Using 1.0 dpf Orlon staple, the effect of surface treatments of the fibers upon ballistic performance was investigated. Agents which increased the normal fiber-to-fiber fraction were found to decrease the limiting velocities of their carded batts. Of the materials tested, hydrophobed aerogel produced the most pronounced effect. A curve was prepared of areal density versus limiting velocity for 1.5 Dacron staple. This polyester fiber has the smallest diameter commercially available. A plot was also obtained for Dynel staple fiber showing the effect of fiber diameter denier upon ballistics. The deniers ranged from 0.6 to 24.0. As expected, the limiting velocity decreased with increasing denier. Significant upgrading of the ballistic performances of 1.0 dpf Orlkon batts was not obtained as the result of incorporating nylon body armor into the structures. Author modified-PL.
