A flocked surface tribo-electric charge generator includes first and second contact surface electrodes; first and second flock fiber support layers a first flock fiber material flocked onto the first flock fiber support layer; a tribo-electrically second different flock fiber material flocked onto the second flock fiber support layer. A tribo-electric charge is generated by intermittent intermeshing/separation of the tribo-electrically diverse flock fiber materials of the first and second flock fiber support layers.

Flocked surface triboelectric charge generator and method of manufacturing

Swabs, materials, and methods of making same, include randomly arranged sea-island bicomponent fibers. According to certain embodiments, swabs and methods of using such swabs are provided so as to collect and release a biological sample comprising a flock fiber tipped applicator wherein the flock fibers are sea-island bicomponent fibers attached to an end portion of the applicator with an adhesive selected from the group consisting of a photocurable acrylic adhesive and a polyurethane adhesive, the bicomponent fibers being structurally stable in water and the sea component of the bicomponent flock fibers being intact.

Collection device and material

Swabs, materials and methods of making the same include randomly arranged sea-island bicomponent fibers which have randomly splayed terminal ends. According to certain embodiments, swabs are provide which include an applicator, and sea-island bicomponent fibers attached to the applicator, wherein at least about 70% of the fibers comprise randomly splayed terminal ends of the islands of said bicomponent fibers along a length of about 45% or less from said ends, and wherein the bicomponent fibers comprise 10-3000 island parts per fiber.

A flocked helmet cover pad (FHCP) attachable add-on to a helmet cover includes a central hub and multiple appendages attached to the central hub. The appendages are shaped and arranged to provide additional impact energy absorption properties for a helmet.

Embodiments of fiber surface finish enhanced flocked surface impact force absorbing structure include a plurality of flock fibers disposed on a substrate, a surface coating applied to the plurality of flock fibers, and in another embodiment, a divider fabric bonded to the tops of flock fibers.

Fiber surface finish enhanced flocked impact force absorbing structure and manufacturing

A panel for absorbing mechanical impact energy includes a substrate and a multiplicity of fibers attached, by one of their ends, to the substrate with their other ends extending away from the substrate. The panel may include a thin, porous covering layer that overlies the free ends of the fibers. The porosity of the cover and the fiber density of the fibers may allow for breathability of the panel. The panels may be flexible and may be used in body protection devices such as helmets, body armor as well as in other environments. Panels may be configured in a variety of energy absorbing arrangements for differing applications.

Swabs, materials and methods of making the same include randomly arranged sea-island bicomponent fibers which have randomly splayed terminal ends. According to certain embodiments, swabs and methods of using such swabs are provided so as to collect and release a biological sample comprising a liquid, wherein the swab includes an applicator and sea-island bicomponent fibers, and wherein at least about 50% of the fibers possess randomly splayed terminal ends of the islands of the bicomponent fibers along a length of about 10% or less from such ends.

A flexible, fibrous energy managing composite panel includes multiple flocked energy absorbing material (FEAM) layers separated by dividers. The FEAM layers can be single side or double side and can be fabricated from monofilament fibers having different properties (e.g., length and denier) flocked onto various substrates. The dividers can include sheets, fabrics, films, foam, spacer fabrics to separate the flock fibers in adjacent layers. The composite panels can be processed for breathability and flexibility. Other embodiments include piezoelectric FEAM layers and dividers for electronic sensing applications, and application of composite panels to body armor and the outer shells of helmets.
