ABSTRACT:
Multi-cavity filaments having improved resilience and anti-soiling properties have continuous cavities along their length with each cavity having a vertex angle formed by two sides or legs of the cavity of between about 65.degree. and 140.degree.. The vertex angle of each cavity points substantially toward the center axis of the filament. The cavities are spaced from each other and from the periphery of the filament in a manner producing a filament having good physical and aesthetic properties.
