The invention discloses a dyeing method of textile. The dyeing method comprises steps as follows: the textile is put in a dye vat at a bath ratio of 1:4, the water temperature is increased to 45 DEG C, 4 g/L of dodecyl trimethyl ammonium sulfate, 18 g/L of aluminum sulfate and 7 g/L of polyoxyethylene stearates are added, the temperature is increased to 83 DEG C, heat preservation is performed for 45 min, and preliminary dyeing is finished; and textile after preliminary dyeing is put into a dye vat at a bath ratio of 2:3, 7 g/L of sodium ricinoleic acid n-butyl ester sulfate, 13 g/L of natural dye and 3 g/L of methyltrimethoxysilane are added when the water temperature is increased to 45 DEG C, PH is regulated to 3.7, the temperature is increased to 60 DEG C at the temperature increase speed of 5 DEG C/min, heat preservation is performed for 2 hours, and dyeing is finished. The dyed textile is environment-friendly, dyeing is uniform, and fading is prevented.
