Effect of Tyrosinase and Polyphenol Compounds on Hydrogelation of Silk Fibroin
Park, Ji-Hun ; Jeong, Lim ; Park, Won-Ho ;
Textile Science and Engineering, volume 46, issue 2, 2009, Pages 55~61
The formation of silk fibroin (SF) hydrogel can be adjusted by changing physical conditions such as concentration of SF aqueous solution, temperature, pH and salts. In this study, tyrosinase (Tyr), which is an enzyme catalyzing the oxidation of phenols such as tyrosine, was used to decrease the gelation time of SF aqueous solution under a fixed conditions. Tyr oxidizes a broad range of phenols into very reactive o-quinones, and consequently quinones undergo non-enzymatic reactions with various nucleophiles. So it is expected that the gelation time of SF aqueous solution could be decreased by polyphenol compound such as caffeic acid and chlorogenic acid. The color of SF aqueous solutions containing Tyr was changed into deeper yellow with Tyr concentration, and also the gelation time of SF aqueous solution slightly decreased. However, the effect of Tyr concentration on gelation time of SF aqueous solution was not significant due to the locational hindrance of tyrosyl residues in SF. Absorbance at 550 nm also showed conformational transition (random coil to
-sheet conformation) of SF structure. When polyphenol compounds were added into SF/Tyr aqueous solution, the gelation time slightly decreased. However, the phase separation occurred when polyphenol compounds more than 5 mM were added. The results obtained in this study indicate that enzyme and additives have a potential to regulate the gelation behavior of SF aqueous solution, to some extent.

PCL fiber web was fabricated through solution/melt electrospinning of PCL resin. PCL nanofibers were obtained by solution electrospinning of 10.5 wt% PCL solution and the resulting average fiber diameters were varied with the range of 150-500 nm. Melt electrospinning method has the advantage of solvent-free process and it is more eco-friendly than solution electrospinning process. The relationship between processing conditions and fiber morphologies of melt electrospun fibers was investigated and it was found that the temperature in the syringe and flow rate were the main factors in determining the average fiber diameter. In addition, thermal properties of PCL fibers obtained by solution/melt electrospinning were compared with PCL chip.

Antimicrobial acitivity of chitosan fiber was reinforced by N-halamine which is a compound containing nitrogen-chlorine covalent bond that is formed by halogenation of amine in chitosan. Upon pH and chlorination time of sodium hypochlorite solution, aminogroup in chitosan fiber was differnetly chlorinated according to respective conditions. The chlorination of chitosan fiber was confirmed by iodometric titration. The results obtained are following: longer reaction time caused the chlorination of chitosan fibers to increase, and acidic conditions during the treatemnt was more effective compared to alkaline or neutral conditions. The chlorinated chitosan fibers showed powerful antimicrobial activity against both E. coli and S. aureus. SEM observations demonstrated that the chlorinated chitosan fibers were not damaged under the acidic treatment condition.

Textile Science and Engineering, volume 46, issue 2, 2009, Pages 74~82
The purpose of this study was to investigate the effects of ultraviolet (UV) treatment on the hydrophilic properties and removal of particulate soils from microfiber fabrics. A nylon/polyester microfiber knit fabric was irradiated by UV with different treatment times upto 90 min. The hydrophilic properties such as sediment time and contact angle were increased gradually with increase of UV treatment time. However, wicking and water adsorption rate decreased with increase in UV treatment time, which resulted in damage of capillary channel on fabrics. UV treated and untreated fabrics were soiled with carbon black and washed by Launder-O-meter at
with 40 rpm. In order to assess degree of soil removal, following analysis was carried out to remove soils on the fabrics: surface reflectance, K/S was measured to quantify the amount of remaining carbon black and
. The deposition behavior of carbon black on UV treated/untreated fabrics has been also investigated. The soils were more efficiently removed with the increase of UV treatment time.

