Abstract
The invention relates to a flock black vat dye with high fastness to chlorine bleaching and hot pressing. The dye comprises the following components in percentage by weight: 32 to 36 percent of dye monomer A, 22 to 26 percent of dye monomer B, 2 to 6 percent of dye monomer C, 1 to 3 percent of dye monomer D, 30 to 40 percent of dispersing agent, and 0 to 2 percent of dust laying oil. According to the national standard, the fastness to chlorine bleaching of the black vat dye provided by the invention can reach 4 to 5 grade, the fastness to hot pressing can reach 4 to 5 grade; moreover, dry rubbing fastness of the dye reaches 4 to 5 grade and wet rubbing fastness reaches 3 to 4 grade; and the dye has high build up property and high blackening and fully meets the requirements on performance of high-requirement frock products.
Description
Technical field
The present invention relates to a kind of black dyes, particularly a kind of frock is floated the black vat dye (vat direct black W-RBH) of high fastness to hot pressing with high anti-chlorine.
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, development along with society, the frock product faces the raising that fastness to chlorine-bleaching, fastness to hot pressing, 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, fastness to hot pressing AATCC standard all 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 vat direct black RB, chlorine floats fastness and fastness to hot pressing is low, and indices is difficult to reach requirement, 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, and make the dimmed cloth cover blackout of color and luster.Therefore, existing product can't satisfy growing customer requirement, comes the satisfying the market needs in the urgent need to the black product that a kind of high anti-chlorine floats high fastness to hot pressing.
Summary of the invention
The technical problem to be solved in the present invention provides the black vat dye that a kind of high anti-chlorine that is applicable to frock floats high fastness to hot pressing.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of frock is floated the black vat dye of high fastness to hot pressing with high anti-chlorine, it is characterized in that this dyestuff is composed of the following components:
Weight fraction is the dye monomer A such as chemical formula (1) of 32-36%,
Weight fraction is the dye monomer B such as chemical formula (2) of 22-26%,
Weight fraction is the dye monomer C such as chemical formula (3) of 2-6%,
Weight fraction is the dye monomer D such as chemical formula (4) of 1-3%,
Weight fraction is that dispersion agent sodium lignosulfonate and the weight fraction of 30-40% is the dust laying oil of 0-2%.
A kind of frock of the present invention prepares in accordance with the following methods with the black vat dye that high anti-chlorine floats high fastness to hot pressing: after will measuring vat dyes monomer filter cake, the dispersion agent sodium lignosulfonate 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 72 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 vat grey 3B that the dye monomer A that the present invention adopts can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, the environment-friendly type reduced olive T that dye monomer B can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, the environment-friendly type Vat Olive Green B that the environment-friendly type 3b vat red 3b F3B that dye monomer C can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, dye monomer D can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce.
After adopting technique scheme, the beneficial effect that the present invention obtains is: test by correlated performance, its fastness to chlorine-bleaching of black vat dye provided by the invention reaches the 4-5 level, fastness to hot pressing reaches the 4-5 level, and in addition, its dried fastness to rubbing reaches the 4-5 level, wet fastness to rubbing reaches the 3-4 level, and enhancing rate is higher, and the product pitch black degree is high, satisfies 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 1-5
Press data shown in the table 1, after filter cake, the dispersion agent sodium lignosulfonate making beating with vat dyes monomer A, vat dyes monomers B, vat dyes monomer C and the vat dyes monomer D of metering ratio, adopt the broken technology of wet-milling to pulverize grinding, grind and send to the spray-drying tower drying by pipeline after 72 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 black vat dye 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.
