Copolyesters containing sodium sulfonate group and poly(ethylene glycol) (PEG) were synthesized with various molecular weight of PEG. The selected molecular weights of PEG were 1000, 2000, 4000, 6000, and 16000. The thermal properties and the crystallization behaviors of the copolyesters were investigated by using differential scanning calorimeter (DSC). Alkaline hydrolysis of the copolyesters was studied as a function of the treatment time. The melting temperatures and the heats of fusion of the copolyesters increased with an increase in the PEG molecular weight, while the weight reduction rate of copolyesters in an alkaline solution decreased with an increase in the PEG molecular weight. At the same PEG content in copolyesters, hard segment length increases with the PEG molecular weight, which was thought to be the most important factor that determines the thermal properties and the alkaline hydrolysis behavior.

Polyacrylonitrile (PAN) particles synthesized by dispersion/emulsion polymerization of acrylonitrile monomer were cross-linked with hydrazine in order to prevent its dissolution in water when they were subjected to hydrolysis. Hydrazine-crosslinked PAN (cPAN) particles were hydrolyzed with NaOH solution in order to impart them with high hydrophilicity. The effects of the cross-linking degree, i.e., the hydrazine concentration during the cross-linking of PAN, NaOH concentration on the hydrolysis behavior of cPAN particles and their particle shapes were analyzed. Results revealed that cross-linking of PAN with 5% hydrazine solution at
for 3 hours and hydrolysis of cPAN with 5% NaOH solution at
for 3 hours is suitable for the preparation of highly hydrophilic and water-insoluble PAN particles. Then, hydrophilicity and the heat release property of the hydrolyzed, cross-linked PAN (h-cPAN) particles were examined. The h-cPAN particles exhibited a temperature rise of up to
by water absorption and a moisture regain of up to 23% at
and 65% RH, depending on the hydrazine cross-linking and NaOH hydrolysis conditions. Cotton fabrics were treated with h-cPAN dispersion solutions of different concentrations by a normal pad-dry process. The temperature changes of the treated fabrics by water absorption were measured. The h-cPAN treated fabrics showed higher temperature rise by moisture absorption compared to untreated one. It indicates that the particles can be used as a potential moisture-absorbing heat release finishing agent for textiles.

Weight reduction behavior and dyeing properties of sea-island PET ultra-microfiber knitted fabrics were compared to those on the fabrics of the conventional microfiber. In the dissolution of the sea component out of seaisland type nanofilaments, it is important to determine the optimum alkaline treatment time in order to avoid the further damage of island component. SEM micrographs reveal that the dissolution of the sea component of each nanofilament fabric completed after 30 or 40 min at
. Build-up property of disperse dye on sea-island type PET fabric from microfiber or nanofilament was generally good. Color yield of fabric from micro filament was higher than that from the nanofilament. Color yield of the fabric from PET micro- or nano-filament was found out to be dependent upon the dyeing temperature. The color yield decreased as the dyeing temperature increased. Wash fastness was moderate and light fastness was very poor.

In order to provide a fundamental understanding of cloth surface smoothness, the wrinkle components in the AATCC standard replica were studied. Using an image acquisition system with a line light source and a camera, images of the replica were obtained. Four images of each replication were taken at intervals of
degree rotations. The wrinkle ridges in the image were extracted using Canny edge detection, while the shade generated by the wrinkles was obtained using line threshold method. The ridge density, the distribution of ridge-to-ridge distance and the shade length distribution were measured and calculated. The three factors measured showed a strong non-linear relationship with the replication grades.

In this work, effects of total draw ratio change on the mechanical properties of polyester fibers were studied. The process parameter was a total draw ratio and the draw ratios that were used ranged from 6.6 to 7.0. Tensile properties are determined from the tensile tester, and crystallite parameters from the density measurement and X-ray diffraction were discussed with the different total draw ratios. The tenacity, young's modulus and crystallinity were increased to 10.6 g/d, 123.2 g/d and 42.1%, respectively, with increase in the total draw ratio. The relations between total draw ratio and mechanical properties of high tenacity polyester fiber were discussed.

