Abstract:

Cyclodextrins (CDs) can form molecular complexes with a very wide range of compounds thanks to their hydrophobic internal cavity. This feature enables them to be incorporated into fabrics, to entrap and mask a very wide range of solid, liquid and gaseous odours. One well-known disadvantage of classical crease-resistant finish is that the treated fabrics emit formaldehyde, and there are several approaches to preventing or decreasing the volume of formaldehyde emitted. In this study we evaluate the possibility of using CDs for this purpose. We assumed that formaldehyde would settle within the cavity of the CD, and that the cross-linking occurring between CDs and the cross-linking agent would the increase the crease-resistance property. However, the presence of CDs in crease-resistant finish did not show the expected results.
