Abstract

The invention provides a fur-with-frost dye and a preparation method thereof. The fur-with-frost dye is prepared from the following raw materials in parts by mass: 20-50 parts of acid dye, 10-20 parts of ammonium sulfate, 2-10 parts of fluorescent whitening agent, 2-5 parts of penetrant, 2-5 parts of sodium xylene sulfonate, 10-20 parts of white dextrin and 20-35 parts of anhydrous sodium sulfate; the preparation method of the fur-with-frost dye comprises the following steps: (A) weighing the raw materials and mixing for 1-3 hours to obtain a first powdery mixture; (B) pouring the first mixture into a pelletizer for pelleting to obtain the granular fur-with-frost dye. The dye-uptake of the prepared fur-with-frost dye is increased in the dyeing process, the content of the dye in the waste liquid is effectively reduced and the harm to the environment and the human body is reduced. The dye is prepared into the granular form, and therefore, the dust is greatly reduced and the harm to the using environment and the operating workers is reduced; the prepared fur-with-frost dye has excellent dyeing property and environmental protection performance.

Description

technical field [0001] The invention relates to the field of dye production, in particular to a grass frost dye and a preparation method thereof. Background technique [0002] Dye is a substance that can make a certain color adhere to the fiber, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes require a mordant to make the dye stick to the fiber. Archaeological data show that dyeing techniques have a history of more than 5,000 years in India and the Middle East. The dyes at that time came from animals, plants or minerals and were rarely processed. [0003] my country is a big textile country with complete upstream, midstream and downstream systems and a large dyestuff demand market. With the cancellation of textile quotas, my country's textile exports will further increase, which will undoubtedly further stimulate the domestic demand for my country's dyestuff products and expand its domestic market. In addition, with the d...
