Abstract
The invention relates to a brush which comprises a handle portion, a base portion formed with recesses for holding filaments or bristles, an insert which acts as holding means for holding the filaments or bristles in the recesses, and filaments or bristles held in the recesses by the insert. According to the invention, the base portion of the brush, and possible also the handle portion, is formed of a particular plastic which permits the insert which holds the filaments or bristles to press into the sides of the recesses with considerable pressure without cracking the sides so as to permit better holding of the filaments or bristles in the brush base. The plastic forming the base portion should be: a polyamide containing aliphatic, alicyclic and aromatic hydrocarbon units as basic components; a polyamide containing alicyclic and aromatic hydrocarbon units as basic components; a composition consisting of 30-0% by weight of polycarbonate and 70-10% by weight of polyethylene terephthalate; a composition containing 80-100% by weight of polybutylene terephthalate and 20-0% by weight of polyethylene terephthalate; or a composition consisting of 50-100% by weight of polyarylate and 50-0% by weight of polyethylene terephthalate.
