This study was carried out on the physical properties of the lining fabrics. When the lining fabrics are rubbed against outer fabrics, the electrostatic charge and frictional noise are generated. Electrostatic charging impairs the draperies and soil resist-property of fabrics. And frictional noise also impairs the wearable property of garments. Measurements of the electrostatic charging, frictional noise and slipness were made for twelve lining fabrics made of three weaves and four kinds of yarns. The conclusions of experiments are; 1. Polyamide lining fabrics were not suitable for use and viscose rayon lining fabrics were suited to be a lining of garment. 2. Twill weave lining fabrics had the least slipness values and only polyamide lining fabrics were charged when they were rubbed with each other. 3. The starched lining fabrics had more frictional noise than unstarched.

Thermal resistivity is an important factor in the body-clothing-ambient system to provide protection of body from the environmental condition. This paper intended to investigate the relationship between thermal resistivity of the body-clothing-ambient system and the thickness of the air spaces in the system. For this investigation, the authors made a testing apparatus of a cylindrical heater of constant temperature to simulate the body-clothing-ambient system. Five cotton plain fabrics of different fractional fabric cover and their P.V.C. film coated fabrics were used for specimens. Specimens were shaped a cylinder form to simulate the sleeve of cloth and heat losses of the cylinder covered by specimens were measured. The experimental results were converted into clo unit, and the relation between thickness of air spaces in the system and total thermal resistivity were analysed. The conclusion of this study were followings: 1. For good thermal resistivity, it is better to make air spaces in the body-clothing-ambient system. 2. The maximum thermal resistivity was shown when the thickness of air space between the body and clothing or between clothings was 16mm. 3. When total thickness of the air spaces in the body-clothing-ambient system was constant, the maximum thermal resistivity was shown when air spaces in the system were equal. 4. When the thicknesses of each air spaces were equal, the equation for thermal resistivity became as follow. Y=0.21658Z+0.1150630e-X, x0.016-679.9(x-0.016)2+0.14108 Y: stands for thermal resistivity in clo. X: stands for air space in m. Z: stands for fractional fabric cover.

Si-ro-set process produce permanent pleats effect. In this respect 3 kinds of wool fabrics treated in 2 kinds of hair permanent agents, and was investigated wheter this treatment can apply easyly for domestic finishing or not. The result of this study were as follows ; 1. It was available for permanent pleats effect by treating the wool fabrics in hair permanent agent. 2. Color fastness was good to the liquid. 3. Wool fabrics weakened when it was pressed at high temperature for a long time. It was good for pressing at 50℃ for 60 min. 4. Pleat effect was better when it soaked in Systein. 5. Thin fabrics were better effect than thick one.

This research was conducted to establish the efficient use of the colored rice bran for dyeing textiles. To investigate the fabric dyeability of the colored rice bran extract, the anthocyanin pigments were extracted with water of different temperature ranges of 40∼80℃ and were dyed on silk fabrics with different dyeing temperature 25℃∼60℃, at acidic pH and neutral pH, respectively. Aluminum chloride was pretreated with mordant. K/S value and dyeing fastness of dyed silk fabrics were examined The anthocyanins of the colored rice bran were stable and red color at acidic pH, red purple or purple blue at neutral pH, but unstable, blue color at alkaline pH. If extracting temperature and dyeing temperature of dyeing solution were higher, the dyeability was high, but the color of dyed fabric showed red tone. When extracting temperature was 80℃ and dyeing temperature of dyeing solution was 60℃, the dyeability was best. Without mordant, the dyeability of silk fabrics was higher in acidic pH than in neutral pH solution. With mordant, the dyeability was higher than without mordant, and also higher in acidic pH. Pretreatment of aluminum chloride resulted in the increase of color intensity and stablility. The laundering fastness of dyed fabrics was good from grade 5 to grade 3-4. Because of the anthocyanins sensitivity on light radiation, the light fastness of dyed fabrics was poor from grade 3 to grade 1-2.

The purpose of this study was to confirm the difference of garment pressure and comfort depend on age group wearing the Korean skirt-band. A loadcell was used for measuring garment pressure, and 25 female subjects were chosen for each of young, middle, and old age groups. Garment pressure was measured in front, side, and back parts of the body. The results were as follows: 1. The younger the subjects, the greater the garment pressure. This suggests that the young age group wear the Korean skirt-band more tightly than needed. 2. The measurements of the pressure in 3 parts of the body were different. In young and middle age groups, pressure decreased from side to back, while in the old age group the order was side, back, and front. 3. The young age group felt high restriction of pressure. And the pressure in side part of body is the greatest among the three measurement.
