As man-made fibres emerged, Traverso established himself as a consultant to advise chemical companies on how to give a more luxurious feel to nylon, acetate, viscose, polyester and acrylic — many of which were in essence plastic. His first major consulting work began in 1957, with British Nylon Spinners, which later became ICI Fibres, and this continued for more than 20 years. Through this connection he also provided advice to DuPont of Canada, and then to various yarn-spinners and processors, including Courtauld’s Yarns. He retired in 2003, but delighted in remaining in contact with friends and colleagues from around the world.
