Modern society is age of sports just as health and leisure became dominant concern, which has caused the fixation and development to sports wear considered as fashion for everyday dress. This paper focused on the development process and aesthetic characteristics of knit design expressed in the 20th century sports wear. The importance and direction of knit design in modern sports wear is expected. Style, items, fabrics, colors, details and top designers were analyzed in sports wear from the 1910' s to 1990' s. Sports wear can be categorized into two of the active sports wear and spectator sports wear. Since disappearance of division between ordinary wear and sports fashion in the 1970' s, the functional wear of leggings, cycle shorts, exercise clothes, leotard, and leg warmer appeared. Vicennial developments of synthetic fibers and new fabrics have caused the great changes in knit design. Colors were vivid in the 1950' s, metallic in the 1970' s and neon in the 1990' s. Sportive sense was expressed by various details. The dominant knit designers who expressed aesthetic characteristics to sports wear were Coco Chanel, Claire McCardell, Balenciaga, Andre Courrege, Pierre Cardin, Yves Saint-Laurent, Ralph Lauren, Donna Karan, and Giogio Armani.

The aim of the study was to look into the construction methods of historical corsetry and compare them with the construction methods of corsetry today. Through a comparative study, it was concluded that the design, material, sewing and functions of corsetry of a certain period are sum of the clothing techniques and fashion of the time. Corset was first appeared at the end of the 16th century. It has been through many changes in terms of items, materials, patterns, sewing methods in order to make right silhouettes of the time. Now corsetry has been developed into various items such as waist nipper, all-in-one, nipper bra, and girdle. All these items have a common purpose, that is to improve the body shape. The corsetry of the past was made of non stretchable materials, so they used to restrict body movements, and required individual fitting several times. Due to the development of thin durable stretchable fabrics, functional bones, and advanced sewing machines, construction methods of seam, hem and opening are simplified compare to their predecessors. Consequently corsetry became less weighted, easy to wear, easy to wash and easy to mass produce. Yet they have consistency in sewing techniques such as using bones or wires to support bodice shape, using durable twill fabrics over plain for attractive body shapes.

This study selects representative materials and sewing methods used to: produce medical compression clothing in domestic garment, understand physical properties according to sewing conditions before and after knitting, and propose a sewing method that can improve the functional properties of the medical pressure clothing for burn patients. This experiment used samples from two knitted fabrics of high-frequency, produced and sold among fabrics used to produce medical compression clothing in Korea. Sewing methods were N321, N502 and N601, most commonly used in the press clothing industry. Fabric A is most often reduced in EMT values when sewing N502. However, N321 and N502 are suitable sewing methods for the reliable to twist at the larger torsional shear and the larger 2HG, 2HG5 value. Fabric B is sewn with N601, the EMT value is the most elevated, LT value is also low and extensibility improves after sewing. N601 is shown as an appropriate sewing method for warp knitting. When sewing with N321, the torsional is stable but elongation is lacking. N502 is not good for torsional stability.

This study is fundamental research on how to be able to scientifically quantify and reproduce a natural dyeing procedure. By dyeing silk fabrics, the establishment of a reproducible dyeing method was sought. Juglans mandshurica has been known as one of the most widely used black vegetable dyes. Repetition conditions and combination dyeing were performed with Juglans mandshurica cortex, gallnut, clove, and Eclipta prostrata L. extracts to express a deep black color. Juglans mandshurica cortex, gallnut, clove, and Eclipta prostrata L. extracts were suitable for black coloration and showed a darker black color when combined with iron mordant. Specifically, Juglans mandshurica cortex and clove can be used for deep black coloring. Color fastness when washed or dry cleaned was found to be strong with a grade of 4-5 and fastness to light was rated at a 3-4. The grade of color change when exposed to rubbing and perspiration was good at a 4-5. In regards to functional property aspects, it showed excellent results with a 99% deodorization rate at 120 minutes of dyeing time, 97.1% UV protection rate, and 85.9% and 62.3% bacterial reduction against Staphylococcus aureus and Streptococcus pneumoniae, respectively. Therefore, it is considered that the extract from the Juglans mandshurica cortex is of great value as an eco-friendly, natural dyestuff.

As the old saying 'nothing is complete unless you put it in final shape', although nanosheets (NSs) are a promising functional building block for various electrochemical applications, their true value cannot be realized until they are well woven into electrical conducting materials. As an effort to determine their ideal shape, in this study, a unique manufacturing route to build a layer-by-layer (LBL) structure of two-dimensionally ordered, free-standing ${\beta}$-nickel hydroxide nanosheets (${\beta}$-NHNSs) that are fully electrically addressed with single-wall carbon nanotube fabrics was demonstrated, and its capabilities were verified through a comparative study on the differences between a simple bulky and LBL-structured electrochemical cathode, representing two extreme cases. The LBL-structured cathode showed a discharging current peak that was 25 times larger than the bulky structured one measured in cyclic voltammetry, which implies that the LBL structure is near an ideal electrode configuration for NS-based electrochemical applications.

