| Abstract: |
The present invention relates to improvements in puncture-resistant and medicinal treatment garments. Garments made from fibers such as KEVLAR® and designed to deter penetration of objects are subjected to an additional brushing step to enhance the fibers' abilities to prevent penetration of sharp needle-like penetrating objects. The fibers may also be coated with an abrasive material to further engage and deflect penetrating objects. In another aspect of the invention, the fibers may be coated with a disinfectant or pharmaceutical agent. The coated fibers, having the improved fiber structure resulting from the brushing step, may be used in fabrics to treat skin conditions, disinfect penetrating objects in puncture-resistant materials, or as a disinfecting prevention fabric for use in textiles in high risk infection areas such as hospitals and public facilities.

I claim:
1. In the method of making garments having improved puncture resistance against sharp penetrating objects including the steps of providing a fiber having puncture-resistant properties, producing a plurality of individual fibrils from said fiber, forming said fibrils into a yarn and manufacturing a puncture-resistant garment from said yarn, the improvement comprising the step of brushing said yarn with an abrasive device to loosen the ends of said fibrils, said loosened ends of said fibrils providing enhanced puncture-resistance by crossing and covering holes between yarns and intertwining, thereby providing increased surface area to engage a sharp penetrating object.
