Abstract

The invention discloses a dyeing auxiliary WPN for attenuated wool and common wool mixed tops as well as a dyeing method. The method for dyeing the attenuated wool and common wool mixed tops and the common wool mixed tops specifically comprises the following steps of: step 1. drawing the attenuated wool and common wool mixed tops and the common wool mixed tops to prepare the mixed wool tops; step 2. preparing a dyeing solution, adding the dyeing auxiliary WPN into the dyeing solution to form a dye-auxiliary mixed solution, and carrying out dyeing on the mixed wool tops by utilizing the dye-auxiliary mixed solution; and step 3. washing and drying the dyed mixed wool tops, so as to complete dyeing for the attenuated wool and common wool mixed tops. The dyeing auxiliary disclosed by the invention comprises nonionic surfactants of alkyl polyoxyethylene and aluminium salt, and is easy to prepare. With the adoption of the dyeing auxiliary and the dyeing method provided by the invention, the problem of whole collapse of the wool tops during the dyeing process is solved, the problem of aberration of inner and outer rings and irregular aberration are also solved, and the dyeing efficiency of the attenuated wools is improved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a dyeing auxiliary agent WPN for a fine wool-ordinary wool mixed top. The invention also relates to a method for dyeing a fine wool-ordinary wool mixed top by using the above-mentioned dyeing auxiliary WPN. Background technique [0002] After the ordinary wool is drawn, its dyeing performance also changes significantly. This is because the supermolecular structure of wool changes during the drawing process, and the wet modulus of the fiber decreases significantly. Under the humid and hot conditions of the dyeing process, wool Under the action of its own gravity, the hair ball will "collapse" as a whole, resulting in an increase in the fiber packing density and a decrease in the penetration ability of the dyeing solution to the fiber layer. At the same time, the "collapse" of wool tops can cause "empty space" between the top of the hair ball and th...
