Description
Summary:In this study, conjugate fibers were prepared from 1,4-cyclohexanedimethanol-modified polyethylene terephthalate (PET) resin using side by side conjugate spinning, sea-island type conjugate spinning, and split type conjugate spinning methods, and the properties of the conjugate fibers were investigated via several techniques. When viscosity increased, the tenacity of side by side conjugate fibers was increased, whereas elongation decreased. The sea-island conjugate fibers showed lower weight loss and surface color difference (K/S) values relative to that of regular PET fibers at the same conditions. The SEM results indicate that orange type spilt readily produced at a temperature range of 120 - 140$^{\circ}C$.
