This research mainly used the anti-ultraviolet ray medicament spreads on the aromatic polyamide anti-ball fibrous material by the titanium dioxide and UV-531, by way of ultraviolet ray illumination (UV lamp tube), discusses the aromatic polyamide bulletproof material the machinery and the bulletproof nature. Changes the anti- ultraviolet ray medicament the recruitment and the type carries on the processing, may know the increase ultraviolet ray absorbent the aromatic polyamide fabric has not increased the absorbent the force to have to be better than, takes advantage of this the full understanding aromatic polyamide mechanical property and the bulletproof performance influence.
