摘要

The present invention relates to a multi-layered PTFE hollow membrane for membrane distillation and a manufacturing method thereof. The multi-layered PTFE hollow membrane for membrane distillation according to one embodiment of the present invention shows high removal efficiency of particulate contaminants through the control of fine pores and improves backwash efficiency by utilizing pores in an outer active layer as a filter layer by minutely adjusting the pores. The multi-layered PTFE hollow membrane for membrane distillation includes: a hollow; a PTFE support layer which is formed along the outer periphery of the hollow; and a fluorine resin layer with a melting point lower than the melting point of the PTFE support layer.
