20.500.12556/DKUM-67824 Modification of polyamide knitted fabric using different zeolites Modificiranje poliamidnega pletiva z različnimi zeoliti The aim of this research was to apply three different types of zeolites and the combination thereof in the form of a very fine powder, together with different chemicals and additives on polyamide knitted fabric according to an industrially acceptable exhaustion procedure in order to study changes in the morphology, optical properties and wettability of surfaces. Zeolites were analysed using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and gas physiosorption. Additionally, the morphology of zeolite-coated surfaces was examined closely using SEM, while changes in molecular-chemical level were examined by means of IR spectroscopy. Optical properties were studied using CIE colour measurement and diff use reflectance profi le determination, while the hydrophilic/hydrophobic character was examined using goniometry. The obtained results show the suitability of the employed exhaustion procedure, depending on the type of zeolite and the composition of the treatment bath. The results also provided evidence of the enhanced wettability of PA fabrics using 4A and 13X zeolites in combination with selected additives. Namen predstavljene raziskave je bil nanesti tri različne tipe zeolitov in njihovo kombinacijo v obliki zelo finega prahu skupaj z različnimi kemikalijami in pomožnimi sredstvi na poliamidno pletivo po industrijsko sprejemljivem postopku izčrpavanja za študijo sprememb v morfologiji površine, optičnih lastnosti in omočljivosti. Zeolite smo analizirali s pomočjo vrstičnega elektronskega mikroskopa (SEM), Fourierjeve transformacijske infrardeče spektroskopije in plinske fizisorpcije. V nadaljevanju smo podrobno okarakterizirali z zeoliti oplaščene površine s pomočjo SEM, spremembe na molekularno-kemijski ravni s pomočjo IR-spektroskopije, optične lastnosti s pomočjo CIE-meritev in določanjem difuzijskega refleksijskega profila ter hidrofilni/hidrofobni značaj z goniometrijo. Dobljeni rezultati dokazujejo primernost uporabljenega postopka izčrpavanja v odvisnosti od vrste uporabljenega zeolita in se- stave obdelovalne kopeli. Prav tako rezultati dokazujejo povečano hidrofilnost PA pletenine pri uporabi zeolitov 4A in 13X v kombinaciji z izbranimi pomožnimi sredstvi. zeolites polyamide fibres exhaustion surface modification wettability zeoliti poliamidna vlakna izčrpavanje površinska modifikacija omočljivost true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-31 11:22:01 2017-08-31 11:24:25 2022-08-01 14:29:50 2019-07-11 16:32:36 2017 0 0 str. 116-125 št. 2 Letn. 60 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0351-3386 677.494.675.017 763396 20591894 10.14502/Tekstilec2017.60.116-125 0351-3386 URN:SI:UM:DK:FNX2ZQ7C TEKSTILEC_2017_Ojstrsek_et_al._Modification_of_Polyamide_Knitted_Fabric_using_Different_Zeolites.pdf TEKSTILEC_2017_Ojstrsek_et_al._Modification_of_Polyamide_Knitted_Fabric_using_Different_Zeolites.pdf 1 6C7F6D6AF2E642A0C2BBC848CC49E7FA 17736f7e0dd96c4b92850503b4d3c7f25bec6c8cf9cabb87914c826c28671b2c 99692477-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/d918aca6-4989-47db-b610-7464259b848d https://dk.um.si/Dokument.php?lang=slv&id=116575 http://www.tekstilec.si/wp-content/uploads/2017/06/116-125.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=116574 Fakulteta za strojništvo 0 0 0
