The invention provides an inorganic pigment dyeing method for cotton textiles. First, the cotton textiles are placed in a washing solution for washing and drying pretreatment; then, a silane coupling agent is added to the organic solvent dispersion of inorganic pigment nanoparticles for modification reaction to obtain modified inorganic pigment nanoparticles; then, The initiator ammonium persulfate is added to the modifier solution, and then the modified inorganic pigment nanoparticles and the pretreated cotton textile are added for coloring treatment to obtain a pre-dyed cotton textile; finally, the pre-dyed cotton textile is put into The dyeing treatment is carried out in a high boiling point solvent, and then washed and dried to obtain a cotton textile dyed with inorganic pigments. In the dyeing method provided by the invention, under the condition of high temperature, normal pressure and high boiling point solvent bath dyeing, the cotton fibers modified by inorganic pigments are dyed, so as to realize fast and efficient dyeing of cotton fabrics with inorganic pigments and high color fastness. dye utilization. |
