Abstract
Improved tissue, continuous filament nonwoven laminates which are characterized by relatively high strength or toughness, relatively high loft and drape together with low noise or paper-like rattle. The improved tissue, continuous filament nonwoven laminates, while exhibiting a relatively high strength, are comprised of a low tensile strength, low basis weight, lightly bonded or unbonded layer of continuous filament nonwoven which is impregnated with about 50% to about 120%, based on the continuous filament nonwoven layer basis weight, of soft, tacky latex solids. The impregnated continuous filament nonwoven is combined under minimum combining pressures, while in the impregnated moist state between at least two, soft absorbent tissue facing layers prior to drying the laminate and curing the latex solids.
