TECHNICAL DATA SHEET
Polyester Rib Knit (1x1 / 2x2)
| Weight | 160–300 g/m² |
|---|---|
| Composition | 100% polyester (elastane-free); stretch comes from the structure. |
| Knit type | Rib (1x1 / 2x2) · Rib |
| Use class | Everyday |
| Stretch | Mechanical stretch |
| Knit | A 1x1 or 2x2 rib produced on opposed needle rows; pronounced vertical channels on both faces, a reversible double-face fabric. |
| Hand | Clear vertical channels, full and springy; compresses and opens crosswise, self-recovering; edges don’t curl. |
| Typical use | Collar/cuff/waistband trims · hem & cuff ribbing · ribbed tops |
| Strength | A non-curling channelled structure that hugs the body with high crosswise stretch and natural recovery. |
| Watch for | Without elastane, heavy weights can slacken over repeated stretching; lengthwise stretch is low. |

Typical technical ranges
| Weight tolerance | ±5% (typical); ±5–7% may apply on heavy/dense rib and elastane-blended variants |
|---|---|
| Width | Relaxed open width typically ~70–190 cm; tubular width typically 30–90 cm (Ø). Because rib contracts strongly widthwise, the relaxed width is markedly narrower than off-machine width and is highly sensitive to relax/tension state at measurement |
| Shrinkage (wash) | Post-wash typically ±5% in length/width (length may show a small positive growth). Due to widthwise recovery, rib can show higher dimensional change in WIDTH than single-jersey; under-set goods may reach −6 to −7% in width, while good heat-setting brings it toward ±3% |
| Color fastness | Wash ≥4, rubbing (dry) ≥4 / (wet) ≥3–4, light ≥4–5 (grey/blue scale, min). Typically good for disperse-dyed PES; on dark/bright shades wet rub may sit at the lower bound due to sublimation/migration |
| Abrasion / pilling | Martindale typically ~20,000–40,000+ cycles; pilling typically grade 3–4 / 4 (ISO 12945), dropping toward 3 on textured/bulky yarn. Plain rib face pills relatively well; textured/bulky yarn or surface fuzz pushes it toward the lower bound |
| Gauge / yarn | Typical machine gauge E14–E24 (coarse cuff/collar rib E14–E18; standard cuff/collar rib E18–E22; fine sport rib up to E24). Yarn typically 75–150 denier PES (DTY textured), 50–75 denier on finer builds; elastane variant adds ~20–40 denier spandex |
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.
