Textile Science and Engineering, volume 48, issue 6, 2011, Pages 331~339
Red wine has become very popular, in part for its professed health benefits. Anthocyanin pigments, which are the main components of the pigments in red wine, are changed in the molecular structures and the color with the solution having different alkalinity and metals. The color changes of a red wine soiled cloth after washing in various pHs and water hardness solutions were studied. Distilled and tap water, which have lower water hardness, showed the highest
value and lowest
values at pH 9. The detergent with added oxygen bleach was more effective in removing red wine soil, even though its pH was 10.8. The effect of the red wine removal with the solution where bleach was added separately was much lower than with the solution of the detergent containing bleach. Water hardness greatly affected the color of the cloth, soiled with red wine after washing. That is, the color was the faintest when the cloth was washed with the bleach-added detergent solution having 0 ppm of water hardness. An effective and economical method or equipment for removing metals in a washing solution for a washing machine should be developed to enhance the stain and soil removal.

Nylon 6-ran-nylon 4 (100/0), (80/20), (70/30) films were prepared by using melt pressing methods. The (N6- ran-N4) films were annealed in the silicon oil bath at 50, 75, 100, 125 and
. The film properties were examined by WAXD, DSC, DMTA and moisture regain. The crystal structure in (N6-ran-N4) films increases the annealing temperature. This is very similar to the alpha phase of nylon 6. The thermal property of (N6-ran-N4) films annealed under high temperature exhibits an increase in the melting temperature and enthalpy. The moisture regain of (N6-ran-N4) films decreased when the annealing temperature was increased.

Dispersion polymerization of styrene was performed in the presence of poly(N-vinylpyrrolidone)(PVP) with the photoiniferter groups as the stabilizer under UV radiation. Poly(N-vinylpyrrolidone-co-4-vinylbenzyl chloride) [P(VP-co-VBC)] was first synthesized by a free radical polymerization. The VBC units were then, modified to dithiobenzoate and diethyldithiocarbamate as the photoiniferter groups. The contents of the photoiniferter groups were 1.7, 2,4 and 4.2 mol%. Polystyrene(PSt) particles prepared using PVP stabilizers with dithiobenzoate groups(PVPDTB) had a spherical shape. On the other hand, PSt particles obtained using PVP stabilizers with diethyldithiocarbamate groups(PVP-DTC) showed a crumpled appearance. The mean diameters of the PSt particles decreased with increase in the contents of photoiniferter groups in the PVP stabilizers. Nano-sized PSt particles(80-90 nm) could be synthesized by using PVP-DTB. PSt particles prepared using PVP-DTC had a crosslinked structure.

Kang, In-Sook ;
Textile Science and Engineering, volume 48, issue 6, 2011, Pages 355~363
The effect of surface morphology of poly(ethylene terephthalate) (PET) film on the detergency of particulate soil was investigated as functions of surfactant concentration, ionic strength, electrolytes type, washing time and particle size. The PET surface film was modified with NaOH and dimethylformamide (DMF) for different times. Generally, the removal of particles from the PET film treated with NaOH and DMF was relatively higher than that of nontreated film in both nonyl-phenol polyoxyethylene ether and sodium dodecyl-benzene sulfonate solution. The removal of particles from the film increased with increasing concentration of surfactant and ionic strength regardless of treated condition, but the effects of electrolytes type, washing time and particle size on the removal of particle from the PET film varied with treated condition such as chemical type (NaOH or DMF) and treatment time. The removal of
particles from the PET film treated with NaOH and DMF were better related with surface energies than surface roughness and surface area. The correlation coefficient between the removal of particle from the film and adsorption of surfactants to film was 0.9.

The effects of annealing on the physical properties of poly(1-oxotrimethylene) (POTM) fibers were investigated in terms of draw ratio (DR). Annealing increased the degree of orientation with increasing DR. Analysis of wide angle X-ray diffraction patterns and Raman spectra suggested that annealing caused crystal structure transition from the
-form to the
-form, which had a denser and more perfect crystal structure. The
-form crystals were favorably formed for as-spun fibers and DR 13 fibers, respectively. In the fiber of DR 4, a combination of both
-form crystals was observed. Once the fiber was melted, no melt crystallization took place during cooling. Infrared spectra revealed that the melting process changed the chemical composition of POTM fibers by thermal decomposition, resulting in disappearance of the melt crystallization. In the stress-strain (SS) curve, the as-spun fibers exhibited yield behavior and a plateau region, while the drawn fibers gave a typical SS curve of brittle material without a plateau region. POTM fibers of DR 13 exhibited a significant increase in tensile modulus compared with as-spun and DR 4 fibers.

