Polyester(PET) fabrics were treated by corona discharge equipment with the small amount of flame retardants to enhance flame retardancy. The surface properties of corona discharged fabrics were investigated using water penetration time, SEM, ESCA, and TGA. When corona discharge was applied to PET fabrics, the flame retardants were evenly distributed. As a result, the oxygen-containing functional groups were produced, and the LOI value increased. Thermogravimetric analysis indicated that the flame retardancy was operative by gas-phase mechanism.

With the advancements in the computer graphics sectors, the visual quality of the virtual clothing implemented by using the 3-dimensional digital clothing software system has been much improved during the past decade. Most of the cloth simulation procedures are complicated due to the multitude of parameters involved in the simulation in order to achieve the appearance of the actual textile fabrics or the movement of the actual clothing as close as possible. Bending properties affect the tactile and visual qualities of the textile fabrics along with the shear and tensile properties. In this study, dynamic bending properties, focused on the movement of the textile fabrics including damping ratio and amplitude, were measured by using a dynamic bending test system.

Dyeability and antimicrobial activity of Saururus chinensis on to silk and cotton fabrics has been studied. The dyestuff was extracted with distilled water. Silk fabric showed higher K/S value than cotton fabric at the same condition. And with the simmordanting by Fe, Cu gave good improvements of the K/S values. Surface color of dyed fabrics was various according to the used mordants: Cr mordanted fabric was to be cleared, Fe mordanted fabric was the greatest color difference. The fastness was significantly improved in mordanting. The Fe, Cu mordanted silk fabrics was the greatest antimicrobial activity.

This study aims at developing of textile design expressed not only Korean natural image but also modern sensibility using fabrics dyed by tie dyeing with various natural dyes. And it attempts to practicality of high value-added goods revived traditional beauty. With the aqueous extract of various natural dyes, i.e., indigo, amur cock tree, onion's peel, citrus peel, mugwort, gromwell, sappan wood silk fabrics dyed by tie dyeing. Also various color changes were examined by mordants, i.e., aluminium sulfate, cupric acetate mono hydrate, ferrous chloride. With these fabrics, I made works using the techniques of applique, mola, fabric's connection and weaving. I think the developed textile design gave expression to natural image of Korean nation.

Wool fabrics were treated with dichloro isocyanuric acid (DCCA) and dyed with acid dyes (C.I. Acid Red 18), and then, they were treated by sputter etching. Wool fabrics had been sputtered with aluminium under various conditions such as sputter etching time and discharge power in the presence of argon gas. We compared mechanical properties, colour difference and fastness properties of these samples one another: Mechanical properties and colour difference of sputtered wool fabrics changed by sputter etching time, discharge power and DCCA concentration. Light fastness showed a rising tendency but rubbing fastness showed a downward tendency when sputter etching time was 7 minutes.

The attractiveness of the textile fabrics are generally judged by visual or tactile evaluation methods. Since the surface of the textile materials are so diverse that the visual factors such as optical properties or luster of the fabrics are not easily measurable. While most of the cotton fabrics are not so much lustrous, calendering process could impart the cotton fabric better luster. Also, the general grade silk-like polyester fabrics resemble silk fabric with some limit in terms of luster properties. One of the interesting fabrics showing subdued luster is the velvet fabrics with dark shade. In this study, the luster related properties are examined using some image analysis methods. Yarn models based on the fabric weave types were developed to further investigate the effect of fabric crimp shapes due to weave on the optical properties or luster of the fabrics.

The physical properties and biodegradability of cellulose fabrics, such as cotton and rayon, are expected to vary with textile care. In this study cotton and rayon fabrics were washed repeatedly with detergents, bleaches, or softeners. The changes of physical properties were investigated by measuring retention of breaking strength, shrinkage, handle, and the fiber surface was observed by SEM. The biodegradability of fabrics was also estimated by soil burial test. The results were as follows. Cotton fabrics laundered repeatedly by detergents and bleaches lost virtually no strength. The breaking strength of the rayon fabrics decreased by about 17%∼25% after repeated launderings. Shrinkage in weft direction was much larger than that in warp direction. Bending rigidities of both fabrics decreased remarkably within 10 wash cycles. Shear rigidity in cotton fabrics increased continuously with repeated washing cycles, however, that in rayon fabrics did not show any change as washing went on. Friction coefficient increased in both fabrics after 10 wash cycles, and this is thought to be attributed to the wrinkle, interlocking of hairs, surface damage resulted from repeated washings. In cotton fabrics made of staple yarns, short hairs on the yarn surface entangled together with repeated launderings. This resulted in the continuous increase in % shrinkage, shear rigidity, friction coefficient. Rayon fabrics made of filament yarns, however, did not show this phenomenon. Softener treated fabrics showed the lowest values in bending rigidity, shear rigidity and friction coefficient because the cationic surfactants adsorbed on the fiber surface behaved like lubricants. The biodegradability of fabrics was noticeably affected by the composition of washing solutions. The fabrics washed with detergents and bleaches were decomposed faster than those washed with the others were and the cotton fabrics washed with detergents and softeners hardly degraded. The fabrics soiled with milk were decomposed almost completely and those soiled with Palmitic acid did not degrade greatly.

This study reported the dual functional self-cleaning PET fabrics prepared from $TiO_2$ and hexadecyltrimethoxysilane treatment, which have photodegradation and superhydrophobicity on the fabric surface. Phodegradation and superhydrophobicity of the resulting fabric were compared with $TiO_2$ or silane treated fabrics. The dual functional self-cleaning PET fabric showed less photodegradation than the $TiO_2$ treated fabric. However, the dual functional self-cleaning fabrics showed superior superhydrophobicity to silane treated fabric with increased water contact angle and significantly decreased roll-off angle. This suggested that the dual functional PET fabric has a great potential to be the commercialized self-cleaning fabric because it is repellent to soil or dust and even if soil or dust is adsorbed on the fabric surface, it can be removed by water rolling off on the surface or photodegradation by the photocatalyst.
