Claim 1

THE PROCESS FOR THE PRODUCTION OF BULKY FIBROUS MATERIAL COMPRISING THE FOLLOWING STEPS, IN COMBINATION, EXPOSING A SHRINKABLE FIBROUS MATERIAL TO A MEDIUM WHICH CHANGES THE SHRINKAGE POTENTIAL OF THE MATERIAL, SAID FIBROUS MATERIAL COMPRISING A PLURALITY OF ELONGATED FIBROUS UNITS, WHILE SUBSTANTIALLY INSULATING LONGITUDINALLY SPACED PORTIONS OF THE FIBROUS MATERIAL FROM SAID MEDIUM AND PERMITTING THE REMAINING LONGITUDINALLY SPACED PORTIONS OF THE FIBROUS MATERIAL TO CHANGE IN LENGTH, THUS PRODUCING AN INTERMEDIATE FIBROUS MATERIAL WHEREIN THE PORTIONS WHICH WERE INSULATED HAVE NOT BEEN SUBSTANTIALLY CHANGED IN LENGTH AND THUS ARE SUBSTANTIALLY UNCHANGED IN SHRINKAGE POTENTIAL AND THE OTHER PORTIONS HAVE BEEN CHANGED IN LENGTH AND THUS ARE SUBSTANTIALLY CHANGED IN SHRINKAGE POTENTIAL, RANDOMLY SHIFTING AT LEAST SOME OF SAID FILAMENTS LONGITUDINALLY WITH RESPECT TO ONE ANOTHER AND INTERLOCKING SAID FIBROUS MATERIAL AT SUCCESSIVE POINTS ALONG THE LENGTH OF THE FIBROUS MATERIAL SO THAT AT SAID POINTS SUBSTANTIALLY LONGITUDINAL MOVEMENT OF ADJACENT FIBROUS UNITS WITH RESPECT TO ONE ANOTHER IS RESTRAINED, SUBJECTING THE INTERLOCKED FIBROUS MATERIAL TO A TREATMENT WHICH INDUCES SHRINKAGE OF THE FIBROUS MATERIAL, WHEREBY THE PORTIONS RELATIVELY UNDIMINISHED IN SHRINKAGE POTENTIAL SHRINK SUBSTANTIALLY MORE THAN THE PORTIONS RELATIVELY DIMINISHED IN SHRINKAGE POTENTIAL AND THOSE PORTIONS OF THE FIBROUS UNITS WHICH SHRINK MORE EXERT AT SAID POINTS STRESS UPON PORTIONS OF ADJACENT FIBROUS UNITS WHICH SHRINK LESS, THEREBY CAUSING SAID LESSER SHRINKING PORTIONS TO BUCKLE, THUS IMPARTING BULK TO THE FIBROUS MATERIAL.
