bristle material
also called fibre
The fibre the working bristles of a bristle cleaning tool are made of — PPN (polypropylene), coir (coconut fibre), bassine (palm fibre), natural bristle (the 'pure bristle' hog/horsehair of a fine brush), nylon, steel wire, or a union/mixed fibre. It is the EXCLUSIVE differentia of the Brushware family and is distinct from the spine `material` (which states the handle/stock material — wood or metal): a real broom listing states BOTH ('wood handle / coir bristle'), so the bristle fibre is its own functional slot, not a value of `material` (A11-clear). Concern facet (axis-eligible — a brush range genuinely sold in PPN and natural-bristle grades is a legitimate seller family).
Bristle material is answered with one word chosen from the bristle materials list — the same word shared across every product that uses it.
It belongs to facet — one facet of a product.
