Who invented wrinkle free cotton? Ruth Benerito. The invention of wrinkle-resistant cotton fabric by Benerito, a physical chemist, is credited with saving the cotton industry. Synthetic fibers, such as nylon and polyester, were invented in the 1930s and 1940s.
When did Ruth Benerito create wrinkle free cotton? In 1958 Benerito began to research how to treat cotton fabric with chemicals so that it would wrinkle less. She invented a treatment that kept cotton from creasing when it was wet or dry. Her discovery helped the cotton industry stay in business.
Is there wrinkle free cotton? While natural fibers aren’t usually wrinkle-resistant, cotton can be specially treated to prevent wrinkles and save you time and effort during the clean and care process. Wrinkle-resistant cotton is especially used for men’s and women’s dress shirts and cotton sheets.
How is wrinkle free cotton made? Wrinkle resistant treatments have been used since 1929, when cotton fabrics were treated with a solution of urea and formaldehyde. The chemical treatment stiffened the fabric, thus making it wrinkle-resistant.
