What is Hydrophobic Down? 5 Benefits of Water Resistant Down

Web25 nov. 2024 · Hydrophobic down is goose or duck down that has been treated with a water-repelling chemical to make it less vulnerable to moisture. Down is naturally hydrophobic but once it is turned into insulation for clothing or sleeping bags it is susceptible to clumping if it gets wet. Clumping is bad. In industry, super-hydrophobic coatings are used in ultra-dry surface applications. The coating causes an almost imperceptibly thin layer of air to form on top of a surface. Super-hydrophobic coatings are also found in nature; they appear on plant leaves, such as the Lotus leaf, and some insect wings. The coating can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and … Web1 jan. 2016 · The degree to which a surface either attracts or repels water can be termed, respectively, the hydrophilicity or the hydrophobicity of that surface.