A poly(vinyl alcohol)(PVA)/poly(acrylonitrile)(PAN) blend film was prepared and its properties were characterized to investigate the possibility of improving PVA as a reinforcing materials. From the wide-angle X-ray diffraction patterns of the blend films it can be seen that the diffraction peaks from each polymer's crystal were not changed by blending, this implies there is no mutual influence in crystallization. The water contact angle of the blend film increased with increasing PAN content. The decrease rate of the water contact angle of the blend film with time was smaller than the rate for pure PVA film. The melting temperatures of the PVA/PAN blend film only at the ratios of 99/1 and 97/3 were higher than that of pure PVA film. The thermal decomposition temperature and residual weight of the blend films were increased with increasing PAN content, indicating improved thermal stability after blending with PAN. The tensile strength and Young's modulus of the film increased after blending and the PVA/PAN blend film containing 3wt% of PAN showed the best mechanical properties.

In order to prepare a flexible dry-type electrode for electrocadiogram (ECG), conductive poly(vinylidene fluoride) [PVDF] was electrospun and silver-plated electrolessly. The surface morphology and the mechanical and electrical properties of the silver-plated nanowebs prepared under different plating conditions were evaluated. After silverplating, the prepared web was welded ultrasonically in order to improve the conductivity and the rubbing fastness. Dry-type electrodes were fabricated into eyelet shape by using the ultrasonically welded silver-plated PVDF nanoweb, a sponge and a metal eyelet. Then, it was attached to a commercial sports brassiere top. The ECG of the wearer of the top was measured by the newly developed electrodes and the commercial Ag/AgCl gel electrodes while walking and running. The comparison reveals that the silver-plated PVDF nanowebs can be used as an electrode for ECG measurement.

Two commercial compatibilizers of ethylene glycidyl methacrylate (EGMA) and styrene-b-ethylene/butyleneb-styrene grafted with maleic anhydride (SEBS-g-MA) were added to poly(phenylene sulfide) (PPS)/poly(ethylene terephthalate) (PET) (80/20, weight ratio) and PPS/polyamide 66 (PA66) (80/20, weight ratio) mixture, respectively. This was done by using a twin screw extruder via a melt blending method and the blends of the three components were melt-pressed and quenched to the films of 200
. Changes in thermal, mechanical, chemical and morphological properties of the blend films were analyzed by using DSC, DMA, WAXS, SEM and UTM. DSC results showed that EGMA in PPS(80)/PET(20)/EGMA blends lowered
of PPS. They hindered the crystallization of both PPS and PET. Addition of EGMA imparted partial miscibility to the immiscible PPS(80)/PET(20) blends but the total miscibility and compatibility were not enhanced. Mechanical and chemical properties of PPS80/PET20/EGMA blend films deteriorated more with an increase in EGMA content. SEBS-g-MA did not work as a compatibilizer at all for PPS(80)/PA66(20) blends rather it enduced phase separation of the blends.

The uncrosslinked and crosslinked by ethylene glycol diglycidyl(EGDE) chitosan/sericin blend films were prepared by solvent blending method. Physicochemical properties of the prepared blend films according to various blend ratios were investigated. This was carried out by using universal testing machine, thermogravimeter(TGA), differential scanning calorimeter(DSC), wide angle X-ray diffractometer(WAXD), Fourier transform infrared spectrum(FTIR) and scanning electron microscopy(SEM). With an increase in the sericin mixing ratio, tensile stress increased whereas the tensile strain decreased for uncrosslinking blend films. For a cross linked chitosan/sericin blend film by EGDE, both the tensile stress and strain decreased. Chitosan/sericin blend films exhibit an excellent thermal stability when sericin mixing ratio is 25%. In the infrared spectra, chitosan/sericin blend films showed an absorption band of amide I peak at 1630
and it is concerned with C=O stretching vibration by strong hydrogen-bond between inter-molecular. These also showed an absorption band of amide II peak at 1521
concerned with N-H bending vibration. The absorption band of amide I peak decreased with an increase in the chitosan mixing ratio. We identified that there was good miscibility between chitosan and sericin. The water-retention values(WRV) of chitosan/sericin blend films increase as the amount of sericin is raised and this owes to the hydrophilic nature of sericin. Weight loss of the citosan/sericin blend films by cleaning with an aqueous sodium hydroxide increased with an increase in the sericin mixing ratio. This loss is the loss of acetic acid and sericin in the chitosan/sericin blend films and this is because of the molecular weight of the sericin is 1/5 of the chitosan and sericin is dissolved into NaOH solution. Weight loss increased when sericin content was more than 50% for the cross linked chitosan/sericin blend films. From the structure analysis, we identified that there was good miscibility and strong intermolecular interaction between the chitosan molecules that resulted from intermolecular hydrogen bonds.
