Comparison of the resist effectiveness and leveling character of α-bromoacrylamide based and 2,4-dichloro-s-triazine based dye-resist agents for wool

Three dye-resists based on α-bromoacrylamide and three dye-resists based on dichlorotriazine were synthesized and their effectiveness and leveling properties were compared on wool. In general, the dichlorotriazine based dye-resist agents displayed higher resist effectiveness than their α-bromoacrylamide counterparts. However, the dye-resists based on α-bromoacrylamide exhibited better leveling properties than those based on dichlorotriazine. The resist effectiveness was significantly improved by increasing the number of sulphonate group in the dye-resist agents and the hydrophilic character of anionic dyes applied over them.
