20100159184 | POLY-TRIMETHYLENE TEREPHTHALATE SOLID CORE FIBRILLATION-RESISTANT FILAMENT HAVING A SUBSTANTIALLY TRIANGULAR CROSS SECTION, A SPINNERET FOR PRODUCING THE FILAMENT, AND A CARPET MADE THEREFROM - In a first aspect the invention is a solid core fibrillation-resistant, synthetic polymeric filament having three substantially equal length convex sides. The sides through substantially rounded tips centered by a distance “a” from the axis of the filament. Each rounded tip has a radius substantially equal to a length “b”. Each tip lies on a circumscribed circle having a radius substantially equal to a length (a+b) and the midpoint of each side lies on an inscribed circle having a radius substantially equal to a length “c”. The filament has a denier-per-filament in the range 10<“dpf”<35; the distance “a” lies in the range 0.00025 inches (6 micrometers)<“a”<0.004 inches (102 micrometers); the distance “b” lies in the range from 0.00008 inches (2 micrometers)<“b”<0.001 inches (24 micrometers); the distance “c” lies in the range from 0.0003 inches (8 micrometers)<“c”<0.0025 inches (64 micrometers); and the modification ratio (“MR”) lies in the range from about 1.1<“MR”< about 2.0. | 06-24-2010 |
