摘要： An improved stretchable filtration fabric laminate is provided. The laminate includes a first fabric layer and a nanofiber layer. The laminate may be stretched without damaging the laminate. The laminate is thus suitable for incorporation into wearable protective garments, such as protective hoods, balaclavas, scarves, etc. that provide both protection and air filtration to the wearer.
