Function:
Fluorescent whitening: Fluorescent whitening agent 220 can absorb invisible ultraviolet light and convert it into blue or purple visible light with a longer wavelength, which complements the yellow light of the matrix itself, thereby achieving a whitening effect, making the treated items look whiter, brighter and more vivid.
Improve gloss: By absorbing and re-emitting light, it can improve the optical properties of the surface of the object, making the surface of the object present a better gloss and improving the overall texture.
Enhance light resistance: To a certain extent, it can help protect the treated material from damage by ultraviolet rays and reduce the degradation of ultraviolet rays on the material, thereby improving the light resistance of the material and extending its service life.
Application:
Paper whitening: used in the production process of various papers, such as writing paper, printing paper, toilet paper, wrapping paper, etc., can effectively improve the whiteness and glossiness of paper, improve the appearance quality of paper, make paper look whiter and smoother, and enhance the grade and performance of paper.
Detergent industry: added to detergent, it can make washed clothes and fabrics whiter and brighter after washing, enhance the washing effect and whitening performance of detergent, and improve consumer satisfaction with detergent products.