We have treated polyester fabric with $CF_4,\;C_2F_6,\;SF_6\;and\;C_3F_6$ glow discharge plasmas to develop functional fabrics which preserve moisture transportation and water proofing nature. Modified properties were evaluated by water vapor permeation rate and breakthrough water pressure. The change of surface morphology was observed by SEM. Fiber interstice of the plasma treated fabric was calculated as $0.32{\mu}{\textrm}{m}$, and this value was sufficiently ideal as water repellent material. The moisture transportation of ${CF_4}-treated$ fabric was good as much as untreated fabric, and those of $C_2$F(sub)6-treated, SF(sub)6-treated fabrics were reduced by 1~3%, and that of ${C_3F_6}-treated$ fabric was reduced by 15%. The best treatment condition were 0.06 torr 120 seconds in $CF_4$, 0.05 torr 30 seconds in $SF_6$, 0.08~0.15 torr 90 seconds in $SF_6$ and 0.1 torr 45 seconds in $C_3F_6$ respectively. The grade of moisture transportation effect was $CF_4>C_2F_6>SF_6>>C_3F_6$, and water proofing effect was $C_2F_6{\approx}CF_4>C_3F_6>SF_6$. It was observed by SEM that the thin film was formed on the surface of the treated substrate by the fluorocarbon plasma treatment.

Poly(ethylene-co-vinylacetate)(EVA) microspheres were prepared by a thermally induced phase separation. The microsphere formation occurred by the nucleation and growth mechanism in the metastable region. The diluents used were toluene. The microsphere formation and growth was followed by the cloud point of the optical microscope measurement. The microsphere size, which was obtained by SEM observation and particle size analyzer, became decreased when the titanium dioxide($TiO_2$) concentration was higher. The deodorizing function of the prepared fabrics was studied by the determination of the decomposing capability for $NH_3$. The deodorant activity of these deodorizing fabrics was measured by chromogenic gas detector tubes. The deodorant activity of $NH_3$ increased with increasing $TiO_2$ concentration of EVA microsphere.

The aim of this study is to investigate the actual state for the development of the thermally comfortable uniform for workers on a low temperature storage. Observation, interview and survey were executed focusing on the environment, clothing, and human factors which have effects on the comfort of workers. Of 400 distributed, 253 questionnaires were analyzed through descriptives, frequency, ANOVA, t-test, multi-response analysis, correlation analysis with SPSS 12.0. The results are following. Coming and going between a selling area and cold storages, the workers showed to experience a big temperature gap. They indicated to feel cold on face and hands which were not covered by clothing and have got sick because of low temperature. The workers wanted the uniform made of functional fabrics, especially heat insulation fabrics. Female workers rather than male workers, the older, and the longer their working period were, the more uncomfortable they revealed to feel. The workers who works on the daily products part or mainly on the freezer appeared to feel cold more than any other workers. In conclusion, it was found that the uniform which consider steady state and unsteady state heat transfer together must be developed.

Phase change material(PCM) has thermal energy storage and been attracted attention. Latent heat of the organic PCM can keep maintaining temperature when the change of outside energy conditions influence to PCM. Thus, many researchers have interested to thermal energy storage ability and investigated to applications such as thermal storage of solar energy, bioclimatic building, icebank, medical application, clothing industry and so on. Among the many applications, investigation of the PCM in clothing industry is also important because the people has interest functional factor called health-care in the clothing. In addition, PCM can give them mild environment condition such suitable temperature control or humidity. To fabrics, the PCM has various methods such as microcapsule, padding and modified cross-section formation(Sheath/core). Sheath core PCM fabric has a better benefit of durability than other method. However, PCM sheath/core spinning is difficult. In addition, dyeing property is important to use clothing industry due to visual images. In this study, we investigated dyeing properties of Nylon/PCM sheath/core fabrics. Especially, we observed the relation between dyeing property and PCM including ratio. Various temperature and pH conditions were also studied to optimize dyeing properties as acid dye.

In this study, the dyeing properties and functionalities of Crataegi fructus extract were investigated for the purpose of application to new natural dye resources. The effects of dyeing conditions(concentration of dye, dye bath temperature, dyeing duration and dye bath pH) and mordanting on dye uptake and color changes were also examined. The study also estimated the colorfastness, antibacterial properties, and ultraviolet protection properties of the dyed and mordanted silk fabrics. The dye uptake increased in tandem with the dye concentration and dye bath temperature. The highest K/S values were obtained at the following conditions: a dye concentration of 100%(v/v), a dyeing period of 60 minutes, a dye bath temperature of $90^{\circ}C$, and a dyeing pH of 3. The colorfastness of the material when dry cleaned or rubbed ranged from good to excellent and fastness to light was rated at grade 2-3. The change in the color grade when exposed to washing was not good; however, the stain of washing fastness was good at a range of 4-5. In regards to the functional property aspects, the dyed and mordanted fabrics exhibited excellent results with a 99.9% reduction rate, and excellent ultraviolet protection factors.
