Abstract RU 2357982 C2

FIELD: chemistry.

SUBSTANCE: present invention refers to fibre dull polish ensured by mixed mineral additives in raised polymer thermoplastic compositions. Associated mineral additives contain at least two mineral additives chosen from the group containing zinc sulphide, titanium dioxide, barium sulphate, silicon dioxide, alumina, kaolin, calcium carbonate, calcium sulphate, mat clay. The polymer composition for product spinning as filaments, fibres, filament fibres contains associated mineral additives 2 wt % to 4 wt %.

EFFECT: high dulling factor of thermoplastic polymers.
