These technical textiles are perfect for a large number of applications and markets including the automotive, apparel construction and medical industries. The portfolio includes drylaid, spunlaid and meltblown and wetlaid nonwovens. With high technical ability and a wide range of clients in varied industries, Freudenberg Performance Materials is your ideal partner for nonwoven technologies. Freudenberg Peformance Materials has been called for this expertise by a range of industry types around the world. This includes top firms in the chemical, geotextile, feminine hygiene, and medical industries. Automotive specialists have called upon Freudenberg Performance Materials needle-punched nonwovens for innovative cargo covers. Nonwoven materials from Freudenberg Performance Materials can be found within the energy industry for light diffusion and battery cell technologies. The meltblown process is similar to the spunlaid process. A high velocity hot gas stream impinges on a molten polymer stream as the polymer extrudes from a small capillary in the die. The force of the gas in a turbulent flow rapidly attenuates the filament from a diameter of about 500 micron at the capillary down to filament diameters as small as 1 micron. Compared to the spunlaid process the melt flow index of the polymer is very high, whereas the throughput of the capillary is very low. This low throughput due to very small capillary holes and the high melt flow index are the precondition for manufacturing very thin fibers.
