摘要：
From the rheological theory, the combination of the rheological characteristic of melt spinning and principle of spinning, the paper researches the mathematical model of the velocity distribution and shear rate distribution when the melt flow in composite spinning sheath-core orifices. According to the mathematical model, the melt flow velocity and pressure characteristic of the composite spinning micropore are researched with the software of CFD-Fluent. The results for the design of composite spinning technology and components provide a good theoretical basis.
