Cyclodextrins are cyclic oligosaccharides, which form complexes with different organic substances such as drugs, odors, and etc. Due to the complexing abilities of cyclodextrins (CDs), they may also be used in textile industry as an auxiliary in washing, dyeing, and wastewater treatment. Fixation of CDs on textiles is possible using reactive derivatives of cyclodextrins or crosslinking agents. In this study we have investigated the use of polyaminocarboxylic acids (PACAs) as novel crosslinking agents for the fixation of beta-CD on cotton fabrics. Fixation of beta-CD on cotton fabric has been quantified by measuring the weight increase of the treated samples. The influence of the concentration of the catalyst (sodium hypophosphite) was studied, too. The presence of beta-CD on the cotton has been investigated by the phenolphthalein test and host-guest complexation with organic volatile molecules: cyclohexene, chlorobenzene, cyclohexene-1-one and toluene.
