It relates to a beaded nonwoven membrane comprising polymeric nanofibers and at least one active agent, wherein the active agent has a water solubility equal to or lower than 33 mg/mL. It also relates to a process for the preparation of the beaded nonwoven membrane, and to its use in medical, and veterinary applications.

The invention relates to an installation and a method for selectively producing a single- or multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction.

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.

A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.
