In order to investigate the detergency effects of various detergents to stained polyester & cotton fabric with solid soils such as carbon black, liquid paraffin and fat, the optimum washing conditions according to the types of washing agent, the assesment of detergency effect by the measurement of reflectance after and before washing were studied. The detergency effect of various detergents to stained polyester and cotton fabric increased by using the mixtures of bleaching and enzyme detergent. In order to obtain the excellent detergency effect, 2-step treatment, the pre-washing with bleaching agent and bleaching-enzyme mixture detergent treatment is preferred. In comparison of the detergency to polyester and cotton fabric, it is assumed that the detergency to polyester stained fabric was superior than that to cotton stained fabric because of the difference of adhesive force between soil material and fabric in preparing solid stained fabric.

The natural dyeing of cotton fabric with Perilla frutescens var. acuta extract was investigated. The proper extraction temperature and time were $100^{\circ}C$ and 120 minutes. The proper temperature, time and colorant powder concentration for the dyeing of cotton fabric with Perilla frutescens var. acuta powder were $90^{\circ}C$, 60 minutes and 15%(o.w.b.), respectively. In various mordanted methods, the K/S values of simultaneous-mordanted methods were higher than those of pre-and post-mordanted methods. And the Cu-and Fe mordant showed higher K/S values than those of other mordants. Light colorfasness of mordanted cotton fabric was poor, but the other colorfasnesses were shown to be good. The cotton fabric mordanted with Cu mordant was showed effective bacterial reduction.

The Cotton fabric was dyed with various directd dyes, and then treated with copper sulfate or copper sulfate/thiourea. Munsell color system, dye exhaustion, tensile strength, light fastness, washing fastness and rubbing fastness were investigated for the treated fabrics. The results obtaind are as follows: 1. The color variation of the cotton-dyed fabric by aftertreatment with copper sulfate was shown redish, but original color with copper sulfate/thiourea. 2. Copper sulfate/thiourea was much more effective than copper sulfate only to increase the light fastness, washing fastness and rubbing fastness. 3. Dye exhaustion of the cotton-dyed fabric by aftertreatment with copper sulfate was decreased about 20% more than those of untreated. 4. Tensile stregth of cotton-dyed fabric by aftertreatment with copper sulfate/thiourea was decrease about 10% more than those of untreated.

Antimicrobial activity of silk and cotton fabrics dyed with gromwell colorants was examined by shake flask method. The effects of bacterial reduction rate on dye uptake and mordanting were explored. The silk(K/S value 8) and cotton fabric (K/S value 4) dyed with gromwell colorants showed high bacterial reduction rate of 99 % and 88 %, respectively. Post-mordanted silk fabric increased at K/S value, also showed higher bacterial reduction rate than unmordanted. But the effects of antimicrobial activity on mordants showed respectively different results. Pre-mordanted cotton fabric except Sn mordant increased at K/S value, but it was not significant. Pre-mordanted cotton fabric showed significantly higher bacterial reduction rate than unmordanted. Therefore, it was considered that dye uptake of cotton fabric dyed with gromwell colorants and mordants were involved in the bacterial reduction rate. It was concluded that gromwell colorants had antimicrobial activity.

This study investigated the flame retardant, anti-static property and wear comfort of knitted fabrics made of two kinds of composite yarns comprised of modacryl, antistatic PET, cotton and excel(R) fibers. A Low Oxygen Index (LOI) above 28 was observed in the modacryl knitted fabric specimens. The flame retardant was superior at the excel(R) fiber (including modacryl knitted fabric) than the one including cotton fiber. Anti-static properties of the modacryl knitted fabrics imbedded by 3wt% of antistatic PET fibers were observed by rubbing with wool fabric attached to the measuring apparatus, which showed a better anti-static property than the excel(R) fiber (including modacryl knitted fabric). Wear comfort indicated that quick perspiration absorption and the fast dry property of excel(R) (including modacryl knitted fabric) was better than one that included cotton fiber. Warmth keepability and breathability of the knitted fabrics indicated good results in the excel(R) (including cotton and the modacryl knitted fabrics). However, the tactile hand property of cotton fiber (including modacryl knitted fabric) was better than excel(R) fiber due to high extensibility and compressibility, and low bending and shear rigidity of the cotton fiber (including modacryl knitted fabrics).

We examined the antimicrobial effects of the cotton fabrics which were laundered at different conditions and treated with a colloidal silver solution using Staphylococcus aureus. Colloidal silver solution was made from commercial colloidal silver generator by electrolysis. The fabric which was innoculated and washed with water before drying had no more Staphylococcus aureus, but which was innoculated and dried before washing with detergent solution had lower reduction rate. The fabric washed with oxygen bleach did not have an antimicrobial effect, but rinsed with 0.07% fabric softener showed antimicrobial properties. The fabric rinsed with 0.7ppm colloidal silver solution had better antimicrobial effects. As the treating concentration of silver solution increased, the antimicrobial property of the fabric was increased. The fabric treated with 5% silver solution sustained reflectance and whiteness of untreated fabric. The colloidal silver treated fabric lost antimicrobial property after washing because nano-sized silver particles were located on uneven fiber surface without chemical bonding forces.

We prepared natural indigo/calcium hydroxide complex powder from tinctoria's leaf, according to the demand of developing new dyeing technique of natural fibre with natural indigo. FT- IR and UV/Visible spectra were operated to find the dyeing properties of synthetic indigo and natural indigo powder. Cotton, flax and silk fabrics were dyed with different pH, dye concentration and dyeing time. The colour yield of indigo dye was quite sensitive to dye bath pH and fabric. In synthetic indigo, the highest K/S value of dyed silk fabric was shown at near pH 9.0, and which of flax and cotton fabric were shown at pH 11.0. In other hand, in the case of natural indigo complex powder, the highest K/S value of dyed silk fabric was shown at near pH 8.0, and which of flax and cotton fabric were shown at pH 9.5∼pH 10. Mercerized cotton fabric dyed with natural indigo powder has a little antimicrobial activity.

The cotton fabric armour for lower class soldiers can be found from the historical records of the mid-Joseon Korea. And the records show that the form and the structure of the armour was modified in the late 19th century in order to provide better protection from gunshots for the soldiers in the midst of the invasions from the West. This is a survey and research of the only artifact of the cotton fabric armour remaining in Korea - for its form, dimensions, and design. Using the historical records as reference, we can confirm the structure and characteristics of the cotton fabric armour of the Joseon period. This cotton fabric armour, preserved in National Museum of Korea, is a vest-type armour made of 30 layers of cotton. On the right shoulder, there is a button for tying knots and strings were tied under both armpits. On the surface of the cotton fabric armour there were some characters and patterns stamped in black. Presently, this artifact in Korea is the only specimen relic of its sort, but there are some other related relics in foreign countries including helmets and belts. Continuous researches would help extend the scope of armour study beyond the traditional researches that only focuses on the armours of the officials, thus helping us to understand the military costumes in traditional Korea.
