Linen Yarn for
Sustainable Fashion.
Linen is the only mainstream textile fibre that is demonstrably net-positive across every major environmental metric: zero irrigation in European growing regions, no synthetic pesticides required, full-plant utilisation (seeds, straw, shive), and complete biodegradability at end of life within 2–3 years under composting conditions.

Quick Read
First-pass technical cues
GSM Range
Lightweight sustainable basics (tanks, tees, summer shirts): 120–155 GSM
Yarn Count
Lightweight summer garments: 40–60 Nm wet-spun (fine, low hairiness)
Construction Options
Plain weave (balanced): Standard for sustainable shirts and dresses — maximises breathability, lowest processing-chemical requirement
Shrinkage
Untreated greige fabric, first wash (40°C): 4–7% warp, 2–4% weft
GSM Range
• Lightweight sustainable basics (tanks, tees, summer shirts): 120–155 GSM • Core sustainable casualwear (shirts, blouses, dresses): 155–190 GSM • Outerwear and structured sustainable pieces: 200–260 GSM • Sustainable workwear and durable everyday: 180–220 GSM
Yarn Count
• Lightweight summer garments: 40–60 Nm wet-spun (fine, low hairiness) • Mid-weight casualwear: 24–40 Nm — the commercial sweet spot for sustainable brands • Heavier structured pieces: 12–22 Nm • Sustainable blends (linen/organic cotton, linen/TENCEL): 28–45 Nm depending on blend composition
Construction Options
• Plain weave (balanced): Standard for sustainable shirts and dresses — maximises breathability, lowest processing-chemical requirement • Twill weave: Better drape for sustainable trousers and structured dresses; 10–15% heavier than equivalent plain weave • Single jersey knit (blended, 55% linen / 45% organic cotton): For sustainable T-shirts and casual tops; requires blend for workable stretch • Waffle/honeycomb: Texture interest for sustainable loungewear; high surface area improves moisture management • Canvas (tightly woven, high thread count): Sustainable tote bags, accessory pieces — exceptional durability
Shrinkage
• Untreated greige fabric, first wash (40°C): 4–7% warp, 2–4% weft • Pre-washed (enzyme-scoured + sanforised): 1–2% residual — specify for cut-and-sew • Note: line drying at 30°C wash significantly reduces shrinkage versus tumble drying — important for consumer care instruction copy
Pilling Resistance
• Grade 4–5 (ISO 12945-2 Martindale, 2,000 cycles) on woven constructions • Knitted linen blends: Grade 3–4 depending on blend partner; linen component's low elasticity reduces pill formation
Colorfastness
• Natural undyed (ecru/greige): No colorfastness concern — best sustainability option, zero dye-process chemicals • Reactive-dyed, enzyme pre-scoured: ISO 4/4-5 wash, 4–6 light, 4 wet rub • Low-impact fibre-reactive dyes: Preferred for sustainable fashion; no heavy metals, AZO-free, compatible with GOTS certification
Tensile Strength
• Dry: 35–62 cN/tex (highest of any natural fibre in commercial textile production) • Wet: 20% HIGHER than dry tensile strength — linen is one of the only fibres that strengthens when wet
MOQ Guidance
• Stock linen greige (India-converted from European tow): 200–300 metres per colourway • Natural/undyed ecru programmes: lowest MOQ, 150–200 metres due to no dye-batch constraints • European mill custom construction: 300–500 metres minimum per construction/colour
Common Questions
Linen for Sustainable Fashion — answered.
Linen for Sustainable Fashion — answered.
Organic cotton addresses pesticide and GMO concerns but does not solve water consumption — organic cotton still requires 8,000–15,000 litres per kg of fibre in irrigated growing regions. European linen requires zero irrigation (rain-fed in Atlantic-climate growing regions) and approximately 6.4 litres per tonne in processing. On water footprint alone, linen is 1,000–3,000× more water-efficient than organic cotton. Linen also outlasts cotton by 3–5× in wear tests, meaning fewer garments produced per unit of customer need over a decade. The two certifications most relevant to distinguishing linen's advantage: European Flax (no irrigation, no pesticides, field-level trace) versus GOTS organic cotton (pesticide-free farming, no irrigation guarantee).