The purpose of this study is to determine the effect of chitosan treatment on the bamboo charcoal dyed cotton knit. The K/S, CIE
and Munsell values of dyed and chitosan treated samples were measured. As chitosan treatment concentration increased, dye uptake decreased progressively. The chitosan treated cotton knit showed a red tone and a yellow tone on the Munsell color system. The antibacterial property, deodorization performance, moisture regain, thermal transmittance property were improved by chitosan treatment. The bamboo charcoal dyed and chitosan treated cotton knit showed high colorfastness to dry cleaning and washing.
Effects of Chemical Characteristics of Oily Soil on Detergency of Particulate Soil in Oily/Particulate Mixed Soil System -Dispersion Stability of Particulate Soil and Emulsification Stability of Oily Soil-
Kang, In-Sook ;
Textile Science and Engineering, volume 46, issue 2, 2009, Pages 90~97
This study was a preliminary examination on the interactions between chemical characteristics of oily soil and detergency of particulate soil in oily/particulate mixed soil system, which enable to understand the detergent process of particulate soil in interfacial chemical aspect. The dispersion stability of particle increased with oily soil in colloidal dispersion, and decreased with increasing amount of oily soil and decreasing surfactant concentration, but the influence of polarity of oily soil on dispersion stability was low. And emulsification power of polar oily soil was higher than those of nonpolar oily soil, and increased with decreasing amount of oily soil and increasing surfactant concentration. This results showed that chemical characteristics of oily soil such as polarity effect of oily soil exerts on emulsification power than the dispersion stability. But the trend of dispersion stability of particle are similar to emulsification power of oily soil.

Electrospinning is one of the simplest methods for nanofiber fabrication. To investigate the effect of spinning solution conductivity on the spinning behavior and the web morphology, PEO was dissolved in two different solvents,
and ethanol. Also the conductivity of the PEO/water solution was controlled by adding NaCl. The study revealed that the spinnability became poor as the NaCl concentration increased when the applied voltage was lower than a certain level. However, the variance and the average of the fiber diameter decreased with the concentration. As the conductivity increased, the jet movement became more complex.

This study shows the thermal and moisture transfer properties of fabrics used in protective clothing for welders. The purpose of this study is to compare the performance of several fabrics used in protective clothing for welders by transfer test. The moisture transfer was affected by density and thickness of the materials. To improve emissions of water vapor, materials of lower density are suited for protective clothing. The air permeability was affected by coating agents. Silica coating has no effect on permeability of sample. On the other hand, aluminum coating has a bad influence on permeability. To improve air permeability, aluminum coated materials are not suited for protective clothing. Thermal characteristics of the materials were affected by density of the materials. Coated samples have high values of
is warmth and coolness at instantaneous contact sense. If
shows high values, people feel cool skin sensation. The space of water and air makes the sample to have low values of heat transfer. To improve the effect of insulation, felt materials are suited for protective clothing. Felt materials are good heat blocker due to their high air contents.

The digital textile printing (DTP) has several advantages such as proper system for production of small amount, quick response system (QRS), and manufacturing of textile goods by various printing designs. However, it still has problems of color reproduction and control. Generally, color gamut of RGB (red, green, blue) system is wider than that of CMYK (cyan, magenta, yellow, black); therefore, the colors seen in the monitor is different from the colors that appear in the printed output. The color management system (CMS) has been used for improving reproduction and control of printing color. This study was investigated the effects on the appearance of colors in printouts through CMS application such as color gamut, printability and color difference. The results were obtained as follows: first, Color gamut volume with dot gain 49% was decreased to 31.1% in comparison with dot gain 10%; Second, K/S value increased as the dot gain increased; third, the resolution of printer does not have so much effect on printability with light color when dot gain 10 and 20%; and fourth, by using CMS including calibration and profiling process, it was possible to reproduce monitor's color with DTP and reduce the standard deviation of
E between monitor's color and printed color with DTP from 5.27 to 2.92.
