Problems solved by technology

But because disperse yellow RGFL (C.I. disperse yellow 23) is included in the banned disperse dyes by German government Oeko-Tex Standard 100 and European Union Eco-Label, so all countries in the world research and develop its substitute vigorously, disclosed in the patent CN1125240 The dyeing performance of the dye is good, but the shade of the dyed fabric is not bright enough

Embodiment 1

[0027] Component A of 34 grams of formula (I-1), component B of 66 grams of formula (II-1), sodium lignosulfonate of 160 grams, after adding 600 grams of water and blending, grind and disperse with a grinder, spray After drying, the finished product is obtained. The dye can provide uniform bright yellow color to the fabric with good fastness properties.

Abstract

This invention provides disperse yellow dye composition, which comprises component A (one or more compound as shown in chemical formula I) 5-40 wt.% and component B (one or more compound as shown in chemical formula II) 60-95 wt.%. Polyester fiber material dyed with the dye prepared from the disperse yellow dye composition is a yellow fabric, and has such advantages of fresh color, high dispersibility, high washing resistance and high sweat resistance.

Description

(1) Technical field [0001] The invention relates to a disperse yellow dye composition, in particular to a disperse yellow dye composition for printing and dyeing polyester and its blended fabrics. (2) Background technology [0002] With the rapid development of new polyester fibers in recent years and the improvement of people's requirements for textiles, correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself. Not only the dyestuffs are required to have high lifting power and various dyeing fastnesses, but also the dyestuffs are required to have good environmental performance to avoid pollution to the environment. [0003] As far as disperse dyes are concerned, the large-scale development of new dye structures is rare, and a lot of work has turned to the research on the application performance of dyes, the synergy between dyes and the compounding and synergy of dyes and auxiliaries.
