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 ]
Joseph Clois Shivers Jr. (November 29, 1920 – September 1, 2014) was an American textile chemist who was based in West Chester, Pennsylvania, best known for his role in the structural development of Spandex, a thermoplastic elastomer, in the 1950s, while employed at DuPont. [1] Shivers was born in 1920 in Marlton, New Jersey.
1940 – Spectrophotometer invented, with impact on commercial textile dye processes. 1942 – First patent for fabric singeing awarded in US. [26] 1949 – Heinrich Mauersberger invents the sewing-knitting technique and his "Malimo" machine. 1955 – Research begins on multi-phase weft insertion.
Polyurea and polyurethane are copolymers used in the manufacture of spandex, which was invented in 1959. Polyurea was originally developed in automotive applications in the 1980s [2] [3] but other applications such as protecting tabletop edges followed. [4]
For example, though most of her clothes are made of non-plastic cotton and wool, some of her clothes are made of plastic fibers, like the spandex, polyester, and nylon in her activewear.
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.

Fibers invented between 1930 and 1970 include nylon, PTFE, polyester, Spandex, and Kevlar. Clothing producers soon adopted synthetic fibers, often using blends of different fibers for optimized properties. [100] Synthetic fibers can be knit and woven similarly to natural fibers. Synthetic fibers are made by humans through chemical synthesis as ...
