Cotton is subjected to one-bath dyeing and durable press finishing (ODP) with aldehyde and a monochlorotriazine reactive dye . Results indicate that an optimal curing temperature is 150*C to simultaneously fix aldehyde and reactive dye on cotton Changing the immersion temperature and time ( 40*C for 20 minutes ) in the treatment bath greatly enhances the efficiency of the OF process with aldehyde and reactive dye .
