WATER VAPOR-PERMEABLE MEMBRANE MATERIAL

摘要

A moisture-permeable separating membrane material includes a porous fluororesin membrane, a continuous moisture-permeable resin layer formed on the surface of the porous fluororesin membrane, and a textile layer for reinforcing the porous fluororesin membrane and the continuous moisture-permeable resin layer. The textile layer contains a flame retardant in the inside of each fiber and the surface of each fiber has been treated with a flame retardant. The moisture-permeable separating membrane material makes it possible to improve flame retardancy without deteriorating heat exchange characteristics.
