Application of spectrophotometric methods in assessing the influence of alkaline treatment on the degree of crosslinking of cotton cellulose with BTCAŠauperl, Olivera (Avtor) Stana-Kleinschek, Karin (Avtor) Vončina, Bojana (Avtor) Sfiligoj-Smole, Majda (Avtor) Majcen Le Marechal, Alenka (Avtor) textile fibrescotton fibrescotton cellulosemercerizationcrosslinkingPolycarboxylic 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.20032012-06-01 12:48:34Znanstveno delo27730ISSN: 0011-1643UDK: 677.016:677.047.6OceCobissID: 22807COBISS_ID: 8469014ISSN pri članku: 0011-1643NUK URN: URN:SI:UM:DK:N9B3FNRGsl
