    Abstract: A polymer bristle (100) for a liquid-applying brush such as a paint brush includes in cross section a central bore (95), an annulus (96) and preferably three radiating spokes (97) with parallel sides and rounded tips. The bristle is tapered from a thick end (101) that is bundled into the ferrule of a brush toward a thin end (103). The bristle may be flagged by slits (130).

    Abstract: Papermaker's forming fabrics including extruded thermoplastic monofilaments formed from a polymer blend consisting of from about 51%-90% pbw (parts by weight) of a poly(ethylene naphthalate) (PEN) polymer having a melt point of from 249° C. to about 278° C., most preferably between about 262° C. and 273° C., and an intrinsic viscosity of from 0.45 to about 0.95, preferably from about 0.65 to about 0.85, along with from about 49%-10% pbw of a poly(ethylene terephthalate) (PET) polymer having an intrinsic viscosity of between about 0.55 to about 1.05, preferably from about 0.85 to 1.0. Monofilaments formed from the novel polymer blend exhibit physical properties differing from those obtained from monofilaments formed of 100% PEN polymer, making them particularly suitable for use in weaving and processing the forming fabrics of the present invention.

    Abstract: Level (i.e., uniform diameter along the length thereof) and tapered (varying diameter along the length thereof) brush bristles include a central core having an outer wall and a pair of internal, semi-cylindrical passages separated by a central dividing wall. A plurality of spokes, or ribs, extend radially outwardly from the outer wall of the central core in planes other than the plane of the central dividing wall and also are spaced equidistant from each other about the circumference of the outer wall. Applicator brushes employing the aforementioned bristles also form a part of this invention.

    Abstract: Microcellular carbon filaments having a specific gravity about 20-30% less than conventional carbon fibers made of the same precursor resin are formed by foaming the precursor resin during spinning. These low density microcellular carbon filaments, which may also be hollow, have improved insulation properties compared with conventional carbon fibers, they have a higher than expected strength to weight ratio and adhere in a superior fashion to a variety of matrix materials.

    Abstract: Hollow carbon and graphite filaments having a specific gravity of about 20-50% less than conventional solid carbon fibers made of the same precursor resin are formed by spinning hollow precursor resin filaments. These low density hollow carbon filaments have improved insulating properties compared with conventional solid carbon fibers and have an excellent bending strength to weight ratio.
