摘要
The present invention relates to meta-aramid hollow fiber and a manufacturing method thereof. The meta-aramid hollow fiber has enhanced thermal resistance, water permeability, and mechanical strength and can be applied to water treating membranes for precision filtration, ultrafiltration, or nanofiltration. The meta-aramid hollow fiber includes a porous sponge structure layer having an average pore size of 2-50 m; a dense structure layer which is formed on an outer side of the sponge structure layer and has an average pore size of 0.001-0.1 m.
