| Abstract: | The characterization and calculation of shear rate when polymer melt pass through the profiled spinneret were summarized.These gave some academic evidence about the design of spinnerent with different microporous shape.By the production practice process,the shear rate influencing factors and change law of several kinds of common profiled microporous shape were analysed.The concrete value range of the shear rate of different microporous shape was inducted. |
