The oil was added to the polymer in the feeding zone of the extruder prior melting of the polymer. The PP filament yarns and the filament yarns to which the oil was added were spun at three different temperatures. The objective of the study was to investigate the influence of the addition of paraffin oil on the spinning process and on the properties of produced filament yarnsV pričujoči raziskavi je bilo kot dodatek pri izdelavi PP vlaken na laboratorijski predilno-raztezalni napravi, uporabljeno parafinsko olje v 10% masnem deležu. Parafinsko olje je bilo dodano pred vstopom polimera v polnilno cono ekstruderja. PP vlakna, izdelana z in brez dodatka olja, so bila oblikovana pri treh različnih temperaturah. Namen raziskave je bil raziskati vpliv dodatka parafinskega olja na predilni proces ter na tekstilne in mehanske lastnosti izdelanih PP vlakenNadaljuje se kot: Materiali in tehnologijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
