摘要： A method for producing ultrafine fibers of the present invention includes forming an electric field between an discharging nozzle from which a raw resin is discharged and a charging electrode which is disposed apart from the discharging nozzle, and supplying the raw resin which has been heated and melted into the electric field from the discharging nozzle to spin the raw resin. The raw resin is a resin mixture which contains a resin having a melting point and an additive, and satisfies a relation (I) below: A/B≥1.0×102  (I) wherein A represents the absolute value (Ω) of electrical impedance of the raw resin at 50° C., and B represents the absolute value (Ω) of electrical impedance of the raw resin at a temperature 50° C. higher than a melting point of the raw resin.

摘要： Bacteria-responsive core-shell nanofibers and a process for the preparation thereof are described. The nanofibers release of an antibacterial agent in response to the presence of bacteria. The core of the nanofiber comprises a biocompatible polymer together with an antibacterial agent such as a quaternary ammonium compound, for example benzyl dimethyl tetradecyl ammonium chloride (BTAC). Surrounding the core is shell comprised of a bacterially degradable polymer, which is susceptible to break-down by bacterial enzymes such as lipase, or to acidic pH conditions. The shell may comprise, for example, polycaprolactone (PCL) and poly(ethylene succinate) (PES). The nanofibers may be incorporated into wound dressings.

摘要： A fiber having both thermal-insulating and cool-feeling functions and a fabric having both thermal-insulating and cool-feeling functions are provided. The fiber includes a thermal-insulating part and a cool-feeling part encapsulating the thermal-insulating part. A material of the thermal-insulating part includes a first base material and a near infrared reflective material dispersed in the first base material. The near infrared reflective material is selected from the group consisting of iron, cobalt, chromium, copper, nickel, bismuth, and an alloy thereof. A material of the cool-feeling part includes a second base material and a cool feeling material dispersed in the second base material. The cool feeling material is a silicate containing at least one metal selected from the group consisting of calcium, magnesium, sodium, and aluminum. The fabric having both thermal-insulating and cool-feeling functions is woven from the fiber having both thermal-insulating and cool-feeling functions.

摘要： A medical device having a tubular membrane with openings adapted to receive the ends of an injured nerve and a lumen to allow the regeneration of the nerve, such that the tubular membrane includes fibers of polyhydroxyalkanoate (PHA) containing 3-hydroxybutyrate monomer units. The fibers have an average diameter from 500 nm to 2000 nm. Preferably, the PHA is a poly-3-hydroxybutyrate homopolymer and the tubular membrane further includes silver nanowires (Ag). The medical device has the advantages of not causing inflammation of the surrounding tissues surrounding the injured nerve, thus demonstrating a high biocompatibility, and at the same time exhibiting high ability to induce the regeneration of the injured nerve, providing a valid support for the maturation of the newly formed nerve fibers.

摘要： A novel process is disclosed for extruding an absorbable glycolide/lactide block copolymer into multifilament suture fibers. The block copolymer preferably consists of about 50/50 mole % of Glycolide/Lactide in the center segment and the overall composition of the copolymer is about 90/10 mole % Glycolide/Lactide. The novel extrusion process comprises the steps of maintaining the temperatures of at least two, preferably three or more, of the extrusion zones in the range of about 5-50° C. below the polymer melting point. The multifilament suture made with the invention process from the segmented, glycolide-rich, poly(glycolide-co-lactide) copolymers of A-B-A type, where the B-segment is an amorphous prepolymer of glycolide and lactide in the molar ratio of about 50/50 glycolide/lactide, exhibit exceptionally high breaking strength retention (BSR) at 42 days post-implantation.

摘要： Composite nanofibers comprising polymers and tannins, methods of making same, and methods of use. The nanofibers include a polymer, such as a synthetic polymer, and a tannin. The tannin can include condensed tannins (proanthocyanidins) and/or hydrolyzable tannins. The nanofibers exhibit a number of structural and functional characteristics, such as enhanced swelling in aqueous liquid, enhanced antibacterial activity, enhanced bacterial adsorption, enhanced fibroblast adhesion, enhanced fibroblast proliferation, and enhanced surface coating of silver nanoparticles, among others. The nanofibers can be made by electrospinning a solvent mixture comprising the synthetic polymer and the tannin in a solvent. The nanofibers can be used in methods of isolating cells, methods of filtration, and methods of detecting cells, among others.

摘要： An article, such as an article of footwear includes, a textile component. The textile component includes a yarn. The yarn includes a thermoplastic material and a blowing agent with an activation condition. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material, creating a multicellular foam area of the textile.
