Abstract

The invention relates to a sea island ultra-fine fiber special-black polyester dispersion dye with high color deepening capability and color fastness. The dispersion dye comprises the following components according to the weight percentage: 13-15 of Color Index C.I. dispersion blue 291, 13-15 of C.I. dispersion blue 291:1, C.I. 3-4 of dispersion blue 60, 5-6 of C.I. dispersion violet 93, 4-6 of C.I. dispersion orange 288, 4-6 of C.I. dispersion orange 61, 50-52 of dispersant, 1-2 of dust laying oil and 0.3 of dispersed complexing agent. The dispersion dye can obviously improve the exhaustion rate of dyes, obviously reduce the amount of the dyes in use, improve the color fastness and also reduce the sewage discharge and treatment.

Description

technical field

[0001] The invention relates to a black dye, in particular to a super-black disperse dye (disperse black DRD) of polyester sea-island type superfine fiber. Background technique

[0002] Polyester sea-island microfiber is a special kind of polyester fiber. For the same depth of color system, after dyeing at 130°C, the amount of dye used is several times higher than that of conventional polyester fibers. The dye exhaustion percentage in the dyeing liquor is low, the dye content in the sewage is high, and the color fastness of the dyed fabric is very poor. The market urgently needs products with high darkening properties, high dye exhaustion rate and high color fastness. Contents of the invention

[0003] The technical problem to be solved in the present invention is to provide a polyester sea-island superfine fiber ultra-black disperse dye with high depth and color fastness, aiming to solve the above-mentioned problems.

[0004] In order to solve the above...
