Abstract

The invention discloses a vat olive T liquid dye and a production process. A formula comprises the ingredients in percentage by mass: 18%-25% of benzanthrone, 18%-25% of 1-aminoanthraquinone, 1%-5% ofsoda ash, 0.1%-1% of a dispersant, 0.1%-1% of an anti-coagulationassistant and 50%-57% of water. The production process comprises the following steps: (1) material selecting; (2) vat olive T filter cake producing; (3) grinding; (4) rating; (5) dyeing analyzing; and (6) packaging and warehousing. According to the vat olive T liquid dye and the production process, through a specific proportioning ratio and the steps of vat olive T filter cake producing, grinding, rating, dyeing analyzing and packaging and warehousing, the prepared liquid dye can be clean and environmentally friendly, and dust pollution is reduced; during use in a printing and dyeing mill, the COD value of sewage is reduced; during production, energy is saved; the liquid dye is more bright-colored in color light compared with powder dyes; and during use, the vat olive T liquid dye is more convenient and is a genuine environment-friendly dye.

Description

technical field [0001] The invention relates to the technical field of dye production, in particular to a reduced olive T liquid dye and a production process. Background technique [0002] Vat dyes have won the reputation of "advanced dyes" in the dye market and people's concepts due to their excellent fastness since their inception, and vat olive T, as a large variety of vat dyes, occupies a very important position in it. With the increase of market demand, the quality requirements are becoming more and more strict. The original dyestuff is black brown filter cake of the reduced olive series T black powder, which is green when dissolved in concentrated sulfuric acid, and becomes black precipitate after dilution. In the medium, the leuco body is reduced to gray, and the acid state is dark olive green. It is mainly used for dyeing cotton fibers, generally not used for printing, suitable for suspension pad dyeing, and can be mixed with other vat dyes for dyeing Cotton and pol...
