  • Patterned felts for bulk and visual aesthetic development of a tissue basesheet
    Patent number: 6610619
    Abstract: A method of imparting bulk and/or visual aesthetics to a tissue basesheet involves pressing the basesheet with a felt having a raised pattern on it so that the pattern becomes inherent in the sheet. A pattern is stitched into a carrier layer which is joined to a substrate to form the felt. As the basesheet is pressed into the felt, the raised pattern displaces fibers in the sheet, effectively inducing the pattern in the basesheet. The novel felt with a raised patterned layer is also disclosed.
