Sažetak
Main disadvantage of classical DP finishing agents ( N-methylol based products ) is their formaldehyde release. Recently more attention has been paid to polycarboxylic acids (PCA) and the possibility of their application. The best results have been obtained with butanetetracarboxylic acid (BTCA) and citric acid (CA). Although BTCA is highly effective in the presence of certain weak base catalysts at elevated curing temperatures, it is currently too expensive for large scale textile applications. On the other hand a citric acid, in spite of its low cost, widespread availability and ecological acceptability has negative tendency to impart noticeable fabric yellowing under the usual cure conditions. To prevent the fabric yellowing we have investigated the impact of electron acceptor aluminum chloride which served as co-catalyst together with sodium hypophpsphite. Main catalyst for the esterification process is still sodium hypophosphite and its usually high concentrations we tried to reduce. The chemical finishing costs would be lowered greatly if an inexpensive acid such as citric or maleic acid could be used with lower concentrations of BTCA to give a mixed finishing agent of the required effectiveness. This research sought to improve the appearance properties of CA treated fabrics mixing it with BTCA and to eliminate or minimze
