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 wool dyeing method, in particular to a low-temperature rapid dyeing method for wool. Background technique [0002] In recent years, with the continuous development of dyeing technology, the traditional wool dyeing process is long, the temperature is high, and the shortcomings of the damage to the wool fiber are more and more unable to meet the needs of manufacturers. A low-temperature and rapid dyeing method is urgently sought. That is, at a lower temperature, the effect of traditional high-temperature dyeing can be achieved in a shorter period of time. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art and provide a new process for rapid dyeing of wool at low temperature. [0004] The technical solution of the present invention is realized in the following manner, including: the preparation of leveling agent, the preparation of dyeing solution and t...
