The crushing that occurs in the knot area of a tie is pretty serious, and results in a lot of wrinkling, with regular pressing needed to sort it out. There were several fabrics that were around in the 30s and 40s that claimed to be wrinkle resisting or “non-crush”. Palm Beach fabric was one, and another common one was Priestley’s Nor-East Non-Crush fabric. From what I’ve seen none of them really worked very well. This tie here was put out by Towncraft, J C Penney’s label, and was made by, or of, Cohama fabric, claiming to be wrinkle resistant.
