Application and Practice of Rubbing Fastness Improver DM-2589N

The purpose of this paper is to introduce the application and Practice of a wet rubbing fastness improver DM-2589N in dark cotton fabrics. Methodology - The influence of DM-2589N mass concentration, baking temperature and time on the rubbing fastness are studied. The effects of DM-2589N on different fabrics, different dyes, and the effects of DM-2589N and other finishing agents in the same bath are studied. Findings - DM-2589N has excellent lifting effect on all kinds of cotton fabrics, and it is suitable for the improvement of rubbing fastness of fabrics dyed with reactive, direct, vulcanized and vat dyes. the optimum process is DM-2589N 40g/L, One dip and one rolling, baking temperature 150°C. Practical implications - The dry and wet rubbing fastness of the finish products can be increased above Grade 3-4, which can meet the first-class quality requirements of customers. Originality/value – The wet-rubbing fastness improver DM-2589N can be used in the same bath with the fixing agent and softener without adjusting the pH value, which can simplify the production process, shorten production time and greatly improve production efficiency
