The hydrolysis of some vinylsulfonyl (VS) typed reactive dyes were investigated at the pH, temperature and other experimental conditions. The hydrolytic behaviour, especially, stability in various pH value, of the water soluble reactive dyes are examined. In neutral and acid condition, mother dyes are a quite stable. Other hand, it was found that dimerization and decomposition for these dyes were estimated in an aqueous alkaline medium. These alkaline hydrolysis behaviour was monitored by the high performance liquid chromatography.

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.

Entering the period of Mass Customization, and with the help of the Digital Textile Printing technology, the purpose of this study is to propose two customer involved design process models, based on the Digital Textile Printing technology, and to compare their efficiencies and appropriateness with those of the existing design process model, which would lead us to discover the possibilities of Mass Customized design process. By the result obtained from the survey of 166 females in their twenties and thirties, the second Mass Customized design process model which gave most choices to prosumers was preferred the most, while the existing design process which gave no choice seemed to be preferred the least, and among the design elements of textile, color appeared to be the most significant influential factor in the preference of the clothing by the consumers. In summary, it appeared that every aspect of the society requires a shift in the process of the thought from Mass Production to Mass Customization at this point, and a guideline was made from the Mass Customized design process suggested in this study.

Poly(ethylene terephthalate) (PET) fabrics were treated with a silica particle and phosphate flame retardant to determine the optimum process condition of the digital textile printing(DTP) media. The treating conditions for the study were 6 conditions, from F1 to F6, in which F3, F4 and F5 were treated with mixture of both silica particle and phosphate compound in process of pad, dry and cure fixation. F6 was treated with phosphate compound only and silica particle coating successively. Xanthan gum was used to control the migration of liquid phosphate compound onto PET fabrics. The change in surface morphology of fabrics treated with silica particle and phosphate compound was observed by SEM and flame retardance was evaluated by limiting oxygen index(LOI). It was observed that F6 was the excellent flame retardance and low bleeding in printing, Collectively, the printing characteristics of silica to cyan, magenta, yellow and black ink and flame retardance of fabrics finished with phosphate compound were identified in this study.

For high quality DTP products, it is important to optimize the parameters of media, pre- and after-treatment, ink, printer, etc. This study investigated the effect of types of fabrics(media) as a DTP parameters. Especially, the effects of media properties such as yarn twist and knitted fabric structure, on printability and color difference were examined. Two types of cotton yarn twist(830 and 1630 twist/meter) and five knitted structures of media were prepared with a single circular knitting machine. The K/S values of hard-twist samples were higher than those of normal-twist samples in every media structures. It is more effective to use the knitted fabrics of a hard-twist yarn to obtain dark color in the printing above input level value 60 where the printability improvement was most pronounced in case of plain structure. Among the five media structures a plain structure was the highest and that of corduroy was the lowest in terms of K/S values. Also ${\Delta}E$ values and lightness of the hard-twist yarn samples were smaller than that of normal-twist yarn samples when ${\Delta}E$ values were tested by using a standard of a normal twist yarn sample with a plain structure, which was increased in the case of corduroy structure.

Digital printing has been used in various industrial areas, including semiconductor manufacturing and textile printing. However, implications on ceramic textile have not been well established so far. Printing high-viscosity materials requires an understanding of their behavior. An inorganic high viscous material with a viscosity range of 20-30 cps is analyzed using a viscometer and through X-ray diffraction. In this study, a digital printer is designed and assembled using a high-viscosity material with software for PC control, resulting in reduced processing at a fast area velocity of $20m^2/hr$. The present study demonstrated that the printer is capable of controlling the shape of the drop mass to smear ink smoothly onto the ceramic surface under an economic budget. In addition, to avoid any difficulty in color management, the ceramic printer is equipped with an independent color management system designed to cope with images on a highly viscous material.
