Morphology

acid + dye

The compound is compositionally built from 'acid' and 'dye' — a dye that is acidic or used with acids — so a B1 learner who knows both words can infer the general meaning. Although the full technical definition (ion behavior, fiber chemistry) is specialized, the core concept 'a kind of dye related to acid' is transparently derivable from the constituents.

Etymology

Acid dye is named for how acid and dye work together: dyers put these dyes into slightly 'acid' water so the color can stick to wool and silk. That's why the name shows how the dye works and why it is used for protein fibers.
