FAQ

Frequently Asked Questions

Acetate is a semi-synthetic material derived from cellulose (natural) but chemically processed.

Acetate is biodegradable under certain conditions, but recycling processes are limited compared to common plastics.

Triacetate has a higher degree of acetylation, making it more heat-resistant and less prone to wrinkling than regular acetate.

Yes, acetate fabrics are generally safe for clothing, though some people with sensitive skin might prefer natural fibres.
