To study the dyeability(K/S value) and surface color of silk fabrics dyed with Impatiens balsamina extract, its flower, leaf and stem, was extracted by water.This paper investigated some experiments with Impatiens balsamina extract under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH with silk fabrics.The results obtained were as follows.1. It was found that λmax. of silk fabrics dyed with Impatiens balsamina extract was 260㎚ and its flower, leaf, stem and flowers(white, pink, violet) had same λmax at 260㎚.2. K/S value was 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. dyeing temperature, repetition of dyeing and time was higher, shifted to longer wavelength side.3. pH added acetic acid was colored reddish yellow-red, but pH added alum was colored yellowish yellow-red in silk fabrics dyed with Impatiens balsamina extract and repetition of dyeing was increased the dye-uptake.

This research aimed at scrutinizing the comparative dyeability of some disperse dyes at low temperature on ultra-microfiber polyester, islands in the sea type (0.05 denier), which has claimed utmost fastness and improved uptake of dyeing. Comparisons of dyeability, such as rate of dyeing and color depth, on ultra-microfiber polyester were evaluated by H.T. exhaust dyeing method and followed by the test of rubbing fastness. To achieve high wet fastness, some commercial disperse dyes, Terasil WW and Megacron dyes, which have been recently launched for excellent wash fastness, have been examined compared with conventional disperse dyes, C.I Disperse Red 167 and C.I Disperse Orange 30.

In this research, we accomplished in order to improving color fastness of sublimation for Poly (vinyl alcohol) (PVA)-iodine polarized film. The poor iodine sublimation problem has greatly improved by O2 low temperature plasma treatment.We obtained the followings: (1) plasma treatment has contributed in adhesive ability via peel strength, AFM image and roughness were investigated, But the improvement in adhesive strength was not linearly proportional to the treatment time. (2) O2 plasma treated PVA-iodine polarized film was good enough as to maintain the transmittance and polarization even after iodine conc. of 0.05mol/L and dipping time of 50sec. (3) O2 low temperature plasma treated PVA-iodine polarized film has obtain high durability because of good adhesive strength.
