FIELD: polymer materials. ^ SUBSTANCE: invention relates to technology of manufacturing thermoplastic monofilaments and can be used in fabrication of bristle used under high humidity conditions. Monofilament is composed of polymer blend constituted by at least one polyamide and at least one thermoplastic polyester. Ratio of constituents in the blend is selected according to technical and functional properties determined, on one hand, by destination of bristle and, on the other hand, by environmental conditions in the bristle application location. Polyamide fraction ranges from 10 to 30% and that of polyester from 70 to 90%. Bristle completely meets functional and technical requirements as well as environmental conditions. ^ EFFECT: reduced manufacturing cost. ^ 16 cl |
