Researchers plumb the secrets of tissue paper

A team working with UBC mechanical engineering professors Sheldon Green and Srikanth Phani have created what is likely the first complete mathematical model of creping, the crinkling process that helps make tissue paper soft and resilient.
During tissue manufacture, pulp is dried on a chemical-coated rotating drum until it's 95 per cent dry. It's then pushed off at very high speeds by a sharp creping blade, creating hundreds of microscopic folds that give tissue its softness, flexibility, tearing resistance and strength.
