FIELD: chemistry.
SUBSTANCE: invention relates to glass filaments coated with a lubricating composition containing (wt %): 25-90% of at least one film-forming agent, 3-25% of at least one binder, 2-18 nanoparticles. The lubricating composition contains the following in wt %: film-forming agent 1.5-15, binder 0.15-4, clay or boehmite nanoparticles 0.1-4, lubricating material 0.1-1.2, dispersant 0.05-2, viscosity regulator 0.05-2.
EFFECT: high wear resistance of the glass filaments coated with a lubricating agent, high ageing resistance in a moist environment.
