FIELD: polymer materials. n SUBSTANCE: invention relates to technology of fabricating polyolefin fibers used for woven and nonwoven materials, in particular to imparting wettability to the latter, and can be used in manufacture of hygienic appliances, filters, accumulator battery separators, and the like. Elementary threads and two-component fibers are made from molten mixture of polyolefin and at least one compound of formula: R 1 -hydrophilic oligomer, wherein R 1 denotes straight-chain or branched C 22 -C 40 -alkyl and hydrophilic oligomer is homo- or cooligomer comprising 2-10 monomer units derived from monomers selected from group including ethylene oxide, propylene oxide, ethylene glycol, propylene glycol, epichlorohydrin, acrylic acid, methacrylic acid, ethyleneimine, caprolactone, vinyl alcohol, and vinyl acetate. n EFFECT: achieved excellent prolonged wettability of fibers and textiles. n 15 cl, 4 ex |
