摘要： Foamed articles including a foamed thermoplastic elastomeric material, methods of making the articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating the articles are provided. One exemplary method for making a foamed article comprises placing an article comprising a foamable fibrous element and carbon dioxide in a vessel, the foamable fibrous element comprising a plurality of filaments, fibers, and/or yarns, wherein each member of the plurality comprises a foamable material; maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material; optionally exposing the infused article to a second temperature and second pressure; and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

摘要： A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.

摘要： A network of microfibers are fabricated with a core-shell construction from sustainable materials, where the core includes a phase-change material, such as coconut oil, and the shell includes a biomass, such as cellulose. The microfibers are made via a wet-wet electrospinning process utilizing a coaxial spinneret with an inner conduit and an outer conduit. The biomass and the phase-change material are coaxially extruded into a coagulation bath including a mixture of ethanol and water. The collected microfibers exhibit a beaded structure of PCM aggregates and biomass connecting regions between the aggregates and are effective to aid in the thermoregulation of the immediate environment surrounding the network. The microfibers are suitable for use in a variety of sustainable products such as wearable thermoregulating textiles, wall/ceiling panels, insulation, packaging material, and more.

摘要： A dermal dressing is provided that comprises a foam layer and an adhesive layer applied directly thereon. A textile fabric is arranged on a side of the foam layer facing away from the adhesive layer, and the textile fabric comprises a vertically-lapped nonwoven. A method for producing the dermal dressing of the first aspect is also provided. The method comprises: providing the foam layer; applying the adhesive layer to the foam layer; applying the textile fabric to a side of the foam layer facing away from the adhesive layer; and bonding the foam layer and the textile fabric. The dermal dressing has optimal properties for its use in preventing pressure ulcers.
