Developing of high technology, productivity of the fiber product has being rapidly increased and also various kinds of advanced treatment process lead consumer's needs to more high functional, clean and healthy goods. Moreover, increasing in the concern of eco-friendly material and processing, it has been getting popular that the dyeing method like as using natural dyes is more eco-friendly and natural-friendly treatment process. The method, used in this study, adhesion by binding with micro-capsulized natural material to fabric has low change in quality by external influence and high ability in spray effect by broken capsule which comes to pressure and friction when it dressed. Also it has wide application from natural fiber to synthetic fiber. The purpose of this study is development of multi-functional synthetic material with micro-capsulized Scutellaria baicalensis on PET. Moreover, it was driven by comparison of colormetric properties and fastness between regular dip-dyeing method and binding with micro-capsulized material method. Dye ability was arranged mostly low exhaustion but the PET treated by micro-capsule was more or less better than the dip-dyeing PET. Through the SEM(Scanning Electron Microscope) of PET treated by micro-capsule, it has good residence of capsules even after 5 or 10 times washing. Wash and light fastness was arranged some different grade by each condition but mostly high achievement and the micro-capsulized PET was more improved than regular dip-dyed PET.

Viscose rayon filament fabrics have been called 'artificial silk' and beloved as summer clothing materials for a long time in Korea. This is because the viscose rayon filament fabrics reveals glossy surface and cool touch feeling compared to other conventional fabrics composed of staple fibers. Therefore, we tried to prepare the higher value added viscose rayon filament fabrics for summer textile products. In this study, we applied gallnut extract to the viscose rayon filament fabric to develop summer fabrics with natural color and multi-functions such as antibacterial and antioxidant properties. This process also pursue eco-friendly and multi-functional fabric finishing from the natural material "gallnut". In addition, various pre-treatment with cationizer, chitosan, or chito-oligomer was applied to the finishing process to improve the finishing efficacy and durability. Consequently, it was found that the active component of gallnut extract was successfully incorporated to the viscose rayon filament fabric through a pad-dry-cure process. And, the treated viscose rayon filament fabrics showed excellent antibacterial and antioxidant properties. Therefore, it was expected that the rayon filament fabrics treated by gallnut extract could be used as effective summer fabrics preventing the growth of bacteria and skin ageing as well as providing cool touch feeling. However, the pre-treatments were not that meaningful on the functionalities but effective on coloring.

The objective of this study is to develop eco-friendly, functional towel material utilizing cotton-Modal-chitosan blended(C-M-CH) yarn and natural dyeing with mugwort colorants. Dyeing properties of towels with mugwort colorants were studied by investigating the effect of dyeing conditions including concentration of mugwort colorants, dyeing temperature, and dyeing time, and the effects of mordants on dye uptakes were investigated. The C-M-CH towel showed better dye uptake than 100% cotton towel with mugwort colorants. The shade of towels got darker and red-yellowish tint increased by mordanting. Comparing with 100% cotton towel, the colorfastness of dyed C-M-CH towel was satisfactory showing above 3 grade which is the lowest grade to washing fastness. The antibacterial activity against Staphylococcus aureus and deodorization performance of towels were excellent and improved by dyeing with mugwort colorants. From the results obtained, it is concluded that the cotton-Modal-chitosan blended towel dyed with mugwort colorants can be used practically for an eco-friendly and multi-functional towel materials with excellent absorbance and drying properties.

This research developed maternity wear designed with a focus on the essential functions necessary for working women and adaptable to their body changes during pregnancy. Through Martin's anthropometry for 201 pregnant women, the size specifications for maternity wear was determined and a dress form was proposed, in order to provide the manufacturer with reference data and a prototype to verify their products' fit and suitability. From a monthly analysis on the body measurements of pregnant women, significant monthly differences and after pregnancy were found in weight, chest girth, bust girth, under bust girth, waist girth, and hip girth. Dress form was designed based on the average body measurements of women in their 6th to 10th month of pregnancy. The standard dimensions in the 8th month were 90cm (chest), 94cm (bust), 86cm (under bust), 97cm(waist: most protruding part on the side), and 99cm (hip). Compared with Japan's MAT-9 (for nine months), chest girth was the same, while the Korean waist girth and hip girth were larger by 2cm and 3cm, respectively. The woven fabric blouse was evaluated as having the best appearance, while the knitted fabric one was judged as being more comfortable it terms of functionality. For the pants, the design details of the lowered waist and curved waist belt were more functional. The tailored jacket was the best design for working women in terms of both looks and functionality. To summarize, maternity wear for working women, unlike general maternity clothes, should be designed with consideration for the wearer's somatotype and activity. Elastic materials were appropriate for functionality and dealing with physical changes. With the increasing of working pregnant women, such trials are expected to continue in this research area in order to develop functional maternity wear with multi-purposes such as breast-feeding, wearability after delivery and shielding from microwave.

In this study, the difference in the mechanical properties of silver and cotton weft knitted fabrics was studied. Six silver fabrics for the summer ladies' knit outwear were knitted varying knit structure and fabric density. Two commercial cotton knitted fabrics were selected to compare the properties. subjective sensation of hand of the fabrics was also studied. Mechanical properties of the fabric samples were measured by KES-FB system. From these, primary hand values(HV) were evaluated by the conversion equation (KW-403-KTU) and the total hand value(THV) was carried out according to the KW-304 Summer. The result of the research show that silver weft knitted fabrics had lower LT, RT, G, 2HG and higher EM, W, LC, WC, RC than cotton weft knitted fabrics. The use of silver yam contributed to increase in surface roughness of knitted fabrics. As the silver knitted fabrics became thicker compressional energy increased. The use of silver yarns contributed to much better fabric handle compared with the use of cotton yam only. It appeared that coefficient of friction of tuck stitch was larger than that of plain and interlock stitch. KOSHI and FUKURAMI values of the tuck samples were significantly higher than those values of the plain and interlock samples, while SHARI values were low in general. The total hand value of tuck stitch was higher than those of interlock and plain stitch.
