In order to help develop more comfortable seat cover fabrics, this study primarily surveyed the actual using conditions and the consumers' opinions of the seat cover fabrics. The results of this study were as follows: 1) The colors of seat cover fabric were mostly achromatic. Regarding comsumers' satisfaction on the colors of seat cover fabric, comsumers in their 20's were less satisfied than other age groups. Most unsatisfied consumers prefered bright colors. 2) On the materials of seat cover fabric, synthethic leather and woven were most widely used. Real leather was most prefered due to its luxury and tactile sensation. Woven was secondarily prefered due to its price and tactile sensation. About fourty percent of consumers covered the seat with other cover fabrics because of soil and other reasons. It will be useful if they could choose and change the seat cover fabircs with different materials and colors. 3) When consumers used the seat cover fabrics, the problems that they indicated were not durability and colorfastness but low breathablity during sweating, static electricity, soil, firmness, and cool sensation at the first contact.

We studied the photocatalytic functionality such as deodorant, antibacterial, fine dust collection efficiency of polyester-based non-woven fabric filter treated with self-actuated photocatalyst. According to UV/visible result, the UV-visible peak of visible-light responsive photocatalyst was found to be red shift at 420 nm sensitive in the visible light region. The deodorizing performance was shown to be reduced more than 80% even without dark conditions. Fine dust particles collection efficiency was shown to be excellent at the size of not only $2.5{\mu}m{\sim}10.0{\mu}m$ but also less than $2.5{\mu}m$. Also antimicrobial and antifungus was shown to be reduced more than 99.9%.

In this study, the mechanical properties and hand characteristics of the knitted and woven fabrics for bedding items are investigated in accordance with fabric structural parameters including the fiber type and proportion, the density of the fabric, and the knit/weave structure. The knit stitches and structure of the knit samples made an effect on tensile properties. The bending, shear and compression properties for the knit fabric were mainly affected by fiber contents of the samples. The tensile and bending properties of woven samples were highly correlated with the fabric density, thickness and structure, and those shear and compression properties were affected by the fiber contents and structure. Consequently, the primary hand values of the selected samples we developed were estimated to have good smoothness, fullness and softness, and soft feeling, which is well correlated to the parameters of consumer preference such as softness, warmness, and bulkiness. Also, their total hand values were increased.

Danchung(丹靑) is the traditional Korean patterns that are decorated with various colorful patterned paintings upon each sections of wooden architecture. Although Danchung consists of variety patterns with the meaningful signs and symbols, as an accomplishment of Korean traditional images, there is a few fashion merchandise by Danchung patterns. Therefore, the purpose of this study is about to design Jacquard fabrics, and to develop bags of Jacquard fabric by Danchung patterns, as a differentiated cultural Fashion Merchandise. The theoretical background was researched for the geometric image of Danchung patterns on the basis of the basic elements, compositions and symbolic meanings of Danchung. The geometric image of Danchung patterns, which had the shape of circle, triangle, square and hexagon, was designed to the surface design by Jacquard CAD system(i.e., EAT Designscope by Germany) and woven into Jacquard fabrics by Stabuli electronic Jacquard system. Danchung patterns for fabric design in this study was mainly focused on 'ChipJaGum', 'SamJiChangGum', 'ShouSulGum', Moro patterns of lotus flower(蓮花), Rok-Wha(綠花) and so on. To development bags of jacquard fabric, those woven jacquard fabrics were manufactured to bags by applying the selected of twelve bag-designs among the current bag styles. These manufactured bags of jacquard fabrics in geometric Danchung patterns were appeared a contemporary yet ethnic feeling so that they can be used for the unique korean cultural products to further commercialization.

This study aims to evaluate the hydrolytic activity of a commercial nitrilase and optimize nitrilase treatment conditions to apply eco-friendly finishing on acrylic fabrics. To assess the possibility of hydrolyzing nitrile bonds in acrylic fabric using a commercial nitrilase, the amounts of hydrolysis products, ammonia and carboxylate ions, were measured. The treatment conditions were optimized via the amount of ammonia. The formation of carboxylate ions on the fabric surface was detected by X-ray photoelectron spectroscopy and wettability measurements. After nitrilase treatment, ammonia was detected in the treatment liquid; thus, nitrilase hydrolyzed the nitrile bonds in acrylic woven fabric. The largest amount of ammonia was released into the treatment liquid under the following conditions: pH 8.0, $40^{\circ}C$, and a treatment time of 5 h. The formation of carboxylate ions on the acrylic woven fabric surface by nitrilase hydrolysis was proven by the increased O1s content measuring of XPS analysis. From comparison of the results of nitrilase and alkaline hydrolysis, the white index and strength of the alkali-hydrolyzed acrylic fabric decreased, whereas those of the nitrilase-hydrolyzed samples were maintained. The nitrilase hydrolysis improved the sensitivity of acrylic fabrics to basic dye similarly to alkaline hydrolysis without the drawbacks of yellowing and decreased strength caused by alkaline hydrolysis.

