Microcapsule fabric for absorption and release
A permeable microcapsule embedded fabric acts as a sorbent that creates mold-able, variable geometry fabrics for static or dynamic use. The fabric is composed of micro encapsulated solvent spheres held together by structural members. The fabric provides an excellent means to absorb and separate gases and/or liquids, particularly to separate carbon dioxide from flue gases.
