Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.

Abstract: Corrosion protection of magnesium and aluminum alloys in engine coolants and heat-exchange fluids is achieved by the use of a select group of aliphatic and aromatic carboxylate acids or the alkaline metal, ammonium or amine salts thereof in combination with a fluoride and/or a fluorocarboxylic acid or salt thereof. These compositions have been found to significantly improve the high temperature magnesium corrosion protection properties of coolants, and are of use in automobile engine coolant systems.

Abstract: In a method and apparatus for sizing a yarn sheet, the yarn sheet is passed over rollers through a wetting unit and a following roller nip that reduces the moisture content to a selected level. The wetted yarn sheet then passes through a sizing unit and over rollers forming a nip to reduce the sizing content to a desired level. The rollers of the wetting unit and the rollers of the sizing unit are in close proximity to minimize the reach of the yarn sheet there between and thereby minimize the heat loss in the yarn sheet. The reach is covered by a cover having a heater that extends over the yarn sheet reach to maintain the yarn sheet at a desired temperature as it enters the sizing unit. The temperature of the wetting agent bath in the wetting unit is 65°-95° C., with the temperature of the wetting agent being approximately 5°-10° C. higher than the temperature of the sizing agent bath.
