MOISTURE TRANSPIRATION COMPOSITE AND PRODUCTS THEREFROM

摘要

A formed hydrophilic urethane polymer foam composite HF with particles 3 up to 0.1% by weight of superabsorbent polymer and selectively other additives to enable collected moisture to move from an area of high humidity to an area of lower humidity, having a urethane polymer foam layer formed into a sized and shaped matrix, having interconnected strands 4 and filaments 1 of the urethane polymer and sized and shaped interstitial gaps and spaces 2, said particles 3 of superabsorbent polymer dispersed in, on and through said interconnected strands and filaments in spaced relationship and the sized and shaped interstitial air gaps 2 to provide improved capillarity in the formed foam matrix enhance transpiration and also multi-layered embodiments including at least one of said formed foam composites 5 to transpire collected moisture and enable evaporation of the transpired moisture.
