A wound dressing material comprises first and second wound-contact scrims, and an antimicrobial layer disposed therebetween. The wound-contact scrims comprise water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units. The wound dressing material may be contacted with an exposed surface of a wound. A method of making the wound dressing material is also disclosed.

An article () has a polyester film backing () and a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (). Another article includes a polyester backing (), a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (), and a phenolic layer () disposed on the primer layer () on a surface opposite the polyester backing (). The phenolic layer () can include abrasive particles (). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing () and a phenolic layer () on the polyester backing ().

Articles including polyester backing and primer layer and related methods

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Adhesive articles permitting damage free removal

A powder deagglomerator includes a vertical flow chamber, a powder inlet tube, and an ultrasonic horn vibrationally coupled to an ultrasonic transducer. The vertical flow chamber includes an outer wall, powder outlet port, and a mounting port sealably engaging an ultrasonic horn. The powder inlet tube extends through the outer wall and is aligned to dispense agglomerated powder in a gaseous stream downward onto a distal end of the ultrasonic horn. A method of using the powder deagglomerator to deagglomerate a powder is also disclosed.

A method of preparing an anisotropic polymer film using an electric field generator. The method of preparing an electric field generator comprising supplying an electric field across an electric field application zone, where the electric field is generated by a first electrode having a first charge and a second electrode having a charge opposite of the first, passing a polymer film that optionally includes dispersed particles through the electric field application zone, where the polymer film contacts the first electrode to induce orientation, and freezing the polymer film to lock the orientation before the polymer film exits the electric field application zone.

A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.
