Abstract
The invention relates to an article, in particular a glove, a condom, or the like, which is comprised of a flexible rubber and/or plastic, is embodied having at least one section of the surface intended contact or rest against human skin, which article is provided with a slip coating in a section of the surface. This slip coating is comprised of a polymeric material and at least in sections, has repeating shape deviations of the surface that are recessed in relation to a raised, net-like structure. The ratio of the average spacings between the shape deviations to their depth in relation to the raised, net-like structure is between 500:1 and 5:1 and the average roughness depth is between 0.5 and 100 μm, preferably between 1 and 40 μm.
Claims30
A process for producing a flexible article, comprising:
- providing a dipping form;
- dip-coating a carrier layer material comprising at least one of plastic and rubber on the dipping form to form a carrier layer, the carrier layer including a plurality of surface sections;
- dip-coating a slip coating material on at least one of the plurality of surface sections to form a slip coating, the slip coating including a partial area, the partial area of the slip coating including a raised net-like structure and a plurality of recessed shape deviations;
- immediately drying the slip coating with hot air for between about 10 seconds and 600 seconds;
- applying hot water to reduce the water content of the slip coating by approximately 40% to approximately 70%;
- and
- draining the flexible article.
