[0058] According to the data in Table 1, the mixture of component A, component B, component C, component D, component E, component F, additives and water was ground and dispersed with a sand mill, and then spray-dried. Component A, component B, component C, component D, component E and component F can be prepared by using disperse dyes produced by Zhejiang Runtu Co., Ltd. or by existing methods.

[0059] The preparation method of structural formula (1-1) is: after diazotization of 2,4-dinitro-6-bromoaniline, and then with 2-methoxy-5-acetylamino-N,N-dimethoxycarbonyl Formed by coupling methylaniline;

[0060] The preparation method of structural formula (1-2) is: after diazotization of 2,4-dinitro-6-chloroaniline, and then with 2-methoxy-5-acetylamino-N,N-dimethoxycarbonyl Formed by coupling methylaniline;

[0061] The preparation method of structural formula (1-3) is: after diazotization of 2,4-dinitro-6-cyanoaniline, and then with 2-ethoxy-5-acetylamino-N,N-dimethoxycarbon ...

Abstract

The invention discloses a disperse dye composition for polyester / spandex fiber dyeing and printing, which mainly comprises the following components in percentage by weight: 36%-78.5% of component A, 4.5%-20% of component B, 10%-36% of component C, 6%-28% of component D, 0.5%-3% of component E and 0.5%-3.5% of component F. The disperse dye composition is very suitable for dyeing and printing on polyester / spandex fibers, has the advantages of excellent compatibility and high dye-uptake rate, has excellent color fastness to sunlight, color fastness to rubbing, color fastness to sublimation and various other excellent fastnesses on polyester / spandex textiles, especially has very high color fastness to washing, and is one of high-color-fastness-to-washing series products.

Description

[0001] This application is a divisional application with the application number 201110211817.X, the application date is July 27, 2011, and the invention name is "a disperse dye composition for polyester and spandex fiber dyeing and printing". technical field [0002] The invention relates to a disperse dye composition, in particular to a disperse dye composition suitable for polyester spandex fiber dyeing and printing. Background technique [0003] The dye blending technology is becoming more and more sophisticated, and various compound blending dyes are changing with each passing day, and dark disperse dyes occupy the largest proportion, especially black and blue dyes. In this regard, the industry has introduced a variety of black dyes that are compounded and blended. And although the black disperse dyes on the market are all excellent in every dyeing performance on the polyester fiber, the dyeing performance on the increasingly popular polyester spandex fiber needs to be f...
