NANOFIBER SHEET, METHOD FOR USING SAME, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/111014
Kind Code:
A1
Abstract:
A nanofiber sheet (10) is provided with a substrate layer (12) and a nanofiber layer (11) disposed on one side of the substrate layer (12) and containing nanofibers of a polymer compound. The nanofiber layer (11) has a peripheral end (17) with a thickness of 0.1-10 µm and has a gradation region (G) having a thickness that gradually increases inward from the peripheral end (17). The distance W1 between the peripheral end (17) of the nanofiber layer and a maximum thickness part (15) in which the gradation region (G) is thickest is 3 mm or more. This nanofiber production method comprises depositing nanofibers on a collecting part while moving a nozzle and/or the collecting part to produce a specific nanofiber sheet having a gradation region (G).
