Protective clothing

Abstract

Abstract PROTECTIVE CLOTHING IS MADE OF HIGHLY AIR-PERMEABLE CLOTH THAT HAS BEEN TREATED WITH AN OLEOPHOBIC AND HYDROPHOBIC COMPOUND AND A LINING OF ABSORBENT CHARCOAL LYING ON THE SURFACE OF THE CLOTH INSIDE THE GARMENT. THE PROPORTIONS OF LIQUID REPELLENT AND CHARCOAL APPLIED TO THE CLOTH ARE SUFFICIENT TO PROVIDE AN EFFECTIVE BARRIER TO THE INWARD PASSAGE OF CORROSIVE OR TOXIC CHEMICALSBOTH LIQUIDS AND GASES-FROM THE OUTSIDE BUT INSUFFICIENT TO REDUCE SERIOUSLY THE AIR PERMEABILITY OR TO PREVENT THE OUTWARD PASSAGE OF THE WEARER''S PERSPIRATION FROM THE INSIDE. THE CLOTHING MATERIAL IS MADE BY FIRST TREATING THE HIGHLY PERMEABLE CLOTH WITH A KNOWN OLEOPHOBIC AND HYDROPHOBIC FLUOROCARBON COMPOUND; EXCESS OF THIS MATERIAL IS SQUEEZED OUT AND THE TREATED CLOTH DRIED, AND THEN A NON-PENETRATING ADHESIVE SURFACE COATING OF A VEHICLE CONTAINING PARTICLES OF ACTIVATED CHARCOAL IS SPRAYED ONTO ONE SIDE OF THE CLOTH. THE CLOTHING MATERIAL MAY THEN BE GIVEN A KNOWN FIREPROOFING TREATMENT. SUCH MATERIAL AND CLOTHING IS A PROTECTIVE BARRIER AGAINST CORROSIVE OR TOXIC SPRAYS OR MISTS IN LIQUID OR VAPORISED FORM.
