Abstract: A wall covering comprising a planar substrate having a front and a back facing opposite the front and an adhesive layer that covers the back of the substrate. The adhesive layer includes a separate polymer layer, formed by a polyvinyl alcohol polymer. Wall covering for example in the form of a pre-pasted paper is readily reactivated when wet, and exhibits no blocking, while having properties of sliding, adhesion, and stripability.

Abstract: Fibrous filtration media and methods of making and using the same are provided whereby the media includes a wet-laid nonwoven fibrous web having from about 20 wt. % to about 80 wt. %, based on total weight of fibrous web, of bicomponent staple fibers, and from about 10 wt. % to about 50 wt. %, based on total weight of the fibrous web, of fibrillated lyocell staple fibers. The fibrous web exhibits a wet burst strength of greater than 3 bar, for example between about 3 bar to about 6 bar and is especially suitable for use in filtering process fluids (e.g., water) associated with wire electron discharge machining (WEDM).
