Nowdays, the computational simulation of molecular energy potentials and the empirical evidence using electrochemical reduction/oxidation values are very significant factors to predict of molecule's energy potentials. The prepared chemosensor herein consists of spirolactam ring system in the structure, providing intra-structural change with metal cation binding. In this study, rhodamine 6G-Naphthaldehyde chemosensor was determined and compared with HOMO/LUMO energy levels by computational calculation and cyclic voltammogram method.

The energy levels are very important to investigate properties of organic dye materials. These values of energy levels can be calculated and compared with absorption spectra, cyclic voltammetric measurement and computer simulative calculation. In this study, absorption and emission changes were observed by complexation between rhodamine 6G based dye and mercury. This is related to spirolactam ring system of rhodamine 6G based dye. According to structural change of this dye, HOMO and LUMO energy levels were investigated and determined by their values with different approaches.

DOI : 10.5764/TCF.2013.25.1.18
A water soluble spironaphthoxazine (SPO) was synthesized, and its spectral properties were determined. Under UV irradiation, colorless SPO shows intensive blue color while the intensity of its initial fluorescence decreased. In addition, SPO also exhibited high sensitivity to pH stimuli both in colorimetry and fluorometry distinguishing from the spectral appearance observed under UV irradiation. Further, integrating these two optical characteristics a three-state switching system can be established, and all interconversions can be observed by naked-eye.

DOI : 10.5764/TCF.2013.25.1.25
Poly ketone (PK) was photo-oxidized by UV/ozone irradiation and the effect of UV energy on the surface properties of the UV-irradiated PK film was investigated by the measurement of reflectance, surface roughness, contact angles, ESCA, and ATR. Reflectance, particularly at the wavelength of 380nm, decreased with increasing UV energy. And the irradiation produced nano-scale roughness on the surface uniformly. The maximum surface roughness increased from 25.3nm for the unirradiated sample to 104.9nm at the irradiation of
. The improvement in hydrophilicity was caused by the introduction of polar groups such as C-O and C=O bonds resulting in higher
. The surface energy of PK film increased from
for the unirradiated sample to
at the irradiation of
. The zeta potential of the UV-irradiated PK decreased with increased UV energy and the dyeability to cationic dyes increased accordingly, resulting from the photochemically introduced anionic and dipolar dyeing sites on the PK films surfaces.

Swelling and subsequent deformation of membranes by water wetting are regarded as a prime drawback of hydrophilic polyurethane breathable film. Fluoroalkylated surface was prepared by reacting the film with hexamethylene diisocyanate(HDI) and 2-perfluorohexyl ethanol. IR spectra and XPS results showed that the fluoroalkyl group was successfully introduced to the film surface with hexamethylene linkage. Water contact angle was increased from
with the degree of fluoroalkylation. Decrease in water-vapor permeability was minimized even for the film of highest fluoroalkylation.

This paper surveys the ESD characteristics of the PANI added PU/MWNT film according to the manufacturing conditions such as variation of the loading contents of PANI and the mixture ratio of 2 dispersion solutions. For this purpose, PANI added PU/MWNT ground films were made with IPA/MWNT 3wt% dispersion solution and PANI/DMF dispersion solutions(5, 10, 15, 20, 25, and 30wt% contents of the PANI) by the mixture ratio of dispersion solution(10/50, 20/40, 30/30, 40/20, and 50/10part) in the PU (972DF) 100g, which was treated with 500rpm for 30min in the stirrer with condition of the dry temperature
for 2min. Totally, 36 kinds of PANI added PU/MWNT film specimens were prepared. The physical properties of the PANI added PU/MWNT films such as electrical resistivity, absorbancy by UV-Vis spectrometer, and triboelectricity were measured and discussed with surface characteristics of the PANI added PU/MWNT films by SEM. The dispersion property of PANI to the DMF showed best dispersion at the 25% of PANI content. The surface electrical resistivity of the PANI added PU/MWNT films was decreased with increasing the weight content of PANI/DMF dispersion solution, and it showed the lowest value
at the mixing condition of PANI/DMF 20part and MWNT/IPA 40part with 30% PANI. Furthermore, it was shown that the electrical and physical properties of the PANI added PU/MWNT film such as electrical resistivity, and triboelectricity were better than those of PU/MWNT film prepared with no PANI, which was result obtained in previous paper.

