Abstract
The invention relates to a light grey vat dye with high fastness to hot pressing for tooling, which comprises the following components in percentage by weight: 5-7% of dye monomer A, 6-8% of dye monomer B, 2-6% of dye monomer C, 6-10% of dye monomer D, 2-6% of dye monomer E, 65-75% of dispersing agent and 0-2% of dust laying oil. The fastness to hot pressing of the light grey vat dye provided by the invention can reach 4-5 level in accordance with national standards; in addition, the fastness to chlorine-bleaching of the dye reaches 3-4 level, dry color fastness to rubbing of the dye reaches 4-5 level and wet color fastness to rubbing of the dye reaches 3-4 level, thereby fully meeting high requirements of the tooling series of product performances.
Description
Technical field
The present invention relates to a kind of gray dyes, particularly a kind of frock is with the light grey vat dye (vat grey W-BG) of high fastness to hot pressing.
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 the raising that fastness to chlorine-bleaching, fastness to hot pressing 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 hot pressing AATCC standard more than 4 grades.Use at present the comparatively general dyestuffs such as Vat Grey M, fastness to hot pressing is lower, indices is difficult to reach requirement, product especially for outlet, with regard to more difficult meeting the demands, and in the process of dyeing, because the flatiron variable color is serious, the customer requirement that can't satisfy is come the satisfying the market needs in the urgent need to a kind of light grey product of high fastness to hot pressing.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of light grey vat dye that is applicable to the high fastness to hot pressing of frock.
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 light grey vat dye of high fastness to hot pressing:
Weight fraction is the dye monomer A such as chemical formula (1) of 5-7%,
Weight fraction is the dye monomer B such as chemical formula (2) of 6-8%,
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 6-10%,
Weight fraction is the dye monomer E such as chemical formula (5) of 2-6%,
Weight fraction is that dispersion agent sodium lignosulfonate and the weight fraction of 65-75% is the dust laying oil of 0-2%.
Light grey vat dye of the present invention prepares in accordance with the following methods: 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 70 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 dye monomer C can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, the environment-friendly type Vat Dark Blue BO that the environment-friendly type Vat Blue RSN that dye monomer D can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce, dye monomer E can select Jiangsu Yabang Dyestuffs Co., Ltd. to produce.
After adopting technique scheme, the obtained beneficial effect of the present invention is: light grey vat dye provided by the invention can reach the 4-5 level according to its hot pressing fastness of national standard, in addition, it is the 3-4 level that the chlorine of this dyestuff floats fastness, dried fastness to rubbing is the 4-5 level, wet fastness to rubbing is the 3-4 level, 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 1-5
Press data shown in the table 1, after vat dyes monomer A, vat dyes monomers B, vat dyes monomer C, vat dyes monomer D and vat dyes monomer E filter cake, the dispersion agent sodium lignosulfonate 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 70 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 light grey 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 every fastness.Measurement result
See Table 2.
