Abstract: The present invention discloses opaque and white monofilaments that retain tensile strength even after exposure to high levels of UV light. Monofilaments of the present invention do not become brittle even after exposure to the equivalent of three to six months of Florida sun. Monofilaments of the present invention can be useful in brushes, filtration media, monofilament fabrics, synthetic hair for wigs, doll hair, and other applications where monofilaments can be used that are stored or sold in an environment where there is a substantial degree of exposure to the sun.

Abstract: The present invention discloses filaments with varying diameter along its length. This variation in diameter along the length of the filaments, when assembled into a toothbrush tuft improves both the interproximal cleaning and the scrubbing effectiveness of the toothbrush.

Abstract: A filament, brush and application package using a chemically tipped synthetic filament, where the filament contains a mildly abrasive additive such as clay and is mildly crimped. This synthetic filament improves product pick up for application to a designated surface.

Abstract: A brush for use in cleaning teeth, and a method for cleaning teeth using such brush, in which bristles are used in the brush that are prepared from a composition containing a thermoplastic polymeric resin in admixture with a slip agent.

Abstract: Synthetic monofilaments or bristles made from a thermoplastic elastomeric composition containing an aluminum silicate. The synthetic monofilaments or bristles possess properties, such as stiffness, similar to those of natural bristles such as goat hair, but without the unwanted side effects of natural bristles or prior synthetic bristles. A method for making such synthetic monofilaments or bristles of various lengths and diameters having a desirable wavy appearance is achieved by post-conditioning or mechanically crimping the monofilaments. The synthetic monofilaments or bristles are capable of being formed into brushes of all types and for all uses, especially as cosmetic brushes.
