Title: John H Kozlowski: Innovator in Fiber Manufacturing
Introduction
John H Kozlowski is a notable inventor based in Vancouver, WA (US), recognized for his contributions to the field of fiber manufacturing. With a total of 3 patents, he has made significant advancements that have practical applications in various industries.
Latest Patents
One of his latest patents is a process for making fibers. This innovative method involves forming a mixture of a solvent, a polymer, and water, which is then flashed through a nozzle. In this process, water is present as a discontinuous phase in the mixture. The polymer used can be any capable of forming fiber, with a preference for crystalline or partially crystalline polymers such as polyethylene or polypropylene. The discrete fibers produced can be easily refined and utilized for making paper webs.
Another significant patent is the method of preparing a disalt of 3,3-sulfonylbis(6-hydroxybenzene). This process involves sulfonating 4,4'-dihydroxydiphenyl sulfone to create 3,3'-sulfonylbis(6-hydroxybenzene sulfonic acid). The product can be recovered from the reaction mixture by adding methanol or ethanol and a base, which selectively precipitates only the disalt of the product. This innovative product serves as a flame retardant additive in polymers and other materials, and it is also effective in boiler water to prevent scale formation.
