 Abstract
Improvements of the UV-aging resistance of poly(p-phenylene benzobisoxazole) (PBO) filament yarns, spun yarns, and woven fabrics have been investigated after surface treatment in a continuous process by using polyurethane resin and UV-absorbing and/or UV-stabilizing agents. The UV-aging resistance of PBO specimens was evaluated by tensile strength and reduction rate measurements after exposing the samples to an M400 UV lamp and solar light. A mixture of UV-absorbing (Chiguard 234) and UV-stabilizing (Chiguard 944) agents was found to be more effective compared to individual agents for improving the UV-aging resistance of PBO.
