Problems solved by technology

However, this alkaline dyeing solution contains impurities such as oligomers, dyes, dispersants, and shavings, which are very prone to uneven dyeing, and even dyes will coagulate.
However, some auxiliaries have poor heat and alkali resistance, are unstable in this alkaline dyeing environment, and are prone to denaturation.
The article "Research on Basic Dyeing and Leveling Agents for Polyester Superfine Fibers" (Advances in Textile Science and Technology, No. 2, 2013) also proposed a carrier-based alkaline leveling agent based on o-phenylphenol, but this leveling agent It will change the dyeing performance of polyester, decrease the color fastness to staining, and decrease the color fastness to rubbing

Abstract

The present invention belongs to the field of light chemical engineering, and particularly to a polyester fiber dyeing auxiliary agent. The present invention provides a special auxiliary agent for polyester disperse dye basic dyeing, wherein the special auxiliary agent can be adapted to basic dye bath and dying, can eliminate the reduction cleaning step, and even can be matched with the one-bath process of desizing, refining and dyeing, the final dyeing fabric has characteristics of good level dyeing property and soft hand feeling, and the color fastness reducing due to carrier dyeing is avoided.

Description

technical field [0001] The invention belongs to the field of light chemical engineering, and in particular relates to an auxiliary agent for dyeing polyester fibers. Background technique [0002] The dyeing process of polyester fiber with disperse dyes has always been in weak acidic medium, and the pH is generally controlled at 4.5-6, which is mainly considered from the stability of dyes and fibers. However, the pretreatment processes of polyester fabrics such as desizing, relaxation, alkali weight reduction, and polyester microfiber fabric opening are all carried out under alkaline conditions. Before dyeing, they must be fully washed and acid neutralized to remove the fabric. residual alkali. After the dyeing is completed, it is necessary to carry out post-treatments such as reduction cleaning and soaping in an alkaline medium. With the development of dyeing technology and technology, people are increasingly pursuing fast and energy-saving dyeing technology. Since the 198...
