The three coordinates (L*, a*, and b*) of the CIELAB color system and the color difference (ΔE) of the fabrics were measured by colorimetry software. Measurements were performed under standard illuminant D65 and at a 10° observing angle. Electrical surface resistivity of the fabrics was measured in the warp direction using a standard two-probe method (AATCC test method 76-2005, electrical surface resistivity of fabrics) by means of Sa-Iran digital multimeter model 8515. UV-blocking properties of the cotton fabrics were evaluated according to AATCC test method 183-2004 (transmittance or blocking of erythemally weighted UV radiation through fabrics). The ultraviolet protection factor (UPF) rating system measures the UV protection provided by fabric. The UPF is defined as the ratio of the average effective irradiance calculated for skin to the average UV irradiance calculated for skin protected by the test fabric. The UPF was calculated using mean percentage transmission in the UVA region (315–400 nm) and mean percentage transmission in the UVB region (280–315 nm) by the equation
