The purpose of this study was to explore the consumers' purchasing pattern and dissatisfaction with the quality of the jean pants. A total of 695 men and women completed the questionnaire. The questionnaire for the survey measured consumer's jean pants purchasing pattern and dissatisfaction for quality. The results of this study showed that men bought higher priced jeans. Women in their twenties purchased and worn jeans frequently and men and women in age 20s mainly bought jeans at wholesale stores or department stores; but, majority of subjects in their thirties bought jeans at discount stores. Consumer's dissatisfaction with the quality of jean pants was significantly different among the groups by age, gender or their pursuing buying benefit. The men and women in age 30s were dissatisfied with harshness of the denim fabric. The subjects, who highly concerned on the aesthetic value, were dissatisfied with the inconsistence color of the jean pants after washing. Men and women who valued the functional performance of jean pants, were dissatisfied with low sweat absorbancy of jean pants material. The results of this study showed that the consumer's buying pattern for jean pants were differentiated by their age and gender. These results imply that jean pants manufacturers should develop jean pants to meet the needs of their target market. The jean pants, which were manufactured for discount stores, should be made of fabrics with good sweat absorbancy and soft hand. The fashion jean pants, which were targeted for women seeking aesthetic values, should be improved to maintain color consistency of the fabric.

The purpose of this study was to compare the comfort sensation depending on four different kinds of denim blue jeans: cotton, cotton/tencel, tencel, cotton/pp. The objective and subjective experiments were conducted to measure the comfort of blue jeans. To investigate the objective comfort, physical properties related to thermal insulation, moisture properties and hand were measured. For subjective comfort measurement, 5 healthy female college students were taken as subjects. The outcomes of the experiments are as follows: The higher the air permeability and bulk density of the denim, the lower the thermal insulation, the thicker the denim, the higher the thermal insulation. Tencel blending denim showed the higher bulk density, the lower air contents, and consequently the lower thermal insulation than the other denims. Tencel showed the highest moisture regain, and cotton/tencel blend showed the highest water vapor permeability. Tencel denim had relatively better flexibility, shape stability and elastic recovery than the other denims. The total hand values of the denims by KES-FB system were not significantly different. Cotton and cotton/pp denims raised the subjects body temperature after excercise more than tencel or cotton/tencel denims. Average skin temperature was found to have a correlation with micro climate temperature and micro climate humidity. The correlation coefficients were 0.749 and 0.767, respectively. However, average skin temperatures were not significantly different among the materials. Pulse rate was found to be the highest when wearing cotton/pp and the lowest in case of cotton/tencel denim. The energy was consumed in order of cotton>cotton/pp>tencel>cotton/tencel. There was no significant difference in preference before excercise, but, after the excercise, the order of preference changed as the following; cotton/tencel>tencel>cotton/pp>cotton.

This study presented a making method of jeans pattern with high fitness after deriving the appropriate shrinkage rate by material and washing process. For this purpose of this study, 6 jeans have been tested after washing finishing and we turned out appropriate shrinkage rate by evaluating the exterior of jeans and usage satisfaction. Then, a making method of jeans pattern was presented after applying the optimized shrinkage rate. According to the result of the exterior evaluation of test jeans, all 6 jeans were rated high with scores close to 3.5. Following the evaluation of satisfaction of usage by physical movement, the highest ranking was in the order of walking with normal steps, back bending $90^{\circ}$, chair sitting, climbing stairs, and squatting. The shrinkage rate by physical area showed the highest score in the order of pants length, waist circumference, thigh circumference, knee circumference, hem circumference, hips circumference. In addition, the shrinkage rate was higher in warp direction than weft direction after washing finishing. As for the result of addition and reduction of pattern measurements by parts of jeans, waist circumference was 2.6${\sim}$5.2cm, hips circumference was 1.3${\sim}$4.2cm, thigh circumference was 0.8${\sim}$3.1cm and knee circumference was 0.7${\sim}$2.5cm. Also, hem circumference was 0.5${\sim}$1.8cm and pants length was 4.0${\sim}$6.2cm. That is, this results showed a wide range of addition and reduction according to material and washing finishing.

The purpose of this study is to provide information on how to improving wearing sensation and fit of boots-cut jean through analysis of the actual wearing conditions and dissatisfaction. In order to compile the information about dissatisfaction with the appropriateness of the fit of boots-cut jean, a questionnaire was administered to 150 females(between the ages of 20 and 39) living in Gwang-ju, analyzed using the SPSS WIN 12.0 program. Also, 6 blue jean manufactures were investigated, the study method was a interview about company present status, sizing system and pattern of boots-cut jean. The result of this study were as follow: 1. In wearing conditions, the 20's(51.6%) to 30's(69.1%) is found the best preferred jean is boots-cut style. The reason why consumers prefer boots-cut jeans with wearing fit does to seem charming bodyline of the adult female. 2. Body type groups by drop was classified with the usual waist, the thick waist, the thin waist. The differences among age groups, body type and so on were compared using the chi-square test. Dissatisfaction of the fit of the thick waist and the thin waist was higher than the usual waist. 3. Research on the production sizing system of 6 blue jean brands showed the total sizing system of each manufacture were $3{\sim}9$, they were reflected the sizing system of the korean Industrial Standards(KS K 0051). Therefore, it is considered necessary for boots-cut jeans pattern and sizing system for Korean consumer's body shape.

The product evaluation and purchasing behavior of US brand jeans have been studied. The intrinsic and extrinsic cues are usually adopted to interpret the purchasing decison making processes. Among extrinsic cues price and brand name have been studied exten-sively but country-of-origin has not been examined in Korea. With the liberalization of retail industry foreign brands are aggressively penetrating in Korean pparel market. Since the penetration of imported apparel has increased tremendously lately the consumer attitude toward foreign produced clothing has great importance. The findings of the study were 1) Price was the most important among extrinsic cues ex-cept quality. Brand name was more important than store and country-of-origin. 2) The country image had significant influence to the preference as apparel production country. 3) The evaluation and willingness to buy of the jeans were greatly influenced by the be-havioral charcteristics of consumer variables. 4) The model to predict the willingness to buy of the jeans has been developed.

Denims were treated with neutral cellulase, acid cellulase, stone, and stone-neutral cellulase respectively at different cellulase concentrations varying treatment times in rotary washer. The effect of washing on denim was estimated by the changes in weight, color, back staining, tear strength, flex stiffness, and surface characteristics. Also the comparison of neutral cellulase, acid cellulase, stone, and stone-neutral cellulase washings was studied. Washing removes surface fibers and provides weight loss, color difference, back staining, and a decrease in tear strength and in flex stiffness. Stone-neutral cellulase washing and acid cellulase washing have a larger washing effect than neutral cellulase washing and stone washing.
