Nukuvuga ko ubu bwoko bwa fibre bushobora kuramburwa byoroshye, ariko nyuma yo gukira, burashobora kwizirika cyane hejuru yumubiri wumuntu hamwe nimbaraga nke zihuza umubiri. Lycra fibre irashobora gukoreshwa nigitambara icyo aricyo cyose kandi izwi nka fibre "nshuti". Ubwiza buhebuje buzwi na bagenzi babo. Imyenda iyo ari yo yose ikoresha Lycra izamanikwa hamwe na tagi ya mpandeshatu, ibaye ikimenyetso cya ubuziranenge.
Lycra ni izina ry'ubucuruzi kuri Invista, isosiyete nini ya fibre nini ya polymer nini ku isi (yahoze ari - ishami rya DuPont, ryaguzwe na Koch Industries kuri miliyari 4.4 z'amadolari mu 2004). Invista ifite isoko ryihariye mumasoko ya spandex, kandi Lycra ni kimwe nudodo twose twa spandex. Irasimbuza rwose umugozi wa reberi gakondo ya elastique, kandi Lycra nikintu cyingenzi mubyambarwa hamwe nibisabwa bidasanzwe nka gymnastique na swimwear.

Laika ntabwo ikoreshwa cyane mumyenda ya buri munsi, ariko kandi nk'inyamanswa mu kwerekana imideli ikunzwe na kaleidoscope. Laika yigeze kwitwa fibre yubumaji nabantu barishimye cyane.
