Abstract
Creped tissues having improved perceived softness and appearance are made from tissue webs having at least a machine direction broken line pattern of individual densified areas containing higher mass concentrations of fibers. The broken line pattern of densified areas creates a pleasing appearance and influences the creping to provide a more uniform crepe and hence improved tissue softness.
