Find out moreLycra fabric is the brand name for elastane material. This is a general term for any textile where elastane yarns have been used in its construction. It is strong and flexible, like rubber. It does not lose its shape or stretch when pulled and it has an excellent recovery.
Lycra material can also be known as Spandex. It is a polyurethane based synthetic fiber, which has an exceptionally high degree of stretch and rapid recovery. Initially developed in 1958, it was created to replace latex rubber as a stretching agent in clothing. It is usually combined with other fibers, such as cotton or polyester and it is used in a huge variety of products – from fashion to medical equipment.
Lycra is made up of a long chain polymer called polyurethane. This is produced by reacting a polyester with a disconsolate. The polymer is made into a fiber using a dry spinning process.
The unique stretchy attribute of Lycra fibers is a result of the yarn’s chemical composition. A block copolymer process produces them. The long flexible blocks of polyurethane alternate with shorter, more crystalline segments. The longer portions provide the sketchiness and the crystalline segments create re-enforcing points. This is what makes it such a strong and durable fiber.
Lycra is mainly used in the fashion and sportswear industries. It is a popular fiber choice for women’s undergarments and lingerie. It can also be used for homeware products, such as fitted sheets, or anything else that requires a degree of flexibility.
Because it doesn’t get damaged by sunlight, sweat or detergents, it is a very durable material. These are key reasons why it is such a popular textile for sportswear, activewear, and swimwear.
Lycra is always combined with other fibers, but the amount of Lycra used is different for every end use. For fashion items, as little as 2% Lycra is added to give the garment shape retention, drape, movement, and form. High-performance garments – such as those used in activewear – require more Lycra fabric. These can contain up to 20 – 30%.
Lycra material is a flexible and forgiving fiber. When combined with other fabrics, it can provide security, comfort, and support.
