    Abstract: A method is described for manufacturing a finish formulation for the hydrophobic and/or oleophobic finishing of surfaces, comprising a dispersant incorporating dispersed, activated particles with hydrophobic and/or oleophobic surface groups and a binder, in which particles with hydrophobic and/or oleophobic surface groups are comminuted in the dispersant for activation, and the binder is added before or after activation. The obtained finish formulation clearly improves the physical properties of a transparent finish while maintaining very good hydrophobing/oleophobing. It is suitable for finishing all surfaces, in particular for finishing fibers or textiles of all kinds.

  • Publication number: 20100279081
    Abstract: A system and method for depositing a substance onto a substrate comprises continuously transporting the substrate in a transport direction while traversing a deposition arrangement across the substrate to deposit the substance in a number of swathes. During such movement the positions of the deposition arrangement and the substrate are controlled with respect to one another such that the swathes complement one another to provide substantially uniform coverage of the substrate. As a result of the defined arrangement, improved substrate speeds can be achieved since there is no need for the substrate to stop at each traverse.

The first filter layer exhibits nondecreasing removal efficiency and removes a majority of a challenge aerosol; whereas the second layer exhibits decreasing removal efficiency and has an initial quality factor greater than the first layer. Together, the first and second electret filter layers can provide a filter that exhibits a nondecreasing removal efficiency and a relatively low pressure-drop. The filter can provide nondecreasing removal efficiency and reduced pressure drop even though the second electret filter layer exhibits decreasing removal efficiency in contrast to the desired nondecreasing removal efficiency for the filter as a whole.
