Bekaert Carding Solutions, part of Belgium-based advanced materials and coatings supplier NV Bekaert SA, reports its SiroLock® doffer and worker wire provides improved fiber control and web quality, and increased productivity on nonwoven and long-staple roller cards.

SiroLock was developed for use on the breast section of the card's main cylinder, where it can take up to 50-percent more fibers than conventional card wire, thereby reducing recycling of fibers as well as the need for cleaning stops, according to Bekaert. Other advantages include reduced fly, resulting in decreased raw material costs and improved web regularity; and improved blending and the ability to have wider settings between cylinders and workers/doffers than with conventional wire as a result of the higher carding spaces created. The wire also can be used in processing a wide range of fibers including hollow, siliconized, aramid and melt fibers; as well as a wide range of fiber densities.
