Soft continuous filament webs containing encapsulated filaments
Abstract
Abstract NONWOVEN WEBS CONPRISED OF A PLURAITY OF SUBSTANTIALLY CONTINUOUS AND RANDOMLY DEPOSITED, MOLECULARLY ORIENTED FILAMWENTS OF A THERMOPLASTIC POLYMER ARE DISCLOSED. THE WEBS CONTAIN EASILY RELEASABLE, INTERMITTENT AUTOGENEOUS BONDS AT A PLURAITY OF FILEMENT CROSSOVER POINTS. IN ADDITION, THE WEBS ARE STABILIZED BY MEANS OF AN EASILY DISRUPTABLE POLYMERIC MATERIAL WHICH ENCAPSULATES THE FILAMENTS AT INTERMITTENT, DISCRETE AREAS. THE WEBS CAN BE READILY PREPARED BY LIGHTLY HEAT BONDING A FLIMSY AND TENUOUS CONTINUOUS FILAMENT WEB TO FORM EASILY RELEASABLE AUTOGENEOUS BONDS AND, THEREAFTER, PRINTING THE WEB WITH A DISRUPTABLE POLYMERIC MATERIAL. WEBS SO FORMED POSSESS PARTICULARLY OUTSTANDING STRENGTH CHARACTERISTICS, ESPECIALLY WITH RESPECT TO ENERGY ABSORPTION AND TENSILE AND TEAR STRENGTH. IN ADDITION, THE SOFTNESS OF THE WEBS CAN BE ENHANCED BY A MODERATE "WORKING" OF THE WEB SO AS TO BRAKE THE EASILY RELEASABLE AUTOGENEOUS BONDS.
