preparation example Construction

[0017] A kind of preparation method of the grass frost dyestuff provided in this embodiment comprises the following steps:

[0018] Adding dispersant NNO, dispersant SN, penetrating agent T and Yuanming powder to the disperse dye in parts by weight, mixing, performing grinding, drying and pulverizing treatment, to obtain dry pulverized disperse dye;

[0019] In parts by weight, add acid dyes, nonionic surfactants, fluorescent whitening agents, white dextrins, and sodium sulfate to the pulverized disperse dyes, mix and stir for a first predetermined time, and fully mix to obtain powdery grass Frost dye.

[0020] Preferably, in the step by weight, add acid dyes, nonionic surfactants, fluorescent whitening agents, white dextrin, and sodium sulfate to the pulverized disperse dyes, mix and stir for a first predetermined time, so that they are fully mixed , in obtaining the powdered grass frost dye, the first predetermined time is 2 hours to 5 hours.

[0021] Further, the step is ...

preparation example 1

[0033] Frost dyestuff on grass comprises the disperse blue 107 of 50 parts by weight, and it is made into disperse blue 107 filter cakes, the dispersant NNO of 10 parts by weight, the dispersant SN of 20 parts by weight, 5 parts by weight of penetrating agent T, 5 parts by weight of sodium sulfate and disperse blue 107 filter cake were mixed together, and the mixture was put into a sand mill. Add deionized water to the sand mill, the ratio of the weight of the deionized water to the weight of the mixture is 0.7, sand mill for 3 hours, make it fully mixed, and obtain the dye paste. The dye slurry was dried at 55°C for 74 hours, and after drying, it was pulverized in a pulverizer to obtain the treated disperse blue 107. Adding the leveling agent O of 5 parts in parts by weight in the processed disperse blue 107, the fluorescent whitening agent CBS-X of 8 parts in parts by weight, the white dextrin of 15 parts in parts by weight, the parts by weight It is 15 parts of Yuanming po...

Abstract

The invention discloses a snow top dye and a preparation method thereof. The preparation method of the snow top dye comprises the following steps: adding a dispersing agent NNO, a dispersing agent SN, a penetrating agent T and anhydrous sodium sulphate into a disperse dye in parts by weight, mixing, and dull polishing, drying and crushing the mixture to obtain the dry crushed disperse dye; and adding an acid dye, a nonionic surfactant, a fluorescent brightener, white dextrin and anhydrous sodium sulphate into the crushed disperse dye, and sufficiently mixing and stirring the ingredients at first preset time to obtain the powder snow top dye. The snow top dye prepared by using the preparation method disclosed by the invention is good in dyeing performance and environment protection performance.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a grass frost dye; in addition, the invention also relates to a preparation method for the grass frost dye provided by the invention. Background technique [0002] Along with the raising of people's living standard, fur clothing and fur accessories are also more and more subject to people's favor. Due to the development of fur clothing and fur accessories and the popularity of the style of frost on grass, frost on grass dyes have been paid more and more attention by many R&D personnel.
