Theoretical Analysis of Fluid Transfer Properties of Fibers of Different Cross-sectional Shapes in Fibrous Assemblies
Hong, Cheol Jae ;
Textile Science and Engineering, volume 51, issue 1, 2014, Pages 1~6
DOI : 10.12772/TSE.2014.51.001
The cross-sectional shape of a fiber has an effect on the comfort-related fluid transfer properties of a fabric, such as wicking, moisture transfer, and tactile properties. For analysis of these properties via simulation, an equation for the hydraulic pore size was derived on the basis of a structural model. The major variables considered in the equation were the fiber shape factor, the fiber fineness, and the mass density of the fibrous assemblies. Using the pore size from the equation, the permeability and the capillary pressure were calculated and then the horizontal and vertical wicking behaviors, i.e., time dependent activity, were simulated. The results show that the equation can be used to quantitatively analyze the fluid transfer properties in terms of the fiber shape factor, which can provide useful information in designing a fiber structure for improving comfort properties.

Microstructural changes of potato and corn starch aqueous solutions associated with their gelatinization and retrogradation processes were examined through the use of small- and wide-angle X-ray scattering. It was found that the structural changes during these two processes were dominantly affected by the amount of phospholipids and phosphates contained in the starch. The phosphates contained in the amylopectin of the starch granule allow easy penetration of water into the structure, thus causing easy swelling or high solubility. This simultaneously allows greater freedom of chains, thus causing the recrystallization of the chains during the retrogradation process. On the other hand, in corn starch, which contains a lower amount of phosphates and a complex structure formed between phospholipid and amylose, the chain movements are much reduced, resulting in a higher gelatinization temperature and a reduction of recrystallization during retrogradation and a broad distribution of crystal size. In both starches, a micro-phase separated inhomogeneous structure was suggested in the amorphous state above the gelatinization temperature, which appears to be associated with the presence of highly branched amylopectin units.

In this study, a coaxial air-blown spinning system has been optimized for the variables of air flow rate, solution concentration, and voltage using the design of experiment (DOE) method. Both response surface analysis (RSA) and Taguchi`s method (TM) were employed and compared to obtain the optimal process conditions. A total of 41 spinning trials were utilized and fitted with RSA and TM; they were then used to obtain mathematical prediction models. The resulting optimum parameters were an air flow rate of 20 l/min, a concentration of 8 wt%, and a voltage of 35 kV, predicting an average diameter of 335.76 nm with an estimated error of 18.85 nm. In TM, the SN ratio was calculated on randomly chosen data. The optimal process conditions that gave the largest SN ratio were an air flow rate of 20 l/min, a concentration of 8 wt%, and a voltage of 30 kV, representing the estimated SN ratio and diameter, -52.03 and 309.11 nm, respectively. For coaxial air-blown electrospinning under the same conditions, the experimental SN ratio and diameter were -52.0269 and 376.75 nm, respectively.

In this study, an epoxy (bisphenol-A type) was selected as a reactive compatibilizer for enhancing the compatibility of immiscible blends of polyamide6(PA6) and poly(ethylene terephthalate)(PET). These blends possess highly desirable qualities, such as low cost and increased moisture absorption, and can be used to construct practical polymer alloys. Using epoxy as a reactive compatibilizing agent, the compatible blends of PA6/PET/epoxy were successfully prepared through melt compounding using a twin-screw extruder. The domain size of PET decreased by a factor of two in the PA6 matrix with the epoxy. The effect of the epoxy on the melt viscosity, crystallization, and tensile properties of the blends indicates that the high-molecular weight epoxy can be an effective compatibilizer in PA6/PET blends.

A series of anionic copolyester/dodecylbenzenesulfonate (DBS) blend films were prepared by a melt-compounding method and then annealed under a range of conditions. To eliminate possible experimental errors in measuring the alkaline reduction rate of the samples, the crystallinity should be uniform. We used Fourier transform infrared (FT-IR) spectroscopy to measure and control the relative crystallinity of the annealed samples. The relationship between the crystallinity and reduction rate, as well as the annealing conditions of the annealed blend samples, was derived. FT-IR analysis showed that the crystallization rate of copolyester/DBS blend films is lower than that of pure copolyester. However, the alkaline weight reduction rate of the blend films, which have similar crystallinities, increases dramatically with increasing DBS content, even at a low DBS content of 1 to 3 wt%, although the effect of the DBS becomes negligible above 5 wt%. However, unlike the result for annealed films, the alkaline weight reduction rate for amorphous films exhibited a linear relationship between the alkaline reduction rate and the DBS content for all of the examined DBS content, demonstrating that the effects of the DBS on the alkaline weight reduction of the copolysester could be affected by processing conditions such as post-drawing and annealing.

The weight reduction and dyeing properties of circular-knitted fabric manufactured from sea-island-type polyethylene terephthalate (PET) ultramicrofiber were investigated. The diameter of a single fiber was approximately 600 nm. The results of scanning electron microscopy (SEM) analysis, alkali dissolution ratio measurements, and cationic dye staining method revealed that the dissolution of the sea component from each ultramicrofiber was completed through alkali treatment with 1% NaOH aqueous solution for 30-40 min at
. The color yield of the disperse dye on the fabric was observed to be dependent on the dyeing temperature. The color yield increased with an increase in the dyeing temperature up to
, and then decreased at
. The build-up property was generally good. The wash fastness was poor and the light fastness was very poor.

In this study, the insecticidal effect of the ethanol extract of Areca catechu against the house dust mite, Dermtophagoides pteronysinus, was examined. Ethanolic Areca catechu extract was directly applied at different concentrations (1.0, 0.5, 0.25, 0.125, 0.0625 mg/
) and then allowed an exposure of 24 hours. The 1.0 mg/
and 0.5 mg/
concentrations of Areca catechu ethanol extract produced mortality rates of 100% and 98%, respectively, against house dust mite, Dermtophagoides pteronysinus. Areca catechu ethanol extract at a concentration of 0.125 mg/
produced a 50% insecticidal effect. These results proved the insecticidal effect of Areca catechu ethanol extract against house dust mite, Dermtophagoides pteronysinus. To check for the presence of the recognized insecticidal arecoline and monoterpene compounds in Areca catechu, gas chromatography-mass spectrometry and thermal desorption-gas chromatography/mass spectrometry were performed. As a result, arecoline and ten monoterpene compounds were identified in Areca catechu.

There is a strong demand for original color reproduction regardless of the imaging device being used. To reduce color distortion and the problem of color communication, it is necessary to determine the color characteristics of each imaging device. For example, color reproduction varies between different kinds of printers because of the differences between the inks and color gamut of each device. It is well known that the ICC profile is used for printer color reproduction. This raises the issue, however, of whether the inks are manufactured using the same ICC profile. In this study, a new digital color device characterization method based on color matching using the R, G, B spectra and C, M, Y, K spectra is proposed. The ICC profile and the multiple regression analysis method are used to compare the results obtained with the characterization method. The differences between the target colors and the colors actually produced by a digital color device, for example, a monitor and a printer, using the proposed characterization method were found to be smaller than when using ICC profiles or the multiple regression analysis method when a comparison is made without considering the color mapping effect. The colors for which there is a large color difference are distributed toward the boundaries of the device`s color gamuts.
