✦ Synopsis

In addition to enhanced absorbency, handsheets incorporating hydrolyzed methyl-acrylate-grafted (HMAG) Kraft fibers exhibit enhanced tensile strength and stretchability [E. Rezai and R. R. Warner, J. Appl. Polym. Sci., 00, 000 (19XX)]. These handsheets have a unique morphology. In a handsheet, grafted fibers form stretched planar sheets that appear to bond with neighboring ungrafted fibers. This meshwork of interwoven, stretched cellulose/polymer sheets bonding with normal ungrafted fibers likely accounts for the enhanced tensile strength and stretchability of HMAG-containing handsheets. Analytical electron microscopy is shown to be a useful technique for investigating polymer-grafted fibers in handsheets.
