Abstract

1,057,181. Melt spinning lobed filaments. SWIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. March 16 1964 [March 22, 1963], No. 10924/64. Heading B5B. Filaments consisting of synthetic organic thermoplastic polymers have the shape of narrow ribbons provided on at least one side with a number of parallel longitudinal fins which are integral with and perpendicular to the main portion of the filament, the crosssection of the filaments having a denticulate appearance and the main portion of the filament being considerably thinner than the fin portion. The fins may have a flat shape. The filaments may be produced by melt spinning the polymer through spinnerets provided with extrusion orifices comprising a main straight slot having on one side a number of lateral straight slots branching therefrom and at right angles to the main slot, which is considerably narrower than the lateral slots.
