ABSTRACT:
The present invention is an improved protective cover for use in protecting a wearer against liquid contact, even under highly demanding conditions. The present invention identifies previously ignored voids in seams as a chief cause of failure in protective garments and other covers in shielding against air, liquid or virus penetration over an extended period of time. By sealing the seams with adhesive so as to fully encapsulate fibers therein and reduce void size to less than 10 micron, the risk leakage through the cover is dramatically reduced.
