Water repellant water proof and breathable fabric
what’s the difference between our water repellent fabric with other repellent fabric
Our water repellent and water proof fabric is a 3-layer fabric, outer layer called the “face fabric”, usually made of nylon or polyester, and a laminated membrane or coating, usually made of ePTFE (expanded Polytetrafluoroethylene, also known as Teflon®) or PU (Polyurethane). The purpose of the face fabric is to protect and look stylish; it’s not waterproof but is treated with a solution called DWR (Durable Water Repellent) so it doesn’t soak up water. But these fabric can blocks wind while deflecting moisture,
The job of keeping the water out is left to the membrane the secend ayer, which has tiny holes too small to let liquid water enter but large enough to allow water vapor to escape. Since contamination with oil, sweat and chemicals can cause PTFE membranes to lose their ability to keep out water,the membrane is protected by an ultra-thin layer of Polyurethane or other oleophobic (oil-hating) treatment.
What is Durable Water Repellent or DWR?
DWR stands for Durable Water Repellent. It is the DWR treatment that keeps the outer layer of your fabric from getting soaked by precipitation. Almost all outerwear exterior fabrics are treated with some sort of DWR. The treatment is meant to keep the fabric from becoming saturated with water which can make the fabric feel heavier, colder, and impacts its performance.
DWR causes water to bead-up and roll off the fabric and is affected by abrasion, dirt and body oils. Falls on the mountain, rubbing against your pack or the chairlift, and normal use can cause the factory DWR treatment to wear off. This is why, after some use, a garment will appear to no longer be waterproof.
