Abstract

The invention relates to a high washing fastness dispersed yellow and brown dye composition. The high washing fastness dispersed yellow and brown dye composition aims at overcoming the defects that a dye composition is poor in color fastness in the prior art. The high washing fastness dispersed yellow and brown dye composition is composed of, by weight, 20 % to 40 % of dispersed orange, 25 % to 50 % of dispersed golden yellow, 10 % to 20 % of dispersed red dye and 10 % to 20 % of dispersed yellow in a mixing mode, and the balances auxiliaries. The dispersed orange is the combination of one or more compounds shown in a formula (1); the dispersed golden yellow is the combination of one or more compounds shown in a formula (2); the dispersed red dye is the combination of one or more compounds shown in a formula (3); the dispersed yellow is the combination of one or more compounds shown in a formula (4); R7 in the formula (4) is -CH3 or -CH2CH3. When the high washing fastness dispersed yellow and brown dye composition is used for dyeing of spandex fabrics, the dyeing effect is good, the color fastness is good, and the quality of the spandex fabrics can be greatly improved.

Description

technical field [0001] The invention relates to a dye composition, in particular to a disperse yellow-brown dye composition with high washing fastness. Background technique [0002] In recent years, since spandex-containing fabrics have excellent resilience properties, are soft to the touch, and are comfortable to wear, they have been more and more widely used, such as polyester / spandex elastic fabrics made of polyester composites. At present, disperse dyes are mainly used for dyeing polyester / spandex elastic fabrics. Due to the structural characteristics of spandex, disperse dyes are easy to dye spandex and desorb at the same time, so the color fastness of this type of product is reduced. In addition, due to the existence of spandex, in order to avoid damage to the performance of spandex, high-temperature dyeing of polyester is limited, while low-temperature dyeing often makes it impossible for disperse dyes to dye polyester well, and the dyeing rate and promotion rate of ...
