    摘要： The present invention provides methods of making micron, submicron or nanometer dimension thermoplastic polymer microfibrillar composites and fibers, and methods of using the thermoplastic polymer microfibers and nanofibers in woven fabrics, biocidal textiles, biosensors, membranes, filters, protein support and organ repairs. The methods typically include admixing a thermoplastic polymer and a matrix material to form a mixture, where the thermoplastic and the matrix are thermodynamically immiscible, followed by extruding the mixture under conditions sufficient to form a microfibrillar composite containing a plurality of the thermoplastic polymer microfibers and/or nanofibers embedded in the matrix material. The microfibers and/or nanofibers are isolated by removing the surrounding matrix. In one embodiment, the microfibrillar composite formed is further extended under conditions sufficient to form a drawn microfibrillar and/or nanofibrillar composite with controlled diameters.

    摘要： A fiber containing an eggshell membrane component. The fiber is produced by spinning using a solution containing the eggshell membrane component by employing an electrospinning method. A fiber assembly formed from the fiber obtained by employing the electrospinning method imitates a natural eggshell membrane, whereby sufficient air permeability is exhibited. Since the fiber assembly is also excellent in adherence to skin tissue of a human body and stypticity, the fiber assembly may be preferably used as a wound dressing or a cosmetic sheet.

    摘要： 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.
