High washing fastness dispersed black dye for superfine fibre
Technical field
The present invention relates to a kind of black dyestuff, relate in particular to a kind of black dyestuff that is used for ultra-fine fibre.
Background technology
At present, ultra-fine fibre has become the focus textile raw material that domestic and international each weaving manufacturing enterprise is used for developing grade textiles.Because ultra-fine fibre has minimal line density and high-specific surface area, makes its fabric have high spreadability, and is soft, comfortable and easy to wear, along with reducing of fibre number, the ratio that fiber surface specular scattering light accounts for increases, and makes the apparent tone of fabric relatively dimer, soft.Therefore, ultra-fine fibre is fit to make suede nap, peach face, emulation silk, simulate wool and highly dense series products, also can make imitation leather, clean-cloth, senior air filter, dust mask, skiing water-skiing clothing, swim suit and other moisture-permeability waterproof fabric etc.After entering 21 century, composite ultrafine fiber production technology and output are expected to occur bigger development, and what rate of growth was the fastest will be dacron ultrafine fiber.
Ultra-fine fibre surface area ratio conventional polyester is big, has therefore increased the surface reflection degree.The surface concn of product dyed thereby can reduce.Compare with the polyester of routine, surface-area is big, because used the high density dyestuff, therefore causes Exposure to Sunlight, sublimation fastness to reduce by 1~1.5 grade.Heat setting type after the reduction clearing influences because of moved by the heat treated thermophoresis of post-treatment, and washing fastness descends a lot.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of high washing fastness dispersed black dye for superfine fibre, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention is made up of Color Index (C.I.) Disperse Blue-60, C.I. Disperse Blue-79 .1, C.I. EX-SF DISPERSE BLUE EX-SF 300 77, C.I. DISPERSE YELLOW 114, C.I. Disperse Red 311, dispersion agent 85A (sodium lignosulfonate), dust laying oil (white kerosene); Its percentage composition is: C.I. Disperse Blue-60 7-10%, C.I. Disperse Blue-79 .115-22%, C.I. EX-SF DISPERSE BLUE EX-SF 300 777-10%, C.I. DISPERSE YELLOW 1145-8%, C.I. Disperse Red 3115-10%, dispersion agent 85A (sodium lignosulfonate) 45-50%, dust laying oil (white kerosene) 0.2-1%.
Compared with prior art, the invention has the beneficial effects as follows: can make the ultra-fine fibre lining dye dark thick black, have quite high washing fastness, light fastness simultaneously.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
The present invention is made up of C.I. Disperse Blue-60, C.I. Disperse Blue-79 .1, C.I. EX-SF DISPERSE BLUE EX-SF 300 77, C.I. DISPERSE YELLOW 114, C.I. Disperse Red 311, dispersion agent 85A (sodium lignosulfonate), dust laying oil (white kerosene); Its percentage composition is: C.I. Disperse Blue-60 7-10%, C.I. Disperse Blue-79 .115-22%, C.I.

Embodiment 1
Percentage composition of the present invention is: C.I. Disperse Blue-60 8%, C.I. Disperse Blue-79 .120%, C.I. EX-SF DISPERSE BLUE EX-SF 300 778%, C.I. DISPERSE YELLOW 1148%, C.I. Disperse Red 3116%, dispersion agent 85A (sodium lignosulfonate) 49.5%, dust laying oil (white kerosene) 0.5%;
Embodiment 2
Percentage composition of the present invention is: C.I. Disperse Blue-60 9%, C.I. Disperse Blue-79 .119%, C.I. EX-SF DISPERSE BLUE EX-SF 300 777.5%, C.I. DISPERSE YELLOW 1147%, C.I. Disperse Red 3116.5%, dispersion agent 85A (sodium lignosulfonate) 49.5%, dust laying oil (white kerosene) 0.5%;
The raw material that the present invention adopts can both have been bought on market.
Manufacture method of the present invention is: former dyestuff filter cake adds dispersion agent 85A (sodium lignosulfonate) and process heat water dissolution, grinds repeatedly and filters 48 hours, delivers to batch can, and spraying drying adds dust laying oil (white kerosene) and stirs finished product packing.The waste gas that produces in the spraying drying is by cyclone dust removal, and bag filter filters, and discharges as fuel oil waste gas and dust.
