Spandex wordt over het algemeen niet alleen gebruikt, maar een kleine hoeveelheid wordt in de stof gemengd. Dit soort vezel heeft zowel rubber- als vezeleigenschappen. Het is gemakkelijk om 25 2500 denier zijde van verschillende diktes te spinnen. Daarom wordt het veel gebruikt om elastische vlechten te maken, zoals sokmond, meubelhoes, skikleding, sportkleding, medische stoffen, riemen, kwartiermakeruitrusting, elastische onderdelen van ruimtevaartkleding, enz. Omdat mensen nieuwe eisen stellen aan stoffen, zoals lichtgewicht, comfortabele pasvorm en zachte textuur, neemt ook het aandeel spandex-stoffen met een laag denier in synthetische vezelstoffen toe.
