High-fastness turquoise blue disperse dye composition

Abstract

The invention provides an environment-friendly and economical high-fastness turquoise blue disperse dye composition with bright colored light, good leveling property, good elevating power and excellent washing fastness and sublimation fastness. The high-fastness turquoise blue disperse dye composition mainly comprises the following components in parts by weight: 50-90 parts of a component A shown by a formula (I), 0.1-10 parts of a component B shown by a formula (II) and 0.1-45 parts of a component C shown by a formula (III). After being commercialized, the turquoise blue disperse dye composition provided by the invention can be ground to be in a liquid state by a sand mill or a grinder, and can be in the shape of powder or particle after being subjected to spray drying, so that the turquoise blue disperse dye composition is suitable for dyeing of polyester and a blended fabric thereof, and particularly suitable for dyeing of a spandex blended fabric, and has the characteristics of good elevating power, small contamination to spandex, excellent washing fastness, excellent color fastness to sublimation and the like.

Description

(1) Technical field [0001] The invention relates to a disperse dye composition, in particular to a high-fastness disperse turquoise blue dye composition suitable for dyeing polyester fibers and their blended fabrics. (2) Background technology [0002] With the accelerated development of the times and the continuous improvement of people's living standards, different types of new textile fabrics have emerged. Swimwear and related casual clothing. Although polyester and ammonia fabrics can also be dyed with conventional disperse dyes, such as C.I. disperse blue 60, which is widely used because of its bright color and high light fastness, but the dye has low color strength, high price, washing fastness, sublimation fastness, etc. The indicators are difficult to meet the requirements of mid-to-high-end sportswear fabric enterprises. Considering the limitations and development costs of monochromatic dyes when dyeing dark colors, industry technicians are increasingly trying to im...

AI Technical Summary

Problems solved by technology

Polyester-spandex fabrics can also be dyed with conventional disperse dyes, such as C.I. Disperse Blue 60, which is widely used because of its bright color and high light fastness, but the dye has low color strength and high price, and its washing fastness and sublimation fastness, etc. The indicators are difficult to meet the requirements of middle and high-end sportswear fabric enterprises. Considering the limitations and development costs of single-color dyes in dyeing dark colors, industry technicians are increasingly trying to improve the dyeing of dyes through compounding and synergistic technologies. performance
