The effect of this action shortens the warp yarns, which packs the weft (filling yarns) closer together. Next, the cotton is fed into the pressure zone and upon leaving it, the surface returns to its pre-squeezed (stretched) size. Second, the cotton strands enter an endless rubber belt and belt squeeze them between a pressure roll and a rubber belt cylinder to stretch out the denim dramatically. Or in more detail, the cotton is first moistened by water and/or steam in order to soak the cotton fibres and join them closer together as strands.
Sanforization is a post-weave process patented by Sanford Lockwood Cluett in 1930 and known for its ability to shrink denim that would be otherwise shrunk down later in the consumer process after washing.
