Abstract

The invention provides a disperse black dye composition, a disperse black dye as well as a preparation method and an application of the disperse black dye. The disperse black dye composition comprisesa component A, a component B and a component C in a mass ratio of (2-5):(1-3):(2-4); and the component A comprises one or more compounds represented as a formula I and / or a formula I', the componentB comprises one or more compounds represented as a formula II, and the component C comprises one or more compounds represented as a formula III. The disperse black dye comprises the disperse black dyecomposition. The preparation method of the disperse black dye comprises the steps as follows: after being mixed uniformly, the raw materials are ground and dried, and the disperse black dye is obtained. According to the application of the disperse black dye, the disperse black dye is applied to dyeing of polyester fibers and blended fabric of the polyester fibers. The disperse black dye composition and the disperse black dye have good alkali resistance and a wide dye bath pH range, pretreatment and dyeing can be performed in a synchronous one-bath manner, the technological process is shortened, and effects of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to the field of dyeing and finishing, in particular to a disperse black dye composition, a disperse black dye and a preparation method and application thereof. Background technique [0002] In recent years, with the rapid development of the polyester fiber industry, the continuous improvement of the dyeing process, and the innovation of various dye auxiliaries, people's requirements for textiles and environmental protection have also been continuously improved, with the advantages of clean production, pollution reduction, energy saving and consumption reduction. New disperse dyes are increasingly favored by textile dyeing and finishing enterprises. [0003] Usually, in the dyeing and finishing of polyester and its blended fabrics, most disperse dyes are dyed in acid baths, while pretreatment desizing, scouring and alkali reduction processes, and reduction cleaning after dyeing are carried out under alkaline conditions. The dyeing...