This study reports on the output linear density that was attained by simulation for various levels of draft roller gauge and draft ratio, based on the dynamic model with approximated sinusoidal velocity variance model to specific fiber length distributions to test the model feasibility, while a random variation for the input bundle linear density was provided. Results from model simulation showed that a process resonance could take place, when the draft roller gauge or draft ratio reached the critical values, because there were fundamental frequencies which spread in the irregularity of the bundle linear density, giving rise to some resonance. Thus, the irregularity of the output linear density began increasing steeply. From the view point of the output linear density as a whole, the irregularity decreased, as the draft roller gauge increased. A process resonance occurred in the range of draft roller gauge between 1.25 and 1.5 multitudes of the (maximal) fiber length. Length distribution led to a lower fundamental frequency (longer fundamental wavelength) than the uniform fiber length. High draft ratio yielded high irregularity in the output bundle. Especially, the process resonance occurred between the draft ratio 20 and 30. In the draft ratio range higher than 30, the output included wide-ranged regularly oscillatory components of irregularity that corresponded to the integer-multiple of the fundamental frequency, which shifted to a higher value, when the fiber length was distributed. In addition, the approximated sinusoidal velocity variance model turned out to be adequate to estimate the irregularity of the bundle linear density with both the uniform and the quadratic fiber length distribution.

To develop memory foams for the insole of shoes. In order to examine the effect that the types of foam plays on compression set, shape memory characteristics commercial EVA foams and shape memory foams were produced. Cross-linking agents are used in the production of the shape memory foam. The effects that the types of crosslinking agents have on the shape memory characteristics. Shape memory foams appeared to have excellent shape recovery property. They experienced less plastic deformation to compression than the regular foams. Therefore, shape memory foam proved to be more suited for the insole of shoes than the commercial EVA foam. As the percentage of sulfur increased in the cross-linking agent that is used in the production of the shape memory foam, the shape memory characteristic also improved significantly.

In the study, the sorption behaviors of three different cellulose fibers were investigated using heavy metal solutions(Pb(II) and Cd(II)). The sorption dose during the adsorption and desorption was measured using an inductively coupled plasma spectrometer. The initial sorption by cotton was greater than that of the other fibers, while the total adsorption dose of rayon was larger than that of the others. The desorption dose of heavy metal ions from the fiber was negligibly small, indicating that the ions are very strongly physic-ochemically attached to the fiber.

Textile Science and Engineering, volume 48, issue 6, 2011, Pages 393~399
Friction is an important characteristic of the technical yarn. An understanding of this phenomenon is essential for controlling the properties of yarn in a manufacturing process. In order, to evaluate its wear behavior, the mechanical property and the friction coefficient of the yarn used in the seat belt fabric were measured. Different types of technical polyethylene terephthalate(PET) yarns were prepared by varying the yarn denier and the diameter of constituent filaments in the yarn (commonly used as denier per filament or DPF). This was done using a conventional spin-draw melt spinning machine. The yarn of a low DPF showed a higher friction coefficient than that of a high DPF. In a wear test of yarn-to-metal, the low denier yarns lost less strength than high denier yarns. To enhance the wear performance of the seat belt fabric on the basis of the yarn property, the mechanical strength and the wear property of the yarn were coincidently evaluated. As the strength of the seat belt fabric was estimated by using the results of the strength retention ratio after the wear test, a yarn type may be optimally suggested for better wear performance of the seat belt fabric.

Atmospheric plasma(AP) treatment is widely employed to modify the surface properties of polymers. Physicochemical surface properties, such as etching, grafting, polymerization, and cross-linking can be obtained through this treatment using an environmentally -friendly dry process, without altering the polymer inner property. Digital textile printing(DTP) is considered a very efficient textile printing system that, conducts a computing process from pattern design to printing. To obtain good DTP results, the fabric needs pre-treatment to prevent the ink from spreading during printing. In this study, the possibility of using of the AP treatment instead of the usual media treatment for enhancing the effect of DTP on cotton was studied. The results confirmed that the half time is shorted by wave and AP treatment, which measure half time by generating voltage radicals. Absorption height between untreated and AP-treated sample showed 7 mm height differences at 1 kW with 3 times and increased absorption. Inevitably, no physical change by scanning electron microscopy was observed. The color development, sharp were improved after AP plasma.
