Vintage Sanforized Blue Denim Dungarees Toddler Overalls 11.5" Inseam USA Made‎

Sanforization was invented in the late 1920s by American businessman and inventor, Sanford L. Cluett. Essentially, it’s a mechanical compaction process for woven fabrics. The fabric is fed in between two hot roll bars on top of a stretchy endless rubber belt. The fabric is first moistened, usually by steam. This lubricates the fibres and primes shrinkability. As the rubber returns to its original length once through the cylinders, the warp yarns shrink and the weft yarns are packed closer together. After the fabric leaves the rubber belt, it enters a dryer, which locks the fibres in their shrunken state.
