Polyethylene Terephthalate (PET) has been used as a mainstream fiber to make silklike fiber. The silky characteristics such as softness, dry touch feeling and flexibility can be obtained by weight reduction treatment. In aqueous alkali solution, the surface of PET is dissolved away and reduced in weight. The PET fiber, yarn and fabric become thinner and the gaps between fibers are wider. Its mobility is greatly improved without change of basic structures of the treated PET fibrics. The alkali treatment was conducted under the various experimental conditions such as alkali (NaOH) concentration, treatment time and temperature. As the weight loss increased, drapability improved and tensile strength remarkably reduced. When the PET fabrics lost 30% in their weight, drape coefficient lowered as much as 30oA and tensile stregth lowered as much as 50%. The weight loss over 30% brings great improvement in drapability and dyeability and significant decline in durability. By the alkali treatment, absorbency in spectrophotometer of dyed PET can be increased as much as 82% due to the increase of the surface area and formation of microvoids on the surface.

We intend an empirical assessment of examining the differences in the appearance management behaviors and demographic variables among groups classified by the clothing consumption values. The questionnaires are administered to 493 female and male adults above 20 years old in Seoul, Gyeonggi-do, Daegu and Kyungpook regions. For analysis of data from 478 respondents, descriptive statistics, cluster analysis, Cronbach's ${\alpha}$, ANOVA, Duncan test and ${\chi}^2$ test were applied. We show the following results. First, Factor analyses were employed for the clothing consumption values and appearance management behaviors. Six factors were for clothing consumption values: Individuality, appearance attractive, social, functional, conditional and fashion clothing consumption value. Four factors were for appearance management behaviors: weight training, skin care, hair care, make-up and clothing selection. According to clothing consumption values, four groups were classified: the passive, functional, social, and active group. We did cluster analysis to the appearance management behaviors of weight training, skin care, hair care, make-up and clothing selection. Second, the social and active groups were more interested in individuality, appearance attractive, social, functional, conditional and fashion clothing value. And they were also more involved in appearance management behaviors. Third, among the demographic variables, the single and female in 20s and 30s with higher level of education belonged to the active group. In this contribution, we find significant differences in the appearance management behavior and demographic variables classified by the clothing consumption values.

The purpose of this study was to investigate the effects of silt ventilation system on physiological responses. We measured rectal temperature, local skin temperature, clothing microclimate, blood pressure, heart rate, energy metabolism, body weight loss and subjective sensation during 70 minute, 50 min exercise period and 20 min rest period. The five women subjects randomly wore sportswear without slit ventilation system(NS sportswear) and sportswear with slit ventilation system(S sportswear) under the environmental condition of $25^{\circ}C$, 50%RH. The results of this study are as follows; Rectal temperature, mean skin temperature, clothing microclimate, blood pressure, heart rate, energy metabolism and body weight loss were significantly lower level in 'S sportswear'. In 'S sportswear', subjects replied less hot, less uncomfortable and less wet. Slit ventilation system can be used for bellow effect which is meaningful device of convection during exercise. We could find out that 'S sportswear' has advantage in physiological function.

This study investigated the relationships among cognitive age, sociocultural attitudes towards appearance, and appearance management behaviors. This study gave a questionnaire survey to adults between the ages of 17 and 76 who lived in the Daegu and Gyeongbuk regions of South Korea. Data collected from the 296 respondents were analyzed using descriptive statistics, correlation analyses, and ANOVA. The sociocultural attitudes towards appearance (awareness and internalization) were significantly correlated with appearance management behaviors (weight training, skin care, hair care, make-up, and clothing selection). The cognitive age was significantly correlated with the sociocultural attitudes towards appearance and appearance management behaviors such as weight training and clothing selection.

This research analyzes characterization and classification of body types for the Chinese women with body measurement values. The measurement has gauged in 1999 in Beijing Institute of Clothing Technology in China. 100 women of the Chinese college women aged 17 and 24 in China were measured for this research. In the results of frequency analysis, the tall of Chinese women were 158.37㎝ and also has less than 150㎝ high, and has thick under bust circumference, and has a group of more than 18㎝ for width of nipple. In the results of factor analysis, Factor 1 represented the degree of abesity, while factor 2 indicated the stature and the arm length. The body types are classified into five types by cluster analysis. The stature and weight varied according to types, leading to a classification focusing on the body size determined by stature and weight factors.

