The individual electrodes of the set are arranged at regular spacing to each other and at the same distance from the set's rotation axis, and parallel with it. The fibre is wound on the set of electrodes by rotating the set of electrodes. The electrostatic field is disconnected and rotation of the set of electrodes is stopped. A layer of the fibres formed in the field between two adjacent electrodes is removed. The rotating set of electrodes turns through an angle of 360/n, the layer of the fibres formed between two adjacent electrodes in the field adjacent to the field from which the layer was removed, is removed, and this step is repeated in total n-times.

Biocidal non-woven mats prepared by methods of the invention, incorporating the biocidal oligomers, can be used to suppress bacterial growth in wound and surgical dressings and personal hygiene products.

  • Publication number: 20140213136
    Abstract: A fibrous properties-switching article comprises a mat consisting of fibers having a fiber diameter of 2 microns or less. The fibers comprise a polymer, copolymer, polymer blend, or polymer network, wherein the fibers have a diameter of 2 gm or less. The surface and/or bulk property of the mat changes over a range of temperatures, wherein the polymer, copolymer, polymer blend, or polymer network undergoes a structural change over the range of temperatures. The fiber mat is formed by electrospinning. In an exemplary embodiment, a blend of polystyrene and poly((N-isopropyl acrylamide) (b1-PS/PNIPA) in dimethylformamide (DMF) is electrospun to form a mat consisting of fibers with a diameter less than 2 ?m that shows a transition from a superhydrophilic surface to a nearly superhydrophobic surface over a temperature range from 30° C. to 45° C.

  • Publication number: 20140154507
    Abstract: The present invention relates to a regenerated cellulose fiber having a multi-limbed cross-section. The fiber according to the invention is characterized in that the cross-section is formed of at least two multi-limbed basic shapes (1?, 2?, 3?, 4?), which basic shapes are connected, in each case at least at one of their limb ends, to the limb end of another basic shape and the length of the connecting limb (12) resulting from the connection of the two limb ends is longer than the length of the shortest one of the other limbs by a factor of at least 1.5, preferably of from 1.5 to 2.0.

  • Publication number: 20140121622
    Abstract: Disclosed herein is a cellulosic textile filament made from microfibrillar cellulose fibers and a thickening agent as well as the precursor dope for forming such filaments, nonwoven webs made from such cellulosic textile filaments and the process for forming such filaments and nonwoven webs including such filaments. One of the advantages of these filaments is the eco-sensitive way in which they are made as they utilize a water-based dope that does not require any chemical solvents unlike other processes such as those used to make Lyocell fibers. In addition, the process does not involve any washing or extraction steps and it employs a cellulosic fiber source that is broadly based and renewable.
