Cyclodextrins in Textile Finishing: Fixation and Analysis
Following a short overview of application of cyclodextrins (CDs) in textile finishing methods for the permanent fixation of CDs onto texiles and approaches to their quantitative analysis are reviewed. A new analytical method, based on the inclusion complexation of ferrocene, and a quantitative study, utilizing this method, on the covalent fixation, washing fastness and formaldehyde release of CD-containing finishes are presented. Ferrocene complexation is proven by Raman spectroscopy and by comparison with maltodextrin. Some of the finishing treatments resulted high yields and permanence against washing. Hydroxypropyl-CD reduced formaldehyde release and acted possibly as a formaldehyde scavenger. Using “low formaldehyde” crosslinkers ” requirements easily met.
