A synthetic fiber obtained by spinning long-chain synthetic polymers that mainly contain polyurethane, a polymer with urethane bonds (-NHCOO-). It is extremely elastic and is known by the generic name of spandex. It was developed in Germany and Japan (by Toshio Hoshino) around 1940, and was named Perlon U and Pollan, respectively. In the United States, DuPont began industrial production in 1960 under the brand name Lycra, and Luber began industrial production under the brand name Vilen. In addition to its elasticity, it has good abrasion and chemical resistance, and is easy to dye. It has a wide range of uses in clothing, including women's underwear such as brassieres and corsets, sportswear, supports, and bandages.

ウレタン結合 (-NHCOO-) をもつ重合体ポリウレタンを主として含む長鎖状合成高分子を紡糸して得られる合成繊維。きわめて伸縮性に富み,スパンデックスの一般名で知られる。 1940年頃ドイツ,日本 (星野敏雄) で開発され,それぞれパーロンU,ポルランと名づけられた。またアメリカでもデュポン社が 60年ライクラの商品名で,ルーバー社がバイレンの商品名で,相次いで工業生産を始めた。伸縮性のほか耐摩耗性,耐薬品性がよく,染色性も良好。衣料用として用途が広く,ブラジャー,コルセットなどの婦人用下着,スポーツ着,サポーター,包帯などに使われる。
