Abstract

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.

Secondary title:	Primjena spektrofotometrijskih metoda u procjeni utjecaja lužnatoga postupka na stupanj umrežavanja pamučne celuloze s 1,2,3,4-butantetrakarboksilnom kiselinom
Secondary abstract:	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.
