Abstract

The invention discloses a method for dyeing a wool-like fabric, and the method comprises the following steps: 1) adding borax, dimethylamine, sodium pyrophosphate, ethylene glycol phenyl ether and a plant dye in turn into deionized water in a dyeing vat, stirring well, and heating to 45 DEG C; 2) in turn adding n-butyl acrylate, secondary alkyl sodium sulfonate, diphenyl ether tetracarboxylic acid dianhydride and methacryloxyethyltrimethyl ammonium chloride, continuing to stir until even mixing, and heating at 60 DEG C; 3) soaking the fabric for 45 minutes in the dyeing vat; 4) drying the soaked fabric at 85 DEG C; 5) dipping the dried fabric into clean water for rinsing for 45 minutes; and 6) taking the rinsed fabric for drying in air naturally. The dyed fabric has excellent color fastness and good dyeing uniformity, and is free of dyeing defects.

Description
