Abstract: A medical gown (701) includes a layer of material (100) with a seam (401) disposed across the layer of material. The material can include a weave (110) of untwisted, continuous filament polyester. The material can also include a carbon filament (109). The seam is sealed by applying a tape (200) across the seam and applying heat to cause the tape to attach to the weave.

Abstract: A method of joining two panels of fabric comprises the steps of: placing the edges of the panels in register with each other to form a seam; wrapping the edge of at least one panel in fusible thread to create a treated edge; stitching the interfolded panels to join them to each other; and applying heat to the stitched seam to cause the fusible thread to melt.

Abstract: A high-security fabric for use in high-security applications comprising an inner layer of nylon having top and bottom surfaces, two inner layers of polyester, one of the inner layers of polyester extending on the top surface of the inner layer of nylon, the other inner layer of polyester extending on the bottom surface of the inner layer of nylon, and two outer layers of a fireproof synthetic fabric, each outer layer of fireproof synthetic fabric extending on one of the inner layers of polyester opposite to the inner layer of nylon. All of the layers form a 5-ply assembly having a top and a bottom and in which the inner layer of nylon is centrally positioned. The assembly is stitched together with a nylon thread in a pattern.

Abstract: A protective head gear comprising a plurality of concentric tubular rings formed of soft, yieldable material.
