Advansa has expanded its ADVA shortcut product portfolio to a new microfiber for wetlaid processing: with 0.2 dtex and a mean diameter of 4.3 µm, the material is designed for filtration and other technical applications. Available in cut length of 3 mm or longer, the material disperses homogenously in water. Filtration media with a small and narrow pore size distribution can be obtained, as the fiber has also a very narrow diameter distribution: the variation coefficient is clearly lower than 10%.

The new microfiber is a completion of Advansa’s product portfolio in the direction of finer fiber. Further microfiber at 0.3 and 0.5 dtex, as well as regular fiber with 1.7, 3.3, 6.7 and 17.0 dtex, are available and well established options for filtration media developers to control filter key parameters like efficiency, pressure drop, mechanical strength, thermal stability and many others. Most of those fibers meet the requirements for food contact applications according to EU, BfR and FDA regulations. The options are completed by various core-sheath-binder fibers with polyester core and co-polyester or polyolefine sheath with melting ranges around 110, 130, 160 and 180°C. Thus, a wide range of high quality wetlaid filtration media for many purposes and process routes can be engineered using ADVA shortcut as base material.
