Sažetak
Stabilisation of cellulose material dimensions and shape has always been the field of concern for consumers. Finding competitively priced non-formaldehyde Durable Press (DP) finishes has become one among the highest priorities for textile finishing industry. From the ecological point of view, polycarboxylic acids (PCA) are highly justified, while economical problem of high price is solved in various ways. Maximum effects of DP finishing among PCA are obtained with 1,2,3,4-butanetetracarboxylic acid (BTCA), exceedingly high costs of which are well known. Because of the widespread availability and low costs, citric acid (CA) has become quite interesting for the DP finishing treatment. The greatest disadvantage of CA is its tendency to impart noticeable fabric yellowing under elevated cure conditions. Yellowing of the textile material is probably due to the formation of unsaturated polycarboxylic acids. Instead of the usual curing process performed at very high temperatures, we have used electromagnetic (EM) waves from high frequency drier. This procedure yielded much better results regarding fabric resilience, while whiteness degree has not been significantly lowered. The influence of EM waves on the efficiency of esterification has been studied by FT-IR spectroscopy method. By measuring ester carbonyl band intensity of textile materials cured in two different ways, the amount of ester is determined. Although this treatment has been tested under laboratory conditions as far, the first results are quite promising regarding future application in the field.
