Dye-based UV protection fabrics are textiles treated with special dyes that absorb or block ultraviolet (UV) radiation, enhancing the fabric’s ability to shield the skin from harmful sun exposure. Unlike untreated fabrics, these materials incorporate UV-absorbing chemical dyes during the dyeing process, giving the fabric a higher Ultraviolet Protection Factor (UPF) rating while maintaining softness, breathability, and color vibrancy.
