TECHNICAL DATA SHEET
Polyester Stretch Interlock with Elastane
| Weight | 180–300 g/m² |
|---|---|
| Composition | Polyester base + elastane; typically 5–12% (from comfort to high recovery). Higher levels belong to warp-knit power nets, not interlock. |
| Knit type | Stretch interlock + elastane · Interlock |
| Use class | Sport |
| Stretch | 4-way stretch |
| Knit | Elastane fed/covered into the interlock double-knit; multi-direction stretch while keeping the stable twin faces. |
| Hand | Soft, fluid and elastic; body-hugging, snaps back when stretched; semi-matte smooth. |
| Typical use | Leggings · sports bras/bodysuits · yoga/performance tops |
| Strength | Strong multi-direction stretch and shape retention via elastane — ideal where compression is needed. |
| Watch for | Elasticity can fade with heat/chlorine over time; can sheer when stretched at low weights. |

Typical technical ranges
| Weight tolerance | ±5% (typical); may run ±5–7% on heavier/technical qualities |
|---|---|
| Width | Open width ~150–185 cm; tubular ~80–100 cm (varies with cylinder diameter and weight) |
| Shrinkage (wash) | Width/length ~−3% to −6% (typical, target ≤ ~5%); first-wash length may run slightly higher |
| Color fastness | Wash 4–5; rubbing (dry) 4–5, (wet) 3–4 (lower wet on deep/bright shades); light 4–6 (deeper shades higher) |
| Abrasion / pilling | Martindale ~20,000–40,000+ rubs (plain interlock, dense double-face structure); pilling ~3–5 (typically 4–5 on flat filament; textured/staple content or softener can drop a grade) |
| Gauge / yarn | Machine gauge ~E18–E28 (E20–E24 typical for mid–heavy 170–250 g/m²; fine sport interlock up to E28); yarn ~75–150 den DTY (50–75 D on fine qualities, 167–300 D on heavy) |
These ranges are industry-TYPICAL / indicative values based on construction and fiber, not Fersan's binding QC measurements. Exact values are confirmed per order, approved sample and lot-based QC report.
