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.

The only composite yarn in the catalogue, and not a single construction: production runs five variants — 50/72 and 75/72 sheaths over 20, 30 and 40 denier elastane cores. Total denier is the sheath plus the drafted core, which is why 75/72 + 20D lands at 82–85 denier and +40D at 88–90. As the elastane share rises, stretch and recovery rise with it, tenacity (2.8–3.9 cN/dtex) stays below plain DTY, and boiling-water shrinkage reaches 7.5 — the heat-setting window has to be narrowed accordingly. Spin finish running as high as 2.9 is a natural consequence of the covering process.

Watch forSingle-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.
