By adopting the technical scheme, the disperse orange S-4RL, the disperse ruby S-5BL and the disperse deep blue HGL are disperse dyes. The milk filaments are poor in alkali resistance and low in dye uptake in an alkaline environment, and glacial acetic acid is used for adjusting the pH value of the dye to be acidic and enhancing the dye uptake of the milk filaments. The addition of the neutral salt can reduce the solubility of the protein in the milk shreds, namely, can salt out the protein, thereby reducing the hydrolysis of the protein in the milk shreds during dyeing and improving the color fastness. Dodecyl glucoside belongs to nonionic surfactant alkyl glucoside, is colorless transparent liquid, is easily soluble in water and common organic solvents, and has long-chain molecules of hydrophilic polar groups and hydrophobic nonpolar groups. Peregal O is a nonionic surfactant, mainly comprises polyoxyethylene fatty alcohol ether, is in the form of cream or beige ointment, can be frozen when meeting cold, is easily dissolved in water, and is in a stable state in hard water, acid liquor or alkali liquor.
The invention is further configured to: the neutral salt is at least one of sodium sulfate and potassium sulfate.
By adopting the technical scheme, the sodium sulfate and the potassium sulfate have good water solubility, are common neutral salts, and are cheap and easily available. Sulfate ions in the sodium sulfate and potassium sulfate can improve the stability of protein conformation in the milk silk, thereby reducing the hydrolysis of protein in the milk silk during dyeing and improving color fastness.

By adopting the technical scheme, the benzotriazole ultraviolet absorbent is a product with the largest yield and the largest variety in the ultraviolet absorbent, and has higher light absorption index within 300-385 nm; before absorbing light, the ultraviolet absorbent exists in the form of phenol compounds, because the electron density on an oxygen atom is far greater than that on a nitrogen atom of a triazole ring, so that the phenol compounds are strongly alkaline, the electron density is mainly moved from the oxygen atom to the nitrogen atom of the triazole ring by the absorption of light, the phenol is more acidic, the nitrogen atom is more alkaline, and protons are rapidly transferred to the nitrogen atom to form tautomers. This tautomer is unstable and can safely convert excess energy to thermal energy, returning to a more stable ground state. The entire tautomerization process is extremely efficient and can be repeated almost indefinitely, which is why the compounds are photostable.
The invention is further configured to: the benzotriazole ultraviolet absorbent is one of UV-P, UV-327.
