A nonwoven material formed of bicomponent fibers may be used as a cosmetic cushion to hold cosmetic compositions, such as liquid foundation, in a housing for consumer use with an applicator. The use of bicomponent fibers may allow for the utilization of various natural or synthetic materials for the core and shell which may be adjusted for greatest compatibility with cosmetic compositions. Bicomponent fibers forming nonwoven materials may be a polyethylene terephthalate (PET) core/polyethylene (PE) shell composition. This PET/PE composition may allow for maximum stability and chemical resistance in combination with aggressive chemical ingredients. Cosmetic cushions using these nonwoven materials may feel sensationally pleasing to the consumer and perform with the best quality throughout the lifetime of the product. The cosmetic cushion also may look aesthetically pleasing when filled or saturated with product.

Stents are disclosed herein. In some embodiments stents within the scope of this disclosure may comprise a first flared end and second flared end. In some embodiments, a profile of each of the first flared end and the second flared end may circumscribe a portion of separate elliptical arcs. In some embodiments, the stents are formed from braided or woven wires having a constant pitch along a middle region and continuously varying pitches along the first flared end and the second flared end. Methods of manufacturing stents are disclosed herein. Methods of using stents are also disclosed herein.

Yarns incorporating filaments of shape memory materials are described herein that enable the creation of fabrics, garments, and other materials with tunable force absorption or exertion capabilities, as well as creating complex shapes and structures upon actuation. Systems and methods described herein enable selective buckling, recruitment, compression, and other desirable phenomena by actuating fibers in knitted patterns, whether used as isolated filaments or in twisted yarns.

An illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.

Embodiments of the disclosure provide structures for sensing, activation, and signal networking in a composite textile. According to one embodiment, a composite textile can comprise an activation layer of a reactive yarn knit into a fabric. The reactive yarn can have at least one physical property that changes in response to a stimulus. A signaling layer of a first conductive yarn can be knit into the fabric with the activation layer. The first conductive yarn provides the stimulus to the reactive yarn. A sensing layer comprising second conductive yarn can be knit into the fabric with the activation layer and signaling layer. The second conductive yarn can provide a feedback signal corresponding to the stimulus provided by the first conductive yarn of the signaling layer.

An enzyme responsive shape memory polymer formed from a glassy, cross-linked shape memory polymer that incorporates ester bonds that are responsive to the present of an enzyme. PCL-based polyurethanes (featuring simple alternation of PCL diol and lysine-based diisocyanate) are degradable by Amano lipase PS. A non-degradable thermoplastic elastomer may be dual electrospun with a polycaprolactone based TPU with the fixing phase compressed so that the composite is ready for enzymatically triggered contraction. Alternatively, the elastomer may be a PCL copolymer-based polyurethane amorphous elastomer that is both degradable and elastomeric and put into compression so that upon enzymatic degradation of the elastomeric phase the scaffold expands.

The present invention is to provide a polyester fabric for airbags famed from a polyester fiber, which can reduce costs, and the polyester fabric for airbags has high restraint performance for receiving the occupant during deployment and maintains the performance at high levels even after aging, while maintaining the mechanical characteristics as a fabric for airbags. The solution to the object is to provide a polyester fabric for airbags having a coating resin on at least one surface characterized in that the polyester fabric has an optimized crimp ratio and has scrub test strokes of 400 or more after aging treatment at 70° C. at 95% RH for 408 hours.

Advances in actuating fabrics could enable a paradigm shift in the field of smart wearables by dynamically fitting themselves to the unique topography of the human body. Active fabrics and fitting mechanisms are described herein that enable garments to conform around surface concavities without requiring high elasticity or a multiplicity of closure devices. Advanced materials and systems innovations (1) enable novel garment manufacturing and application strategies, (2) facilitate topographical fitting (spatial actuation) through garment architectural design, and (3) provide tunable NiTi-based SMA actuation temperatures to enable actuation on the surface of human skin. Such fabrics and garments are usable in a variety of fields including medical compression, technical sportswear, exosuits, space suits and components thereof, or non-garment applications.

An infrared-absorbent resin composition including a tungsten-based infrared-absorbent pigment, copolymerized polyethylene terephthalate, and a polyethylene terephthalate homopolymer, wherein the copolymerized polyethylene terephthalate is crystalline.

An illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.
