Claim 1
Independent Claim
120 words
THE METHOD OF PRODUCING A FABRIC WITHOUT A PATTERNED CONFIGURATION WHICH INCLUDES A LAYER OF FIBROUS MATERIAL IN WHICH THE INDIVIDUAL FIBERS ARE CAPABLE OF MOVEMENT CREATED BY AN EXTERNAL FORCE WHICH IS A LIQUID IN THE FORM OF A JET STREAM WHICH COMPRISES LAYING A LAYER OF FIBERS ON AN OPEN TYPE SCREEN CONVEYOR TO FORM A LAYER OF FIBROUS MATERIAL, AND ADVANCING SAID CONVEYOR AND LAYER OF FIBROUS MATERIAL UNDER A PLURALITY OF LIQUID STREAMS WHICH PENETRATE INTO SAID FIBROUS MATERIAL, AND DRAW AND PULL THE FIBERS IN THE DIRECTION OF THE PENETRATION OF THE LIQUID STREAMS SO THAT THE INDIVIDUAL FIBERS ARE REORIENTED INTO AN ENTANGLEMENT WITH SUCCESSIVE FIBERS TO PROVIDE GREATER TENSILE STRENGTH TO SAID MATERIAL.
