  • Fluorpolymer sheets formed from hydroentangled fibers
    Patent number: 5422159
    Abstract: A sheet or web of fluoropolymer fibers, such as ethylene/chlorotrifluoroethylene fibers, which has been hydroentangled. Such hydroentangled sheets or webs may be employed as filters, masks, membranes, synthetic papers, industrial fabrics, or liquid separators for use in oil-in-water or water-in-oil emulsions.

  • Adherable, yet removable sheet material
    Patent number: 4783354
    Abstract: A sheet material which can be firmly adhered to a surface, and yet readily removed thereform, without the necessity of pre-wetting and without damaging the surface is prepared by coating one side of a base sheet with an adhesive composition containing a tacky, pressure sensitive adhesive, a wax, water, and an emulsifier. The adherable, yet removable nature of the sheet material does not degrade, but instead is maintained, over time. The sheet material is suitable for use as wallpaper, shelving paper, posters, note pads, labels, and the like.

  • Felt-like layered composite of PTFE and glass paper
    Patent number: 4324574
    Abstract: A felt-like layered composite of the following structure:a. a first layer of a predominantly horizontal coplanar superimposed layers of filamentary polytetrafluoroethylene components interrupted by occasional interlayered orientation;b. a thin high density nonwoven layer of fine glass staple fibers;c. a scrim fabric of polytetrafluoroethylene fibers andd. a second predominantly horizontal coplanar superimposed layers of filamentary polytetrafluoroethylene components interrupted by occasional interlayer orientation;wherein the layers are mechanically bonded together by filamentary polytetrafluoroethylene components extending vertically throughout the composite and a process for making this composite; the composite is useful as a filter fabric and is primarily used for bag filters to remove fly ash from the gaseous combustion products of coal fired furnaces and boilers.

  • Polytetrafluoroethylene felt
    Patent number: 4031283
    Abstract: An improved felt-like material made from filamentary polytetrafluoroethylene (PTFE) is provided. The improvement is the presence of fibrils of PTFE criss-crossing interstices of the felt. These improved felt-like materials have a higher air porosity, while maintaining as high a filtering efficiency, than the currently-used felt-like materials.

  • Processes for impregnating and coating triaxial weave fabrics
    Patent number: 4010306
    Abstract: An improvement in processes for impregnating and coating triaxial weave fabrics is provided. The improvement is laminating a lightweight sheet structure based on continuous filament synthetic organic fiber to the triaxial weave fabric and then impregnating and coating the laminate with a polymeric film using known techniques.
