To improve the physical properties of recycled polyester chips, virgin PET chips were compounded with the ratio of 20 wt%, 40 wt%, and 70 wt%. Recycled PET chips blended with virgin PET chips exhibited decreased molecular weights and intrinsic viscosities compared with 100% recycled PET chips and virgin PET chips, and this was caused by thermal and hydrolytic decomposition. End-group contents and MFI both increased in the blended PET chips. As the virgin PET chip contents increased in the recycled PET chips, the melting temperature tended to increase. Recycled PET chips exhibited a higher crystallization temperature compared with virgin PET chips. Morphologies of recycled PET films were analyzed by scanning electron microscopy (SEM). Yellowing of recycled PET chips resulted from intramolecular cross-linking and oxidation reactions. As virgin PET chips were compounded with recycled PET chips, yellowing was reduced. The ash contents were increased in the recycled PET chips which were blended with virgin PET chips. As recycled PET chip contents were similar to those of virgin PET chips, the ash contents were the highest in the experimental materials.

Selected standard methods for washing machines: agitating type; horizontal drum type. Market detergents: standard powder detergent; powder detergent; liquid detergents. Standard soiled clothes composed of five types, including the various contaminants from the actual life of soiled clothes, respectively. When washing with the standard course for a washing machine and using the standard, recommended amount of detergent product, the detergency for the agitating-type washing machine and standard soiled clothes increased by approximately 25%, on average, compared to the case of -30% use, and increased by 2% compared to the case of +60% use, respectively. When the horizontal drum-type washing machine was used, detergency increased by approximately 28%, on average, compared to -30% use, and increased by 12% compared to +100% case. Accordingly, the detergency when using the standard amount of detergent increased by approximately 27% on average, and increased by approximately 7% compared to the cases of +60%~+100% use. Moreover, the residue of the detergent components was extremely small, but proportional nonetheless to detergent concentration.

Nylon 6(N6) and nylon 6(80)-ran-nylon 4(20) (N6-ran-N4) films were prepared using melt pressing methods. The N6-ran-N4 films were drawn uniaxially at various drawing speeds at
, and the film properties were examined by WAXD, DSC, and DMTA. The crystal structure in the N6-ran-N4 films as the drawing speed increased became very similar to the alpha phase of N6. The thermal property of the N6-ran-N4 films prepared with increasing drawing speeds indicated an increasing melting temperature and enthalpy.

Polyacrylonitrile (PAN) homopolymer was hydrolyzed by NaOH to a limited extent. Alkali hydrolysis was carried in a homogeneous solution state and heterogeneous aqueous dispersion state. The PAN homopolymer was dissolved into NaSCN and
solutions, respectively. The carboxylic groups were introduced by hydrolysis of the nitrile groups within the PAN homopolymer main chain. The introduced carboxylic groups lowered the exothermic temperature and the heat of reaction. As the NaOH concentration increased, the exotherm maxima and heat of reaction decreased. Therefore, the fibers from the alkaline-hydrolyzed PAN possess potential for use in simple preparation of carbon fiber precursors.

inorganic nanofibers, TiP/PVAc solutions were electrospun and calcined. Their microscopic structures and morphologies were characterized using FT-IR, WAXD, and SCM. The effects of the spinning and the calcination conditions on crystal formation and structure were then studied. Also, the specific surface area and the photocatalytic activity of the inorganic fibers wcre examined. The Study revealed that fibers with anatase structure showed higher specific sur/ace area and better photocatalytic activity than fibers with a rutile structure.

In this study, we prepared organic-inorganic hybrid nanoparticies with a core-shell structure using a surface-initiated polymerization technique. Initiators for the atom transfer radical polymerization were anchored onto the surface of silica nanoparticies, and from there N-isopropylacrylamide and methylene bisacrylamide were polymerized to form cross-linked polymeric shell layers. The thickness of the polymer layers was controlled by varying the reaction time. The thermal phase transition of the surface polymer layer was characterized by dynamic light scattering analysis, which showed reversible swelling/deswelling behavior between
. Compared to the silica nanoparticies with linear polymer layers, the swelling/deswelling behavior was of a smaller degree, but it consistently exhibited similar size changes after repeated processes. HF etching of the silica nanoparticies with surface cross-linked polymer layers removed the silica core to render a hollow structure.

The effect of heat setting and subsequent dyeing on the mechanical properties of poly(lactic acid)(PLA) fabrics was investigated, including the amount of pilling and "Year resistance. The PLA fabric exhibits significantly reduced tear strength as well as pilling and wear resistance as the heat setting temperature and time increase. While the tensile strength decreased above a setting temperature of
, surprisingly the tensile strength of the set PLA fabric did increase slightly as the setting temperature was increased to values below
, After dyeing, the other mechanical properties, pilling, and wear resistance of the PLA fabrics exhibited similar behaviors to the heat setting treatment. From these results, the heat treatment conditions of PLA fabric should be carefully decided to avoid the deteriorating effects on PLA fabrics.

Flame retarding high impact polystyrene (HIPS) with a reduced amount of halogen flame retardant was prepared by using phosphoric and inorganic flame retardants to improve the shortcomings of the halogen-containing counterparts, such as emission of poisonous gas and environmental pollution. Red phosphorous and metallic flame-retardants were applied for this purpose. Effects of these non-halogen type flame retardants on the thermal and mechanical properties, as well as flame retardancy, of the flame retarding HIPS were examined by thermogravimetric analysis, differential scanning calorimetry, Izod impact strength, and the UL94 flame retardation test.
