His innovative work has led to the creation of a unique fiber that possesses both durability and safety features.

Latest Patents

Baumann holds a patent for non-flammable, high-temperature resistant polyimide fibers. These fibers are characterized by their irregularly lobed or serrated cross-sections, a wool-like smooth hand, and high brightness. The fibers are produced through a dry-spinning process conducted in a spinning column. This process involves spinning a 20 to 40% solution of polyimide from spinnerets with circular orifices, which can range from 20 to 800 in number and have diameters from 100 to 300 micrometers. The extrusion speed is maintained between 20 and 100 m/min, while the take-up speed ranges from 100 to 800 m/min. The process also requires a specific amount of spin gas and temperature conditions to ensure the quality of the fibers. The resulting tows, which contain residual solvent, undergo washing, drying, and drawing processes to achieve the desired properties.
