The research on the Properties of Blue Vat Dyes Series for Fatigue Clothes

Conventional blue vat dyes series (Blue BO,Blue BC,Blue RSN,Blue VB) for fatigue clothes were lack of fastness to chlorine bleaching. Several new blue vat dyes series for fatigue clothes (Blue NBS,Blue RCS,Deep Blue DB,Blue YBB) were introduced. Their fastness performances were compared by experiments and several high fastness blue vat dyes series for fatigue clothes were recommended.
