FIELD: textile industry.
SUBSTANCE: invention relates to textile industry and can be used for production of modified fabric. Method of applying nanoparticles of hexagonal boron nitride (h-BN) on the surface of filaments of polyamide fibres involves ultrasonic treatment of filaments of polyamide fibres in a mixture of distilled water with nanoparticles of h-BN and preparing a lubricant with mineral additives. Ultrasonic treatment is performed for at least 2 and not more than 9 minutes. Solution of h-BN nanoparticles is preliminarily prepared in distilled water using ultrasonic treatment for 60 minutes, at which layering of the h-BN nanoparticles is achieved.
EFFECT: invention improves the attachment of hexagonal boron nitride nanoparticles to the surface of filaments of synthetic fibres.
