Abstract
Official abstract text for this publication.
A partition member for total heat exchange element ( 14 ) includes an ultrafine fiber portion ( 17 ) on a porous sheet ( 18 ). The ultrafine fiber portion ( 17 ) is impregnated with or coated with a moisture permeable substance ( 21 ), and water-insolubilized.
First claim
Opening claim text (preview).
1 . A partition member for total heat exchange element, the member comprising: a porous sheet; and an ultrafine fiber portion provided on the porous sheet, wherein the ultrafine fiber portion is impregnated with or coated with a moisture permeable substance and water-insolubilized. 2 . The partition member for total heat exchange element according to claim 1 , wherein the ultrafine fiber portion is structured of ultrafine fibers having a fiber diameter of 0.1 μm or more and 3 μm or less, the porous sheet has an average pore diameter of 15 μm or more and 100 μm or less and a thickness of 20 μm or more and 500 μm or less, and the ultrafine fiber portion has an average pore diameter of 0.01 μm or more and 10 μm or less and a thickness of 0.5 μm or more and 20 μm or less. 3 . The partition member for total heat exchange element according to claim 1 , wherein the moisture permeable substance is turned into macromolecules by impregnation or coating of a low-molecular-weight hydrophilic organic compound, followed by polymerization of the low-molecular-weight hydrophilic organic compound. 4 . The partition member for total heat exchange element according to claim 1 , wherein the porous sheet contains a heat-fusing component, and after the porous sheet and the ultrafine fiber portion are thermally bonded to each other, the ultrafine fiber portion is impregnated with or coated with the moisture permeable substance. 5 . The partition member for total heat exchange element according to claim 1 , wherein after the ultrafine fiber portion is impregnated with or coated with the moisture permeable substance, the porous sheet and the ultrafine fiber portion are thermally bonded to each other. 6 . The partition member for total heat exchange element according to claim 1 , wherein the moisture permeable substance includes a quaternary ammonium group. 7 . The partition member for total heat exchange element according to claim 4 , wherein the heat-fusing component is a polymer having a hydrophilic group. 8 . The partition member for total heat exchange element according to claim 1 , wherein the porous sheet is structured of sheath-core bicomponent fibers including a low-melting point component capable of thermally fusing in its outer layer and a high-melting point component in its inner layer. 9 . A total heat exchange element using the partition member for total heat exchange element according to claim 1 . 10 . A total heat exchange type ventilation device using the total heat exchange element according to claim 9 .
