20.500.12556/DKUM-53122 Microvoid system in fibres Sistem praznin v vlaknih The macrovoid system of poly(ethylene terephthalate) (PET) and poly(propylene) (PP) fibres was studied by small-angle x-ray scattering (SAXS). Commercial PET textile fibres were treated in different media and the influence on fibre homogeneity was followd by SAXS. PP technical fibres were manufactured on a laboratory spin-drawing device and subsequently drawn at different drawing conditions on a laboratory drawing device. The influence of drawing on the pore system was followed. V prispevku smo z ozkokotnim rentgenskim sipanjem (SAXS) proučili sistem mikrovotlin v polietilentereftalatnih (PET) in polipropilenskih (PP) vlaknih. Komercialna PET tekstilna vlakna smo obdelali v različnih medijih in spremljali vpliv pogojev obdelave na homogenost vlaken s SAXS. Konvencionalno barvanje vlaken v vodnem mediju in in toplotna obdelava vlaken v vročem zraku povzročita spremembe v sistemu por vlakna. Na laboratorijski predilno-raztezalni napravi smo izdelali tehnična PP vlakna ter določili vpliv raztezanja na sistem por v vlaknu. Raztezanje vpliva na oblikovanje sistema praznin v vlaknu. textile industry textile fibres morphology structure investigations SAXS poly(ethylene terephtalate) PET poly(propylene) PP voids microvoids tekstilstvo tekstilna vlakna morfologija struktura preiskave SAXS polietielen tereftalat PET polipropilen PP praznine mikrovotline true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-07-10 19:23:48 2015-07-10 19:23:48 2022-06-02 03:09:05 2021-05-10 03:34:13 2002 0 0 str. 773-782 4 49 dec. 2002 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 677.4.017 14086149 7604758 1318-0207 URN:SI:UM:DK:5KD5UPRK Acta_Chimica_Slovenica_2002_Smole,_Gregor-Svetec_Microvoid_system_in_fibres.pdf Acta_Chimica_Slovenica_2002_Smole,_Gregor-Svetec_Microvoid_system_in_fibres.pdf 1 21B87FC8492C75AFB1D2A8111960CBFB 42ff711166cb8f2f53801493e5ae623a93f7cff47ceb13856b31a3c0259346c6 8afb9065-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=115751 http://acta-arhiv.chem-soc.si/49/49-4-773.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=77682 Fakulteta za strojništvo 0 0 0
