Zeolite gives a contribution to UV protection by scattering UV radiation unlike other agents which absorb this radiation preventing their transmission. Treated textiles achieved a high level of UV protection. FWA treatment leads to excellent UV protection for cotton and very good protection for polyester. Even though natural zeolites are yellowish they do not affect fabric whiteness significantly. It is to point out that nanoparticles of zeolite and FWA give off a synergistic effect in fabric UV protection.
