Blocking agent for polyamide against direct dyes

Fixing agent to improve the wet fastness of polyamide

Dyeings of polyamide and blends of polyamide with cellulosic fibres on all devices and machines and in all types of making-up.

During dyeing of polyamide and cellulosic fibre blends PERFIXAN SFA conc. resists the polyamide against direct dyestuffs. With dyeings or prints of polyamide with acid dyestuffs, PERFIXAN SFA conc. is applied as aftertreating agent to improve the wet fastness. In case of modified polyamide fibres dyed with cationic dyestuffs PERFIXAN SFA conc. also improves the wet fastness.
