Cotton is subjected to one-bath dyeing and durable press finishing (ODF) with dialde hyde and a monochlorotriazinyl reactive dye. Results indicate that an optimal curing temperature is 150°C to simultaneously fix dialdehyde 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 ODF process with dialdehyde and reactive dye.
