The objective of this study was to investigate and to identify and to classify the fabric names concerning costume in the sumptuary laws of Silla in Sam Guk Sa Ki(三國史記). The important findings of this study can be summarized as follows: Various names of fabrics concerning costume in the sumptuary laws of Silla were found to be classified into ten categories of fabrics. They were as follows: (1) kye( ), (2) Su(繡), (3) Kum(錦), (4) Ra(羅), (5) Reung(綾), (6) Sa(紗), (7) Si( ), (8) Kyun(絹), (9) Myun Ju(綿紬), (10) Po(布). Ra(羅) in ten categories was the most various. The numbering orders shown above were the orders of degree of valuability and preciousness of the fabrics in Silla. Namely, (1) Kye( ) was the most precious fabric, (2) Su(繡) was the second precious one, (3) Kum(錦) was the third precious one, and so on. It was found that the orders of the degree of preciousness of fabrics were a system for differentiating social class and rank, or sex of the people. It revealed the ordering system of the degree of the preciousness of fabrics of Silla was derived from T'ang dynasty. The system of Silla and T'ang system were almost the same each other. Materials used to manufacture fabrics were of mainly three kinds; e.g., wool, silk, and hemp. In these three kinds of materials silk was the most common stuff, and it was seen under the various names of the silks.

Effect of disperse dyeing on flame retardant finishing of PET fabrics via UV curing using three UV curable phosphorous-containing methacrylates and ammonium polyphosphate(APP) was investigated. The dye fixation and flame retardancy of PET fabrics did not change significantly with excellent durability to five laundering cycles irrespective of the dyeing and finishing sequence. However, the flame retardancy of Pekoflam-treated fabrics was lower than that of the UV treated and decreased substantially when heat treatment was carried out before the dyeing. The dyeability of the flame-retardant PET fabrics was not affected in the case of UV curing of the methacrylates alone. However, UV finishing after the dyeing caused significant decrease in K/S and ${\Delta}E$ due to changed refraction and inherent color of surface coating of the UV curable monomers and APP. Whereas the heat treatment with Pekoflam decreased both color fastness to laundering and sublimation, surprisingly the UV finish of PET fabrics before and after the dyeing increased the color fastness probably resulting from the presence of photopolymerized surface layer on the fabrics.

This study investigated the effect of water absorption on the tensile properties of carbon-glass/epoxy hybrid composites at room temperature and $-30^{\circ}C$. To investigate the effect of the position of glass fabric in the hybrid composite on the tensile properties, the stacking pattern of the fiber fabrics for reinforcing was created in three different ways: (a) glass fabrics sandwiched between carbon fabrics, (b) carbon fabrics sandwiched between glass fabrics and (c) alternative layers of carbon and glass fabrics. They were manufactured by a vacuum-assisted resin transfer molding (VARTM) process. The results showed that there was surprisingly little difference in tensile strength at the two different temperatures with dry and wet conditions. However, the water absorption into the hybrid system affected the tensile properties of the hybrid composites at RT and $-30^{\circ}C$. When the glass fabrics were at the outermost layers, the hybrid composite had the lowest tensile properties. This is attributed to the fact that the composite had a relatively high water absorption rate.

To develope natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the waste grape juice. Dyeing experiments were done under different dyeing conditions of dyeing time, dyeing temperature, pH and concentration of dyebath and mordants which were treated after dyeing. Experimental fabrics were silk, cotton, ramie and hemp. Color difference(${\Delta}E$) and Munsell's HV/C of the dyed fabrics and color fastness of silk dyed fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. The color differences of dyed experimental fabrics were very slightly increased with dyeing time and the color of dyed silk was light purple and the cotton, ramie and hemp was light red purple. The color differences of dyed experimental fabrics were decreased and the color became lighter with dyeing temperature increased. The color differences of dyed experimental fabrics were decreased and the color changed from light purple to blue with the pH of dyebath increased. The color differences of dyed experimental fabrics were slightly increased with the concentration of dyebath increased. The color of dyed fabric changed with the mordant treatment and were different among the experimental fabrics. On the whole, blue tone increased with the Al and Fe mordant and green tone increased with the Cu mordant. The color fastness of dyed silk fabrics to light, washing (change) and perspiration (change) was bad and color fastness to dry cleaning and rubbing were good.

