looking for water-resistant material for a DIY project you’ll have better luck with naturally water repellent materials such as:
Olefin yarns are spun from polypropylene fiber, which is water repellent. Not only does it not absorb moisture, it actively pushes it away. Because wetness doesn’t penetrate the fiber, a spilled glass of wine at a backyard cookout can be easily wiped up and is less likely to cause stains. It will also air dry in a snap after rain or a wash.
Polyester is naturally water-resistant, but once you coat polyester yarns with vinyl or PVC and weave them together, the water resistance is off the charts. The coating on each strand of yarn in the fabric protects the polyester, and keeps water from penetrating into the fiber. Because this brilliantly water-resistant outdoor fabric is a mesh, air flow is excellent as well.
Why Water-Resistant Fabrics Matter Depending on Where You Live
The more rain your location gets, the more important it is to choose a water-resistant fabric. Under these conditions, you need water-resistant fabric that will repel water and dry quickly between storms so that it’s ready to use when the sun does come back out. Constantly damp outdoor fabric isn’t just uncomfortable; it’s also at risk for developing problems with mold, mildew, and rot.
