Problems solved by technology

With the development of new synthetic fibers and polyester microfiber textile fabrics, especially the increasingly popular blended fabrics of polyester superfiber and spandex, when these dyes are used to dye deep red, the washing fastness is very poor and the hue is dull. , heat migration resistance and sublimation fastness can not meet the requirements of use
Recently, yellow light red disperse dyes compounded by benzodifuranones, which are extremely bright blue light red and bright yellow, are often used instead. The coloring of disperse dyes is slow and requires a higher dyeing temperature. This kind of compound dyes have poor compatibility and are prone to problems during the dyeing process

Abstract

The invention relates to a disperse scarlet dye composite. The composite contains one or more of materials of component A shown in the formula (1) and one or more of materials of the component B shown in the formula (2). The disperse scarlet dye composite is especially suitable for the dyeing of polyester-polyurethane blend fabrics, the color is similar to C.I. and disperse red 153 and is suitable to be used as main color; and the dye composite is characterized by good deep dyeing property, excellent color fastness and good levelling property.

Description

Technical field: [0001] The invention relates to a disperse dye, more specifically to a disperse scarlet dye composition. Background technique: [0002] Scarlet is a kind of bright yellow red, and disperse scarlet is one of the basic colors of commercial disperse dyes. It can be used alone or as an important component to make other bright colors. Disperse Red 54, C.I. Disperse Red 74, and C.I. Disperse Red 153 are common in Disperse Scarlet. With the development of new synthetic fibers and polyester microfiber textile fabrics, especially the increasingly popular blended fabrics of polyester superfiber and spandex, when these dyes are used to dye deep red, the washing fastness is very poor and the hue is dull. , heat migration resistance and sublimation fastness can not meet the requirements of use. Recently, yellow light red disperse dyes compounded by benzodifuranones, which are extremely bright blue light red and bright yellow, are often used instead. Disperse-like dyes...
