  • This research investigated the effect of individual yarn colors on the perception of overall colors of yarn-dyed woven fabrics. The way the colors of yarn-dyed woven fabrics are perceived is known as visual color mixing: when the different colored yarns juxtaposed on the fabric surface are observed from some distance away, they are visually mixed in our eyes and perceived as a solid color. However, we can still see individual yarn colors that make the fabrics look obviously different from actual solid colors. To quantify this visual color mixing effect, twenty-one sateen fabrics were produced in a wide range of colors using cyan, magenta, and yellow yarns, and the colors were measured instrumentally. The obtained colorimetric values were converted into solid color images on a CRT monitor. Then, the physical fabrics were scanned, and the scanned images were displayed on the monitor with solid color images in pairs for visual color difference evaluation. The woven and solid colors in each pair were of physically identical color; however, the visual color difference was as large as $4.81{\Delta}{E^*}_{ab}$ on average. A visual color difference model was proposed by considering this parametric effect of individual yarn colors.

  • Sensorial tests were executed to find the sensibility and texture of the fabrics. The physiological responses employed in this study was electroencephalogram(EEG). The purpose of this study is to find out how the sample groups responded to the texture of the woven silks and the woven ramie. The sample groups are of 10 males and females, age of 25. EEG was recorded a fast and slow alpha wave according to the texture of the textiles. The sample fabrics are of woven silk and woven ramie. The results obtained as be lows. When the sample groups touched the woven silk, they responded and showed more slow alpha wave than the woven ramie. The slow alpha wave raised when the sample groups felt comfort and relax. The fast alpha wave were more in the woven ramie, it raised when the people felt the tension and the anxiety. There was no significant difference between the male and the female. Woven silk has the soft and smoothness it causes comfort. The sensation of tactile was recorded through the EEG.

  • The goal of this research is to investigate the effect of fusible interlinings on the mechanical characteristics and appearance related values for the Lyocell fabrics. In this study, to establish optimum fusing conditions, peel strength of the fused fabrics depending on the fusing temperature, pressure and time was measured. Appearance related properties and mechanical characteristics of the fused fabrics ere determined. The reulst are as follows: In the fusing condition of $120^{\circ}C,\;3kgf/textrm{cm}^2$, 15sec, peel strength was excellent. Peel strength was excellent in the case of tencel/cotton fabric, with increasing cover factor of woven interlining, with twill and nonwoven interlining. Flex stiffness was increased in the case of tencel/cotton fabric, with increasing weight of woven interlining, with twill and nonwoven interlining. Drapability was excellent in the case of 100% tencel fabric, with decreasing weight of woven interlining, with plain and woven interlining. Crease recovery was excellent in the case of 100% tencel fabric, with increasing weight of woven interlining, with twill and woven interlining. Shear and bend properties were increased in the case of tencel/cotton fabric, with increasing weight of woven interlining, with plain and nonwoven interlining.

  • 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.

  • Geotextile effects as reinforcement and vertical drain materials are studied through the laboratory model embankments on weak clays. The experiments are carried out in four stages; no woven fabrics between clay-crushed stone boundary, fabrics between boundary with no initial pretensioning of fabrics, and fabrics between boundary with two different initial pretensionings of fabrics. In all stages, vertical drains utilizing non-woven fabrics are installed in the clay layer in square pattern to accelarate the consolidation. The experimental model has plane dimensions of $32cm{\times}330cm$. The height for the clay container is 60 cm. The 47 cm height of crushed stone embankment is constructed over the 50 cm deep clay layer. The time dependent pore pressures are measured utilizing the 8 piezometers installed symmetrically on both sides of the wall at different heights. The time dependent deformations are measured utilizing the LED indicating lamp matrix inserted in the crushed stone embankment and the dialgauges put on top of the clay layer where the crushed stones are not laid. The measurements are carried out for 10 days which is equivalent to the time required for the primary consolidation. Through the experimental study, an analytical procedure is developed to predict the time dependent embankment settlement even if the top of the clay layer is reinforced with woven fabrics. This can be done through measuring the maximum pore pressures developed in the clay layer and comparing with the theoretical maximum pore pressures when no reinforcing fabrics are employed.

