    • The present invention provides a method of making a nonwoven web, the method including the steps of providing plurality of fibers and subjecting the fibers to a pneumatic attenuation force which imparts a velocity to the fibers, reducing the velocity of the fibers in a diffusion chamber which is formed substantially between opposed diverging sidewalls, subjecting the fibers to an applied electrostatic charge, and thereafter collecting the fibers into a web on a moving forming surface. The invention also provides an apparatus for forming nonwoven webs, the apparatus comprising a source of fibers, a fiber attenuation chamber, a diffusion chamber formed substantially between opposed diverging sidewalls, the diffusion chamber located below the fiber attenuation chamber, and a forming surface for collecting the fibers as a nonwoven web.

    • A process is described for the production of a multicoat lacquer finish by application of a base coat layer of an aqueous coating agent to a substrate and subsequent application of a layer of a clear coat containing an organic solvent, that leads to coatings with excellent hardness and gloss. For this purpose, for the production of the base coat layer an aqueous coating agent is applied that contains, in addition to water, one or more pigments, and optionally one or more organic solvents, neutralizing agents and customary lacquer additives, as binder a combination of:I) 99.5 to 85 wt % of one or more aqueous, physically drying polyurethane binders andII) 0.5 to 15 wt % of one or more polyisocyanates, liquid at room temperature or liquefied by organic solvents, with more than one free isocyanate groupswherein the wt % of components I) and II) both relate to their solids content and add up to 100 wt % and wherein component II) is added to the coating agent shortly before its application.
