LIQUID WATER RESISTANT AND WATER VAPOR PERMEABLE GARMENTS |
摘要 |
A water resistant garment is disclosed having regions of high MVTR while maintaining water resistance. The garment has a fabric layer adjacent one major surface of a nanofiber layer. The surface of the nanofibers are coated with a coating containing a fluorocarbon polymeric moiety and a resin binder or extender which is soluble in water and/or other solvents. The coated nanofiber layer has a contact angle of greater than 145°. The garment optionally includes a second fabric layer adjacent the other major surface of the nanofiber layer. The garment has regions having a Frazier air permeability of between about 0.5 m3/min/m2 and about 8 m3/min/m2, an MVTR of greater than about 500 g/m2/day and a hydrostatic head of at least about 50 cmwc.
