Buying Guide: Nylon Spandex Knit Fabric

What to consider when choosing nylon spandex knit fabric

  • Blend and stretch: Most garments benefit from an 80% nylon / 20% spandex blend for a balance of strength and flexibility. Higher spandex content increases elasticity but can alter shape retention.
  • Width and yardage: Wider fabrics (58–63 inches) reduce seams and waste for full-coverage patterns, especially in swimwear. Confirm whether fabric is cut in continuous pieces or sold as per-yard sections.
  • Weight and drape: Lighter fabrics dry quickly and feel breathable, ideal for swimwear. Heavier knits (200 gsm and above) offer more structure for leggings or dancewear.
  • Care and durability: Look for colorfastness and resistance to chlorine, salt, oils, and sunscreens. Repeated washing should not deform the fabric.
  • Application fit: For form-fitting garments, choose fabrics with higher elasticity and recovery. For looser silhouettes, a moderate stretch may suffice.
