Flax fiber / linen
Definition
Flax fibre is a bast fibre obtained from the stem of the flax plant (Linum usitatissimum); spun and woven, it produces linen, one of the oldest textiles in continuous use. Production involves harvesting by pulling or cutting, then retting — bacterial decomposition of the pectin binding the fibres — followed by scutching and heckling to separate long line fibres from short tow. Linen is strong, absorbent, quick-drying and biodegradable in weeks when buried, and is marketed as a more eco-friendly alternative to synthetic fibres and to water-intensive cotton; chemical retting is faster than natural retting but typically more harmful to the environment and to fibre quality.

Overview
What it means
Linen's sustainability case rests on rain-fed cultivation (notably in Western Europe), low irrigation and pesticide needs relative to cotton, durability and end-of-life biodegradability — but processing choices (retting method, finishing chemistry) and transport shape its actual footprint.
How it is used
Used in apparel and home textiles, technical composites, and sustainability comparisons of fibre choices in fashion.
Why it matters
As fashion confronts synthetic-fibre pollution and cotton's water demand, linen is the leading established natural alternative with an industrial supply base. **Note:** Quantified comparative claims (water, pesticides) vary by study; editors should verify specific figures against current LCA literature at publication.
