PURPOSE: A dyeing method of polyamide superfine fabric is characterized by adding magnesium chloride(MgCl2) to a dye bath in dyeing, improving adsorptive rate of dyes, giving excellent bathochromic effect and reducing a dye cost and a wastewater treatment cost. CONSTITUTION: A dyeing method of polyamide superfine fabric is as follows: dyeing the fabric with metal content acid dyes; and then putting 6-8wt.% of magnesium chloride(MgCl2) to a dye bath. The metal content acid dyes have sulfonic group(-SO3Na). The metal content acid dyes are non-sulfone type. |
