Interlock (Double-Knit Polyester)
| Weight | 160–250 g/m² (4.7–7.4 oz/yd²) In family: 85–250 g/m² · 4 fabrics |
|---|---|
| Composition | 100% polyester double-knit; cotton and elastane blends also exist. |
| Knit type | Interlock (double-knit) · Sport & Technical |
| Use class | Everyday |
| Stretch | Mechanical stretch |
| Knit | A double-knit where both faces’ loops interlock on two needle beds; identical faces (symmetric), flat, smooth. |
| Hand | Fuller, more stable and opaque than single jersey; both faces smooth, draping but bodied; no curling. |
| Typical use | Polos/tees · sport tops/joggers · fitted dresses · babywear |
| Strength | A double-knit that is more stable, opaque and durable than single jersey — both faces usable. |
| Watch for | Thicker/heavier than jersey at equal weight; not ideal for very thin summer pieces; stretch (elastane-free) is more limited than jersey. Same structure as the Interlock family. |
Width, gauge, finishing options and test standards are shared on request.
Typical technical ranges
| Weight tolerance | Typically ±5%; in very light (85–120 g/m²) jersey/mesh constructions may run to ±6–7% in practice. Spandex relaxation/tension affects GSM |
|---|---|
| Width | Open width (finished): typically 150–190 cm; tubular: typically 90–180 cm depending on supply form (varies with cylinder diameter/machine and final set width) |
| Shrinkage (wash) | After wash, length/width: typically −3% to −6%; ≤ ±3% achievable with good heat-set/compaction. Single jersey moves more than balanced interlock/rib; spandex recovery can increase length change |
| Color fastness | Wash 4–5; rubbing dry 4–5, wet 3–4 (deep/bright & migration-prone shades may drop to 2–3); light 4–5; perspiration typically 4–5. Wet rub & deep/bright shades are the weakest link; reductive clear (RC) quality is decisive |
| Abrasion / pilling | Martindale abrasion: typically ~15,000–40,000+ cycles (tight piqué/double-knit high, light mesh/jersey lower); pilling: typically 3–4 (near 4 on smooth filament; texturized/microfiber/brushed surfaces can sit at 2–3; anti-pill finish can lift to 4) |
| Gauge / yarn | Machine gauge: typically E24–E32 (E36–E40 for very fine constructions); yarn: typically 50–150 denier texturized/microfilament PES. Notation is denier/filament-count (e.g. 50/72, 75/72, 100/144, 150/288) — higher filament count = lower dpf = microfilament/soft hand. Spandex variants add base PES + spandex (e.g. 20–40 denier) |
