Summary: | The invention relates to the field of textile dyeing and finishing, and particularly discloses a dyeing method of an elastic fabric. The dyeing method of the elastic fabric specifically comprises the following steps that S1, open-width desizing is conducted; S2, alkali decrement is conducted, wherein under the conditions that the bath ratio is 1: (40-50) and the temperature is 80-90 DEG C, a desized polyester gray fabric is subjected to heat preservation for 60-70 min in treating fluid, and the treating fluid comprises 0.5-1.0 g/L of a biquaternary ammonium salt cationic surface active agent, 12-20 mL/L of benzyl alcohol, 4-7 g/L of sodium hydroxide and 0.3-0.5 g/L of 4-heptylamine; S3, multi-stage water washing is performed; S4, dyeing is performed, wherein under the conditions that the water bath ratio is 1: (15-20) and the pH value is 4-5, dyeing treatment is performed on the polyester gray fabric subjected to multi-stage water washing in dye liquor; S5, continuous open-width cleaning is performed; S6, set |
