Abstract:
Moisture-permeable waterproofing layered fabric (9) includes a face fabric layer (2) and a nanofiber nonwoven fabric layer (3) disposed on one surface of the face fabric layer (2), wherein the nanofiber nonwoven fabric layer (3) has a water-repellent layer (5) on at least one surface thereof, and the face fabric layer (2) and the nanofiber nonwoven fabric layer (3) have been partly bonded with an adhesive (4). A production method for this moisture-permeable waterproofing layered fabric comprises applying and fixing a water repellent to at least one surface of the nanofiber nonwoven fabric layer (3) to thereby form the water-repellent layer (5) and partly bonding the nanofiber nonwoven fabric layer (3) and the face fabric layer (2) with the adhesive (4). Thus, provided are: moisture-permeable waterproofing layered fabric which, when being worn, can keep up the air permeability and moisture permeability of the moisture-permeable film even in rain or sweating; the production method therefor; and a garment.
