Abstract
The invention relates to a dark black reducing dye with high colour fastness to chlorine bleaching for frock. The dye comprises the following components in percentage by weight: 12 to 16 percent of dye monomer A, 24 to 28 percent of dye monomer B, 6 to 10 percent of dye monomer C, 48 to 54 percent of dispersing agent and 0 to 2 percent of dust-resisting oil. The colour fastness to chlorine bleaching of the dark black reducing dye provided by the invention can reach 4 to 5 levels according to national standard. In addition, the fastness of the dye to hot pressing is 3 to 4 levels; the dry rubbing fastness is 4 to 5 levels; and the wet rubbing fastness is 3 to 4 levels. The dye has higher blackness degree and can completely meet the high requirements on properties of frock products.
Description
Technical field
The present invention relates to a kind of aterrimus dyestuff, particularly the special-purpose black vat dyes of high fastness to chlorine-bleaching (vat direct black W-RBN) of frock.
Background technology
Vat dyes is the high-grade dyestuff that a veriety is numerous, bright in colour, fastness is excellent, because vat dyes has good sun-proof, weather, heat-resisting, anti-solvent, washing fastness, can be widely used in the printing and dyeing of cotton, hair, silk, fiber crops, synthon and BLENDED FABRIC thereof, intertexture, be cotton with a kind of high-grade products in the dyestuff.
In recent years, along with the development of society, the frock product faces chlorine and floats the raising that fastness, high pitch black degree etc. require, simultaneously, European ﹠ American Market also has very high requirement to every colour fastness of polyster cotton tooling fabric, and especially medical tooling fabric requires fastness to chlorine-bleaching AATCC standard more than 4 grades.It is all better that general vat dyes chlorine floats fastness, such as red F3B, yellow G, bright green FFB, purple 2R etc. higher fastness to chlorine-bleaching is arranged, but use comparatively general such as dyestuffs such as B150reactive Black B 150 RB, fastness to chlorine-bleaching is low, and it is large to dye dark operation easier, especially for the product of outlet, with regard to more difficult meeting the demands, and in the process of dyeing, be damaged easily when product dyed thereby runs into available chlorine, can't dye deeply for special aterrimus.Therefore, existing product can't satisfy growing customer requirement, and the aterrimus product high in the urgent need to a kind of high fastness to chlorine-bleaching comes the satisfying the market needs.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of aterrimus vat dyes that is applicable to the high fastness to chlorine-bleaching of frock, and in addition, this dyestuff also has higher pitch black degree.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of frock is characterized in that this dyestuff is composed of the following components with the aterrimus vat dyes of high fastness to chlorine-bleaching:
Weight fraction is the dye monomer A such as chemical formula (1) of 12-16%,
Weight fraction is the dye monomer B such as chemical formula (2) of 24-28%,
Weight fraction is the dye monomer C such as chemical formula (3) of 6-10%,
Weight fraction is the dispersion agent of 48-54% and the dust laying oil of 0-2%.
As limitation of the invention further, dispersion agent of the present invention is sodium lignosulfonate.
Aterrimus vat dyes of the present invention can prepare in accordance with the following methods: after will measuring vat dyes monomer filter cake, the dispersion agent making beating of ratio, adopt the broken technology of wet-milling to pulverize grinding, grind and send to the spray-drying tower drying by pipeline after 85 hours, spray into simultaneously a certain amount of dust laying oil, the end product packing, the waste gas that produces in the spraying drying passes through for several times dust removal by filtration by cyclone dust collector.
The environment-friendly type reduced olive T that the dye monomer A that the present invention adopts can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, the environment-friendly type vat bordeaux 2R that the environment-friendly type vat grey 3B that dye monomer B can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, dye monomer C can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce.
After adopting technique scheme, the obtained beneficial effect of the present invention is: aterrimus vat dyes provided by the invention can reach the 4-5 level according to its fastness to chlorine-bleaching of national standard, in addition, the fastness to hot pressing of this dyestuff is the 3-4 level, dried fastness to rubbing is the 4-5 level, and wet fastness to rubbing is the 3-4 level, and, this dyestuff has higher pitch black degree, can satisfy high request frock series product performance fully.
Embodiment
The present invention is further detailed explanation below in conjunction with embodiment, but protection scope of the present invention is not limited to this.
Embodiment 1-4
Press data shown in the table 1, after vat dyes monomer A, vat dyes monomers B and vat dyes monomer C filter cake, the dispersion agent making beating with the metering ratio, adopt the broken technology of wet-milling to pulverize grinding, grind and send to the spray-drying tower drying by pipeline after 85 hours, spray into simultaneously the dust laying oil of amount as shown in table 1, the end product packing, the waste gas that produces in the spraying drying passes through for several times dust removal by filtration by cyclone dust collector.
Table 1
The navy vat dyes that above-described embodiment is made carries out the composite performance test, adopts respectively GB/T7069-1997, GB/T6152-1997, GB/T3920-1997 to measure its dyefastness.Measurement result sees Table 2.
