  • Publication number: 20050043694
    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.

  • Publication number: 20050033252
    Abstract: The present invention relates to absorbent articles, such as diapers and sanitary napkins, and acquisition members useful for such articles. More specifically, the invention relates to an acquisition member comprising a multitude of fibers and a latex binder, the liquid acquisition member having a void volume of at least 7 cubic centimeter per gram in the temperature range from 20° C. to 40° C., the binder comprising a dispersion of a polymer substance in an essentially aqueous medium, the polymer substance being capable of forming a film, said film having a tan ? value, as defined herein, at 20° C. and at 40° C., wherein the tan ? value at 40° C. is not greater than said tan ? value at 20° C.

  • Patent number: 6643994
    Abstract: The present invention relates to a process for converting a continuous structure into discrete, spaced apart elements by means of an expandable support web. First, the continuous structure is combined with a support web comprising longitudinal expansion means. Then, after separation of the continuous structure into discrete elements, the discrete elements are spaced apart by expanding the support web. The process of the present invention is particularly well suited for the industrial manufacture of articles comprising fragile discrete elements supplied to the production process in continuous form.

  • Patent number: 6570058
    Abstract: The present invention is an absorbent structure with an ultimate fluid storage member, comprising superabsorbent material at a relatively high concentration whereby the superabsorbent material has a good Performance under Pressure performance as well as a good Saline Flow conductivity. Further, the absorbent structure comprises a non-woven wrap sheet comprising small diameter fibers, which is in direct fluid communication with said storage member, and which has low strike-through times in a repeated modified strike through test.
