Absorbent composites suitable for a wide variety of uses (e.g., sorbent drapes, sorbent patches around a fenestration area, tray liners for surgical tools, incontinence pads and liners, other liners, etc.) are provided. The composite includes an absorbent nonwoven. The absorbent nonwoven may comprise a hydroentangled spunbond web. The composite also may comprise a liquid-impermeable film. One or more absorbent nonwovens of a composite may additionally comprise a three-dimensional pattern, for example, a three-dimensional pattern that has been imaged using hydroentanglement. Optionally, any one or more layers of the composites may comprise an antimicrobial additive.

The invention relates to a process for the production of cloth products impregnated with an impregnating agent, wherein the process comprises reinforcing and/or bonding fibres and/or nonwovens by means of hydroentanglement, wherein after the hydroentanglement a concentrate of an impregnating agent is applied to the fibres and/or nonwovens which are interconnected and/or reinforced and are still impregnated with water, wherein the concentrate, together with water with which the interconnected and/or reinforced fibres and/or nonwovens are impregnated after hydroentanglement, forms the impregnating agent with which the impregnated cloth products are impregnated.

Wipes for preventing chlorine depletion suitable for commercial applications (e.g., industrial and consumer disinfectant wipes) are provided. The wipe includes at least one nonwoven layer, at least one pulp layer, and a nonionic modified siloxane additive. The at least one nonwoven layer and the at least one pulp layer may be hydroentangled to form a hydroentangled nonwoven fabric having a first surface and a second surface. Additionally, the nonionic modified siloxane additive may be disposed on at least one of the first surface or the second surface.

A method for producing a wet-laid non-woven fabric web includes: providing a first suspension with natural pulp fibers in a first tank, providing a second suspension with regenerated cellulose fibers in a second tank, combining the first suspension and the second suspension to create a mixture, feeding the mixture to a headbox and dewatering the mixture in the forming section of a machine for producing the wet-laid non-woven fabric web. The second suspension with the regenerated cellulose fibers is conveyed by a volumetric pump, in particular by an eccentric screw pump, from the second tank into the volume flow of the first suspension. Wherein over the entire conveying path between the second tank and the headbox, the second suspension is not conducted through any mixing chest having a stirrer. Furthermore, a corresponding system for carrying out the method is taught.
