History of Sanforization


Sanforizing is a method that was produced in the 30s to prevent denim from shrinking. Having spent his youth wrangling alligators in Florida, learning the Seminole language and working in the engineer corps for the Spanish-American War, the process of sanforizing was invented by Sanford Lockwood Cluett (1874–1968) in 1930.
Developed in the late 1920s by the American chemist Sanford Cluett and patented by Sanforize Co. in 1928, the process was reportedly first used by Erwin Mills in 1936 to make denim for overalls marketed under JC Penney's Big Mac label. Lee jeans were made from Sanforized fabric soon afterwards, but Levi's jeans remained shrink-to-fit for another three decades until the 1960s. Sanforization is known as "Controlled Compressive Shrinkage Process" in textile industry and it is the most popular method for pre-shrinking fabrics.