An empirical review on silk fabrics of the Chosun period showed that they varied in kind and design according to their uses. Thus the purpose of this study is to classify the fabrics into excavated and temple fabrics according to their uses and collected places and then to examine characteristics of each type. Excavated fabrics were most accounted for by tabby fabric, followed by satin, twill, leno and gauze and union cloth. Tabby fabric was most used throughout the Chosun period, followed by satin. This is supported by many literary records. Concerning excavated dresses of the same period, tabby fabric, especially Ju was the main material, followed by satin. Leno and gauze fabric was much less used than in the Koryo period. Among excavated dresses surveyed in this study, none was made of compound woven fabrics such as Brocade. Other excavation reports said that Brocade had been used for a cuff of coat in few cases, if any. Tabby fabric was widely used for both the right side and lining while twill and satin fabrics were mainly adapted to weave the right side because they had luster higher than the former, smooth sense of touching and unique designs.

The average temperatures for year and winter season have been risen by $0.7{\circ}C$ and $1.4{\circ}C$, respectively, during the last 30 years. Recently abnormal climate phenomena occurred frequently results in severe loss of vegetable crops grown in Korea. Specially, Chinese cabbages grown in the southern area of Korea are often significantly affected by sudden cold waves during winter season before harvest. This experiment was conducted to find out a potential role of covering materials on the protection of frost damage of 'Bularm' chinese cabbage in the winter season. The lowest temperature was $-15.8^{\circ}C$ in non-covering, $-8.1^{\circ}C$ in the PE film covering and $-4.6^{\circ}C$ in the non-woven fabric covering with PE film, respectively. The cumulative times below $4.0^{\circ}C$ were 145.5 hours for the non-covering treatment, 94 hours in the PE film covering and 14.5 hours in the non-woven fabric covering with PE film, respectively. The symptoms of frost damage were severe at non-covering chinese cabbages compared to polyethylene film (PE) non-woven fabric with PE covering ones. Microscopic studies showed the normal anatomical structure of palisade and spongy tissue of cabbage leaves covered with non-woven fabric with PE film. Leaf cells, however, were slightly damaged in cabbages covered with PE film alone, and both palisade and spongy cells were were completely collapsed in uncovered cabbages. The result of this study suggests that chinese cabbages is required to be covered with non-woven fabric with PE film to minimize the frost damage by sudden cold wave below $-7^{\circ}C$.

This study aims to analyze the changes in the mechanical properties of woven fabrics(cotton, linen, wool, silk, and polyester) by bonding fusible interlinings with varying deniers(10D, 20D, and 30D) for a 3D virtual try-on system(one that a user to try garments through screens using Avatar) developed over the last decade. We experimented with four mechanical properties and thicknesses of twenty-three specimens of interlining bonded fabrics including face fabrics and interlinings by using the KES-FB-AUTO system. The results showed that the tensile property increased(LT and RT increased and WT decreased) as the denier of the interlining increased; however, the change was slight. In contrast, the bending and shear properties increased significantly as the denier of the interlining increased on both the warp and the weft. This showed evidence that the interlining gives the fabrics size stability. The compression property was slight changed as the tensile property varies depending on the fibers and the denier of interlining. As expected, the thickness increased by bonding the interlining as the denier of interlining increased. From these results, we conclude that 3D users need to reflect these changes of woven fabrics by bonding interlinings when they try screen fittings to accurately express the fabric reality of manufactured garment.

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.

Carbon woven fabric/C/SiC composites were fabricated by multiple impregnations of carbon woven fabric/carbon preform with the polymer precursor of SiC, i.e., polycarbosilane. In addition, two kinds of low density carbon/carbon preforms which had different fiber volume fraction and fiber orientation, i.e., a carbon woven fabric(${\thickapprox}$55 vol%)/carbon and a chopped carbon fiber${\thickapprox}$40 vol%)/carbon composites, were reaction-bonded with a silicon melt at 1$700^{\circ}C$ in a vacuum to fabricate dense carbon fiber/Si/SiC composites. The reaction-bonding process increased the density to ~2.1 g/$cm^3$ from 1.6 g/$cm^3$ and 1.15 g/$cm^3$ of a carbon woven and a chopped carbon preforms, respectively. All of the composites fractured with extensive fiber pull-out. The higher the density the higher the stiffness and proportional limit stress. The mechanical properties obtained from a three-point bend and tension tests were compared. The ratios of the peak tensile stresses to the bending strengths of a carbon woven and a chopped carbon composites were about one-third, respectively. The carbon woven fabric/Si/SiC composites with density of 2.06 g/$cm^3$ showed ~120 MPa of ultimate strength and ~80 MPa of proportional limit in bend testing.
