Compressively deformed cellulosic laminates with improved drape,bulk,and softness
Abstract
Abstract A SOFT, BULKY CELLULOSIC LAMINTED IS ILLUSTRATED. THE LAMINATE COMPRIES AN AIRLAID WEB OF CELLULOSIC FIBERS CONTAINING A PATTERN OF HIGHLY COMPACTED SPOT-BONDED AREAS AND FLUFFY MOUND REGIONS OF SUBSTANTIALLY UNBONDED FIBERS DISPOSED BETWEEN THE BONDED AREAS. THE CELLULOSIC WEB IS UNITED TO A NETWORK OF REINFORCING ELEMENTS SUCH AS A SCRIM DRAFTED FIBER WEB OR CONTINOUS FILAMENT WEB WITH A LAYER OF PATTERN ADHESIVE CONTAINING OPEN AREAS OF A MAGNITUDE AT LEAST SEVERAL TIMES GREATER THAN THE SPACINGS BETWEEN THE SPOT BOND AREAS IN THE CELLULOSIC WEB. THE LAMINATE IS COMPRESSIVELY DEFORMED SUCH AS BY MICROCERPING TO ENCHANCE SOFTNESS AND BULKINESS BY ACCENTUATING THE UNBOUNDED AND FLUFFY CHARACTERISTICS OF THE MOUNDS IN THE CELLULOSIC WEBS WHICH ARE DISPOSED WITHIN THE OPENED AREAS OF THE ADHESIVE LAYER.
