Abstract: Anti-static cleanroom products having a coating of conductive polymeric particulates which decreases the surface resistivity of the products. Preferably, the particulates are pyrrole polymers. The anti-static properties are achieved by depositing conductive polymer particles onto the non-conductive substrate surface. The anti-static products include cleanroom wipers, stationery products (notebooks and writing instruments), garments and swabs (polyurethane foam tipped). The cleanroom stationery products include notebooks comprising polyethylene impregnated with silica. The invention also includes anti-static plastic gloves.

Abstract: A cleaning sheet with a tacky surface coating is used to clean feed rollers in copying machines or similar equipment and similarly-coated cloths are used for the removal of particles from other surfaces to be cleaned. The cleaning articles are made by printing the tacky material on sheet material such as paper or cloth. Relatively thick layers of tacky material are applied quickly and economically by the use of a multi-stage printing press which builds up a thick layer from a plurality of thin layers.

Abstract: A cleaning kit for use in cleaning surfaces in clean rooms, semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers is packaged together with a container of cleaning fluid in a liquid-tight outer container. The kit is stored until just before it is to be used. Fluid is released from the inner container into the wipers. In one embodiment, the inner container is frangible and is broken by application of hand pressure to the outside of the outer container. The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use. The container can be resealed to protect the wipers after the package has been opened. This device and method minimize deterioration of the wiper material due to prolonged contact with the cleaning fluid, and minimize the loss of effectiveness of substances such as biocides which might deteriorate due to prolonged contact with the wiper material.

Abstract: A cleaning kit for use in cleaning surfaces in clean rooms, semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers is packaged together with a container of cleaning fluid in a liquid-tight outer container. The outer container is vacuum-sealed. The kit is stored until just before it is to be used. Fluid is released from the inner container into the wipers, preferably by the use of a puncturing device operable to puncture one of the walls of the inner container by the application of pressure in a limited area on the outside of the outer container. The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use.

Abstract: A cleaning tape is edge-stabilized using an adhesive that is solvent resistant. The edge-stabilizing adhesive is a one-step cross-linkable formulation of polyvinyl alcohol, ammonium zirconium carbonate, an acetylinic surfactant and a non-silicone defoaming agent. The formulation is applied to the sides of a woven cotton cleaning tape roll and then is allowed to dry and cure. The resulting cleaning tape can be used in a surface buffing operation in which a solvent is applied to the cleaning tape, without contamination of the surface to be buffed by fibers from the tape or by the edge-stabilizing adhesive.

Abstract: An article of manufacture, such as a wiper, especially suited for use in a controlled environment, such as a cleanroom environment, and a method for controlling the entry of deleterious particles into the controlled environment, within which environment a process is carried out, the article being constructed of fibers of a synthetic polymeric material of the type including only constituents which are relatively benign in that the included constituents will be less likely to have a deleterious effect upon the process carried out in the controlled environment or upon the product of that process, the method including constructing the article of such fibers, the preferred synthetic polymeric materials including no more than only negligible amounts of inorganic constituents or metallic constituents, one such preferred synthetic polymeric material being nylon bright.

Abstract: The feed surfaces of feed rollers along the paper path of an imaging machine are cleaned by passing a cleaning sheet along the paper path through the imaging machine, the cleaning sheet including a substrate carrying a coating of synthetic polymeric material in a pattern which assures contact between the coating and the feed surfaces to be cleaned, the material of the coating having a tack which enables the coating to pick off particles of unwanted material from the feed surfaces and capture the picked-off particles for movement with the cleaning sheet along the paper path and out of the machine.

Abstract: A method and a wiper for reducing particulate contamination which otherwise might result from the use of the wiper in a controlled environment, such as that maintained in a cleanroom, the wiper being of the type constructed at least partially from a thermoplastic fabric material by severing the wiper along peripheral edges thereof from a sheet of such material having indeterminate dimensions, the method and the wiper providing a fused border in the material along the peripheral edges of the wiper and extending inwardly into the wiper a distance great enough to provide the fused border with sufficient area and sufficient tear-strength to maintain therein segments of the material of the wiper which otherwise might be released from the peripheral edges of the wiper during use of the wiper, yet small enough to maintain pliability and absorbency in the wiper for wiping procedures.
