Abstract: The present invention relates to a process and equipment (1) for creating prints on non-woven-fabric and, particularly, relates to a process and to equipment (1) which allows the creation of color prints on non-woven fabrics at high speed while at the same time maintaining optimal print quality on wet or dry product, either in-line with production or off-line. The NWF may be printed over only a small percentage with respect to its surface (2-3%) up to a coverage of 100% of its surface, depending on the use of the NWF itself, i.e.: personal hygiene, domestic hygiene, matting, non-woven fabric for clothing, table-cloths, handkerchiefs, curtains (furnishings), bags, containers for items.
Abstract: Separation media, separation modules and methods are provided for separating water from a water and hydrocarbon emulsion and include a fibrous nonwoven coalescence layer for receiving the water and hydrocarbon emulsion and coalescing the water present therein as a discontinuous phase to achieve coalesced water droplets having a size of 1 mm or greater, and a fibrous nonwoven drop retention layer downstream of the coalescence layer having a high BET surface area of at least 90 m2/g or greater sufficient to retain the size of the coalesced water droplets to allow separation thereof from the hydrocarbon.

Abstract: A coalescence media for separation of water-hydrocarbon emulsions comprises an emulsion-contacting sheet formed of: (a) at least one component of the group consisting of natural fibers, cellulose fibers, natural-based fibers, and cellulose-based fibers, at least one component of the group consisting of high-surface-area fibrillated fibers, surface-area-enhancing synthetic material, glass microfibers, and nanoceramic functionalized fibers; and (c) at least one component of the group consisting of a dry strength additive, and a wet strength additive, wherein the fibrous components of the media constitute at least about 70% of the media. In preferred embodiments, the coalescence media comprises kraft fibers, fibrillated lyocell fibers, glass microfibers or nanoceramic functionalized fibers, a wet strength additive, and a dry strength additive. Preferably, the coalescence media is formed as a single, self- supporting layer from a wet-laid process using a homogenously distributed, wet-laid furnish.
