Document Type and Number:
WIPO Patent Application WO/2023/121341
Kind Code:
A1
Abstract:
A method for manufacturing a thermally adhesive fiber web is provided. The thermally adhesive fiber web according to an embodiment of the present invention is implemented by including the steps of: (1) preparing 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 compound; (2) after transferring the first spinning solution and the second spinning solution to the end of a discharge port of one nozzle of an electrospinning device through different passages to avoid blending of the spinning solutions, 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 1μm; and (3) applying heat to the accumulated side-by-side-type thermally adhesive composite fibers to prepare a thermally adhesive fiber web. Accordingly, the fiber web itself has thermal adhesiveness. Therefore, the present invention is suitable for implementing a thermally adhesive fiber web which enables easy interfacial bonding to a heterologous material with a different material and structural specification and prevents pores formed in an initial stage from being closed during thermal bonding.
