Problems solved by technology

At present, there is a great demand for disperse orange with reddish light in the market. The traditional disperse orange 76# has been widely used in this area, but because it is listed as an allergenic and non-environmental friendly dye, it is necessary to look for an environmentally friendly, level dyeing Good, the fastness is good, the cost is low, and the disperse orange composite dye that can replace 76# orange is urgent

Embodiment 1－6

[0033] According to the components and contents shown in Table 1, the prepared composite dye composition, auxiliary agent and water were mixed, ground, and spray-dried to obtain a composite disperse dye.

[0034] Table 1

[0035]

[0036] Use 0.1 g of the composite disperse dyes prepared in Examples 1-6, together with 10 g of polyester fabric and water, adjust the pH of the dyeing bath to 5~5.5 with acetic acid, heat up to 130 ° C within 35 minutes, and keep the temperature for 30 Minutes, cooled to 80°C and sampled to obtain a yellow to orange textile material. According to the standards of GB / T2397-2003 and GB / T2043-2006, the lifting force and pH adaptation were tested, and the results are shown in Table 2.

Abstract

The invention relates to a complex dye composition, complex disperse dyes and preparation methods of the composition and the dyes. The complex dye composition comprises the following constituents shown in the following formulas (I), (II) and (III). According to the invention, the complex disperse dyes are environmental-friendly disperse yellow to orange dyes which are good in lifting power, good in washing fastness, and wide PH applicable range, and good in compatibility.

Description

technical field [0001] The present invention relates to a kind of composite dye composition, composite disperse dye and preparation method thereof, the present invention also relates to composite dye composition and composite disperse dye for the purposes of dyeing and / or printing of textile, with described composite dye composition Textiles obtained by dyeing and / or printing with complex disperse dyes and textile products made from the textiles. The disperse dye is more suitable for reddish orange dyeing and printing of polyester and its blended fabrics. Background technique [0002] With the rapid development of polyester and its blended fabrics, people have higher and higher requirements for the application performance of dyes, such as dye leveling and fastness, etc. are all required by customers. At present, there is a great demand for disperse orange with reddish light in the market. The traditional disperse orange 76# has been widely used in this area, but because it ...
