Abstract:
The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.
Abstract:
A non-continuously laminated structure of thermoplastic films comprises thermoplastic films with differing material compositions and differing functional benefits. In particular, one or more embodiments comprise thermoplastic films that are co-extruded separately and then combined together by a post-extrusion bonding process. The differing composition of the various films of the non-continuously laminated structure of thermoplastic films and the post-extrusion bonding process, provide the structures with the functional benefits of the individual films.
Abstract:
Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a “bag-in-a-bag” type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.
Abstract:
The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers to retain an insulating fill material. Perforations along the seams between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.

Abstract:
A heat-seal device generally includes a heat source, a thermal conductor, which encapsulates at least a portion of the heat source and is capable of transferring heat from the heat source, and a thermal insulator, which substantially surrounds the thermal conductor but leaves a portion thereof exposed, the exposed portion of the thermal conductor providing a heat-seal contact surface, which is adapted to be brought into sliding contact with a material to be sealed.

Abstract:
A method for cutting along a cutting line of a laminate, including a first and a second textile layer surrounding an intermediate layer of a porous elastic material. The laminate is pressed together in a local nip between an ultrasound emitting element and a counteracting element, and the laminate is moved in the cutting line through and past the nip during ultrasound cutting of the laminate simultaneous with ultrasound welding of the first and the second surface layers to each other in order to form a smooth, rounded, continuous edge joint between the surface layers at a free edge of the laminate.
Abstract:
An extensible laminar material 100 includes an extensible layer 106 coupled to at least one laminar layer 102, 104. The extension of the extensible layer 106 starting from a non-extended condition determines the extension of the laminar layer(s) 102, 104 while the return of the extensible layer 106 toward the non-extended condition determines the pulling of the laminar layer(s) 102, 104 into a wrinkled condition. The extensible layer 106 and at least one laminar layer 102, 104 are connected by welding to avoid their detachment. The extensible layer 106 is anchored to at least one laminar layer 102, 104 by lines of spread adhesive 108, 108′. The welded connection is absent in correspondence of the lines of spread adhesive 108, 108′. Preferably, the material is in the form of a web 100 extensible transversally to the longitudinal extension of the web with the lines of spread adhesive 108, 108′ extending along the sides of the web.
Abstract:
Bedding products may utilize unique microporous films imparting bidirectional, micro particle and fluid penetration barrier properties, which may or may not contain active ingredient, while maintaining exceptional air permeability. A thin, microporous film with a unique sponge like cellular structure may prevent the migration of dust mites, dust mite feces, other micro particle allergens, pathogens and biological organisms from the interstices of the product to the sleep surface of the product, adversely affecting user health and comfort. Active ingredients such as anti microbial agents, metal oxides, and other materials may be used within the high capacity microporous structure of the film, and may provide customizable functionalities while maintaining barrier performance and superior air permeability. The micro structured film can be applied as a coating or a laminate to mattress or pillow ticking, a foam mattress construction, a comforter, duvet, mattress pad and/or other components of bedding products.
