The studies on shrinkage and characteristics of the weft knitted fabrics were investigated under the various dry and wet treating conditions. Various relaxation values were found out according to treating conditions. The characteristics of knitted fabrics such as shrinkage rate, thickness, spirality, elongation and recovery were also measured. The used knitting yams were OE (open-end) cotton and POY (pre-oriented yarn)-DTY (draw textured yam) polyester. The conclusions obtained in this study are as follows. 1. In case of dry relaxation little change of Ks values was seen with increasing time after 48 hours. So it was found that relaxation shrinkage of dry relaxation reached its maximal state in about 48 hours. 2. In case of wet relaxation, higher Ks values were observed, in comparision with those of dry one and higher shrinkage rates were also observed. But when experimental temperature was constant, sudden marked increases in Ks values and shrinkage rates appeared through the initial 4 hours, and after that time little change was seen in them. 3. As Ks value increases, thickness also increased. But thickness showed to some degree stability around Ks value 23. 4. As Ks value increases, spirality values also increased gradually. But little change of spirality values was observed above a certain Ks values (cotton 22.5, polyester 21.5). 5. As Ks value increases, the elongation decreased under a certain load, and the recovery was random.

A Woolen carpet from the late Joseon Dynasty was unearthed in the process of repairing Seongjeonggak in Changdeokgung. Since relics are rarer than documentary records, the woolen carpet is highly valued as a relics. It is presumed to have been woven in the late 19th or early 20th century because there is a record of repairing Seongjeonggak in 1907. In the carpet, a pattern is made by inserting colored yarn dyed yellow and red onto a reddish-purple ground weave. The selvage of the woolen carpet used cotton thread, and jute is used for the warp and weft of the ground weave. The colored patterns is made of wool in the form of loop pile. Cut piles may appear occasionally when the colored yarn changes, but are almost invisible from the surface because they are pressed tightly with a shuttered weft. Making carpets with jute and wool is thought to be influenced by the Brussels carpets of the mid-18th century. Furthermore, the woolen carpet is torn and the pattern is completely unclear; however, it is understandable that the pattern is partially repeated. Microscopic and Fourier transform-Infrared spectrometer(FT-IR) analyses were performed for the above investigation. To identify the dyes used in relics, we compared them with natural dyed fabric samples based on chromaticity measurements and Ultraviolet/Visible spectrophotometer(UV-Vis) analysis. These analyses revealed that the woolen carpet's dyed green yarn did not use indigo, and reddish-purple ground weave is estimated to have used Caesalpinia sappan.

The purpose of this study is to analyze the preference of design and body shape for korean baby-boom generation women. For this study, in-depth interviews were carried out to 11 women who were born in 1955~1963. They are called korean baby-boom generation. The results were as follows; 1) Korean baby-boom generation women care to their body shape, and they make much of the balance of body, not just looking slim. 2) Korean baby-boom generation women become more interested in their clothing, and they want to look with casual image than elegant image before. But overweight women preferred elegant image. 3) Korean baby-boom generation women prefer mix-match style for everyday clothes, but they prefer suit-set for formal wear. 4) When Korean baby-boom generation women choose of jacket or coat color, they consider more of their body-shape than season color. 5) Korean baby-boom generation women prefer plain style and jacquard with metal yarn. 6) Korean baby-boom generation women prefer out-door cloth fabric, at special time, they choose pure wool and pure silk. At ordinary time, they like more comfortable fabric like cotton mixed spandex or wool mixed spandex blends.

This study has been conducted to develop a new recycling technology of sewage sludge using a carbonization process. The carbonizing yield, the calorific value and EC(electric conductivity) of carbonized sewage sludge had a tendency to be decreased with increase of the carbonizing temperature and time, but pH and the C/N were increased with increase the carbonizing temperature and time. The whole pore volume of carbonized sludge processed in the carbonizing furnace was /g, which was smaller than that in the electric furnace. But, the rates of mesopore and macropore were found to account for 100% therein. Rate of color and organic materials removal for dyeing wastewater were determined 70~97%, 78~83% on cotton yarn, 88~96%, 69~80% on wool wastewater and 77~89%, 77~87% on towel compared with powder activated carbon. Effect of carbonized sludge on chrysanthemum growth was investigated. Plant height and number of leaves was better mixture of carbonized sludge than comparison.

This study developed a vest prototype capable of monitoring body temperature using textile electrodes to prevent the sudden death of babies as well as to determine the quality of developed products by evaluating usability with commercial products. Based on the results of the 7th Size Korea Project, a basic pattern for a vest prototype was drafted by applying the average size of two-year-old Korean babies. Two prototypes were the detachable (VEST I) and integrated textile electrodes vest type (VEST II), which followed the same design. The materials were 100% cotton single jersey (SJ) and double jersey (DJ). Six experts evaluated the usability of the developed vests (VEST I & VEST II) and commercial product (VEST M). The single-layer woven textile electrode appeared to have a slightly higher conductivity than the double-layer one. There was no statistical difference in the body temperature sensing function between VEST I and VEST II. Finally, the superiority of the VEST I was verified through a comparison with commercial products (VEST M). The usability test suggested that a wearable smart clothing system of the integrated conductive textile could be further commercialized for bio-monitor applications in Ubiquitous-health care.

