Microplastics
Material-class model assumption
Linen is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
Natural Fiber
Linen clothing: health and sustainability score
Linen is made from flax fiber. “Linen look” describes appearance and should not be treated as a fiber-content statement.
Where it shows up
For shirts or trousers, compare the actual linen share, weave, opacity and care. A linen-cotton blend and a linen-viscose blend are different compositions.
What the evidence supports
The EU textile definitions identify linen with flax, separating it from other plant and regenerated-cellulose fibers.
What remains unknown
The fiber name does not verify farming inputs, softening treatment, dyes, coating or whole-product environmental impact.
Primary sources

- Textile Fiber Rule (U.S. Federal Trade Commission)

How the model interprets this fiber
Greener Closet scores the disclosed share using the corresponding MaterialsDB record. Its factor defaults are model assumptions, not product testing, a factory life-cycle assessment or independently validated quantitative calibration.
No default penalty
PFAS uncertainty
Material-class model assumption
MaterialsDB does not apply a base PFAS penalty to Linen. Product-level water, stain, or performance finishes can still change PFAS risk.
Half-life and biodegradability
Material-class model assumption
Linen has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Fiber shedding
Material-class model assumption
Linen has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Manufacturing energy
Material-class model assumption
Linen carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.

Paste the full fabric label into the homepage checker. A 95% cotton, 5% elastane garment will not score the same as 100% cotton, and the checker handles those percentages.

Common questions
Does Linen clothing shed microplastics?
Linen has no listed microplastic polymer in MaterialsDB. Garment construction and washing can still release fibers.
Is Linen biodegradable?
Linen has no half-life penalty in MaterialsDB, which is a better biodegradability signal than petroleum-based synthetics.
How should I check a Linen blend?
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Linen is only one part of the garment.
