Embodiment 1

[0058] Grind and mix 10 g of simethicone oil, 3 g of aluminum chloride and 1 g of polylactic acid fiber to obtain an initial mixture. After mixing 6g of white petrolatum, 30g of 1-hexadecanol, 5g of glycerin and 100g of water, stir and disperse evenly with the initial mixture to obtain whitening agent A.

Embodiment 2

[0060] Grind and mix 20g of simethicone oil, 8g of aluminum chloride and 3g of polylactic acid fiber to obtain an initial mixture. After mixing 8g of white petrolatum, 50g of 1-hexadecanol, 7g of glycerin and 150g of water, stir and disperse evenly with the primary mixture to obtain whitening agent B.

Embodiment 3

[0062] Grind and mix 25g of simethicone oil, 9g of aluminum chloride and 5g of polylactic acid fiber to obtain an initial mixture. After mixing 10 g of white petrolatum, 50 g of 1-hexadecanol, 7 g of glycerin and 200 g of water, they were stirred and dispersed with the primary mixture to obtain whitening agent C.

Abstract

The invention belongs to the field of textile or papermaking, and relates to the whitening of textiles or paper, in particular to a whitening composition which comprises white vaseline and aluminum chloride. The invention also relates to a preparation method and use of the whitening composition. The whitening composition provided by the invention has advantages of low carcinogenicity, environmental protection, health and no pollution, and has a whitening effect approximate to that of the conventional ordinary whitening agent.

Description

technical field [0001] The invention belongs to the field of textile or papermaking, and relates to textile or paper whitening, in particular to a whitening composition, and also to a preparation method and application of the whitening composition. Background technique [0002] Optical brighteners are widely used in detergents, textiles and paper products. The whitening principle of fluorescent whitening agent is to absorb the invisible ultraviolet light in the light, and emit visible blue light, which is superimposed with the yellow light emitted by fabric or paper, and complements each other to form white light, so as to increase the white light emitted by fabric or paper. [0003] So far, common fluorescent whitening agents mostly use 4,4'-bis(2-sodium styryl)biphenyl (CBS-X), 4,4'-bis[(4-anilino-6- Hydroxyethylamino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulfonic acid disodium salt (VBL), stilbene triazine derivatives (HST), Bistrithroat aminostilbene (BBU) etc. are ...
