Abstract: ZN-P-type UV climate-resistant test machine was used to accelerate the aging process of PP anti- photooxidation aging spunbonds in this paper. The break strength and elongation of the PP anti-photooxidation aging spunbonds before and after experiment were tested to estimate its anti-aging properties, which were affected by the types and content of anti-aging agent, colour masterbatch and fixed quantify on the PP spunbonds. The results showed that the PP anti-aging spunbonds modified by hindered amine anti-aging agent displayed better anti-aging properties than the samples modified by UV anti-aging agent. Furthermore, it showed the best ratio of cost and performance with mass fraction of 2% ~ 2.2%. The anti-aging properties of PP spunbonds were affected considerablly by the addition of color masterbatch.
