  • Patent number: 9925706
    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.

  • Patent number: 8287693
    Abstract: A papermaking belt for carrying an embryonic web of paper fibers is disclosed. The papermaking belt has an embryonic web contacting surface and a non-embryonic web contacting surface opposite thereto. The papermaking belt also has a reinforcing structure having a patterned framework disposed thereon and a plurality of non-random distinct pores disposed within the continuous network region. The patterned framework has a continuous network region and a plurality of discrete deflection conduits. The deflection conduits are isolated one from another by the continuous network region. Each of the pores has an opening disposed at a predetermined location upon the embryonic web contacting surface and an opening disposed at a predetermined location upon the non-embryonic web contacting surface. Each of the pores defines a single pathway between the embryonic web contacting surface and the non-embryonic web contacting surface.
