Fibrous structures and methods of making the same

Claim 1

A METHOD OF IMPROVING THE PHYSICAL PROPERTIES OF A FIBROUS STRUCTURE CONTAINING POTENTIALLY ABHESIVE FIBERS CAPABLE OF BEING RENDERED TACKY BY TREATMENT WITH AQUEOUS CHLORAL WHICH COMPRISES: FORMING A FIBROUS STRUCTURE COMPRISING AT LEAST ABOUT 5% BY WEITH OF POTENTIALLY ADHESIVE FIBERS CAPABLE OF BEING RENDERED LACKY BY TREATMENT WITH AQUEOUS CHLORAL AND LESS THAN ABOUT 95% BY WEIGHT OF FIBERS ADHESIVELY UNAFFECTED BY AQUEOUS CHLORAL; TREATING THE FIBROUS STRUCTURE WITH AN AQUEOUS CHLORAL SOLUTION CONTAINING DISSOLVED THEREIN A SYNTHERIC, POLYMERIC, HIGH MOLECULAR WEIGHT MATERIAL CAPABLE OF DISSOLVING IN AQUEOUS CHLORAL SOLUTION, WHEREBY THE POTENTIALLY ADHERSIVE FIBERS ARE RENDERED TACKY AND ARE BONDED TO EACH OTHER AT THEIR POINTS OF CONTACT; AND TREATING SAID BONDED FIBROUS STRUCTURE WITH AN AQUEOUS COAGULATING MEDIA WHEREBY THE DISSOLVED SYNTHETIC, POLYMERIC, HIGH MOLECULAR WEIGHT MATERIAL IS PRECIPHATED OUT OF THE CHLORAL SOLUTION ANDIS DEPOSITED ON THE POTENTIALLY ADHESIVE FIBERS WHEREBY THEY ARE COATED IN ADDITION TO BEING BONDED, THUS PROVIDING PROPERTIES OF INCREASED STRENGTH AND IMPROVED ABRASION RESISTANCE IN THE FIBROUS STRUCTURE WITHOUT LOSS OF ITS FIBROUS CHARACTER.

Claim 2

A METHOD OF IMPROVING THE PHYSICAL PROPERTIES OF A FIBROUS STRUCTURE CONTAINING POTENTIALLY ABHESIVE FIBERS CAPABLE OF BEING RENDERED TACKY BY TREATMENT WITH AQUEOUS CHLORAL WHICH COMPRISES: FORMING A FIBROUS STRUCTURE COMPRISING AT LEAST ABOUT 5% BY WEITH OF POTENTIALLY ADHESIVE FIBERS CAPABLE OF BEING RENDERED LACKY BY TREATMENT WITH AQUEOUS CHLORAL AND LESS THAN ABOUT 95% BY WEIGHT OF FIBERS ADHESIVELY UNAFFECTED BY AQUEOUS CHLORAL; TREATING THE FIBROUS STRUCTURE WITH AN AQUEOUS CHLORAL SOLUTION CONTAINING DISSOLVED THEREIN A SYNTHERIC, POLYMERIC, HIGH MOLECULAR WEIGHT MATERIAL CAPABLE OF DISSOLVING IN AQUEOUS CHLORAL SOLUTION, WHEREBY THE POTENTIALLY ADHERSIVE FIBERS ARE RENDERED TACKY AND ARE BONDED TO EACH OTHER AT THEIR POINTS OF CONTACT; AND TREATING SAID BONDED FIBROUS STRUCTURE WITH AN AQUEOUS COAGULATING MEDIA WHEREBY THE DISSOLVED SYNTHETIC, POLYMERIC, HIGH MOLECULAR WEIGHT MATERIAL IS PRECIPHATED OUT OF THE CHLORAL SOLUTION ANDIS DEPOSITED ON THE POTENTIALLY ADHESIVE FIBERS WHEREBY THEY ARE COATED IN ADDITION TO BEING BONDED, THUS PROVIDING PROPERTIES OF INCREASED STRENGTH AND IMPROVED ABRASION RESISTANCE IN THE FIBROUS STRUCTURE WITHOUT LOSS OF ITS FIBROUS CHARACTER.
