Ep163 - What Makes a Fabric Waterproof?

Water meets its match: fabric technologies demystified! When it rains, it pours - but it doesn't have to bore! In this episode, Ben is presented with another opportunity to geek out, and this time our gear gurus unfold the complex world of waterproof fabrics. From the fundamental differences between waterproof, water-resistant, and water-repellent, to hydrostatic head ratings and coatings - Ben and Lauren decode every last drop. The conversation flows through PE versus PU treatments, siliconised fabrics, laminated materials, and the beading beauty of DWR coatings. Tune in for a masterclass in fabric technology that proves keeping dry is equal parts chemistry, engineering, and outdoor know-how!Shortcuts:00:00 - Intro00:45 - Another Excuse for Ben to Geek Out...02:06 - Waterproof, Water-Resistant, and Water-Repellant03:55 - Maintaining Realistic Expectations06:23 - Waterhead and Hydrostatic Head08:49 - Coatings and Laminations11:37 - Hydrophilic Coatings and Preventing Hydrolysis13:01 - PE Vs PU Coatings13:53 - Siliconised Fabrics15:21 - Laminated Fabrics16:23 - Durable Water Repellant (DWR)18:20 - Canvas Vs Polyester27:14 - Re-Waterproofing31:01 - Another Geek-Out Done! Join the conversation over on our Facebook group:https://www.facebook.com/groups/snowysHead to snowys.com.au for all your gear needs:https://www.snowys.com.au
