  • This study was to investigate the application of foam finishing technology (FFT) for the silicone finishing of cotton fabrics and the tluorochemical finishing of polyester fabrics. The repellency properties, soil resistance properties and selected physical properties were demonstrated and compared the foam finishing with the conventional padding application. Amino-funetional silicone prorided better durability than epoxy-functional silicone and conventional reactive silicone after three launderings. Foam finishing fabrics improved stiffness but showed lower or equivalent water and oil repellency properties, soil resistance properties, tearing strength and abrasion resistance than those of the fabrics treated by conventional padding process. But, it was evident that the foam application of silicone and fluorochemical finishes to the fabrics were feasible.

  • The purpose of this study is to investigate the proper dyeing condition, color fastness and functionality of silk fabrics dyed with Zizania latifolia Turcz. FT-IR spectrum analysis suggests that colorants of Zizania latifolia Turcz. are tannins. The dyeing of the silk fabrics using Zizania latifolia Turcz. was very good even without pretreatment or mordanting treatment. Optimal dyeing conditions of silk fabrics were colorant concentration of 200%(o.w.f.), dyeing temperature of $100^{\circ}C$, dyeing time of 60 minutes and dyebath pH of 5.5. Color fastness of dyed silk fabrics to washing, rubbing, perspiration and light was 4~4-5, 5, 4~4-5(acidic), 4-5(alkaline) and 2 respectively. UV protection rate and deodorization rate of silk fabrics dyed with Zizania latifolia Turcz. were improved. Reduction rate(Staphyloccus aureus) of silk fabrics was excellent at 98.3%. As a result, it was confirmed that the Zizania latifolia Turcz. could be used as an eco-friendly functional natural dye.

  • The intent of this study was to focus attention on the relationship between curtain fabrics and consumer perceptions towards curtains and draperies. This study consisted of the laboratory test for thermal transmittance of selected fabrics and the exploratory survey for consumer perceptions towards curtains and draperies. The objectives of the laboratory test were to measure fabric's thermal transmittance, thickness, and count which affect to the effect in heat controlling. Selected 23 fabrics were tested at Korean Yarn and Fabrics Testing Inspection Institute. The objectives of the exploratory survey were to determine sociodemographic factors; the stage of family life cycle, the economics status, and homemaker's level of education, and physical factors; the type of houses, the direction of windows, and the type of windows, affect consumer perceptions toward curtains and draperies. Questionaires were administered to 489 homemakers selected by a stratified propotional sampling plan, in Seoul in October, 1981. Data from responses were analyzed by T-test(Analysis of Varience) and Partial Correlation. The major findings are as follows; 1. The results of the laboratory test 1) The fabrics used for draperies had higher effect in heat controlling than the fabrics used for glass curtains. 2) It did not show much differences among the fibers in heat controlling. The thicker fibers, however, had the higher effect in heat controlling among same fibers. 3) The fabrics which had high level of effect I heat controlling were corduroy, flax, rayon, nylon, acetate, thick polyester, and thick polyacrylic. The fabrics which had midium level of affect in heat controlling were velveteen, velvet, and thin polyester. The fabrics which had low level of effect in heat controlling were cotton, silk, and thin polyarcylic. 4) The draperies with lining showed 2∼5 times more effective in heat controlling than the draperies without lining. 2. The results of the exploratory survey Consumer perceptions towards curtains and draperies consisted of functional, financial, and aesthetic perception. 1) Factor affecting functional perception towards curtains and draperies was the stage of family life cycle. Families in the contracting stage considered function of curtains and draperies significantly better than those in others stages. 2) Factors affecting financial perception towards curtains and draperies were the economic status, homemaker's level of education, the direction of windows, and the type of windows. However the correlation between the factors and financial perception was too low to explain the significance of tendency. 3) There was not any factors affecting aesthetic perception towards curtains and draperies.

  • 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.

  • Fabrics created unique features through the change in various ways depending on the elements including fabric structure, threads, thickness, weaving, patterns and processing. This study examined the difference between texture and image depending on components of fabrics. In order to understand the trend of components of fabrics, the actual components of fabrics was analyzed by year, using the women's apparel trend books, Nelly Rodi Fabrics and Promostyl Fabrics. This study analyzed Spring/Summer season and Fall/Winter season from 2002 to 2012. Frequency analysis, cross-tabulation analysis, multiple response cross tabulation analysis were implemented using SPSS 18.0. The followings are the analysis results. For fabric composition, Spring/Summer season used cotton fabric the most. Cotton fabric accounted for relatively high usage in 2005, 2007 and 2008. Fall/Winter season used wool the most in 2002, 2003, 2004 and 2005. In case of fiber blend by fabric composition, cotton was blended with other fibers in Spring/Summer season except wool. The fiber blending ratio of wool was the highest in Fall/Winter season. Wool was blended in most fabrics. More than two patterns were mixed for fabric patterns. The fabric patterns were applied the most in 2012. For fabric processing, the fabrics by sensitivity-functional processing were continuously used every year and the surface finish showed relatively high usage in 2002 and 2011. In conclusion, this study will build the systematic data for 11 years including fabric trends in the past. It can improve specialization, systematization and efficiency in fabric planning.

  • This study comparatively analyzed the changes in the dimensional stability and the mechanical properties of stretch knit fabrics associated with washings conditions in order to determine the most appropriate washing method. Polyester and spandex knit fabrics were washed 25 cycles with nine washing condition profiles that controled detergent, hardness. temperature and RPM. The knit fabrics with repeated washings were evaluated by dimensional stability and measured by the KES-FB system. Polyester and spandex fibers have good chemical resistance. However, the changes in the dimensional stability and the mechanical properties were observed in washed knit fabrics. After repeated washings, the knit fabrics washed in an alkali or neutral detergent had good dimensional stability compared with the knit fabric washed in functional detergent. The washed knit fabrics were extended, stiff, rough, and had a smaller volume. The changes were the result of the rearrange of polyester fibers which twisted around spandex core and chemical interactions involving the detergent and the physical and mechanical forces of washing. Especially, using an alkali detergent resulted in increased stiffness and roughness of the knit fabric. In conclusion, the washing in water with low hardness and a neutral detergent can minimize the changes in dimensional stability and mechanical properties of polyester and spandex knit fabric.

  • Polyester(PET) fabrics were treated by corona discharge equipment with the small amount of flame retardants to enhance flame retardancy. The surface properties of corona discharged fabrics were investigated using water penetration time, SEM, ESCA, and TGA. When corona discharge was applied to PET fabrics, the flame retardants were evenly distributed. As a result, the oxygen-containing functional groups were produced, and the LOI value increased. Thermogravimetric analysis indicated that the flame retardancy was operative by gas-phase mechanism.

  • In order to introduce new functions onto textile fabrics, nylon and cotton were treated with green tea extracts. And then the anti-oxidant activity of fabrics treated with the extracts was evaluated by Blois method using DPPH ($\alpha$, $\alpha$-diphenyl- $\beta$-picrylhydrazyl). The anti-oxidant activity was exhibited on the textile fabrics treated as well as by the extracts itself. The cotton fabric treated with 10% o.w.f. of extract appeared to have almost 90% of anti-oxidant activity and 95% was obtained for nylon.
