  • Publication number: 20090305037
    Abstract: The present invention provides a conjugate fiber having excellent elastic extensibility and transparency. The present invention relates to a highly elastic conjugate fiber comprising an elastomeric resin (A) having elastic extensibility; and an elastomeric resin (B) having elastic extensibility, permanent elongation of 25 to 70% and a tensile elongation of 100 to 800%; a core comprising the elastomeric resin (A), and a sheath comprising the elastomeric resin (B).

  • Publication number: 20090269582
    Abstract: The present invention provides a process for producing a conjugate fiber that is excellent in strength, stretch elasticity, and transparency. The process includes a step (1) in which an elastomer resin (A) having stretching elasticity and an elastomer resin (B) having stretch elasticity, a permanent elongation of 25-70%, and a tensile elongation of 100-800% are separately melted and subjected to conjugate spinning using a conjugate spinneret having two nozzles so that the elastomer resin (A) forms a core and the elastomer resin (B) form a sheath; a step (2) in which the fiber obtained by composite spinning in the step (1) is heat-treated; and a step (3) in which the fiber heat-treated in the step (2) is stretched.
