20.500.12556/DKUM-67850 Statistično načrtovanje postopka apretiranja viskoznih tkanin iz močno vite preje. 2.del: Apretiranje z neformaldehidnimi reagenti Statistical desgning of finishing process for viscose fabrics made from hard twisted yarn. Part 1: Finishing with non-fomaldehyde reagents Prispevek obravnava rezultate optimiranja zamreženja tkanin iz močno vite viskozne preje z brezformaldehidnim reagentom. Proučevali smo vpliv koncentracije brezformaldehidnega reagenta za zamreženje, katalizatorja in neionogenega sredstva za mehčanje na nekatere uporabne lastnosti apretirane viskozne preje. Spremljali smo naslednje veličine: stopnjo nabrekanja viskoznih vlaken, barve razlike, pretržno silo, pretržni raztezek in kot razgubanja. Z uporabo brezformaldehidnega reagenta za zamreženje smo dosegli znižanje stopnje nabrekanja viskoznih vlaken za 51,1 do 92,4 %, povečanje kota razgubanja za 60 do 145%, zmanjšanje pretržne sile za 49% do 65% in pretržnega raztezka za 31,6 do 37,6%. Postopek zamreženja ne povzroča zaznavnik barvnih razlik in obarvanih tkanin. The paper presents the results of optimizing cross-linking of fabrics made from highly twisted viscose yarn by using the nonformaldehyde reagents. The influence of the crosslinking reagent concentration, catalyst and nonionogenic softener on some applicability properties of the finished viscose fabric was investigated. The following parameters were monitored: the degree of swelling of viscose fibres, elongation at break and crease recovery angle, as well as the influence of the finishing process on the colour of viscose fabrics made from highly twisted yarn. By using the cross-linking non-formaldehyde reagent the degree of swelling of viscose fibres decreased by 51.1 - 92.4%, the crease recovery angle increased by 65 - 145%, the breaking force decreased by 49 - 65%, and the elongation at break decreased by 31.6 - 37.6 %. The crosslinking process did not cause any noticeable colour deviations on the dyed fabric. celulozna vlakna vrhunsko plemenitenje brezformaldehidno zamreženje matematično-statistične metode načrtovanja poskusov kot razgubanja mehanske lastnosti barvna metrika nabrekljivost viskoznih vlaken cellulose fibers high-grade finishing cross-linking with non-formaldehyde reagent mathematical-statistical methods of experiment designing angle of decrease mechanical properties colorimetry swelling capacity of viscose fibers true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-08-31 14:59:28 2017-08-31 15:00:46 2022-08-01 14:31:41 2019-07-11 16:33:14 2004 0 0 str. 292-300 št. 9/12 Letn. 47 sep.-dec. 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0351-3386 677.027.6:677.463 763396 9362966 0351-3386 URN:SI:UM:DK:EMJW4YJT Tekstilec_2004_Iskrac_et_al._Statisticno_nacrtovanje_postopka_apretiranja_viskoznih_tkanin_iz_mocno_vite_preje._Del_2,_Apretiranje_z_nef.pdf Tekstilec_2004_Iskrac_et_al._Statisticno_nacrtovanje_postopka_apretiranja_viskoznih_tkanin_iz_mocno_vite_preje._Del_2,_Apretiranje_z_nef.pdf 1 A5AB4B26E1015367A5693DDC5746DF3C bc73a74d7ec65c19bf6052c00afc1b9fd2148ac35c9e3bca4c208be5e2bad772 9b4946dc-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e654d227-5949-4ca4-a839-b6379a0124d0 https://dk.um.si/Dokument.php?lang=slv&id=116646 http://www.tekstilec.si/wp-content/uploads/2004/09/Statistical-Designing-of-Finishing-Process-for-Viscose-Fabrics-Made-from-Hard-Twisted-Yarn-%E2%80%93-Part.-2-Finishing-with-the-Non-Formaldehyde-Reagents.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=116645 Fakulteta za strojništvo 0 0 0
