  • Patent number: 7767598
    Abstract: A liquid acquisition layer having a multitude of fibers and a binder is useful in a variety of absorbent articles, such as diapers and sanitary napkins. The liquid acquisition layer has a caliper which decreases in response to external pressure and increases upon removal of said external pressure. The increase in caliper is measured by a recovery value, wherein the liquid acquisition layer recovery value at 45° C. is at least 65% of the recovery value at 20° C.
