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.

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.

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.

Hemicellulose fibers, more particularly to non-naturally occurring fibers incorporating hemicellulose, processes for making same and fibrous structures incorporating same are provided.

Fibers comprising hemicellulose and processes for making same

A method for making a fibrous structure including a plurality of synthetic fibers disposed in a predetermined pattern and a plurality of cellulosic fibers generally randomly distributed throughout at least one layer of the fibrous structure. The method includes depositing an aqueous slurry including synthetic fibers and an aqueous slurry including cellulosic fibers onto a fluid-permeable forming member having a pattern of channels. The slurries are dewatered to form a fibrous web, wherein the at least some of the cellulosic fibers are randomly distributed throughout at least a portion of the fibrous web and a plurality of synthetic fibers are at least partially non-randomly distributed in the channels. A fluid pressure differential is applied to the fibrous web disposed on the forming member, thereby molding the fibrous web such that the fibrous web includes a first plurality of micro-regions corresponding to a plurality of fluid-permeable areas of the forming member and a second plurality of micro-regions corresponding to a plurality of fluid-impermeable areas of the forming member.
