20.500.12556/DKUM-27730 Application of spectrophotometric methods in assessing the influence of alkaline treatment on the degree of crosslinking of cotton cellulose with BTCA Primjena spektrofotometrijskih metoda u procjeni utjecaja lužnatoga postupka na stupanj umrežavanja pamučne celuloze s 1,2,3,4-butantetrakarboksilnom kiselinom Polycarboxylic acids appear to be the most promising nonformaldehyde crosslinking agents to replace the traditional, mostly formaldehyde-based, compounds. The most effective among these acids is 1,2,3,4-butanetetracarboxylic acid (BTCA). In this study, a comparison was made of the crosslinking effect on mercerized and on unmercerized as well as with different BTCA mass fractions crosslinked cotton fibres using FT-IR spectroscopy, the methylene blue method and water retention determination. The main purpose of the research was to evaluate how the structural changes of mercerized cotton (transformation of cellulose I into cellulose II) influence the crosslinking of cellulose fibres. Većina do sada rabljenih spojeva za umrežavanje celuloze sadrži formaldehid. U novije se vrijeme takvi spojevi sve više zamjenjuju sa spojevima koji ne sadrže formaldehid. Od svih takvih spojeva najdjelotvornije su polikarboksilne kiseline, a među njima se najviše rabi 1,2,3,4-butantetrakarboksilna kiselina. Autori su proućavali utjecaj mercerizacije na umrežavanje celuloze, koja zbog promjene fine strukture povećava adsorpcijska svojstva celuloznih materijala. Cilj istraživanja bio je utvrditi spektrofotometrijskim metodama je li mercerizacija pomoću 1,2,3,4-butantetrakarboksilne kiseline utječe na umrežavanje celuloze. textile fibres cotton fibres cotton cellulose mercerization crosslinking tekstilna vlakna bombažna vlakna mercerizacija zamreženje bombažna celuloza true false true Angleški jezik Hrvaški jezik Znanstveno delo 2012-06-01 12:48:34 2012-06-01 12:48:34 2022-04-15 13:45:29 2021-04-11 03:27:43 2003 0 0 str. 293-298 št. 4 Letn. 76 2003 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0011-1643 677.016:677.047.6 22807 8469014 0011-1643 URN:SI:UM:DK:N9B3FNRG Croatica_Chemica_Acta_2003_Sauperl_et_al._Application_of_spectrophotometric_methods_in_assessing_the_influence_of_alkaline_treatment_on.pdf Croatica_Chemica_Acta_2003_Sauperl_et_al._Application_of_spectrophotometric_methods_in_assessing_the_influence_of_alkaline_treatment_on.pdf 1 76F624010E0ED27D9D20CFFA59164565 5815b86c038aeebe7eef86e2447f5b61e25c2a384bf2f76b6dc418b99c97afef 47f05544-7c07-11eb-bb7a-00155d0001ca 20.500.12556/dkum/47db592f-e7ce-4ee8-a1c4-54a22dac72f2 https://dk.um.si/Dokument.php?lang=slv&id=113644 http://hrcak.srce.hr/103190 1 https://dk.um.si/Dokument.php?lang=slv&id=37055 Fakulteta za strojništvo 0 0 0
