Among these textiles, there is a magical substance that is silently playing a role – polyurethane sponge whitening agent. It is like an invisible makeup artist, covering the textile with a white coat, giving it a charming glow.

What is polyurethane sponge whitening agent?

Polyurethane sponge whitening agent is a chemical additive that is mainly used to improve the color and appearance of polyurethane sponges. Its main function is to make textiles look whiter and brighter through optical principles. This whitening agent is usually a mixture of fluorescent whitening agents and other auxiliary ingredients. Fluorescent whitening agents absorb UV light and convert it into visible blue light, thus offsetting the possible yellowish tones in textiles and making the overall color whiter.

Basic Characteristics of Polyurethane Sponge Whitening Agent

  • Chemical Properties: Polyurethane sponge whitening agents are usually colorless or light yellow liquids or powders.
  • Physical form: It can be liquid, solid or granular, and the specific form depends on the production process and purpose.

For ordinary white textiles, a slight yellow or gray color may appear due to the influence of trace impurities or other factors on the fiber itself. At this time, polyurethane sponge whitening agent shows off his skills.

The whitening agent molecules contain chromophores of specific structures that can effectively absorb invisible ultraviolet light and convert them into blue visible light with longer wavelengths. The blue light complements the originally yellowish textile colors, and finally presents a purer white effect. This process is similar to the tricks in magic performances, but here, it is not the eyes that “disfies” but the light.

Specific process of optical whitening

  1. Absorbing UV rays: The whitening agent molecule preferentially absorbs ultraviolet rays with wavelengths in the range of 300-400 nanometers.
  2. Energy conversion: converts absorbed energy into an excited electron transition.
  3. Release blue light: Released in the form of blue visible light with a wavelength of about 420-470 nanometers.
  4. Visual Whitening: After the blue light is superimposed with the original color, the overall tone perceived by the human eye becomes brighter and whiter.
