  • Patent number: 11549199
    Abstract: A fabric delivers active ingredients to a surface when the fabric includes a moist-vapor porous combination of fabric materials, and the fabric comprises at least 0.5% by total weight of at least one layer of the fabric of a superabsorbent polymer fiber. The superabsorbent polymer fiber contains an absorbed aqueous reservoir of an aqueous solution carrying the active ingredients. The superabsorbent fiber has a coating on its surface of an aqueous penetrable layer through which a liquid in the absorbed aqueous reservoir can migrate or flow, carrying the active ingredients onto an exposed surface of the superabsorbent polymer fiber, so that the active ingredients on the surface of the superabsorbent polymer can react or interact with an environment in contact with the active ingredients on the superabsorbent polymer fiber surface.

  • Patent number: 9901128
    Abstract: An apparel or material which may be placed anywhere or worn about the neck or other parts of the body of a human. The apparel/material has a structure that, when repositioned from about the wearer, will retain a position about a mouth and nose of the human, as by elasticity or taughtness of a wrapping about the face. The apparel is sufficiently porous as to allow a human to breath comfortably through the fabric when placed over the mouth and nose of the human. The fabric has as a coating is created with on at least the outer surface and through at least 25% of the thickness of the fabric a moisture-sensitive antimicrobial composition, wherein the antimicrobial moisture-sensitive composition comprises an antimicrobially active compound and a carrier, the carrier by hydrophilic and able to absorb sufficient moisture from exhaled breath from the human as to maintain a wet surface on the carrier to which viral particles will adhere more strongly than to a dry surface of the same carrier.

  • Publication number: 20170001425
    Abstract: Specific composite materials described herein are based on the discovery that certain selections of materials and manufacturing conditions and processes provide unexpectedly improved self-supporting thin-film composite materials. It has been discovered that certain combinations of backing materials, shrink film materials, and manufacturing conditions provide improved composites having highly controllable, readily repeatable, and stable arc shaped cross-web curled structures. In general, the composite materials described herein comprise a dimensionally alterable film such as a polyester shrink film having a first surface and a second surface, and a polyester backing material having a first surface and a second surface, wherein the second surface of the backing material is laminated to the first surface of the dimensionally alterable film.

  • Publication number: 20120255648
    Abstract: A wood chipper includes an in-feed spout with an input end and an opposing feeding end, a motor-turned chipper blade to receive logs at the feeding end, and one or a pair of independently-operable, hydraulic arms movable between a first position external to the in-feed spout and a second position internal to the in-feed spout through a gap in the in-feed spout. When inserted, the arms clear jammed logs laying anywhere across the width of the in-feed spout. The arms are operated by hydraulic rams secured to a bracket, preferably attached to a cover over a portion of the in-feed spout near the chipper blade and in proximity to the gap in the in-feed spout.
