    摘要: A drinking straw that purifies water by forced movement of water through the straw. The straw is composed of: 1) a filter plug made of a fibrous structure, the filter plug having sides, a first end, a second end, and a firmness sufficient to avoid collapse of the fibrous structure under a specified pressure drop; 2) a water purification material integrated in the fibrous structure; and 3) a liquid impervious wrapper covering the sides of the filter plug, the wrapper defining openings at the first and second ends of the filter plug.

    摘要: The present invention relates to a combination for surface treatment of a substrate, e.g. a nonwoven web, used in personal care product applications. The surface treatment combination not only provides adequate fluid handling properties, but also provides a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a botanical extract on skin by an aqueous emulsion mediated dissolution of the agent from a substrate with subsequent transfer and deposition onto the skin. Coatings of the botanical extract on the skin resist removal, thereby preventing damage to the natural skin barrier and providing a protective barrier against chemically- and biochemically-induced skin damage.
