This text was extracted from a Microsoft Word document.
This is the abbreviated version, containing approximately 100% of the total text.

TOOTHBRUSHES, PAINT BRUSHES OR COSMETICS BRUSHES ARE MORE ATTRACTIVE WHEN FILLED WITH MONOFILAMENT BRISTLES MADE FROM COLOR STABILIZED NYLON. NATURAL COLOR MONOFILAMENT HAS A CLEARER APPEARANCE AND COLORED FILAMENT IS BRIGHTER. THE STABILIZED NYLON IS MORE RESISTANT TO HEAT ASSOCIATED WITH MONOFILAMENT PROCESSING CONDITIONS AND TO SUBSEQUENT HEAT POTENTIALLY ENCOUNTERED IN STORAGE CONDITIONS. THEREFORE, NYLON MONOFILAMENT BRISTLES DISCOLOR LESS, ENHANCING AND MAINTAINING A CLEAR AND/OR BRIGHT APPEARANCE OF THE BRUSH BRISTLES. THE NYLON MONOFILAMENT IS STABILIZED WITH A COMBINATION OF A PHOSHPORUS COMPOUND AND A GROUP IA BASE OR WITH A COMBINATION OF A PHOSPHORUS COMPOUND AND A MULTIVALENT METAL COMPOUND. PREFERRED COLOR STABILIZED NYLONS USED TO MAKE THE MONOFILAMENT ARE 612 NYLON, 610 NYLON, 66 NYLON AND COPOLYMERS THEREOF. THE PREFERRED COLOR STABILIZERS ARE DESCRIBED IN US 5,929,200 AND US 6,191,251.
