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. It is composed of expanded PTFE (ePTFE), a stretched out form of the PFAS compound polytetrafluoroethylene (PTFE).
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a layered object or material assembled using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used.
Oilskin is a waterproof cloth used for making garments typically worn by sailors and by others in wet areas. The modern oilskin garment was developed by a New Zealander, Edward Le Roy, in 1898. Le Roy used worn-out sailcloth painted with a mixture of linseed oil and wax to produce a waterproof garment suitable to be worn on deck in foul-weather conditions. Oilskins are part of the range of protective clothing also known as foul-weather gear.
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable due to practical or ethical concerns. Artificial leather is known under many names, including leatherette, imitation leather, faux leather, vegan leather, PU leather (polyurethane), and pleather.
Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.
Darlexx, a product of the Shawmut Corporation, is a warp knit fabric laminated to a monolithic film. It is a sports performance fabric used in gloves, boots, wet suits, ski apparel, clean rooms, and in medical applications. It was designed to keep a person "warm when the environment is cold and cool when the environment is hot" and is breathable, windproof, and waterproof.
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 and specific conditions of a laboratory test method. They are usually natural or synthetic fabrics that are laminated or coated with a waterproofing material such as wax, rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, or fluoropolymers. Treatment could be either of the fabric during manufacture or of completed products after manufacture, for instance by a waterproofing spray. Examples include the rubberized fabric used in Mackintosh jackets, sauna suits, and inflatable boats.
Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic). Most factory-applied treatments are fluoropolymer based; these applications are quite thin and not always effective. 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 and let water through. As the DWR wears off over time, re-treatment is recommended when necessary. Many spray-on and wash-in products for treatment of non-waterproof garments and re-treatment of proofed garments losing their water-repellency are available.
Sympatex is a type of fabric that is branded as waterproof but "breathable", made or licensed by Sympatex Technologies GmbH a company founded in 1986. The fabric features a waterproof, windproof and breatheable membrane that is laminated to fabrics either on its inner surface or sandwiched between two fabric layers. The latter system offers greater durability, by better protecting the integrity of the Sympatex layer from abrasion to both the outside and the inside of the garment.
Windstopper is a windproof breathable fabric laminate made by W. L. Gore & Associates. One of its most common applications is a lamination with polar fleece, to compensate for fleece's lack of wind resistance.
A tuilik is an Inuit watertight jacket, used when paddling a kayak. It is sealed at the face, at the wrists and around the cockpit coaming. In this way the paddler can capsize and come back upright without getting wet, and without getting any water into the kayak.
Ventile, is a registered trademark used to brand a special high-quality woven cotton fabric first developed by scientists at the Shirley Institute in Manchester, England. Originally created to overcome a shortage of flax used for fire hoses and water buckets, its properties were also useful for pilots' immersion suits, but expensive and leaky if exposed to sweat or oils.
Breathability is the ability of a fabric to allow moisture vapor to be transmitted through the material.
OMNOVA Solutions, Inc. is a global manufacturer of laminates, performance films and coated fabrics. OMNOVA was founded in 1999 when GenCorp, Inc. spun off its Decorative & Building Products and Performance Chemicals businesses into a separate, publicly traded company. OMNOVA's world headquarters is located in Beachwood, Ohio; with additional sales, manufacturing and distribution locations throughout Europe and Asia.
In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context.
Waxed cotton is cotton impregnated with a paraffin or natural beeswax based wax, woven into or applied to the cloth. Popular from the 1920s to the mid-1950s, the product, which developed from the sailing industry in England and Scotland, became commonly used for waterproofing. It has been replaced by more modern materials but is still used by the country sports community. There are two main drawbacks: waxed fabric is not very breathable, and it tends to be heavier and bulkier than modern synthetic waterproof materials.
Páramo Directional Clothing is a British outdoor clothing company. It was founded by Nick Brown, who also started the Nikwax waterproofing products company.
Oilcloth, also known as enameled cloth or American cloth, is close-woven cotton duck or linen cloth with a coating of boiled linseed oil to make it waterproof.
PVC clothing is shiny clothing made from the plastic polyvinyl chloride (PVC). PVC plastic is often called "vinyl" and this type of clothing is commonly known as vinyl clothing. PVC is sometimes confused with the similarly shiny patent leather.
