Abstract:

A functional protective clothing fabric composed of a fabric layer, a protective layer and a nano-TiO2 coating layer with good anti-ultraviolet and anti-electromagnetic radiation properties was developed. Specifically, the superfine silver plating polyester filament was used to fabricate the protective layer according to the reinforced twill weave. The peotective layer was conneced with the fabric layer according to the specially designed double layer weave. Nano-TiO2 was coated on the surface of the protective layer to form the anti-ultraviolet coating layer. The ultraviolet protection and anti-electromagnetic radiation performance of the fabric were tested, respectively. According to the principle of orthogonal test, grey cluster analysis was adopted to determine the optimal processing parameters. The results show that the ultraviolet protection coefficient, the average shielding effectiveness, the maximum shielding effectiveness and the corresponding frequency, the minimum shielding effectiveness and the corresponding frequency of the designed functional protective clothing fabric are 60.1, 99.992 0%, 99.998 9% and 120 MHz, 99.958 6% and 205 MHz, respectively.
