Abstract: A method for manufacturing nanofiber is provided to produce a nonwoven fabric formed of continued nanofiber without beads, by mixing and spinning polymers having the same molecular structure and different molecular weights. A spinning solution is formed by mixing and dissolving a plurality of polymers in a solvent, wherein the polymers have the same molecular structure and different molecular weights(S110). The spinning solution is electro-spun and enriched to prepare nanofiber(S120). Each of the polymers has a weight percents of at least 10%, based on the total weight of the polymers. The plurality of polymers are polycaprolactone substances having different molecular weights.