Physical properties of the composite yarn using low-melting(LM) polyester/Tencel were investigated with air-jet texturing conditions such as temperature, take-up overfeed, yarn speed and air pressure. Surface morphology, microstructure, tensile property, glossiness were evaluated. Surface morphology of a composite yarn had more damaged and loosened structure according to increase of take-up overfeed, yarn speed and air pressure. Crystallinity was affected by parameters such as temperature, yarn speed, take-up overfeed and air pressure and especially, yarn speed was most effective for increase of crystallinity. Also, it was found that temperature and air pressure had significantly affected tensile properties of a composite yarn. The glossiness of yarn increased with increase of temperature, yarn speed and air pressure.

In order to examine the availability of color developing for prepared persimmon extract powder dyes, purified and freeze-dried powder from immature persimmon fruit. The cotton fabrics dyed with 1% concentration of powder dyes. This study was conducted to examine into the color developing effects of the powder dye for the dyed cotton fabrics irradiated with xenon light. Powder dye is difficult to dissolve in water resulting in a colloidal and viscous solution. The problem of solubility in water was resolved by setting the dyeing conditions by wetting the dye with alcohol in advance and dissolving in warm water(
). Samples had no alkaline conversion in making process of powder dyes showed high color developing effect(
, K/S). Samples showed decreased
, K/S with increased alkaline conversion in making process of powder dyes. Samples that had alkaline effects displayed easy early color developing to be advantageous in the process of natural pattern in art work.

PET fabrics of various luster, fiber thickness(denier), and weaving structure were dyed at the same conditions and determined their grey scale by using naked eyes, computer color matching (CCM) system, and real industry color (RIC) device to evaluate the effectiveness of RIC device developed in this study. As for the luster of fabrics, bright PET showed more differences when compared with semi-dull and full-dull. PET in both naked eyes and RIC device since the RIC device provide the real image of fabrics to observers. As for the fiber thickness, the results of naked eyes and RIC device were very similar while the result of CCM showed lower color grade. Finally, as for the weaving structures of PET fabrics, all the test results by naked eyes, CCM, and RIC device showed almost same grey scales. In these regards, the RIC device developed in this study was comparable to naked eyes by providing the real image of fabrics, however it was difficult to compare the very bright colors such as yellow and fiber thickness(denier) and weaving structure of fabrics.

For amine gas detection, we incorporated two well-known isomers, 2-chloro-3,5-dinitro-benzotrifluoride and 4-chloro-3,5-dinitro-benzotrifluoride, in polyurethanes. Nanoweb and thin film were prepared by electrospinning and lamination, respectively, in order to compare their sensing behaviors. Moreover, we studied photophysical property using UV-Vis spectrometer and observed surface area through scanning electron microscope to compare between the Nanoweb and thin film. We found out that nanowebs exhibited high sensitivity specifically to primary amine gas.

Colorimetric and wash fastness data after repeated wash cycles of Poly Lactic Acid(PLA) fiber were examined with C. I. Vat Blue 1, also other comparing 2 dyes (C. I. Vat Blue 35, C. I. Vat Blue 5), in this study. The fastness of three vat dyes on PLA fiber to repeated washing according to KS K 0430 A-2 regulation increased with dyeing temperatures. The
values of the dyed material gradually increased with increasing numbers of wash. Also the f(k) values were decreased reversely. During repeated washing, the vagrant dyes were deposited especially on nylon, polyester, cotton of the adjacent multifiber. C. I. Vat Blue 5 displayed lowest color change to repeated washing of the three dyes used.
