Independent claims are included for: (1) a woven, knitted or nonwoven article comprising the material； and (2) preparing filamentous or fibrous material comprising mixing the liquid oil and the polymerized and/or crosslinked matrix for forming a matrix by polymerization and/or crosslinking at a body temperature； impregnating the material； and removing the mixture.
