In this study, 12 azo disperse dyes based on phthalimide were synthesized including their precursors. The chemical structures of the dyes and the corresponding precursors were analyzed by the GC-MASS, $^1H$ NMR spectra and elemental analysis. The dyeability on PET, such as step dyeing and build-up properties and color fastness were examined using conventional exhaust dyeing procedures.

Nowadays, terms such as 'Smart Textile', 'Intelligent Textile' and 'Wearable Computing' are commonly used in everyday contexts. And radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. These products are required technologies which are textile treatments, printing, ink, etc. Durability of textile substrates is an essential marker for conductive ink printing process. Especially, heat stability is important, since conductive ink should be processable (annealing, curing) at temperatures below $150^{\circ}C$. This study was application of RFID on textiles. The textile pre-treatment processes should be carried out to use RFID antenna on textiles.

Charcoal dyed fabrics have been widely used in home textiles and functional clothing due to their anti-statics, antibacterial, deodorization, far infrared emitting and anion releasing. Soybean fiber were regenerated from soybean. Soybean fiber have biodegradable, microbiocidal, non-allergic, and anti-ageing properties. The purpose of this study is to investigate the dyeing characteristics of soybean fabric using charcoal as colorants. Soybean fabrics were dyed with charcoal solution according to concentration of charcoal, dyeing temperature, and dyeing time. To improve washing fastness and investigate mordanting condition, soybean fabric and dyed soybean fabric with charcoal were mordanted by mordanting agents such as $CH_3COOH$(acetic acid), NaCl(sodium chloride) and $AlK(SO_4)_2{\cdot}12H_2O$(Aluminium Potassium Sulfate). Dyeability and color characteristics of charcoal dyed soybean fabric were obtained by computer color matching and SEM morphology analysis. Particle size of charcoal and color fastness were also investigated. The results obtained were as follows; Mean average diameter of charcoal was $1.39{\mu}m$. The dyeability of soybean fabric using charcoal as colorants was increased gradually with increasing concentration of charcoal dyeing solution and saturated at about 8%(o.w.b.). The optimum dyeing temperature and dyeing time were $90{\sim}105^{\circ}C$ and 60~90 minutes respectively. The overall wash fastness at dyeing concentration 2~4%(o.w.b.) and 6~10%(o.w.b.) were 4 degree and 3-4 degree respectively. The fastness to washing according to mordanting method indicated good grade result as more than 4 degree in all conditions. On the other hand, the staining of adjacent fabrics, i.e. PET, Acryl, Wool, Acetate, Nylon and Cotton was found to be of grade 4 or 4-5 in all conditions.

With evolution in the production environment of the textile industry, the need for non-water-based dyeing technologies and eco-friendly process facilities in the dyeing and processing stages has increased. In recent years, supercritical fluid dyes have been developed and commercialized in Europe, centering on this demand. However, so far, such dyes have been mainly applied in the processing of PET fibers. Basic research has mainly involved investigation of dyeing by supercritical carbon dioxide or solubility of such dyes, and more in-depth research should be continuously carried out. In this review, we describe the types and characteristics of supercritical fluids that exhibit specific properties at pressures and temperatures over the critical point. In addition, the state of the art in the dyeing and processing technology using supercritical fluids and associated, processing problems, environmental regulation, and wastewater treatment issues are described in detail. We hope this review can contribute to the supercritical fluid technology being further developed as an environment friendly dyeing processing method. Furthermore, we expect that the technique can be used as a means of ensuring different, high-quality dyed products.
