  • PROCESS FOR MANUFACTURING A NONWOVEN SHEET MATERIAL HAVING AN IMPERMEABLE LAYER ON ONE SIDE AND AN ANTI-SLIP COATING ON THE OTHER SIDE
    Publication number: 20240035212
    Abstract: A process for manufacturing a nonwoven sheet material having an impermeable layer on one side and an anti-slip coating on the other side includes carding fibers with a common general orientation and forming a web. The fibers are bonded into a nonwoven sheet material. An anti-slip coating is applied onto one surface of the material. A polymer is applied onto the second surface of the nonwoven material. The orientation of the fibers is maintained during the entier process.

  • Emulsifier free aqueous emulsion polymerization process for making fluoropolymers
    Patent number: 6693152
    Abstract: Emulsifier free fluoropolymer manufacturing method in which (a) a mixture of an oxidizing agent and reducing agent is used to start the polymerization and where one or the other but not both, are further added during polymerization, or (b) an oxidizing metal ion is added to start polymerization and where additional oxidizing metal ion is added during polymerization.
