황토는 주로 가는 모래로 되어 있어서 다량의 석영, 장석, 운모 등 다양한 광물 입자로 구성되어 있고 탄산칼슘(CaCO₃), 철(Fe), 마그네슘(Mg), 나트륨(Na), 칼리(K) 등의 성분으로 되어 있다. 황토는 다양한 약성원소를 포함하고 있다. 그것은 특히 제독 능력을 높여줄 뿐 아니라 항균 작용도 하며, 지혈제인 동시에 응고제로 매우 뛰어난 치료효과를 보여준다. 황토의 효능은 숯의 효능과 다를 바가 없으며, 어느 것이 더 우월한 지에 대한 비교를 할 수 없을 정도로 그 약성에 있어서 유사하다. (중략)

The influence of the concetration of the discharging agent on some properties of silk fabric dyed with reactive dyes studied. The tensile strength, yellow index and whiteness were investigated as parameters to determine the effect of the dischanging agent. The results were summarized as follows ; 1. The tensile strength and the yellow index decreased with the increase of the concentration of the discharging agents. 2. The whiteness depended on both of the type and the concentration of the discharging agent.

섬유공업에서 거품의 이용은 1960년대 부직포의 제조에 처음 시도되었으며, 기술개발 및 연구는 1980년대에 이르러서야 이루어지기 시작하였다. 거품을 이용한 염색가공 공정은 low wet pick-up을 하므로 건조하는 동안 약제의 이동이 적어 보다 개선된 염색가공 효과를 얻을 수 있고, 종래의 습식공정과 비교할 때 처리액의 가열 및 건조에 소비되는 에너지를 절약할 수 있다. (중략)

This research study was performed to compare between Korean traditional color and digital transfer textile printing. This would help to find the new direction to apply Korean traditional colors to modern textile industry. The objective of this study is to digitalize Korean traditional colors to be applied to modern textiles, based on research studies by previous researchers, on the actualization of Korean traditional colors for textiles. The study focused on 21 red colors among others. Digital color palette of graphic program was printed on 6 different polyester textiles by using digital transfer textile printing. Different things to be supplemented were found by comparing the results with the colors of Korean traditional standard color names. After measuring the colors, Munsell color system and CIE $L^*a^*b^*$ value were measured then comparative study was performed on the measured values using 3D graphs. Measured colors of Munsell varied by color but in overall, chroma became low while brightness became high. Color characteristic of warm colors got weakened by turning into cold colors as brightness got high but yellow and red got low due to the characteristics of CIE $L^*a^*b^*$ value. This study has limitations with color analysis of digital transfer textile printing due to standardization of textiles and standardization of traditional colors however it can support to actualize the colors for the design using traditional color names by visualizing the color change of digital transfer textile printing in the future.

This study conducted a research on burn-out printing convergence technology for cellulose blend knit fabrics. Printing technology, which forms color pattern on the fabric, can be generally classified into four according to printer or printing method, e.g. screen printing, roller printing, rotary printing, digital printing. However, these printing methods are flat in design or pattern, which have limitation to overcome monotonousness of fabric, so that recently burn-out process method, which expresses three-dimensional pattern effect by treating chemical on the surface of fabric as the method to appeal its esthetics to the customers. Particularly, in case of cellulose/polyester composite material, first, it is proceeded in 2 processes, by dyeing cellulose or polyester fabric and burning out cellulose fabric, in this process, due to pollution caused by disperse dye migration, color of polyester fabric part could be discolored, which has high falt risk. This research considered coloring burn-out technique, which simultaneously proceed dyeing and burn-out by reducing dyeing and burn-out process to 1 stage, which were proceeded in 2 stages previously. As the research result, it was confirmed that reasonable depth of roller was 0.04~0.06mm in roller printing process, heat treatment condition of burn-out far-infrared radiation was $185^{\circ}C{\times}30m/min$. Color fastness to washing was confirmed to be 4-5 grade, color fastness to rubbing, 3-4 grade, color fastness to light, 4 grade. Also, it was confirmed that energy reduction effect appeared 38.19%, in case of energy cost per yard compared to the existing production, also, 19.74%, in case of production cost.

This study analyzed the recognition rate of QR codes printed by digital transfer textile printing for mobile application. The purpose was to identify conditions that increase recognition rates of QR codes printed on textile, in order to increase utility of QR codes in the textile and fashion industries. The study focused on differences in the color of the QR codes and denier, which is a unit of textile fineness measurement, of the textile on which the QR codes were printed. And the recognition rates of QR codes according to the color and denier were analyzed. According to the result of this study, the colors of QR codes had an effect on the recognition of the codes by mobile applications. Specifically, strong contrast, i.e., bright background and relatively dark module, increased the recognition rate of the QR codes. Digital transfer textile printing tend to change the hue of red and yellow and increase brightness, and change in the printed colors also had an effect on the recognition rate of QR codes. There was a clear difference in the color and recognition rate of the printed QR code according to the denier of the textile, and this suggests denier has an effect on the recognition rate. The findings in this study can provide basic data for future research on QR codes digital printed on textile.

This study was aimed to investigate the effects of visual texture on color emotion and to establish prediction models for color emotion by both physical color properties and visual texture characteristics. A variety of fabrics were printed by digital printer according to hue and tone combinations. Subjective sensation was evaluated in terms of visual texture for fabrics printed in gray whereas color emotion for those in chromatically printed. As results, fabric clusters by visual texture showed significant differences in color emotion factors and the differences were clearer for grayish tone fabrics. Prediction models for color emotion factors by both physical color properties and visual texture clusters were proposed as for all fabrics and grayish ones, respectively.

Aramid fibers have been widely used as the reinforcement for composites due to their high modulus and strength. Nowadays the safety measures is required to improve the personal protection. The dyeing of aramid fibers is considered to be very difficult and their dyeing mechanism is not well illucidated. Therefore, this study is to establish the dyeing & printing technology for aramid fibers. The effects of swelling agent and neutral salt in the dye bath on the obtained colors were studied. Also dyeing method of aramid fibers depending on dyeing temperature and dye concentration were established. Color fastness of the dyed aramid fabric with cationic dyes were acceptable excluding light fastness.

The purpose of this study is to obtain the dyed-fabrics of the elaborate patterns using the natural dye powders extracted from Galla Rhois, Sophorae Flos Immaturus, Clove, Sappan Wood, Madder, Log Wood and Japanese Green Alder. Specific informations on the separation and powder-making of each colorant were disclosed. Appropriate printing paste preparation and printing conditions including the viscosity and mordant concentration in the printing paste were investigated. The dyeability and colorfastness of the screen-printed silk fabrics with the colorant powders were discussed in terms of practical applicability. The deodorization and antimicrobial activities of the silk fabrics screen-printed with natural dyes were also assessed.

This study is to research on printing method by use of colorants extracted from Sappan wood. As for the research, the stability of paste added by mordants, steaming condition, optimal mordant concentration, change of surface color and colorfastness were measured. The experiment showed that guar gum were stability among the sodium-alginate, modified starch, guar gum. And the surface color was best when the streaming time was 60 minutes, mordant concentration 3g/l. And for colorfastness experiment, colorfastness to drycleaning was good, but colorfastness to light and colorfastness to washing showed no desirable result.
