Abstract:
A framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The framed pleated air filter does not include any support member on the downstream face of the pleated air filter media.
Abstract:
The invention provides a method of making a flexible and self-supporting insulating end cone liner comprising resilient and compressible non-intumescent material molded into a single, continuous piece having a three dimensional cone shape, with the insulating material comprising inorganic fibers and a binder, as well as a method of making a pollution control device that includes such an end cone liner.
Abstract:
Containers (100), for example boxes, envelopes, mailers, and the like containing one or more deployable cushioning sheets (1500) are disclosed. The deployable cushioning sheets (1500) are connected to at least one wall of the containers (100) and can be deployed to be partially outside of the container for cushioning, for example by wrapping, an object (1600) to be packaged. The deployable cushioning sheets (1500) can contain, for example, paper, cardboard, foam, bubble film, or the like, or they can contain combinations of different types of materials. The containers (100) are useful in methods of packaging, storing, and shipping, among other uses.
Abstract:
An article (100) has a polyester film backing (110) and a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (110). Another article includes a polyester backing (110), a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (110), and a phenolic layer (140) disposed on the primer layer (120) on a surface opposite the polyester backing (110). The phenolic layer (120) can include abrasive particles (160). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing (110) and a phenolic layer (120) on the polyester backing (110).
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 polyethylene succinate) (PES), poly(trimethylene succinate) (PTS), poly(butylene succinate) (PBS), poly(butylene succinate co-butylene adipate) (PBS A), 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:
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:
A scouring article including a monolithic nonwoven pad with a semi-densified fibrous layer that is integral to the monolithic nonwoven pad and that provides a major surface of the monolithic nonwoven pad, and methods of making and using.
Abstract:
A nestable framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips and downstream pleat valleys, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The filter includes a frame with sidewalls that are angled so that the framed pleated air filter is nestable.
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.
