Abstract
The present invention relates to liquid entrapping devices (e.g., absorbent non-woven fibrous mats) and to a process for preparing such devices. More particularly, the present invention relates to mechanically strong absorbent materials made from such liquid entrapping devices (e.g., non-woven fibrous mats) and to a method for preparing same. In one embodiment, a liquid entrapping device of the present invention comprises at least one hydrophilic elastomeric fibrous component (HEFC) and at least one wetting agent component. In another embodiment, a liquid entrapping device of the present invention comprise at least one hydrophilic elastomeric fibrous component (HEFC), at least one absorbent component, and at least one wetting agent component. In one instance, the wetting agent component of the present invention is contained on and/or within the fibers and/or nanofibers that form the liquid entrapping device (e.g., a non-woven fibrous mat) of the present invention.
