Gore-Tex is W. L. Gore & Associates's trade name for waterproof, breathable fabric membrane. It was invented in 1969. Gore-Tex blocks liquid water while allowing water vapor to pass through and is designed to be a lightweight, waterproof fabric for all-weather use.
Durable water repellents are commonly used in conjunction with waterproof breathable fabrics such as Gore-Tex to prevent the outer layer of fabric from becoming saturated with water. This saturation, called 'wetting out,' can reduce the garment's breathability (moisture transport through the breathable membrane) and let water through.
The first report of using Gore-Tex to make waterproof, breathable garments appeared in a market report, April 13, 1972. [5]: 107 The manufacturing process was patented in 1972. [16] The first commercial sales of Gore-Tex were made in 1976 when Early Winters, Ltd., began making and selling Gore-Tex tents. The next year Early sold Gore-Tex rainwear.
Gabardine Closeup view of gabardine fabric. Gabardine is a durable twill worsted wool. It is a tightly woven waterproof fabric and is used to make outerwear and various other garments, such as suits, overcoats, trousers, uniforms, and windbreakers. Thomas Burberry created the fabric in the late 1870s and patented it in 1888. [1]
Drop of water on 100% polyester textile. Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through. Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications.
Air permeability is the ability of a fabric to allow air to pass through it. While air permeable fabrics tend to have relatively high moisture vapor transmission, it is not necessary to be air permeable to be breathable. Moisture Vapor Transfer (MVT) in waterproof fabrics occurs by two processes:
Tyvek's properties—such as being difficult to tear but easily cut, and waterproof against liquids while allowing water vapor to penetrate—have led to it being used in a variety of applications. Tyvek is often used as housewrap , a synthetic material used to protect buildings during construction, or as personal protective equipment (PPE).
Unlike most "waterproof breathable" fabrics, Analogy can pass out liquid water as well as vapour. Unlike a conventional waterproof fabric, Analogy would fail a hydrostatic head test (if used to seal the bottom of a tube containing water, only a very short column could be supported). However, like fur, Analogy causes water to flow away from the ...
