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]
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 ]
Sorona is DuPont de Nemours, Inc.'s brand of Triexta, a subclass of polytrimethylene terephthalate (PTT) [1] named and commercialized in 2000. [2] The fibers are soft and stain-resistant while exhibiting high strength and stiffness.
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.
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.

Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
A polyamide is a polymer with repeating units linked by amide bonds. [1]Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.
