Microplastics
Material-class model assumption
Cashmere is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
Natural Fiber
Cashmere clothing: health and sustainability score
Cashmere is a specialty animal fiber with defined labeling requirements. “Cashmere feel” does not establish cashmere content; look for the actual named percentage.
Where it shows up
For knitwear, compare the cashmere share, other fibers, construction and care. Price or softness alone is not verification of fiber identity.
What the evidence supports
The FTC’s wool labeling guidance distinguishes cashmere from other wool and specialty fibers. The fiber name is not a finished-article chemical certification.
What remains unknown
The composition label does not establish animal-welfare verification, fiber quality, dye chemistry or durability of the exact sweater.

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 Cashmere. Product-level water, stain, or performance finishes can still change PFAS risk.
Half-life and biodegradability
Material-class model assumption
Cashmere has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Fiber shedding
Material-class model assumption
Cashmere has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Manufacturing energy
Material-class model assumption
Cashmere carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.

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