  • In one dyeing system of silk/synthetic blend fabrics (polyester, nylon, acetate) with acid dyes/disperse dyes, dyeability and desorptibility of disperse dyes on silk fabric and transfer from dyed silk fabrics to synthetic fabrics by color difference were examined. When silk dyed with C.I. Disperse Red 19 and C.I. Disperse Red 60 at 10$0^{\circ}C$ for 60 minutes, color difference of dyed silk were $\Delta$E=56.72, $\Delta$E=47.65 for blank silk, respectively. The desorption rate of the dyed silks were measured in boiling bath with and without dye-free synthetic fibers. The desorption rate of dyed silk was effected by affinity of synthetic fabrics contained. When silk dyed with Red 19 and Red 60 was reduced at 10$0^{\circ}C$ for 60 minutes, the decolouration rates of dyed silk were 75% and 40%, respecdtively.

  • Cotton and silk fabrics were dyed with Houttuynia cordata extract using aqueous ethanol solution and the dyeing and post-treatment conditions were optimized to impart antimicrobial activity to the fabrics. The dried Houttuynia cordata can be extracted at $80^{\circ}C$ for 3 hours using an aqueous ethanol solution containing 70%(w/w) ethanol. For the highest color yields. Both cotton and silk fabrics can be dyed at $100^{\circ}C$ for 60min with 10g/L of NaCl under pH 4. Silk fabrics can be dyed to higher K/S than cotton fabrics. The color fastness properties of the dyed fabrics were good when either citric acid crosslinking or aluminum alum mordanting was carried out as a post treatment. The dyed silk and cotton fabrics with the post treatments showed excellent antimicrobial activity against both Staphylococcus aureus and Klebsiella pneumoniae.

  • Silk organza can make the silhouette of clothes bulky and rich, owing to its stiffness. And silk organza in the gum has better dyeability so can be dyed more bright and deeper color than scoured silk because silk organza has sericin gum that has better dyeability than fibroin. So, silk organza came into the most broad use as the material for Hanbok, especially in summer. But the silk organza has poor color fastness. Sericin is removed from organza when silk organza go through scouring. The purpose of this research is to find out the optimum conditions that the scoured silk fabrics can get stiffness by persimmon juice treatment. For experiments, non scoured, partially scoured and fully scoured silk fabrics were prepared by alkali treatments. Then 3 kinds of silk fabrics were treated with the concentration of 1, 5, 10, 50 and 100% of persimmon Juice. The change of fiber surface of the various silk fabrics were observed By SEM. The hand values of those fabric samples also were measured hand values by Kawabata Evaluation System and stiffness by Cantilaver method. By scouring, the silk organza got more flexibility and less cohesiveness between their fibers. And it can be a little more bulky by removing gum. Namely, silk organza lost its unique stiff and crisp handle. By the persimmon juice treatment, tannin component could be coated on the fiber surface. so that the stiffness of the fabrics were improved.

  • To develop natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the dyebath extracted from wisteria. Dyeing experiments were done under different dyeing conditions of dyeing temperature, pH of dyebath, dyeing time, concentration of dyebath and mordant treatment which were treated after dyeing. Experimental fabrics were silk, wool, cotton, ramie and hemp. Color difference(ΔE) and Munsell's HV/C of the dyed fabrics and color fastness of silk and cotton fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. In silk and wool fabrics(non mordant, dyeing time-20min), color differences increased in case of dyeing temperature of $100^{\circ}C$, but in cotton, ramie and hemp fabrics, color differences did not increase. Without mordant treatment, color differences of all experimental fabrics were about 10-20, so in wisteria dyeing mordant treatment was necessary. Color differences were increased by the mordant treatment; the color of dyed fabrics with Al mordant is dull yellow, Cu mordant is gold and Fe mordant is olive tone. Color difference was not affected by pH of dyebath in all experimental fabrics. On the whole, the color fastness of dyed silk and cotton fabrics were good, but color fastness to washing and perspiration in Fe mordant was weak and improved in Cu mordant.

