Morphology
The phrase is a straightforward chemical compound formed by combining 'cellulose' (a plant polymer) with 'triacetate' (an acetate-derived form), so its meaning—a form of cellulose that is triacetylated/modified—is directly compositional. Although the item is technical and domain-specific, a learner who knows both constituents can infer it denotes a cellulose-based triacetate polymer used for applications like membranes.
Etymology
Cellulose triacetate is named from cellulose, the strong plant fiber, and triacetate, which means three acetate groups attached to it. Those acetate parts turn the plant fiber into a firm film that is 'slow to burn', so it was used as a safer base for photographs and old movie film.