This study explored elderly American women's body satisfaction and clothing consciousness with the methods of survey and body measurement. To that end, I first investigated their self-perception of body size and body satisfaction and also the relationships between those, along with the relationships between body measurements and body satisfaction. Then, I analyzed the differences in elderly women's body satisfaction and clothing consciousness among different body type groups. For the last, I examined the degree of their body thinness or obesity and ideal body size in order to explore the standard for ideal body shape among elderly women. Elderly American women were satisfied with most of their body parts except waist circumference and weight. Body satisfaction with stature, weight, and hip circumference was correlated to both size perception and body measurement. Body satisfaction with thigh circumference and leg length was correlated to size perception, and also that with waist circumference and neck length to body measurement. Size perception showed differences among body types, but body satisfaction did not show notable differences among body types. There were significant differences between real size and ideal one. Elderly American women thought that clothing was important in their everyday life.

The purpose of this study was to find out the effect of color, tone, perceiver's gender on image perception of natural dyeing of cotton and mosi. The experimental materials developed for this study were a set of stimuli and response scale(The 7-point semantic). The stimuli was 20 fabrics manipulated with two kinds of fabrics(cotton, mosi), five colors(red, yellow, blue, green, purple) and two tone variations. The subjects were 412 adults in Daejeon and Kongju. The results were as follows: The perceived image of the stimulus material consisted of 4 dimensions (attractive, conspicuous, hand, weight) colors, tons, materials as well as perceiver's gender affected on some selected image dimensions color affected on the four image dimensions, tone affected on the conspicuous, hand and weight images, materials affected on the attractive and hand image and perceiver's gender affected on the weight image. Interaction effects existed among colors, tons and materials on the conspicuous image. In conclusion the results support gestalt theory in which the sum of the parts is bigger than the whole and design strategies for the Mosi fabrics should be developed on the basis of persuited design image as well as target consumers.

The purpose of this study is to measure, compare, and investigate the physical properties of rayon/cotton blend fabrics treated with cellulase and cellulase & specific degeneration silicon and to present basic data which is in development a value-added fabric. The results are as follows. The condition for the treatment of cellulase was at 55$^{\circ}C$, pH 4 and the weight loss increased as the concentration of cellulase and the treated time increased. On treatment with cellulase, the crossectional view & longitudinal view of fiber noticed remarkable crack as weight loss increased and tensile strength and elongation decreased, and pilling was enhanced remarkably. KOSHI was increased, NUMERI and FUKURAMI were decreased as weight loss increased. In the basic characteristic value of clothing wearning, shape stability and drapability were decreased, but air content was improved. On treatment with cellulase & silicon, the degree of damage in the crossectional view & longitudinal view of the fiber reduced. Tensile strength, elongation, moisture regain improved. KOSHI and FUKURAMI were reduced, NUMERI was improved rather than when it was treated with cellulase. Therefore handle was improved. In the basic characteristic value of the clothing wearing, shape stability, air content, drapability were improved.

The purpose of this study was to examine the relationship between weight of fabrics and texture and sensibility and preference of consumers for F/W women's jacket fabrics. Structural Equation Model(SEM) using AMOS program was conducted to analyze the relationships. Then, this study aimed to provide useful information in planning designing fabrics through predicting the subjective characteristics analyzed. The main survey was developed the 7-point semantic differential scale of subjective texture, sensibility and preference. Fifty trained female panelists of 20-30 years old were participated and questionnaire method was used with 20 kind of fabric. The evaluation methods such as by the sense of sight & touch were used when fabrics were estimated subjectively. When evaluated by the sense of sight & touch, fabric's weight did not have effect directly on preference, but had effect indirectly on preference through the texture and the sensibility..

The purpose of this study was to investigate the effects of narcissistic personality and self-esteem on the appearance management behaviors(weight, skin care, makeup, hair care, clothing selection) of female college students. The questionnaires were administrated to 362 female college students living in Gwang-ju city, Korea. For analysis of data, descriptive statistics, factor analysis, Cronbach'$\alpha$, regression analysis were applied. The results were summarized as follows. First. the female college students' narcissistic personality was categorized into four factors, need for administration, leadership/self-confidence, need for power/entitlement, and superiority. Second, narcissistic personality significantly influenced appearance management behaviors. The further examination of the effects showed that need for administration appeared to affect clothing selection, hair care, skin care, makeup, and weight. Third, self-esteem turned out to have positive effects on overall appearance management behaviors. The further examination of the effects showed that self-esteem appeared to affect clothing selection, skin care, hair care, makeup, and weight. The results indicated that female college students' narcissistic personality and self-esteem were important factors to their appearance management behaviors and marketing programs for fashion industries.
