General
- Spandex or
elastane is a synthetic fiber known for its exceptional
elasticity.
- Elastane
fibres, better known under their trade names, Lycra and Dorlastan,
represent a further high point in the development of man-made
fibres.
- Invented in
1937 in Germany, elastane has properties not found in nature, the
most important being an extraordinary elasticity.
- The most
famous brand name associated with spandex is Lycra, a trademark of
Invista.
- Spandex is a
block copolymer of polyurethane and polyethylene glycol.
Process
- Spandex
fibers are produced in four different ways including melt
extrusion, reaction spinning, solution dry spinning, and
solution wet spinning.
- All of the
methods include the initial step of reacting monomers to produce
a prepolymer. Once the prepolymer is formed it is reacted
further in various ways and drawn out to produce a long fiber.
- The
solution dry spinning method is used to produce over 90% of the
world's spandex fibers.
Properties
- Compared
to rubber, elastane has both greater tear resistance and
durability and a tension capacity two or three times greater,
at a third of the weight.
- Elastane
has the highest stretch tension of all textile raw materials.
- Elastane
fibers guarantee a high degree of comfort combined with great
freedom of movement.
-
Elastane is not sensitive to transpiration, make-up,
cosmetics, sun cream or sea water.