  • In order to investigate the hand values and mechanical properties such as tensile, shearing, bending, compression, surface and thickness & weight of the women's summer fabrics were measured by KES-F system. Sorts of 78 commercial fabrics of women's summer cloth were classfied into 43 silk and 35 polyester fabrics according to materials. The experimental results were analysed statistically to relate the hand values and the mechanical properties and concerning to formation of weared clothes and transformation behavior were investigated. The main results are summarized as follows; 1. Polyester fabrics show higher tensile deformation than those of silk fabric. And also polyster fabric has a easy to shape-less and makes a silhouette which goes along with the body. 2. Silk fabrics is superior to polyester fabrics in formation and shear elasticity building box-shaped silhouette. 3. Polyester fabrics show sufficient ability to recover from tending deformation and drapability On the other hand, the compressibility and bending rigidity of silk fabrics were superior to polyester fabrics. 4. Regardless of materials, the bending properties is closely assocsiated with stiffness, anti-drape stiffness and flexibility with soft feeling. Fullness & softness and crispness is primarily influenced by surface properties. There is substantive relationship between scrooping and sheaing properties.

  • Recent trends toward the collaborations among various sectors of academia and research areas have brought interests and significances in new activities especially in the fashion and textile areas. One of the collaboration examples is the recent research projects on 3D virtual clothing systems based on the 3D CAD software. The 3D virtual clothing systems provide simulated apparels with high degrees of fidelity in terms of color, texture, and structural details. However, since real fabrics exhibit strong nonlinearity, anisotropy, viscoelasticity, and hysteresis, the 3D virtual clothing systems need fine tuning parameters for the simulation process. In this study, characteristics of silk fabrics, which are woven by using degummed silk and raw silk yarns, are being analyzed and compared. Anisotropic properties may be measured as warp and filling direction properties separately in woven fabrics, such as warp tensile stress or filling bending rigidity. Hysteretic properties may be measured as bending hysteresis or shear hysteresis by using KES measurements. These data provide deformation-force relationships of the fabric specimen. Three-dimensional effects obtained when using these characteristic fabrics are also analyzed. The methods to control the three-dimensional appearance of the sewn fabric specimens when utilizing a programmable microprocessor-based motor device, as prepared in this study, are presented. Based on the physical and mechanical properties measured when using the KES equipment, the property parameters are being into a 3-dimensional virtual digital clothing system, in order to generate a virtual clothing product based on the measured silk fabric properties.

  • The purpose of this study was to improve dye effect and method in order to facilitate the use of persimmon juice dyeing. Silk fabrics were pad-dyed to 100% pick-up using padding machine after dipping in persimmon juice extracted from unripe persimmons indigenous to Jeju. The color of dyed silk fabrics by padding method was more even and repeatable than that by traditional hand method. Persimmon juice concentrations were 4 types 10, 25, 50 and 100%. The silk fabrics were pad-dyed to 100% pick-up and were repeatedly dyed two times and three times with 100% concentration. The higher the concentration, the more color deepened. UV Irradiation instead of sunlight was applied to color developing. Irradiation times were shortened to 1-8hrs. Color values which reguired 30-50 hrs. in sunlight irradiation. were obtained in 3-5 hrs. with UV irradiation. Tensile strengths of silk fabrics in UV irradiation decreased but not decreased in sunlight irradiation. Elongations of silk fabrics in sunlight irradiation increased but decreased in W irradiation. Drape stiffness increased up to three times.

  • In this study, cross-cultural comparison of sound sensation for Korean traditional silk fabrics between Korea and America was performed and prediction models for sound sensation by objective measurements including sound parameters such as level pressure of total sound (LPT), Zwicker's psychoacoustic characteristics, and mechanical properties by Kawabata Evaluation System were established for each nation to explore the objective parameters explaining sound sensation of the Korean traditional silk. As results, Koreans felt the silk fabric sounds soft and smooth while Americans were revealed as perceiving them hard and rough. Both Koreans and Americans were pleasant with sounds of Gongdan and Newttong and especially Newttong was preferred more by Americans in terms of sound sensation. In prediction models, some of subjective sensation were found as being related mainly with mechanical properties of traditional silk fabrics such as surface and compressional characteristics.