  • The kind and the use of the fabrics for crown manufacture in the Baekje period has been studied by characterizing the imprinted fabrics on the crowns and the diadem ornaments from the old tomb. The contact region with the skin inside of the crown and the region between the bark of white birch and the gilt bronze openwork plates contained fabrics. The fabrics used in the gilt-bronze crown were all plain weave silk except that of Yongwonri tomb where loosely woven thin tabby was used. There have been 4-types of iron framed diadem of the Baekje, which comprise the inverted triangle-shaped diadem only with iron frame, the diadem with gold plate ornament in the iron frame, the diadem decorated with mica plate and gold plate, and the diadem with silver ornament in the iron frame. The fabrics used in the triangle shaped iron frame diadem include plain weave silk, irregular plain woven silk, thin tabby, complex silk gauze, twill weave on plain ground, and warp-faced compound weave. The iron frames were wrapped with the fabrics from one layer up to three layers, and the iron diadem was covered with one later of loosely woven textile such as irregular plain woven silk, thin tabby, and complex silk gauze. But in case of decorating the iron diadem with gold Plate ornaments, multiple layers of fabric were used to sustain the weight of the ornaments. The fabrics in the iron diadem frame were sewed with running stitch, overedge stitch or hemming stitch, diagonal hemming stitch, half back stitch), and overcast stitch.

  • This article describes a method for producing chitosan non-woven fabrics by just hot pressing without the use of a binder. A study has been made of the wet spinning of chitosan fiber. The fibers were rinsed thoroughly in running water and chopped wet into staples of with a length of approximately 5-10 mm. The chopped chitosan staples were dispersed uniformly in water and fabricated using a non-woven making machine. This study examined the formation and the characteristics of chitosan non-woven fabrics manufactured by hot pressing without the use of a binder. The effects of the non-woven fabrication conditions on the thermal, morphological, structural, and physical properties of chitosan non-woven fabric with and without water as a plasticizer were studied. The temperature of the exothermic peak, decomposition of chitosan fibers increased with increasing heating rate. Water in the chitosan fiber effectively plasticized the chitosan fiber. The thermal bonded structure of the wet chitosan fiber with water as a plasticizer was clearly found in many parts of the non-woven fabric at a fabrication temperature of $200^{\circ}C$. The intensity and profile of the (100) plane($2{\theta}=10.2^{\circ}$) and (040) plane($2{\theta}=20.9^{\circ}$) in the chitosan non-woven fabric decreases and became smooth in the non-woven fabric formation by melting.

  • The Chonmachong (Tumulus No. 155 in Whangnam-dong, Kyungju, Korea), which was unearthed in 1973, is an ancient tomb built in the Shilla Era between the 5th∼6th centuries by the method of Juk-suk-mok-gwak. With the excavation of this tomb more than 11,500 articles of luxurious and splendid relics including gold and silver ornaments, weaponry and horse gears were obtained. Among the excavated articles, the saddle flap with a drawing of flying horse on it is the first relic of its kind from the Shilla Era. and 'Chonma'(a flying horse), the name of the tomb. was named after this drawing. The saddle flap is highly valuable in that it provides the idea of how goad the people of Shilla were at drawing. Although a lot of researches have been released about the relics from the Chonmachong, this study is to focus on the fabrics from the excavation, all of which are in the Kyongiu Museum's collection. The findings of this study are as follows : 1 The subject of this study is mainly on the fabrics used in horse gears, the pieces of cloth that were used to spread on a saddle or to underlay beneath a saddle. As the Shilla Dynasty tried to restrict excessive ornamentation on horses and it is assumed that the fabrics used are different. according to the social status. 2. The subject articles are four plain fabrics, three fabrics of combined -construction and one braid, the warp-faced compound woven silks of combined-construction was found for the first tinge in Korea, and is the typical quality sick with patterns woven with dyed threads in different colors. 3. It is ascertained by the Chonmachong excavation that polychrome woven silk was used not only for the clothes of the upper classes but also for the ornaments of their horses in the Era of the Three Kingdoms.
