| Zusammenfassung: | The utility model discloses a superfine composite stretch yarn and spinneret plate used by same. The cross section of the superfine composite stretch yarn is circular or heart-shaped; the filament number of the superfine composite stretch yarn is 0.15 dex to 0.4 dex. The spinneret plate used by the superfine composite stretch yarn comprises a spinneret plate body and spinneret orifices which are arranged on the spinneret plate body, and is characterized in that the spinneret orifices comprise circular orifices and heart-shaped orifices. The superfine composite stretch yarn has the advantages that the spinneret plate used by the superfine composite stretch yarn has spinneret orifices which are formed by combining circular orifices and heart-shaped orifices, so that normal fibre and heart-shaped fibre can be simultaneously produced in a production process; the superfine composite stretch yarn sprayed out by the spinneret plate has fine and smooth hand feeling, strong spinnability, strong hygroscopicity, and a g |
