  • Patent number: 5509915
    Abstract: Generally stated, the present invention provides a distinctive absorbent article comprising a backsheet layer, and a topsheet layer which is disposed in facing relation with the backsheet layer. An absorbent body is interposed between the backsheet layer and topsheet layer. The absorbent body includes a retention portion which comprises a matrix of substantially hydrophilic fibers having a distribution of high-absorbency particulate material therein. The hydrophilic fibers and high-absorbency particles can be provided in a fiber-to-particle weight ratio within the range of about 70:30 to about 30:70. A surge management layer, comprising bicomponent fibers having a denier of not more than about 3 d, is located adjacent at least one major, facing surface of the topsheet layer, and can cooperate with the article components to provide for a liquid Penetration Rate index of not less than about 2.67 ml/sec.

  • Patent number: 4135960
    Abstract: Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed. A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film. Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relationships are maintained between the ink films and the release film. An adhesive film may be formed on the article to be printed, or it may be formed over the ink films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.
