Abstract:

For a long time, discoloring PET/cotton blend fabric is a difficult topic in textile industry. For it, this search work was carried out to stripping PET/cotton fabric dyed by disperse/direct dye with dimethyl formamide. Though experiment, results is discovered as follows: firstly, the PET/cotton fabric dyed by disperse/direct dye is swelled in the home-made swelling liquid. Then, put it into striping liquid which is mainly contain dimethyl formamide, and heat to 140°C,and keep 30 minutes. The stripping rate of three kinds of test samples can be over 80 percent, and some can reach 95 percent. While the strength retention rate also can reach about 90 Percent.
