The invention relates to a method for
dyeing wool quickly at low temperature. The method comprises the following steps of: preparing a
levelling agent, preparing a dye solution and
dyeing the
wool at the low temperature, wherein 1) the
levelling agent is prepared from the following raw materials in part by weight: 15 to 25 parts of
sodium acetate, 25 to 35 parts of aromatic polyether
sodium benzene sulfonate, 5 to 15 parts of
sodium hydrogensulfite, 15 to 25 parts of n-
amyl alcohol and 1,000 parts of water, and a method for preparing the
levelling agent comprises the following steps of: weighing the
sodium acetate in the ratio, adding the
sodium acetate into the water, dissolving and stirring uniformly; and regulating the pH value to reach 4.5 by using glacial
acetic acid, adding the aromatic polyether sodium
benzene sulfonate, the sodium hydrogensulfite and the n-
amyl alcohol, and stirring the mixture in a constant temperature oscillator uniformly for 30 minutes for later use; and 2)the dye solution is prepared from the following raw materials in part by weight: 2 to 8 parts of dye, 1 to 5 parts of levelling agent and 1,000 parts of water, and a method for preparing the dye solution comprises the following steps of: adding the dye and the levelling agent into the water in the ratio, stirring uniformly, and regulating the pH value to be between 4.5 and 5 by using glacial
acetic acid for later use.
