The present invention relates to a manufacturing method of nanofibers and, more particularly, to a manufacturing method of a waterproofing and moisture-permeable fabric using bottom-up electrospinning. The waterproofing and moisture-permeable fabric is manufactured by a bottom-up electrospinning device comprising a plurality of nozzle pipes inside a unit of the bottom-up electrospinning device, and has different basis weight of nanofibers in CD direction. By designing a nozzle block in the CD direction to be two parts, three parts, or nine parts, the manufacturing method of the waterproofing and moisture-permeable fabric can adjust the basis weight of a particular section in the same nanofibers to be different. |
