FTIR Analysis for Studying the Possibility of Grafting onto Cotton of Some Compounds Resulted from the Interaction of Carbonyl Compounds with Monochlorotriazinyl-beta-Cyclodextrin

Abstract:

FTIR analysis is able to prove a grafting process, even when the grafting agencies are complicated. In this paper, the agents were obtained from a series of transformations of two carbonyl compounds (acetone and octanal) based on 2 stages: (1) activation of carbonyl compounds; (2) the combination of MCT-b-CD. Activation of acetone was performed with ethylene diamine and the activation of octanal was performed with HCl. Normally, without an activation step, acetone and octanal not react with MCT- b-CD because the group C=O ketone from acetone and respective group CH=O from octanal not react with the atom of Cl present on the triazine ring, that is the most reactive group from MCT-b-CD. Finally, the grafting agents obtained in the two situations were applied on cotton fabric by a pad-dry-cure technology. Grafting confirmation of each MCT-b-CD derivative produced by two methods qualitative: analysis FTIR and phenolphthalein test. In addition, the grafting has led to the improvement of non-wrinkle effects, effects valued by wrinkle recovery angles (WRA). Statistical analysis of WRA values indicated three conclusions: (1) the populations studied statistical are homogeneous; (2) the mean values of the WRA are representative of these populations; (3) the standard errors of the mean are very low. Keywords: FTIR, glyoxal, acetone, octanal, MCT-b-CD
