FIELD: soft wares, paper.
SUBSTANCE: invention concerns high-grade polyethylene multifiber yarn technology. Method includes stages of receiving ultrahigh-molecular-weight polyethylene solution in solvent; forming from solution through draw die with variety of holes into air gap with filament formation in liquid condition at stretching grade DRl; cooling of filament in liquid condition with formation jellous filament, which contains solvent; , at least, partly from filament; and filament stretching, at least, at one stage before, during and/or after mentioned , at stretching grade DRsolid, where DRl=DRhole × DRag, at least, 50, DRhole - stretching grade in holes, DRag - stretching grade in air gap; DRhole is more than 1, and DRag is equal, at least, 1. Furthermore, invention concerns draw die with holes of concrete shape.
EFFECT: receiving of high-grade multifiber yarn with uniform and high-strength characteristics.
