Abstract
There is disclosed a thermal bonding pattern for nonwoven fabric comprising a pattern having an element aspect ratio between about 2 and about 20 and an unbonded fiber aspect ratio of between about 3 and about 10. It has been unexpectedly found that such a fabric has a higher abrasion resistance and strength than a similar fabric bonded with different bond patterns of similar bond areas. This combination of strength and abrasion resistance has long been sought after.
