Recent research on all aspects of thermally point-bonded nonwovens has led to considerable improvements in the understanding of material requirements for these nonwovens; the changes that occur during bonding; and the mechanical properties of the resultant nonwoven materials. This article will review (1) how the thermal bonding process transforms the material properties of feed fibers; (2) the implications for material selection; and (3) the resultant failure properties of the bonded nonwoven. The formation of a bond during thermal bonding follows in sequence through three critical steps: (1) heating the web to partially melt the crystalline region; (2) reptation of the newly released chain segments across the fiber-fiber interface; and (3) subsequent cooling of the web to re-solidify it and to trap the chain segments that diffused across the fiber-fiber interface. The time scales for these processes closely match commercial practice. In addition; adequate pressure is required to compress the fibers that form the bond spots and enhance heat transfer to these fibers. However; pressures typically used in commercial practice are insufficient to increase the melting temperature significantly or to produce significant heating due to compression of the fibers. © 2005 Wiley Periodicals; Inc;
