| Abstract: | The rheological behavior of low-melting point polyester chip was studied. The sheath-core ratio, compounding ingredient of the sheath ,chip drying process and drawing process were discussed for the composite spinning of low-melting point and normal polyester chips. The results showed that low-melting polyester melt belongs to pseudoplastic non-Newtonian fluid. The produced fiber exhibited better properties when the sheath-core ratio was 50/50, the sheath contained 70% low-melting point polyester and 30% normal polyester, and normal polyester was used as the core. |
