    Abstract: A production method of an elastically stretchable artificial leather which includes a step of making microfiberizable fibers into a web; a step of entangling the obtained web to produce an entangled nonwoven fabric; a step of converting the microfiberizable fibers in the nonwoven fabric to microfine fibers, thereby producing a substrate for artificial leather; a step of producing an artificial leather by using the obtained substrate for artificial leather; and a step wherein the obtained artificial leather is brought into close contact with an elastomer sheet stretched in a machine direction by 5 to 40%; the artificial leather is allowed to shrink in the machine direction simultaneously with allowing the elastomer sheet to shrink in the machine direction by relaxing elongation of the elastomer sheet; the artificial leather is heat-treated in shrunk state; and then the artificial leather is peeled off from the elastomer sheet.

  • Publication number: 20150040532
    Abstract: A fiber of carbon nanotubes was prepared by a wet-spinning method involving drawing carbon nanotubes away from a substantially aligned, supported array of carbon nanotubes to form a ribbon, wetting the ribbon with a liquid, and spinning a fiber from the wetted ribbon. The liquid can be a polymer solution and after forming the fiber, the polymer can be cured. The resulting fiber has a higher tensile strength and higher conductivity compared to dry-spun fibers and to wet-spun fibers prepared by other methods.

  • Publication number: 20150044449
    Abstract: High-melting antimicrobial polymer fibers and antimicrobial fabrics comprising such fibers are prepared by preparing a masterbatch of polymer pellets (e.g., PET), silver and copper salts, and a compounding agent which provides free flowing polymer pellets which can be prepared in advance, with a long shelf life. Polymer masterbatches prepared by the methods of the invention can produce limited color or off-white antimicrobial fibers and fabrics using conventional melt spinning manufacturing methods. Fabrics incorporating fibers of the present invention are potent inhibitors of Athlete's foot fungi, gram negative and gram positive bacteria, and drug resistant pathogens.

  • Publication number: 20150033937
    Abstract: A method and apparatus for producing boron nitride nanotubes and continuous boron nitride nanotube yarn or tapes is provided. The apparatus includes rotating reaction tubes that allow for continuous chemical vapor deposition of boron nitride nanotubes. The rotation of the reaction tubes allows the boron nitride nanotubes to be spun into yarns or made into tapes, without post process or external rotation or spinning of the gathered nanotubes. Boron nitride nanotube yarns or tapes of great length can be produced as a result, thereby providing industry with a readily useable format for this type of material. Dopants such as carbon can be added to engineer the band gap of the nanotubes. Catalysts may be formed outside or inside the reactor.

    Abstract: Continuous processing methods are used for making absorbable polymeric non-wovens, with anisotropic properties, improved mechanical properties and without substantial loss of polymer molecular weight during processing. The method includes producing dry spun-non wovens from a polymer, and collecting the fibers using a rotating collector plate, preferably a rotating cylinder, to collect the non-woven instead of a fiberglass stationary collector plate. The non-wovens can be used for a variety of purposes including fabrication of medical devices.
