Microplastics
Penalty 0/100 - weighted impact 0
Silk is recorded as Natural Fiber with no listed microplastic polymer, so it does not add a microplastic-source penalty.
Natural Fiber
Silk clothing: health and sustainability score
A natural protein fiber from silkworms. Biodegradable and luxurious, but sustainability depends on production methods. Peace silk (cruelty-free) options available.
Score drivers
Greener Closet scores materials from several penalty inputs. The same material can be reasonable in one product and weak in another, but these are the default drivers behind the base material record.
No default penalty
PFAS uncertainty
Penalty 0/100 - weighted impact 0
MaterialsDB does not apply a base PFAS penalty to Silk. Product-level water, stain, or performance finishes can still change PFAS risk.
Half-life and biodegradability
Penalty 0/100 - weighted impact 0
Silk has no persistence penalty in MaterialsDB, which generally reflects better biodegradability than petroleum-based synthetics.
Fiber shedding
Penalty 0/100 - weighted impact 0
Silk has no default microfiber-shedding penalty in MaterialsDB. Garment construction and laundering still matter.
Manufacturing energy
Penalty 70/100 - weighted impact 7
Silk 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 Silk clothing shed microplastics?
Silk has no listed microplastic polymer in MaterialsDB, though garment construction and washing still affect fiber release.
Is Silk biodegradable?
Silk has no half-life penalty in MaterialsDB, which is a better biodegradability signal than petroleum-based synthetics.
How should I check a Silk blend?
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Silk is only one part of the garment.
