Abstract

Since with most croslinking agents harmful formaldehyde is released, they are substituted with so-called non-formaldehyde reagents. Various polycarboxylic acids were applied. The most effective among these is 1,2,3,4 butanetetracarboxylic acid (BTCA). In this study, a comparison of accesible carboxyl groups amount into mercerized as much as unmercerized and with different mass fractions of BTCA crosslinked cotton fibres was made using Methylene blue method and the complexometric titration. The purpose of this research was mainly to evaluate how the structural changes of mercerized cotton cellulose influence the accesible carboxyl groups amount of the cellulose fibres crosslinked with different BTCA mass fractions in the impregnation bath. The accesible carboxyl groups quantity reflects the effectiveness of cotton cellulose crosslinking with BTCA.
