A process for producing a sea-island-type composite spun fiber whose island component has a diameter of 1 µm or less, characterized in that an unoriented sea-island-type composite spun fiber having been spun at a spinning speed of 100 to 1000 m/min is drawn at a total draw ratio of 5 to 100 (superdrawn) at temperature higher than the glass transition temperatures of respective polymers constituting the sea component and island component of the sea-island-type composite spun fiber.

Cette invention concerne un procédé de production de fibre filée composite de type île et mer dont la composante île possède un diamètre inférieur ou égal à 1 µm, caractérisé en ce qu~une fibre filée composite de type île et mer non orientée ayant fait l~objet d~un filage à une vitesse comprise entre 100 et 1000 m/min est étirée selon un rapport d~étirage total compris entre 5 et 100 (superétirage) à une température supérieure à celles de transition vitreuse des polymères respectifs constituant la composante mer et la composante île de ladite fibre.
