Abstract
This invention involves an application of the so-called 'riblet' effect to the fabrics used on machines in the papermaking industry. The 'riblet' effect itself is a reduction in the measured frictional drag on a surface that is moving relative to a fluid when microscopic grooves are machined on a surface in a direction parallel to that of the motion. Here, this finding is applied to the fibers, filaments, and monofilaments used in the weaving of papermakers fabrics, and to the fibers used to form batts which are needled into the structure of base fabrics, as a way to enhance their water-removing abilities.
