Abstract: The present invention relates to a tissue suitable for use in the disinfection of hard surfaces, instruments and human or animal skin or as a sheet inclusion in a washing process for the purpose of disinfection or bleaching. The tissue comprises first and second substrate layers which are bonded together with an adhesive polymer. This polymer also retains solid particles between the layers, which particles, when dampened with a suitable liquid become active and release chlorine. Preferably, the adhesive polymer comprises either a copolyester, copolyamide or polyethylene hot melt adhesive powder or an ethylene vinyl acetate (EVA) or modified EVA hot melt adhesive powder with a particle size between 0 and 750 microns inclusive.

Abstract: A container is provided having a hinged lid; a heating element in the container includes a fabric having resistance wires woven into it. The fabric has selvedges, each containing a conductor to which the resistance wires are connected in parallel. The heating element is flexibly deformable and is stretched by tensioning elements. An article placed on the heating element is urged into intimate contact with it by a resiliently deformable pad.

Abstract: An impregnated fabric material comprising a fabric substrate to which has been bonded an active cationic impregnant characterized in that there has also been applied to the substrate an anionic indicator dye in combination with a further cationic component, and in that the dye bonds to the further cationic component more readily than to the substrate and that the further cationic component competes with the impregnant for bonding to the dye. In the case of a wiping cloth, when the dye, which can act as an indicator, has been removed to indicate exhaustion of the active component, enough active component in fact remains on the cloth to provide a safety margin.

Abstract: An electrostatic imaging sheet wherein one side of the sheet, e.g. paper, is electrically conductive and the other side of the sheet has a continuous dielectric layer comprising a mixture of a smectite clay e.g. a synthetic hectorite swelling clay and an electrically insulating polymer, preferably in particle form. The dielectric layer may comprise a layer of a smectite clay which forms a barrier between the electrically conductive layer and the layer of insulating polymer.The invention is also a dielectric coating composition comprising a mixture of electrically insulating polymer in aqueous dispersion and a water dispersible smectite clay.The mixture of polymer and water dispersible smectite clay, preferably form a colloidal suspension, and the amount of smectite clay in the composition is preferably in the range 0.5 to 5% by weight of the composition excluding inorganic filler.

Abstract: The invention is a method of indicating the presence of an impregnant, e.g. an antimicrobial composition, in cloth to provide visual evidence of the continuing activity of the impregnant. The antimicrobial composition in the cloth is activated on contact with a liquid such as water and is ionically bonded to the cloth. Small portions of the impregnated cloth are dyed with an indicator dye which bonds preferentially to the antimicrobial composition so that when the antimicrobial composition is exhausted, the dye will disappear from the cloth. The dye is preferably applied to the cloth in stripes.
