TECHNICAL DATA SHEET
Polar Fleece
| Weight | 180–400 g/m² |
|---|---|
| Composition | 100% polyester (recycled rPET versions common). |
| Knit type | Polar fleece · Polar Fleece |
| Use class | Outer / structured |
| Stretch | Mechanical stretch |
| Knit | After the circular-knit ground, the face(s) are raised and sheared on a brushing machine; usually double-brushed, soft napped texture. |
| Hand | Soft, napped, lofty; a raised, warm-feeling surface, medium-soft drape. |
| Typical use | Fleece jackets/tops · inner lining/mid-layer · blankets/home textile · beanies-gloves |
| Strength | The economical, durable classic insulator — high warmth for its weight and fast drying. |
| Watch for | Low-grade/unfinished fleece can pill and flatten over time; it is wind-permeable, so wind protection as an outer is limited. |

Typical technical ranges
| Weight tolerance | ±5% (typical); on raised/napped fleece ±5–7% is more realistic, up to ±7% on light micro-fleece |
|---|---|
| Width | Open width ~150–190 cm (typically 160–180); tubular ~70–95 cm. Varies with machine diameter/cut, weight and stenter draw |
| Shrinkage (wash) | Length/width ~±2–4% (typical after proper heat-set); may reach ~5% in length if setting/finishing is weak. A ≤±3% target is common |
| Color fastness | Wash 4–5; rubbing (dry) 4–5, (wet) 3–4; light 4–6 (typical disperse-dyed PES). Minimum ~4 targeted; wet rub drops to the low end on deep/bright shades |
| Abrasion / pilling | Pilling 2–3 (raw/unfinished) → 3–4 with anti-pill shearing/finish, up to 4 in good cases. Martindale abrasion is usually not reported for fleece; if reported, ~15,000–30,000 cycles order of magnitude (construction/yarn dependent) |
| Gauge / yarn | Machine gauge ~E18–E24 (typically E20–E22; heavy/lofty polar down to E16–E18); yarn typically 100–300 denier textured (DTY) PES (coarser denier or plied feed for nap/loft; ~75 denier microfilament on micro-fleece) |
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.
