study the dyeability(ΔE value) and color depth of silk fabrics dyed with Impatiens balsamina extracts. its flower, leaf and stem was extracted by water.This paper investigated some experiments under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH with silk fabrics dyed with Impatiens balsamina extracts.The results obtained were as follows1. It was found that λmax. of silk fabrics dyed with Impatiens balsamina extract was 260㎚ and its flower, leaf , stem and different colored flower(white, pink, violet) had same λmax at 260㎚.2. △E values were increased when dyeing temperature, repetition of dyeing and time was higher, value of munsell of silk fabrics dyed with Impatiens balsamina extract was Yellow-Red. But dyeing temperature, repetition of dyeing and time was higher, shifted to longer wavelenth side.3. Silk fabric dyed with Impatiens balsamina extracts at acidic pH was colored reddish Yellow-Red, alkali bath colored yellowish Yellow-Red in silk fabrics dyed with Impatiens balsamina extract.

effect of pasting agent on the defibrillation of Tencel fabric was investigated. It was evaluated by the weigth loss of fabric when the fabic was treated with cellulase containing various kinds of pasting agents. The surface appearance of Tencel fabric was checked by SEM. Under the treatment condition without pasting agent, the weight loss of fabric was high at pH 5.0 and 60℃. This means that the cellulase activity was high at this condition. By increasing the concentration of carboxymethyl cellulose(CMC), the weight loss of fabric was decreased monotonously. This tendency was not appeared in other pasting agents. CMC is synthesized by the reaction of chloroacetic acid and cellulose. The glucose units may be remained after the reaction. So, it was considered that the degradation of glucose unit in Tencel was decreased, because cellulase had to attack both Tencel and CMC.

liquor was extracted from flowers, leaves and stems of balsamine. Dyeing properties, colorfastness and antibacterial activities of the fabrics dyed with the balsamine extracts were investigated at a variety of dyeing conditions of differing pH, time and temperature.Wool, silk and nylon fabrics showed better dyeability than cellulosic fabrics, i.e. cotton, linen and rayon. Especially, nylon fabrics showed the highest K/S values. The dye-uptake was achieved to the highest degree during the first ten minutes of dyeing procedure. All fabrics were dyed well at 40℃ with no pH adjustment. The pH of unadjusted balsamine extracts was 4.6.Their colorfastnesses to washing, drycleaning and perspiration were good as 4 or 4-5 grade, but the light fastnesses were poor as 1-2 grade. While, the antibacterial activities to Staphylococcus aureus and Klebsiella pneumoniae were excellent with 99.9% of colonies reduction ratio. Their excellent antibacterial activity was kept well after ten times washing.
