Morphology
The noun phrase is compositionally built: it denotes the acetate (acetylated) form of cellulose, i.e. a material/derivative made from cellulose used for fibers and films. This follows a regular material-noun composition pattern (X + acetate = acetate of X) that is cross-linguistically common, so a B1 learner who knows both constituents can infer the basic meaning.
Etymology
Cellulose acetate comes from a simple idea: plant cellulose, the natural fiber in wood and cotton, is treated with acetic acid, a substance like vinegar, to make acetate, a flexible, plastic-like material. That's why cellulose acetate is used to make film, cloth fibers and eyeglass frames today.
