Formaldehyde-free non-irons finishing process of Lyocell fabric with citric acid-polyurethane
G100 Lyocell fabric,which was easy to fibrinate,was chosen as the research object.The crease resistance and wear performance of Lyocell fabric were improved by the collaborative application of cit-ric acid and polyurethane.The research determined the processing technology of citric acid-polyurethane non-irons finish:the amount of citric acid was 120 g/L,the amount of polyurethane was 20 g/L,the formaldehyde content of the citric acid-polyurethane non-irons finish fabric was ND(not detected),and the flatness of the fabric after 5 times of washing was 3.2 level.In addition,infrared spectra,thermogravimetric and X-ray diffrac-tion techniques were used to characterize the changes of fiber properties before and after finishing.
