Abstract
Abstract LAMINATES COMPRISING A CELLULOSIC WEB AND A WEB OF CONTINUOUS THERMOPLASTIC FILAMENTS ARE DISCLOSED. THE CONTINUOUS FILAMENT WEB IS BONDED BY MEANS OF AN INTERMITTENT PATTERN OF SPOT BONDS WHICH ARE CHARACTERIZED BY THEIR ABILITY TO RELEASE BONDED FILAMENTS AT LEVELS OF STRAIN APPROACHING BUT LESS THAN THE BREAKING STRENGTH OF THE FILAMENTS. THE DISCLOSED LAMINATES ARE STRONG, ATTRACTIVE IN APPEARANCE, CAN ABSORB AND RETAIN FLUID, AND POSSESS DESIRABLE ENERGY ABSORPTION CHARACTERISTICS, ESPECIALLY OVER SMALL LAMINATE ELONGATIONS.
