The wearing comfort of garment is governed by two kinds of characteristics such as moisture and thermal transport properties and mechanical properties of fabrics. The porosity influenced by yarn and fabric structural parameters is known as main factor for wearing comfort of garment related to the moisture and thermal transport properties. This study investigated effect of porosity of composite yarns to the moisture and thermal comfort properties of composite fabrics made of hollow composite DTY and ATY yarns. The theoretical porosity and pore size were inversely proportional to cover factor of fabric, but cover factor was not correlated with experimental pore size. The wicking property of hydrophobic PET filament fabric showed inferior result irrespective of porosity, pore size and cover factor. The drying rate was superior at composite fabrics with high pore size and low cover factor, and pore size was dominant factor for drying property. On the other hand, thermal conductivity of composite fabric was mainly influenced by cover factor and not influenced by porosity. Air permeability was influenced by both porosity and cover factor and was highly increased with increasing porosity and decreasing fabric cover factor.

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.

In this paper, static compressive test and compression-compression fatigue test of carbon/epoxy composites which have different micro-structures were carried out with respect to the bias angle. In order to find out the effect of the micro-structure of the fabric composite on compressive characteristics the specimens made of UD carbon/epoxy composite comprising the same fiber and matrix system as the fabric composite were also prepared. The compressive strength and modulus were measured and these values were used to develop a semi-empirical formula for predicting compressive strength of the fabric composite with bias angles. The fatigue behavior of the fabric composite with respect to the bias angle variation was also investigated.

Aging characteristics of glass fabric/phenolic composites for tilting train subjected to combined environmental aging factors were investigated. A 2.5KW accelerated aging tester with a xenon-arc lamp was used to provide environmental aging factors such as temperature, moisture, and ultraviolet. A series of aging tests were conducted up to 3000 hours and several types of specimens were prepared along the warp direction and the fill direction. Mechanical degradations for tensile, flexural, and shear properties were evaluated as a function of exposure times through a material testing system. Thermal analysis properties such as storage shear modulus, loss shear modulus, and tan 3 were measured through a dynamic mechanical analyzer. Finally exposed surfaces of the composites were examined using a scanning electron microscope. According to the experimental results, mechanical properties and thermal analysis properties of glass fabric/phenolic composites were found to be slightly degraded as a function of exposure times due to combined environmental effects.

Hand characteristics related with structural properties of fabrics have something to do with mechanical properties of fabric. In this study, the mechanical properties and hand characteristics have been analyzed according to fabric structural parameters such as the weave structure and the linear density of weft of cotton fabric. Mechanical properties have been used by KES-FB system which measures hand characteristics and mechanical properties of fabric. Linear density of weft, tensile, bending, and shear properties are decreasing with increasing weft linear density, and there is no considerable effects on compression and surface properties. In case of formability with weft linear density, B/W, 2HG/G, 2HB/B, 2HB/W, $\sqrt[3]{B/W}$, $\sqrt{2HB/W}$, W/T except MMD/SMD, WC/T, and WC/W have been effected. There is a high correlation between the crimp, tightness, hand, formability and mechanical properties specially tensile linearity, bending, shear, and compression properties. The weft crimp influences the bending rigidity, shear properties, and the tightness which have effects on the tensile linearity, bending, shear, compression properties, hand, and formability.

This study investigated Korean image preferences in casual wear of women consumers and the effects of demographic characteristics on Korean image preferences in casual wear. The subjects of the study were 653 women consumers who lived in Seoul. Data were collected during July, 2007. Statistical analyses used in the study were frequency, ANOVA and Duncan test. The results showed that respondents preferred to express Korean image by color in their casual wear. When it comes to specific preferences for pattern, fabric, and color, circular shape was most preferred as pattern, cotton was most preferred as fabric, and white color was most preferred as color. In addition, there were demographic differences in regard to preferences for pattern, fabric, color, and types of casual wear. The results showed that there were differences in age, occupation, income, and residence. For example, in regard to age, there were differences in the preferences for fabric, color, and types of casual wear. The older respondents preferred natural fabrics more while the younger respondents seemed to accept synthetic fabrics in their casual wear. Also, women aged over 40 preferred cotton pants for their casual wear. This study showed that demographic characteristics are important variables in segmenting the preferences of Korean image for casual wear market.

The surface fibers on the fabric is one of decisive factors which affects human sensory evaluation as well as heat and moisture transfer characteristics. In this study the length and distribution of surface fibers that are extruded from the fabric surface of the wool/wool blend fabrics (14 wool fabrics and 10 wool blend fabrics) and its contribution to subjective sensory evaluation were investigated. In order to quantify the length and distribution of surface fibers, image analysis and wavelet transform technique were introduced. Instant warm-cool feeling of touch, Q$\_$max/, and contact area were also measured and related to the quantified surface fibers. To figure out the effect of surface characteristics on sensory evaluation, human sensory responses to three adjectives which represent surface characteristics and warm-cool feeling of touch were obtained and analyzed. The relationship between the quantified surface fibers assessed by wavelet energy and both warm-cool reeling of touch, Qmax, and human sensory response were discussed.

In this study, we attempted to expect the mechanical characteristics of the wool fabrics by knowing the yarns. Moreover, we believe that we could apply these results to fabric design. We investigated the relationship between the mechanical characteristics of yarns and fabrics. As results, we have found that bending rigidity, bending hysteresis, compressional energy and compressional linearity between yarns and fabrics had correlated more than r=0.5. Also, the correlation between regression and experimental values is r=0.5 in stiffness while it is r=0.67 in fullness. And regression values were larger than experimental ones in stiffness, but were not in fullness. The correlation between regressional and experimental values had 0.63 in THV. According to the study, it is possible to apply it to fabric design when our predicting the primary hand and the total hand values of the fabrics from the mechanical characteristics of the yarns.

The purpose of this study is to examine the pieces of 100 fabrics excavated from unknown woman's tomb Incheon, by analyzing woven methods, names of the fabrics, the kinds and the shapes of the patterns. The characteristics to assume the period of the fabrics are as follows. The geumsundan which was woven peacock insignia at chest and back area was excavated for the first time from the tomb of Joseon. Peacock insignia woven with satin weave using supplementary golden wefts, wrapped gold thread. These kind of fabrics were usually imported in the $15^{th}$ century, according to the old documents, 'Nogeoldae' 'Joseonwangjosilrok' written at the end of Goryeo or early in Joseon. Thus, these relics are from about $15^{th}$ century. From this tomb, the mixture fabric of cotton and ramie are excavated. According to another excavated cases, the mixture fabric of cotton and ramie appears from the period before the Japanese Invasion of Korea in 1592, and after the invasion, there are usually mixture fabric of cotton and silk. This also tells that these fabrics show the characteristics of those from the early period of Joseon Dynasty. The rounded patterns of Jangot is only shown from the fabrics of late Goryeo Dynasty, and the cloud pattern of an upper garment with a squared neckline is shown from the early Joseon Dynasty. So, the patterns from these excavated costumes are ranged from the late Goryeo Dynasty to the early Joseon Dynasty. To assume the period through the overall study above, these relics show the characteristics of the $15^{th}$ century fabric.
