摘要
The microporous hollow fiber membrane is formed by walls with a system of slit-like micropores oriented in a lengthwise direction showing constant size and density of the micropores across the fiber and variable size and density along the fiber length such that the size and the density of the pores are lower towards the fiber ends. The invention also includes the method of preparation of the hollow microporous membrane fiber.
