Kurambura umwenda wimyidagaduro yumugore mwibara ryiza.Byakozwe na rayon, nylon na spandex fibre, ifatika kandi ihendutse.
Spandex ni umwenda wubukorikori uhabwa agaciro kubworoshye.Bitandukanye n’imyemerere ikunzwe, ijambo "spandex" ntabwo ari izina ryirango, kandi iri jambo rikoreshwa muri rusange ryerekeza ku mwenda wa polyether-polyurea copolymer wakozwe hamwe nuburyo butandukanye bwo gukora.Amagambo spandex, Lycra, na elastane ni kimwe.
Kimwe nizindi polymers, spandex ikozwe mugusubiramo iminyururu ya monomers ifashwe hamwe na aside.Kera mubikorwa byiterambere rya spandex, byamenyekanye ko ibyo bikoresho birwanya ubushyuhe bwinshi, bivuze ko imyenda izwi cyane yubushyuhe nka nylon na polyester itezimbere iyo ihujwe nigitambara cya spandex.
Kurambura kwa Elastane byahise bituma bifuzwa kwisi yose, kandi gukundwa kwiyi myenda biracyakomeza.Iraboneka muburyo bwinshi bwimyenda kuburyo buri muguzi afite byibura ingingo imwe yimyenda irimo spandex, kandi ntibishoboka ko iyi myenda izwi cyane izagabanuka mugihe cya vuba.
