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.
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.

Ester-based TPU in cases where oil and grease resistance is more relevant. When stable light colour and non-yellowing performance are required, aliphatic TPU based on aliphatic isocyanates is used. BASF has pioneered crosslinking during TPU transformation, made possible by adding liquid crosslinkers or using a solid granulated additive masterbatch.
It can be assumed that the animal skins were used for clothing throughout the human history, although in the ways that are primitive when compared to the modern processing, the earliest known samples come from Ötzi the Iceman (late 4th millennium BC) with his goatskin clothes made from leather strips put together using sinews, bearskin hat, and shoes using the deerskin for the uppers and ...
