  • Patent number: 6562168
    Abstract: A web including a fibrous material and superabsorbent material is fed to a station. The web has a first surface, a second surface, a first side edge and a second side edge. At the station, the operation of applying a superabsorbent material movement obstruction agent and cutting the web into individual absorbent members having a pair of opposing cut ends are carried out simultaneously.

  • Patent number: 6391389
    Abstract: A web (110) including a fibrous material and superabsorbent material is fed to a knife (120). The web (110) has a first surface, a second surface, a first side edge and a second side edge. The knife (120) cuts the web (110) into individual absorbent members having a pair of opposing cut ends. The individual absorbent members have a first surface, a second surface, a first side edge, a second side edge, a first end edge and a second end edge, with the first and second end edges corresponding to the cut ends. A flowable superabsorbent movement obstruction agent (122) is applied to the cut ends.

  • Patent number: 5882464
    Abstract: Absorbent articles having absorbent cores comprising multiple absorbent layers which are joined to each other. In particular, absorbent structures which have one of the absorbent layers being shorter in the manufacturing direction than at least one of the other layers and which are joined to one of the other layers by crimping and a process of crimping of a central patch of a fibrous web to a tissue.

  • Patent number: 5698510
    Abstract: A process for making granular detergent compositions or components comprising from about 35% to about 85% by weight of a surfactant system comprising a mixture of polyhydroxy fatty acid amide and ethoxylated nonionic surfactant. The surfactant system is in the solid phase at temperatures of 25.degree. C. and below, and has a softening point from above 25.degree. C. to 100.degree. C. Additionally, the surfactant system has a viscosity profile whereby its viscosity is at least about 20,000 cps at a temperature of 10.degree. C. above the softening point, and less than about 10,000 cps at a temperature of 30.degree. C. above the softening point, all viscosities being measured at a shear rate of 25 s.sup.-1.
