I have dyed jute-cotton blended fiber with onion peel and other tannin-containing mordants. But after FTIR analysis, we could not explain if there was an increase in bond formation due to the use of tannin than the non mordanted.Now is there a better spectroscopic method for better understanding bond formation in dyed sample and are there ways to determine the amount of bond formation in a particular sample?
