The First Ever Liquid- And Water-Resistant Shirt
Waterproof fabrics are fabrics that are inherently, or have been treated to become, resistant to penetration by water and wetting. The term "waterproof" refers to conformance to a governing specification[1] and specific conditions of a laboratory test method. They are usually natural or synthetic fabrics that are laminated to or coated with a waterproofing material such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, fluoropolymers, and wax. Treatment could be either of the fabric during manufacture or of completed products after manufacture, for instance by a waterproofing spray. Examples include the rubberised fabric used in Mackintosh jackets, sauna suits and inflatable boats. They are even used for footballs and glasses.
Fabric construction which directs water away from the body, rather than membranes, coatings or laminates, can be used to keep the wearer dry. This means that perspiration can be moved away from the body more effectively, as both liquid water and water vapour can be directed. These are directional fabrics such as Nikwax Analogy and FurTech, which are also breathable in the conventional sense (although these examples are actually a combination of two different fabrics, a directional "pump" layer underneath a distinct windproof and water resistant outer layer, and while effectively completely waterproof against rain they would fail a strict hydrostatic head test.
A university sophomore named Aamir Patel invented what he believes to be the first ever liquid- and stain-resistant t-shirt-he calls it the Silic t-shirt. The sprays which are available on the market that claim to guard apparel inside the same manner without a doubt comprise very dangerous materials. these products warn that if ingested may also reason most cancers and birth defects. different complaints consist of the sprays converting the feel of the cloth and no longer being able to last more than one wash cycle. The Silic shirt uses nanotechnology and is made with 4-way stretch polyester.
