Jacquard loom
Karasz ventured into a number of unusual areas connected with textile design and production. She was known as a pioneer of modern textile designs requiring the use of the Jacquard loom, and she became one of the few women to design textiles for planes and cars. In the late 1920s, Dupont-Rayon Company hired her to help improve the texture and feel of rayon and generally raise the production standards for this then-new material. Karasz experimented with many new materials and manufacturing processes throughout her career. Her work for F. Schumacher and Company in 1929 was used in a Fokker airplane.
