Process for producing selective caustic crepe using reactive dyes

摘要

Causticisation-based local crimp (curl) effects together with identical colour patterns in the piece can be obtained by using reactive dyes in the crepe resist (reserve) which constitutes a combination of mixtures of reactive polysiloxanes with self-crosslinking copolymer dispersions based on acrylate or butadiene. And the effectiveness of such a specific coloured crepe resist, applied as first print (preprint), is at the same time successfully utilised as a mechanical dye resist for subsequent overlappingly applied ground pastes (colours) composed of reactive dyes. By further addition of chemical resisting agents to the crepe resist the attainable colour effects are made still more varied in the cross-dyeing (over-dyeing).