In the variation of physical properties of adhesive fabrics, the objective of this study is to analyze fitness of fusible interlining to four sorts of fabrics for men's suit with various structural parameters. Four fusible interlinings are used for adhering to fabrics for men's suit. Mechanical properties of these 16 adhesive fabrics fused with these interlinings are measured by KES-FB system for analysing appearance and wearing properties of garments and for examining the fitness of fusible interlining to the fabrics for men's suit. The variation of bending property for adhesive fabrics are found to be higher in the order of interlining 1(Cotton30/Rayon70, plain), interlining 2(Polyester30/Rayon70, warp knit), interlining 4(Polyester, shingosen fabrics with drawing textured yarn) and interlining 3(Polyester, double dot coating interlining). The variation of adhesive effect shows the same results with bending property and shows negative relation with extensibility in weft direction per extensibility in warp direction(EM2/EM1). The variation of peel strength of adhesive fabrics, woolen fabrics in the case of face fabrics and interlining 3 in the case of interlining shows the largest value respectively.

Performances of Taekwondo fabrics were evaluated in respect of fiber component. yarn count, weave structure and wearing comfort. As a beginning step, we investigated the present situation of Taekwondo wears by questionnaire from pro and amateur Taekwondo players. Samples employed in this study were cotton/nylon blend fabric that was newly woven for this study as well as fabrics of current Taekwondo wears for sale in the market. Their fundamental properties measured were such as air permeability, water vapor transport. wickability, absorption rate, Qmax values, thermal conductivity, durability, hand value, and etc. In addition, subjective wearing sensations were evaluated using Taekwondo wears made of those fabrics. From the results of the objective measurement and the subjective wearing test, we estimated the total fitness of fabrics as a Taekwondo wear. From the questionnaire we could see that pro players and amateurs wanted highly absorbing, quick drying, and soft-tough and complained abrasive surfaces and static elasticity of current fabrics. In view of the results so far achieved, nylon blended fabrics newly woven in this study, showed better comfort-related properties from both of the objective and subjective tests. It was also represented that finer yams enhanced water absorption and touch, and fabrics with rough surface such as honeycomb weave was superior in wearing comfort as well as aesthetic appearance.

Kenaf was cultivated and harvested in large quantity in Cheju Island and Chinju, Kyungsangnamdo. It was chemically rotted with 3% NaOH for 60 minutes at 100$^{\circ}C$, neutralized using 1% acetic acid, washed and dried, and obtained 40kg of dry kenaf fiber. Kenaf 15/rayon 85, flax 15/rayon 85, and rayon 100% yam was spun and the physical characteristics were measured. Plain weave and twill weave fabrics were made using each of the above yarns as the filling yam. Cotton 100% yam was used as the warp yam in all fabrics. Kenaf/rayon blend yarns were higher in tenacity and elongation, lower in yam uniformity, higher in the number of nep than the flax/rayon blended yams. Kenaf/rayon blend fabric had higher tenacity and elongation compared to the flax/rayon blend fabric Kenaf/rayon blend fabric was most stiff in both plain weave and twill weave fabrics whereas drape characteristics was dependent upon the fabric structure of the kenaf/rayon blend and flax/rayon blend. There were little differences between the kenaf/rayon blend fabric and the flax/rayon blend fabric in the Kawabata physical measurements and the PHVs. The only drawback of kenaf fiber was it's surface roughness and it is expected that it can be improved by enzyme retting and mechanical bundle separation.

The purpose of this study was to investigate the fashion trends of last three years and how the trends were imaged by the structural characteristics of the fabrics. The characteristics for 897 fabrics were analyzed from four kinds. eleven volumes of fashion trend magazines. From these magazines, three panels categorized by their frequencies as nine images such as natural, innocent, ethnic, childish, casual, classic, modern and technical, Sub-images of each image such as rustic, irregular, decorative, etc were also categorized. For the each image, fiber contents and structural characteristics of weave type, weight, density, yarn size, twist and fabric finishes were investigated in terms of frequency, range and mean, Results showed that chiffon and organza seemed to have very specific images and used to represent specifically the romantic or ethnic images; whereas voile and jersey was used to represent various images. For S/S seasons, most popular fiber type was cotton. The weave type was not the important factor to give variations in images; plan weave exclusively used irrespective of image. For the romantic, ethnic and innocent images, rather light fabrics were used. For the childish and natural, medium weights, and for the technical, modern and classic images heavy weight fabrics were used. Vaious finishes were employed to represent specific images.
