The resin fixing agent of condensation of dicyandiamide and formaldehyde has been used for a long time, but since the last century, it has been found that the fixing agent contains very high free formaldehyde in children's underwear after finishing, which leads to the skin fixing. Inflammation and even ulcers have attracted people's attention to begin the study of aldehyde-free fixing agents. At present, many countries have strict restrictions on the mass fraction of formaldehyde in textiles.
