Sanforization

Sanforization is a treatment for fabrics to reduce shrinkage from washing. The process was patented by Sanford Lockwood Cluett (1874–1968) in 1930. It works by stretching, shrinking, and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing.

The original patent mentioned "goods of cotton, linen, woolen, silk, rayon, and combinations thereof".
