Finding opaque rayon
Opaque is a constraint on rayon, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Rayon is filed here as regenerated cellulose. One reason to open it is soft apparel drape. One reason to sample is care and shrinkage need sampling.
Judge opaque together with construction. Higher opacity can add weight or reduce breathability.
What not to assume
A opaque filter does not certify the cloth. dresses, blouses, linings are common places buyers test rayon, and some of those garments will reject this attribute.
Questions
- Does opaque rayon mean every listing qualifies?
- No. Open the fabric page. If the spec does not support the attribute, drop the card.
