ABSTRACT:
Methods for lowering the free formaldehyde release in carbamate durable press treatment solution and finished fabric are disclosed. Concentrated carbamate finishing agent solution of lowered free formaldehyde content comprises oxidizing a carbamate finishing agent solution containing free formaldehyde with a sufficient amount of magnesium monoperoxyphthalate oxidant to decrease the free formaldehyde content of the solution. Sufficient amount of catalyst is added to this solution to produce press properties in cellulose containing fabric to make a treatment bath. Cellulose containing fabric is immersed in this bath for sufficient time and temperature to produce lowered free formaldehyde release carbamate durable press finished fabric. High free formaldehyde carbamate-finished durable press cellulose containing fabric can be treated with a solution of magnesium monoperoxyphthalate oxidant of sufficient concentration for sufficient time and temperature to oxidize the free formaldehyde and thereby produce a lowered free formaldehyde release carbamate durable press finished fabric.
