  • Hot-melt adhesive polyester conjugate fiber
    Patent number: 8147956
    Abstract: To obtain an ultrafine heat-shrinkable conjugate fiber at high productivity, in which a flow-drawing state of a polyester undrawn yarn is realized easily and stably. By drawing undrawn yarn comprising a conjugated polyester polymer and olefin polymer, a flow-drawing process can be easily and stably realized using conventional production facilities; and the heat-shrinkable fiber, a drawn intermediate, and an ultrafine hot-melt adhesive conjugate fiber produced by redrawing the drawn intermediate of the present invention can be obtained with high productivity and excellent runnability. More specifically, the ultrafine hot-melt adhesive conjugate fiber obtained by redrawing can be drawn at a heretofore unseen high drawing magnification, and the fiber structure of the olefin polymer constituting part of the conjugate fiber is markedly developed.
