Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether - polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont . [ 1 ] [ 2 ] [ 3 ]
Elastolefin is a fiber composed of at least 95% (by weight) of macromolecules partially cross-linked, made of ethylene and at least one other olefin.When stretched to one and a half times its original length, it recovers rapidly to its original length.
A still more popular use of polyurethane in textiles is in the form of spandex, also known as elastane or by DuPont's brand name Lycra. Polyurethane fibers in the form of spandex can stretch up to 600% and still return to their original shape. Spandex is spun with other fibers, such as cotton, nylon, or polyester, to create stretchable fibers ...
Elastic fibers stain well with aldehyde fuchsin, orcein, [16] and Weigert's elastic stain in histological sections.. The permanganate-bisulfite-toluidine blue reaction is a highly selective and sensitive method for demonstrating elastic fibers under polarizing optics.
Made with recycled nylon and elastane, this piece offers a soft, stretchy feel, along with underwire support for gentle shaping and coverage. The four-row hook-and-eye will ensure maximum ...
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus (E) and high failure strain compared with other materials. [1]
A lycra jacket. Stretch fabric is a synthetic fabric that stretches. Stretch fabrics are either 2-way stretch or 4-way stretch. 2-way stretch fabrics stretch in one direction, usually from selvedge to selvedge (but can be in other directions depending on the knit). 4-way stretch fabrics, such as spandex, stretches in both directions, crosswise and lengthwise.

Elasterell (officially "elasterell-p") is an alternative to the generic term "polyester" for a specific subgroup of inherently elastic, multicomponent textile fibers. [1]The Federal Trade Commission (FTC) in November 2002 issued a final rule which establishes the name. [1]
