UV Shielding Treatment on Cellulose Film and Cotton Fabric Using Cerium-Calcium Hydroxyapatite Particles

Akemi Yasukawa, Keiko Gotoh

Abstract

Cerium-calcium hydroxyapatite (CeCaHap) solid solution particles were prepared with Ce/(Ce + Ca) = 0.01 by a wet method. The obtained particles were supported on cellulose film and cotton fabric by immersing them into the dispersion containing the particles. The morphology and ultraviolet (UV) shielding properties of the substrates supported by CeCaHap were investigated. The UV shielding properties of them were improved after the supporting and were further enhanced by pre-treatment using cationizing agent for both the substrates. The UV shielding ability was reduced by washing with water and an SDS solution for cellulose film, but the ability was kept well even after the washing for the cotton fabric. It is believed that the roughness of the surface of the cotton fiber contributes to the good ability.
