Abstract

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.

Description

Technical field [0001] The invention relates to a method for dyeing wool, in particular to a method for fast dyeing wool at low temperature. Background technique [0002] In recent years, with the continuous development of dyeing technology, the traditional wool dyeing process has the disadvantages of long process flow, high temperature, and large damage to wool fibers. It has become increasingly unable to meet the needs of manufacturers. It is urgent to seek a low-temperature and rapid dyeing method. That is, the effect of traditional high-temperature dyeing can be achieved in a relatively short time at a lower temperature. Summary of the invention [0003] The technical task of the present invention is to solve the shortcomings of the prior art and provide a new process for fast dyeing of wool at low temperature. [0004] The technical scheme of the present invention is realized in the following ways, including: preparation of levelling agent, preparation of dye liquor and low-te...
