Publication number: 20130108831Abstract: Nonwoven electret fibrous webs including randomly oriented discrete fibers comprising electret fibers, the webs including a multiplicity of non-hollow projections extending from a major surface of the nonwoven electret fibrous web, and a multiplicity of substantially planar land areas formed between each adjoining projection in a plane defined by and substantially parallel with the major surface. In some exemplary embodiments, the randomly oriented discrete fibers include multi-component fibers having at least a first region having a first melting temperature and a second region having a second melting temperature, wherein the first melting temperature is less than the second melting temperature. At least a portion of the oriented discrete fibers are bonded together at a plurality of intersection points with the first region of the multi-component fibers. In certain embodiments, the patterned air-laid nonwoven electret fibrous webs include particulates.Type: ApplicationFiled: July 6, 2011Publication date: May 2, 2013Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Tien T.

Publication number: 20130037481Abstract: Nonwoven fibrous webs including a multiplicity of discrete fibers, a population of sub-micrometer fibers having a population median diameter less than one micrometer adjoining the discrete fibers, and a multiplicity of chemically active particulates secured to the nonwoven fibrous web. In some embodiments, more than 0% and less than 10% wt. of the nonwoven fibrous web is made of discrete fibers that are thermoplastic polymeric fibers, and which optionally at least partially melt and coalesce to secure the discrete polymeric fibers to each other. In certain embodiments, at least some of the particulates are bonded to the thermoplastic polymeric fibers. In other embodiments, at least some of the particulates are secured within interstices of the fibrous web, without substantial bonding to the discrete fibers. Methods of making and using such nonwoven fibrous webs are also described.Type: ApplicationFiled: April 14, 2011Publication date: February 14, 2013Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Lahoussaine Lalouch, Gerry A.

Patent number: 6746974Abstract: The present invention provides a web material useful as a tack pad comprising a non-woven cross-laid web which is needle-tacked and at least one of chemically or thermally-bonded and at least one major surface of which is impregnated with a tackifier. The invention also provides a dispenser that will accept a stack of tack pads. The dispenser is shaped to contain a stack of tack pads in position over an outlet opening in the bottom of the dispenser and to permit one access to one edge of the bottom pad of the stack. The edge is located inside the dispenser and the dispenser comprises an at least partially open front and a door mounted on the dispenser. The door may be pivoted between an open position and a closed position over the front. The door has turned-back side edges to fit around the dispenser to prevent dust from entering the dispenser. The bottom pad can be pulled downwardly away from the stack through the outlet opening.Type: GrantFiled: July 31, 2000Date of Patent: June 8, 2004Assignee: 3M Innovative Properties CompanyInventors: Philippe Reiterer, Jean Le Normand, Roy Parmentier, Christopher J.
