Abstract (en)

A hollow thermoplastic synthetic polymer filament includes a core portion having N number (typically, three or four) lobes joined thereto. Stiffening ribs are formed in the core portion. The stiffening ribs cooperate to define at least N hollow regions in the core portion. The hollow regions may communicate or be isolated from each other. Each lobe has at least one transverse stiffening web therein that prevents the lobe lateral edges from being deformed towards the exterior of the filament. The major portion of each lateral edge of each lobe may be substantially linear or convexly curved over substantially its entire length. A spinneret plate for producing the filament is also disclosed. <IMAGE>
