Abstract: An apparatus for the preparation of bonding fibers, especially for the production of nonwovens by a wet-lay process, wherein a polymer dispersion, containing an anionic or nonionic dispersant, and an aqueous solution, containing a dissolved cationic precipitant, are combined to cause fiber formation from precipitated polymer particles, which apparatus includes a feed funnel spaced above the bottom of a homogenization vessel with both a nozzle for introducing the polymer dispersion and a metering device for the precipitant, which are so arranged and aimed into the funnel that in co-operation with a stirrer a vortex is produced in a column of liquid in the feed funnel, and fibers are formed and broken up while passing through a turbulence chamber, located at the bottom of the funnel, and a gap into a homogenization chamber.

Abstract: A process for the repeatable production of shaped particles of various geometries from polymer dispersions, melts or solutions, wherein first particles are expelled by means of a rotating disk and are introduced while still liquid, in a radially outward direction, into a liquid precipitant or fixant film and the particles are thereby coagulated or fixed and also given an additional structure and are transported away from the point of introduction.

Abstract: A process for consolidating the surface of a granular adsorbent, wherein a water-containing adsorbent, which has taken up 25-70% by weight of the maximum possible amount of water, is heated to a temperature at which the water taken up evaporates, and is at the same time treated with an aqueous dispersion of a self-crosslinking copolymer, and the adsorbent thus coated is heated to a temperature at which the copolymer crosslinks. The coated adsorbent has virtually the same adsorption and desorption properties as the untreated adsorbent, but in contrast exhibits substantially improved abrasion resistance.
