Abstract:
A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.
Abstract:
The present disclosure generally relates to air filters expandable from a collapsed arrangement to an expanded, end-use arrangement and to methods of making, using, and installing such air filters. Some embodiments relate to an air filter having an expanded state and a collapsed state. The air filter includes a filter media assembly including (1) filter media including a plurality of pleats, (2) first and second opposing sides, and (3) first and second opposing ends. The air filter also includes a shape retention structure capable of being connected to at least a portion of the filter media assembly and capable of retention the filter media assembly in the expanded state. A spacing distance between adjacent pleats in the filter media is greater in the expanded state of the air filter than in the collapsed state of the air filter. In some embodiments, the air filter is an HVAC air filter.

Abstract:
Polymeric foamed compositions, foam padded materials that include such polymeric foamed compositions, and packaging articles (e.g., envelopes) that include such foam padded materials, wherein the foamed composition includes: a polymeric component including a copolymer including divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; wherein the composition is in the form of an at least partially water-soluble foam.
Abstract:
The present application relates to compostable articles and compositions including at least one biodegradable polymer and a hydrophobic agent. In some embodiments, the compostable articles and compositions include a second biodegradable polymer, different from the first biodegradable polymer. In some embodiments, the first biodegradable polymer is selected from the group consisting of poly(ethylene succinate) (PES), poly(trimethylene succinate) (PTS), poly(butylene succinate) (PBS), poly(butylene succinate co-butylene adipate) (PBSA), poly (butylene adipate co-terephthalate) (PBAT), poly(tetramethylene adipate-co-terephthalate) (PTAT), and thermoplastic starch. In some embodiments, the presently described articles include packaging.
Abstract:
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.