The physical characteristics of silk and wool fabrics dyed with OFS-FR and SM-FR were examined and color difference and colorfastness of these fabrics were analyzed. The results are as follows; 1. The thickness, density and weight of both dyed fabrics were increased than those of undyed fabrics independently of dyeing materials and mordants. 2. Air permeability of all the silk samples increased than that of undyed silk, on the other hand, air permeability of most of wool samples decreased than that of undyed wool. 3. Thermal insulation values of silk samples were not consistent with dyeing conditions, but those of wool samples increased than those of undyed fabrics regardless of dyeing materials and mordants. 4. Color difference was clear between OFS-FR and SM-FR dyed fabrics. The colors dyed with OFS-FR-Al and OFS-FR-chitos an showed violet, those dyed with SM-FR displayed yellowish, in addition to in case of wool, dyed with OFS-FR-Cu the color was greenish yellow, in case of silk dyed with SM-FR-Cu that was yellowish red. 5. Sense of silk fabrics by sensory-test was soft and smooth. Feeling of colors in silk fabrics was wick, warm and slightly brilliant. In case wool, sense of dyed fabrics was slightly soft and slightly rough. Feeling of colors in wool fabrics was warm but not elegant. Therefore the result of sensory-test in silk might be better than that of in wool. 6. Colorfastness to dry cleaning and perspirations was good, but that to washing and sunlight was not fine.

This study explores and selects an appropriate material that considers light and soft physical properties as well as activity for impact absorption pads that can be used to develop practical impact protective clothes worn during daily life by the elderly to reduce the impact of falls. Physical properties, impact absorption performance, and compression characteristics were evaluated on 5 types of foam, 2 types of 3D spacer fabric, and 3 types of polymer gel to select a material appropriate for the pad to be inserted into impact protective clothes. The evaluation of the physical properties showed that 3D spacer fabrics had lower density compared to other materials and polymer gels had the highest density. The elongation percentage was higher in foams than 3D spacer fabrics and EPDM foam had the highest elongation percentage. The impact absorption performance of honeycomb polymer gel was better than foams and 3D spacer fabrics. As a result of looking into compression energy and compression characteristics of materials, 'CR foam A' was found to absorb the largest amount of compression energy, 24.1%, among foams and polymer gels. A high energy absorption rate of 50.0% (or above) was indicated by 3D spacer fabrics; however, foams and polymer gels showed a progressive deformation of energy compression / recovery curve with 3D spacer fabrics that showed drastic deformation. Based on characteristics of materials, 'CR foam C' and EPDM with relatively high absorption performance can be used as protective pad materials among foams. Among polymer gels, 2 open-type polymer gels that have relatively low impact protective performance but a relatively lighter weight on human body (compared to closed-type) are considered appropriate protective pad materials.

Cooling function is definitely one of the most desirable attribute of clothing. In spite of the recent progress on phase changing material(PCM) research, the final products with sufficient amount of cooling capability have not yet to be developed in market. A new concept of cooling fabrics has been proposed by applying "Peltier effect" to textile materials. It occurs whenever electrical current flows through two dissimilar conductors; depending on the direction of current flow, the junction of the two conductors is absorbed or released heat. This effect has been tested on P-type and N-type conducting polymers. A P-type conductive polypyrrole coated fabric was synthesized by in-situ polymerization on plain weave PET to make conductive fabrics. And an N-type electrically conductive material was synthesized by treatment of MWNT and polyethyleneimine(PEI). A noticeable amount of temperature difference has been found on the fabrics.

The object of this study was to identify the production technique and immediate constituent of lingerie by examining the materials and the sewing techniques. Various papers are referenced for theoretical study and the elements and techniques of lingerie are analyzed based on photographical materials. From the late 20C century to the present time was the research time period. This paper concludes as follows: 1 Decorative method: Lace, Ribbons, piping, elastic bands were some of the decorative materials attached to the garments by zigzag stitch. 2. Flat pattern making: Lingerie patterns were drafted in smaller size than the patterns of outer garments. Bias cut would be applied for the noll-stretchable fabrics. 3. Draping: Bias grain would be applied for the non-stretch fabric. When draping stretch fabrics, follow the grain line of the fabrics and pull the fabric so that it could fit onto the body. 4. Production technique: Straight stitch would be applied for non-stretch fabrics. Zigzag stitch would be applied for stretch fabrics.

The self-cleaning properties of nano-zinc oxide on cotton fabrics have been investigated. The cotton fabric has been prepared by pad-dry method. The nano-zinc oxide was encapsulated in the polystyrene particle by mini-emulsion process prior used. The loading amount of zinc oxide particles into the mini-emulsion were various from 1% wt to 40%wt. The particles sizes of ZnO-encapsulated polystyrene mini-emulsion were determined using dynamic light scattering. It was showed that the particle size of the mini-emulsion was in the range of 124-205 nm. The topography and morphology of ZnO-encapsulated polystyrene which coated on cotton fabrics was observed using scanning electron microscopy. The crystal structure of ZnO-coated on cotton fabrics was explored by X-ray diffraction spectroscopy. The photocatalytic activities of zinc oxide were present through the self-cleaning properties. The presents of the zinc oxide on cotton fabrics significantly showed the improving of the self-cleaning properties under UV radiation.
