Problems solved by technology

[0002] At present, the gray dyes used by printing and dyeing factories for the medium and light color dyeing of polyamide fiber fabrics such as nylon and nylon fabrics generally use A-BL mixed with C.I. Acid Blue 324, C.I. Acid Yellow 199, and C.I. Acid Red 337. Composed of ash, although this kind of weak acid dye is cheap, it has many defects, not only poor heat sensitivity, but also low light fastness and wet fastness, which urgently needs to be improved.

[0029] Component A I-1 72

[0030] Component B II-1 9

[0031] Auxiliary Yuanming powder 45

[0032] Take the above-mentioned components, add 200g of water, beat for color matching, proofread the shade, and spray dry. The dye can provide uniform gray color with good fastness to the fabric.

Abstract

The invention discloses an acid gray dye composition, which mainly contains component A of one or more compounds with the structure shown in formula (I) and one or more components with the structure of the compound shown in formula (II) B, based on the component A and component B, the weight percentage of the component A is 60-95%, and the weight percentage of the component B is 5-40%. The acid gray dye configured by the acid gray dye composition prepared by the present invention has excellent fastness and heat sensitivity, and when dyeing protein fibers and their blends, polyamide fibers and their blends, etc. It has good color fastness and dye uptake.

Description

(1) Technical field [0001] The invention relates to an acid gray dye composition, in particular to an acid gray dye composition suitable for printing and dyeing protein fibers such as wool and its blends, silk, nylon and the like, and polyamide fibers and their blends. (2) Background technology [0002] At present, the gray dyes used by printing and dyeing factories for the medium and light color dyeing of polyamide fiber fabrics such as nylon and nylon fabrics generally use A-BL mixed with C.I. Acid Blue 324, C.I. Acid Yellow 199, and C.I. Acid Red 337. Composed of ash, this kind of weak acid dye is cheap, but it has many defects, not only poor heat sensitivity, but also low light fastness and wet fastness, which urgently need to be improved. Chinese patents 200610088065.1 and 200410041035.6 respectively introduce two kinds of acid composite gray dyes suitable for dyeing nylon and nylon fabrics in medium and light colors, which improve the heat sensitivity and the staining ...
