Heat storage/release system in textile is a useful tool to increase energy efficiency and enhance comfortable microclimate of clothing. Phase change materials(PCM) are used in regulating storage and release properties of thermal energy. To investigate the temperature regulating ability of fabrics with PCM microcapsule(PCMMc), Nylon fabrics were coated with PCMMc via wet processing and they were characterized by SEM, DSC and infrared thermal analyzer. Also, water moisture transpiration, water penetration resistance, peel strength and washing durability of the fabrics were assessed. The water vapor permeation and water penetration resistance decreased with increasing PCMMc content. In DSC analysis, it can be seen that the microencapsulated fabric showed both exothermic md endothermic phenomena at specific temperature. Peel strength was decreased with increasing PCMMc content.

This study was initiated to develop a uniform design suitable for child inpatients. The experimental hospital inpatient uniform design was developed based on the results of the prior studies. The panel was composed of 5 experienced nurses and 5 clothing specialists. They evaluated the function of the experimental inpatient uniforms developed in this study. The experimental hospital gown design was reformed based on the panel's evaluation.1'hen the child inpatients performed the wear test for the reformed experimental hospital gown. The results of the study are as follows; 1. The child inpatient hospital gown design of the most hospitals were similar to the adult patient's uniform : the V-neckline shirts with full length set-in sleeves. The bottom was full length pull-on pants. The fabric was white cotton with blue hospital logo and stripe print in most cases. 2. The panel's specialty affected the evaluation of the uniform design. The nurses concerned about the durability after washing and ease for medical treatment. The clothing specialists cared about the features related to the clothing construction and ease for physical movement of body. 3. The most preferred hospital inpatient uniform design by the panels was the shirts or one- piece gown with three-quarter length sleeve and overarm seam opening. 4. The researchers developed one-piece dress gown for the children under two years old. Three different size pajamas were developed for children 2∼5 years old,5∼8 years and 8∼12 years old.

This study was performed to investigate the effect of Artemisiae argyi Herba extract on the treatment of chromaticity and colorfastness. Artemisiae argyi Herba has been used as a Korean medicine. It is effective in removing skin disorders and suppressing pain. It is also good as a fungicide and in treating pruritis. In the long history of Korea, dyeing has been applied for a means representing the grace of natural and inner esthetic consciousness of man. Vegetable dyes give us such great benefits, diversified color; but no pollution. And ramie fabric has distinctive features such as beautiful brilliance, elegance, and strong durability. So, it is regarded as a special product of Korea traditionally. These studies were carried out to treat with acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was died with Artemisiae argyi Herba extract. The results of experiment showed as follows: First, the chromophoric degree was the highest in acetate iron but not distinction in another mordants. Seocond, the light colorfastness was the highest in non treated and dichloride copper, but alum was the lowest. Third, the discoloration was alum and dichloride copper showed first grade in washing colorfastness. Abrasion colorfastness was not significant in this test. According the previous results, Artemisiae argyi Herba has an efficiency in removing skin disorders and suppressing pain. So it is considered that Artemisiae argyi Herba can be applied effectively to theraphy of fungicide and in treating pruritis.

This study surveyed on the synthesis of one-step type hydrophilic non-porous PU resin and the physical property of the coated fabric for the garment. Three kinds of chain extender such as MEG, 1,4-BD and NPG were used for the preparation of one-step type hydrophilic non-porous PU resin in order to examine the effect of chain extender on the physical properties of PU-coated fabric. And the effects of isocyanate on the physical properties of PU coated fabric were surveyed by mixing with various TDI and MDI ratios. In addition, the physical properties of the coated fabric treated with one-step type hydrophilic non-porous PU resin were examined according to the pre-treatment conditions such as cire finishing. Finally, the washing durability of the coated fabrics was assessed. The coated fabrics treated with PU resin synthesized with PEG1000, MEG and TDI/MDI (6/4) showed the best physical properties. Considering the pre-treatment conditions, best performance of hydraulic pressure, water vapor permeability, and water repellency were obtained with top roller rotation ratio of 150% under 50 ton pressure at $170^{\circ}C$.

A pre-treatment process has been developed for natural dyeing of wool by which the dyed materials have been imparted antimicrobial efficacy against both gram-positive and gram-negative bacteria durable up to 20 washes. In this process, wool fabrics were treated with citric acid under oxidizing condition prior to dyeing. The treated fabrics were then dyed with four different types of natural dye powders obtained from leaves of silver oak, wattle, tanner's senna and flame of forest. All the natural dyes produced yellowish brown colour on wool fabrics. The washing and light fastness properties of the fabrics subjected to pre-treatment were one grade higher compared to those of the dyed fabrics without pre-treatment. The pre-treated wool fabrics showed antimicrobial efficacy against both gram-positive bacteria (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli). The fabrics dyed without pre-treatment showed antimicrobial efficacy against gram-positive bacteria (Staphylococcus aureus) only. The durability of antimicrobial efficacy was higher in pre-treated and dyed wool fabrics compared to the dyed fabrics without pre-treatment.

In order to investigate the effect of gallotannin treatment to ceramide-containing fabrics on atopic skin diseases, the agglomeration of standard protein BSA and the deactivation of model enzyme were examined. The gallotannin treated on ceramide-containing fabrics precipitated the standard protein, BSA, and therefore deactivated the model enzyme by 70% at 6% treatment concentration. Wash durability should be improved after around 5 cycles of washing. Clinical test of the gallotannin-treated fabrics was carried out on mice for two test items, transepidermal water loss assay and severity score of diseased skin of mice. The results showed significant level of improvement of atopic skin diseases compared with the negative controled.

Nano Inkjet DTP technology, a new technology introduced recently, can be applied to various types of fabric, and pre-treatment process can be omitted, which makes the whole printing process compact. Some important factors for DTP are color difference between the color selected by the designer on PC and the color on the final product and durability of the final fabrics. In this study, the twenty-three trend colors of 2012-2013 F/W suggested by PeclersParis have been picked to be printed on cotton, silk and polyester fabrics, then K/S and ${\Delta}E$ value and color fastness were measured. The results show that dyeability of fabric is varied for each color group, and that also tone of color affect to dyeability when measured for colors in the same group. In general, for all fabric, light fastness, washing fastness and color fastness to sublimation are outstanding. However, because of poor rubbing fastness, additional treatment to fix colorant on fabric is required.
