초록

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.
