【Abstract】 In this paper,a mathematical model describing downward hollow fibre melt-spinning process with self-suction of feeding gas at a controlled pressure tube-in-orifice spinnerette was presented.It was verified by experimental data.Through the analysis of computational calculation results,some helpful rules were obtained for practical stretch-made hollow precursor fibre melt-spinning operation.更多还原
