Abstract

991,224. Spinnerets. SNIA, VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. May 20, 1963 [May 29, 1962], No. 20010/63. Heading B5B. Artificial threads and fibres of profiled crosssection are made using a spinneret having individual passages the cross-sections whereof present a central core portion and two or more ribs radially disposed with respect thereto, said ribs increasing in width outwardly from the central core portion. Preferably the ratio between the width at the outer end of the individual rib and the length thereof varies from 1: 2 to 1: 6 and especially from 1: 3.5 to 1: 4.5. Fig. 1 shows such a spinneret having three ribs, and Fig. 2 the cross-section of a fibre melt-spun from such a spinneret.
