Abstract A newly developed coaxial dielectric barrier discharge reactor with a length of 1000 mm at an atmospheric pressure was used for plasma treatment of polyester fiber cord in a roll-to-roll manner. In this reactor, swirling mixture gases of oxygen of about 1% and argon with a flow rate of 1.5 L/rain to 2.7 L/min ensured the gas usage sparing, discharge uniformity and efficient fiber surface modification. The water contact angle and surface morphology of the treated fiber were measured. The results show that the surface oxygenation is mainly responsible for the wettability improvement of the fiber cord when passing through the plasma zone at a linear speed of 3 m/min to 8 m/rain. The specimens of modified-polyester fiber reinforced rubber composite were also prepared for the interracial shear strength tests. Furthermore, the effect of adding oxygen into argon discharge on the fiber surface oxidation was correlated with optical emission spectroscopy. Finally, the effect of adding oxygen into argon discharge on the kinetic processes of the active species generation were also analyzed.

Using the hydrogen-bonding interaction between graphene oxide（GO） and sulfonated polyethersulfone （SPES）, we constructed the multilayer structure of GO and SPES on the polyester tiber mats via layer-by-layer self-assembly. In each self-assembled layer, sulfonic acid groups are arranged along the a^s of fiber, which provides the long-range proton transmission channels, promoting the rapidly proton conduction. The performances of the composite membranes based on SPES and multilayer assembled polyester fiber mats were studied. The results show that the proton conductivity of composite membranes increases with the increasing assembly layers. At the same time, the mechanical properties and methanol-resistance of the composite membranes were obviously improved.

The removal of surface oligomers from polyester fiber was investigated by an Ultrasonic / Alkali System. Effects of concentration of alkali, temperature, time and ultrasonic frequency were discussed. It was found tbat Ultrasonic / Alkali System could decrease remarkably surface oligomers content of polyester fiber dyed by HIP without influencing the dyeing properties of the fiber.

A long-term pilot-scale H_(2)-based membrane biofilm reactor(MBfR)was tested for removal of nitrate from actual groundwater.A key feature of this secondgeneration pilot MBfR is that it employed lower cost polyester hollow fibers and still achieved high loading *** steady-state maximum nitrate surface loading at which the effluent nitrate and nitrite concentrations were below the Maximum Contaminant Level(MCL)was at least 5.9 g·N·(m^(2)·d)^(–1),which corresponds to a maximum volumetric loading of at least 7.7 kg·N·(m^(3)·d)^(–1).The steady-state maximum nitrate surface area loading was higher than the highest nitrate surface loading reported in the firstgeneration MBfRs using composite fibers(2.6 g·N·(m^(2)·d)^(–1)).This work also evaluated the H_(2)-utilization efficiency in *** measured H_(2)supply rate was only slightly higher than the stoichiometric H_(2)-utilization ***,H_(2)utilization was controlled by diffusion and was close to 100%efficiency,as long as biofilm accumulated on the polyester-fiber surface and the fibers had no leaks.

Sea-island type polyester/polyamide composite fiber, in which the island ingredients is polyester, and the sea ingredients is polyamide, refers to using sea-island type composite spinning technology to form the high back elastic fibers, the sea-island type composite fibers have the advantages of both polyester and polyamide fibers, and the material cost is one third lower than that of pure polyamide. In this paper, these performances of the strength and elongation, acid and alkali properties, moisture regain, and specific resistance were tested for the pure polyamide fiber, pure polyester fiber and six kinds of polyester/polyamide composite fiber. The fabrics of the same structural parameters were developed, and the basic properties of the fabric were tested and compared. The results show that with the increasing of polyamide content, the acid resistance and moisture absorption is greatly improved, and the appropriate reducing of the number of islands is helpful to improve the fiber strength, and the fabrics have better rigid-flexibility, creasing recovery and dyeability. If the number of islands is reduced, dyeing properties become better, and under the same denier of material, with the increase of the single-fiber number, the fabric dyeing properties become worse.
