  • Patent number: 7041369
    Abstract: The present invention relates to starch compositions which contain starch and additives. The starch has a weight average molecular weight ranging from about 1,000 to about 2,000,000. The additives can be plasticizers or diluents. The composition containing the starch and the additive is formed by means of passing the composition through a die to produce fibers, foams or films. These compositions have an extensional viscosity in the range from about 50 to about 20,000 pascal seconds. The starch compositions preferably contain a polymer that is substantially compatible with starch and has a weight-average molecular weight of at least 500,000.

  • Patent number: 6989075
    Abstract: A dual intensive property tissue. The tissue has a first set of intensive properties including density, surface area, thickness and void volume as presented to the consumer. The consumer plastically activates the tissue by pulling it in tension. A series of slits 44 or other lines of weakness elongate in a direction parallel to the line of tension, allowing the tissue to achieve a second state of intensive properties. The value of the second state of intensive properties is different after activation. The change in value of the intensive properties allows for economies in shipping, where a higher density product is shipped to the consumer. At the point of use, the consumer activates the product to achieve the increase surface area and lower density. The increase in surface area and concomitant decrease in density provides for increased efficacy in cleaning. The plastically activatable state may be provided by a series of slits 44 or other lines of weakness in the tissue.
