Spandex Fiber Properties and Uses | Generated by AI
You’re referring to “氨纶” (ān lún) in Chinese — sometimes people also pronounce or write it informally as “安纶”.
氨纶 (Spandex / Elastane / Lycra) is a synthetic elastic fiber known for its exceptional stretchability.
Here’s a plain explanation:
- Chinese name: 氨纶
- Pinyin: ān lún
- English names: Spandex, Elastane, or Lycra (brand name)
- Composition: Made from polyurethane (a kind of polymer).
-
Features:
- Can stretch up to 5–8 times its original length and return to shape
- Soft, smooth, and resistant to sweat
- Usually blended with cotton, polyester, or nylon to make fabrics elastic
Common uses: Sportswear, leggings, yoga pants, swimsuits, underwear, and fitted T-shirts.
You also mentioned “涤纶” (dí lún) — that’s polyester. It’s a different fiber: less stretchy, more durable, and wrinkle-resistant.
So:
- 氨纶 = Spandex / Elastane (stretchy)
- 涤纶 = Polyester (smooth, durable, not stretchy)
