摘要:
The present invention pertains to polymer fibers obtainable by melt spinning at least one polymer and/or by processing at least one polymer in non-woven melt processes. The polymer fibers in accordance with the present invention exhibit a substantial free swell absorbency, rendering them suitable for use in inter alia absorbent products, for instance wound dressings. Additionally, the present invention relates to processes for obtaining said polymer fibers, absorbent articles comprising said fibers, as well as uses of said polymer fibers in products for treating wounds and/or bums.

A method comprising: providing at least one first composition comprising at least one conjugated polymer and at least one solvent, wet spinning the at least one first composition to form at least one first fiber material, hot-drawing the at least one fiber to form at least one second fiber material. In lead embodiments, high-performance poly(3,4-ethylenedioxy-thiophene)/poly(styrenesulfonate) (PEDOT/PSS) conjugated polymer microfibers were fabricated via wet-spinning followed by hot-drawing. In these lead embodiments, due to the combined effects of the vertical hot-drawing process and doping/de-doping the microfibers with ethylene glycol (EG), a record electrical conductivity of 2804 S·cm−1 was achieved. This is believed to be a six-fold improvement over the best previously reported value for PEDOT/PSS fibers (467 S·cm−1) and a twofold improvement over the best values for conductive polymer films treated by EG de-doping (1418 S·cm−1). Moreover, these lead, highly conductive fibers experience a semiconductor-metal transition at 313 K. They also have superior mechanical properties with a Young's modulus up to 8.3 GPa, a tensile strength reaching 409.8 MPa and a large elongation before failure (21%). The most conductive fiber also demonstrates an extraordinary electrical performance during stretching/unstretching: the conductivity increased by 25% before the fiber rupture point with a maximum strain up to 21%. Simple fabrication of the semi-metallic, strong and stretchable wet-spun PEDOT/PSS microfibers can make them available for conductive smart electronics. A dramatic improvement in electrical conductivity is needed to make conductive polymer fibers viable candidates in applications such as flexible electrodes, conductive textiles, and fast-response sensors and actuators.

摘要:
The present invention provides an all-aqueous process and composition for production of silk biomaterials, e.g., fibers, films, foams and mats. In the process, at least one biocompatible polymer, such as poly(ethylene oxide) (PEO) (a well-documented biocompatible material), was blended with the silk protein prior to processing e.g., electrospinning. We discovered that this step avoids problems associated with conformational transitions of fibroin during solubilization and reprocessing from aqueous solution which lead to embrittled materials. Moreover, the process avoids the use of organic solvents that can pose problems when the processed biomaterials are exposed to cells in vitro or in vivo.

摘要:
A fiber is prepared by melt extruding a composition including specific amounts of a polyamide and a polyphenylene ether along with a compatabilizer. Particular combinations produce fibers having a desirable combination of good tenacity and low denier per fiber. Compared to a fiber prepared from polyamide alone, the present fiber exhibits improved heat resistance and flame resistance.
