  • 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: 20040170836
    Abstract: The present invention is directed to fibrous fabric comprising hollow fibers. Preferably, the fibrous fabrics will have an opacity greater than a fibrous fabric with an equivalent basis weight and made with the same material and the same fiber diameter. The fibrous fabric comprising hollow fibers may also have an opacity greater than a higher basis weight fibrous fabric containing the same material and having an equivalent fiber diameter and the same number of fibers. The perimeter of the hollow region of the hollow fibers is substantially non-concentric to the outer perimeter of the hollow polymeric fibers. The hollow fibers can be monocomponent and multicomponent, as well as monoconstituent or multiconstituent. These hollow fibers are then consolidated into woven and nonwoven fibrous fabrics that are then converted into articles.

  • Publication number: 20040161994
    Abstract: The present invention provides fibers (e.g. for nonwovens) that have high elongation to break at moderate to low fiber diameters. This is accomplished by spinning splittable multicomponent fibers under appropriate conditions to produce large diameter, low orientation fibers which can then be split into smaller segments that maintain the properties of the parent fiber. Thus, fibers are produced having elongations significantly higher than if a fiber of that same size had been spun directly.

  • Patent number: 6770356
    Abstract: The present invention relates to an intermediate web comprising of high glass transition polymer fibers. The fibers are spun at low to moderate speeds and have a relative crystallinity of from 10% to 75% of the maximum achievable crystallinity. The intermediate web is a low crystallinity web that exhibits shrinkage of more than 30% and elongation to break of more than 80% at high strain rates. This web can be heat treated to reduce shrinkage to less than 15% while the web is capable of at least about 60% elongation at a strain rate of at least about 50 second−1.

  • Patent number: 6743506
    Abstract: Splittable multicomponent fibers, to split fibers made from such splittable fibers, to a processes for making such splittable and split fibers, and to nonwovens and other substrates made form the split fibers. The splittable multicomponent fibers can comprise one component comprising thermoplastic starch and another component comprising a non-starch thermoplastic polymer, wherein: (i) said second component is capable of being split or removed from said first component to provide at least one split fiber consisting essentially of said first component; and (ii) wherein the split fiber of said first component can have good elongation properties. The splittable multicomponent fibers can also provide split fibers of the thermoplastic starch component.

  • Publication number: 20040096656
    Abstract: A melt spinnable multicomponent fiber is provided that comprises a first component comprising a starch insolubilizing agent and a thermoplastic polymer, and a second component comprising destructurized starch and a plasticizer. The insolubilizing agent acts on the starch of the second component to render the starch less soluble when the fiber is exposed to water. The invention is also directed to nonwoven webs and disposable articles comprising the multicomponent fibers.

  • Patent number: 6623854
    Abstract: A multicomponent fiber comprising one component comprising non-starch thermoplastic polymer and one component comprising a thermoplastic starch. The thermoplastic polymer component can surround the thermoplastic starch component. The thermoplastic starch can contain destructured starch and plasticizer. The multicomponent fiber has a greater elongation than a monocomponent thermoplastic fiber produced with the same thermoplastic polymer component materials and under the same processing conditions. Also provided are nonwoven webs and disposable articles comprising the multicomponent fibers.

  • 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.
