Today we celebrate the birthday of Ruth Rogan Benerito (born 12 Jan 1916), the American chemist and inventor whose innovations in fabric technology have saved the world many many hours slogging away in front of the ironing board. Dr Benerito was the inventor of wash and wear cotton fabric.
As if this wasn’t enough of a gift to the world, Benerito also came up with numerous other innovations – in total she has been granted no less than 55 patents related to textile technology. Thanks to her we now have fabrics that are quicker drying, crease and stain resistant, comfortable and better able to retard flames. She also developed a cotton textile cleaning technique (adopted widely in the Japanese textile industry) using radiofrequency cold plasmas. This method replaces the commonly used technique of pre-treating cotton with sodium hydroxide, as such greatly reducing the environmental impact. Many of her innovations also found application in the wood and paper industries.
The key to the wrinkle-resistant fabric was a process called molecular cross-linking. She discovered that the long chain-like cellulose molecules that make up cotton fibre can be chemically treated so they are bound (cross-linked) together – a process that strengthens the hydrogen bonds between the cellulose molecules, leading to the advantageous result that the cotton becomes less prone to wrinkling.
On an almost completely unrelated note, far removed from her important and ground-breaking work in textiles, Benerito also developed a novel technique to administer fat intravenously to patients too sick or wounded to eat. This innovation has helped save the lives of thousands of people by maintaining their nutrition levels during severe illness.
From clothing to nutrition, these are some truly useful innovations indeed!
