TECHNICAL DATA SHEET
Elastane-Covered (Gimped) Yarn
Elastane-Covered (Gimped) Yarn — Activewear (leggings, sports bras) · swimwear · stretch-denim weft · socks/hosiery · seamless/shapewear · waistbands/elastics. Adds high stretch + recovery to an inelastic yarn; the sheath protects the core from abrasion/heat/chemicals; DCY gives full coverage and balanced torque.
| Construction | Pre-tensioned elastane core wrapped in polyester/nylon filament · SCY · DCY · ACY · core-spun |
|---|---|
| Process | Covering/wrapping; core denier typically 20–70D — on request |
| Luster | Varies with the sheath yarn (semi-dull typical) |
| Yarn family | Elastane-Covered (Gimped) Yarn |
| Typical use | Activewear (leggings, sports bras) · swimwear · stretch-denim weft · socks/hosiery · seamless/shapewear · waistbands/elastics |
| Strength | Adds high stretch + recovery to an inelastic yarn; the sheath protects the core from abrasion/heat/chemicals; DCY gives full coverage and balanced torque. |
| Watch for | Single-cover (SCY) can show residual torque and grin-through under stretch — eliminated by DCY; chlorine/UV resistance comes from the spandex grade, not the covering. |
