FIELD: production of complex chemical filaments.
SUBSTANCE: method involves producing by known method of filament with linear density of 0.05-0.17 tex by wet or dry-wet forming and winding onto winder with winding being combined with twisting operation; after forming and twisting processes, unwinding filaments from winder and joining into yarn with following stretching, finishing, drying and winding onto bobbin. Yarn may include from 5 to 30 filaments with linear density of 5-200 tex. Each of filaments from which yarn is composed is preliminarily stretched during forming procedure. Method allows complex chemical filaments with lower linear density to be produced.
EFFECT: stabilized process for manufacture of thin chemical filaments with reduced linear density and improved quality of filaments.
