Thermoset polymer composite wires including a multiplicity of substantially continuous fibers embedded in a solidified polymer composite matrix and forming a substantially continuous filament, the solidified polymer composite matrix further including a polymer formed by curing a polymer precursor from a liquid state and a multiplicity of nanoparticles having a median diameter of one micrometer or less substantially uniformly dispersed throughout the polymer composite matrix, and optionally, a corrosion resistant sheath surrounding the substantially continuous filament. In some embodiments, the multiplicity of particles includes surface-modified particles having a core and a surface modifying agent associated with the core and reacted with the polymer cured from a liquid state. Stranded cables including one or more such thermoset polymer composite wires, and methods of making and using such thermoset polymer composite wires and stranded cables are also described.

A pressure steam treatment apparatus (1) according to the invention includes a pressure steam treatment chamber (10) and labyrinth sealing chambers (20) . The labyrinth sealing chambers (31, 33) are respectively arranged on a fiber bundle inlet and on a fiber bundle outlet of the steam treatment apparatus (1), having a running path of the fiber bundle in a horizontal direction and having plural labyrinth nozzles (24) on top and bottom of the running path. The difference (ΔH) between a maximum value and a minimum value of the distance in the perpendicular direction of the top and bottom side labyrinth nozzles (24), of a pair of opposing labyrinth nozzles (24) is 0.5 mm or smaller when the ambient temperature of the labyrinth sealing chamber is 140°C. This structure ensures that the energy cost necessary due to the leakage of pressure steam can be reduced, the deformation of the apparatus is prevented, and also, the raise of fuzz on the fiber bundle and fiber bundle breakage can be prevented at the same time.

A knitted casting glove that, when wetted, imparts a detackifying property to a sticky work surface. The glove comprises a knitted yarn of a base material and water-soluble material having a low dissolving point or a base material and a water-swellable material. The knitted casting glove may be worn over a standard examination glove.
摘要:
A porous element particularly for use as a tobacco smoke filter plug in association with a cigarette or the like wherein the matrix comprises a multiplicity of biodegradable polyvinyl alcohol fibers bonded together at their points of contact to define a tortuous interstitial path for the passage of smoke. Because of the hygroscopic nature of polyvinyl alcohol, commercial production of such products require careful control of the moisture content of the polyvinyl alcohol fiber starting material, usually pre-drying the same to a residual moisture content of 7% by weight or less, and treatment of the low moisture fibrous mass by superheated steam to add about 2.5 to 5% moisture to a final moisture content of about 2.5 to 10%. The steam renders the fiber surface adhesive and, thus, bondable, and also lubricates the gathered fibers to improve processability.
摘要:
A method and a slide-casting machine for casting one concrete product or several concrete products placed side by side at the same time by means of one casting machine using slide casting of high-consistency concrete mix. The concrete mix is fed by means of one feed member (2) or by means of several feed members placed side by side into one or several separate cross sections of a concrete product to be cast. The compacting of the concrete product or products to be cast is monitored by measuring the pressure of the concrete mix or the force arising from the pressure against a part (2; 9,7) of the casting machine at at least two points of the cross section and by separately regulating the operating values of at least two parallel feed members (2) or of the compacting movements of at least two parallel compacting members (3) on the basis of the measurement values obtained.

摘要:
Increased resistance to discoloration induced by smog or heat is imparted to a spandex fiber by incorporating within the fiber a phenolic antioxidant and a dialkyl phenyl phosphite in which at least half of the alkyl groups are branched at the alpha position and the phenyl groups are unsubstituted or monoalkyl substituted.
摘要:
A carbon fiber has a fiber tensile strength in a range of 5.5 GPa to 5.83 GPa. The carbon fiber has a fiber tensile modulus in a range of 350 GPa to 375 GPa. The carbon fiber also has an effective diameter in a range of 5.1 μm to 5.2 μm. In a method of making a carbon fiber, PAN (poly(acrylonitrile-co methacrylic acid)) is dissolved into a solvent to form a PAN solution. The PAN solution is extruded through a spinneret, thereby generating at least one precursor fiber. The precursor fiber is passed through a cold gelation medium, thereby causing the precursor fiber to gel. The precursor fiber is drawn to a predetermined draw ratio. The precursor fiber is continuously stabilized to form a stabilized fiber. The stabilized fiber is continuously carbonized thereby generating the carbon fiber. The carbon fiber is wound onto a spool.
