  • Patent number: 7265067
    Abstract: A papermaking belt for dewatering and imprinting a paper web. The belt comprises two laminae joined together in a face to face relationship to form a unitary laminate. The first lamina comprises a foraminous imprinting member which may serve as a reinforcing structure for a patterned framework. The second lamina comprises a secondary base and a batting which is joined to the secondary base to form a dewatering felt. The two lamina are juxtaposed and attached such that batting from the second lamina extends through the foraminous imprinting member of the first lamina providing a hydraulic connection therebetween.

  • Publication number: 20040197554
    Abstract: The present invention is directed to multicomponent fibers. The fibers may be in a side-by-side, sheath-core, segmented pie, islands-in-the-sea configuration, or any combination of configurations. Each component of the fiber will comprise destructurized starch and/or a thermoplastic polymer. The present invention is also directed to nonwoven webs and disposable articles comprising the multicomponent fibers. The nonwoven webs may also contain other synthetic or natural fibers blended with the multicomponent fibers of the present invention.

  • Publication number: 20030148690
    Abstract: A melt spinnable fiber is provided that comprises a first component comprising a thermoplastic polymer, and a second component comprising thermoplastic starch where the second component is not encompassed by another component or components or if encompassed by another component or components then the second component encompasses a hollow core. A particular use of such a fiber is for removal of the second component in the presence of a solvent in order to produce fibers with desired properties. An agent may be present in the second component for controlling the rate of removal of the second component thereby allowing for physical manipulation of the fiber prior to complete removal of the component. The invention is also directed to nonwoven webs and disposable articles comprising the fibers.
