Synthesis and application of environmentally friendly modifier for heat transfer printing of cotton fabrics

The modifier for heat transfer printing of cotton fabrics was prepared by semi-continuous emulsion polymerization process.The relationship between monomer composition and color yield of printed products was investigated,and the effects of the different crosslinking monomers on properties of latex film,K/S value and color fastness of the printed products were analyzed.The results showed that the monomers of styrene(St) and acrylonitrile(AN) had great influence on the K/S value of the printed products.The satisfactory color yield and good brilliance of the printed products can be obtained when the dosage of St and AN was 30% and 5%,respectively.The polyethylene glycol(200) dimethyl acrylate was chosen as an ideal formaldehyde-free crosslinking monomer for transfer printing modifier,and when its dosage was 3%,the modifier of latex film showed lower dissolve-loss rate,higher breaking tenacity and elongation,and the modified cotton transfer printed with Disperse Red presented good color fastness.
