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)
