Abstract

M-aramid fibers have very good flame-retardant properties and are mostly used in protective textiles such as racing or firefighter suits. The dyeing and fastness properties of m-aramid fibers are investigated in this article in a batch process to optimize dyeing parameters such as dye concentration, salt, swelling agent, and temperature. The exhaustion at an acidic pH, preferably in the range of 4–5, indicated good results. The color yield of m-aramid fibers was found to be dependent on the concentration of swelling agent, salt, and dye, as well as the dyeing temperature. The effect of swelling agent on the K/S of m-aramid fibers with cationic dyes, along with their fastness properties, is investigated and reported in detail.
