Method for manufacturing thermally adhesive fiber web and thermally adhesive fiber web produced thereby

A method for manufacturing a thermally adhesive fiber web, comprising:

• (1) preparing respectively a first spinning solution in which a support component, which is a first polymer compound, is dissolved, and a second spinning solution in which a thermally adhesive component, which is a second polymer compound, is dissolved, the second polymer compound having a melting point at least 50° C. lower than that of the first polymer;
• (2) after transferring the first spinning solution and the second spinning solution to the end of a discharge port of one spinning nozzle of an electrospinning device through different flow passages, performing electrospinning such that the first spinning solution is discharged to a portion of the end surface of the discharge port and the second spinning solution is discharged to the remaining portion, thereby accumulating side-by-side type thermally adhesive composite fibers having a diameter of less than 1 μm;
• and
• (3) applying heat to the accumulated side-by-side type thermally adhesive composite fibers to prepare a thermally adhesive fiber web.
