  • 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: 20140250646
    Abstract: Techniques produce intertwining knots in a multifilament thread. In such techniques, an air stream pulse is generated by a nozzle channel opening into a treatment channel periodically with an interval between successive air stream pulses. During an interval, the air stream pulse is directed transversely onto the thread guided in the treatment channel so that a continuous sequence of intertwining knots is produced in the running thread. An auxiliary air stream is generated continuously or discontinuously and the auxiliary air stream and the air stream pulse are blown in together into the treatment channel.

    Abstract: The tension member for a belt of this invention is made from a glass cord. First twist yarns of this glass cord are obtained by paralleling and twisting a plurality of fiber bundles, each including a large number of glass filaments, by a predetermined first twist number. The fiber bundles are previously soaked with a treatment liquid including a mixture of rubber latex and an initial condensation product of resorcinol and formalin as a main component and then heated. The glass cord is fabricated by paralleling a predetermined number of the first twist yarns and twisting them by a predetermined final twist number, so as to squeeze and substantially eliminating spaces among the first twist yarns. Accordingly, the belt including this glass cord as the tension member can achieve good water resistance because externally intruding water is prevented from being held within the belt.

  • Patent number: 5360503
    Abstract: The semi-finished product according to the invention consists exclusively of liquid crystal thermoplastic polymers (LCP), whereof at least one first liquid crystal thermoplastic polymer (LCP) is in the form of fibers (18) and has a given melting point, and whereof at least one second liquid crystal thermoplastic polymer (LCP) (16) has a melting point below that of the first LCP. This semi-finished product is in particular a fabric. By simply heating under pressure at a temperature equal to the melting point of the second LCP, followed by cooling, a composite material with improved mechanical and physicochemical performance characteristics are obtained.

  • Patent number: 5277850
    Abstract: The present invention relates to a carbon fiber bundle includes a regular coil-shaped fiber bundle and having excellent stretch characteristic. A process for producing a coil-shaped carbon fiber bundle according to the present invention includes the steps of compositing at least two kind of pitches to spin them as single fibers, bundling the thus spun single fibers to form a fiber bundle, then infusibilizing the resulting fiber bundler under tension and carbonizing the fiber bundle.

  • Patent number: 5232769
    Abstract: This invention relates to a microcapsule having a particle diameter of 2.about.300 .mu.m and comprising a substance acting to improve physiological conditions of human skin, for example, substances exhibiting such effects as skin whitening, aging preventive, humidity preservable, itch suppressive, pain-killing, or antiphlogistic ones, and/or aromatic agents contained within the filmy coating of synthetic high molecular substance. The microcapsule is not broken when making, processing, or laundering the textile structure, but is gradually broken when the textile structure is put on the human body, used for another purpose, or subjected to intentional application of friction or pressure thereto, and sustainedly releases acting substances contained therein.

  • Patent number: 5165993
    Abstract: The invention relates to a filament yarn of aromatic polyamides which is impregnated with solid particles of a fluorine-containing polymer and/or graphite. The solid particles are incorporated into the yarn by very uniformly distributing them over the filaments in that the solid particles are applied to the yarn from an aqueous dispersion and the yarn is subjected to a blowing treatment while feeding them at an excess feed rate or not. The yarn thus impregnated is first of all intended to be processed into a packing material or rope.
