  • In order to give a silk-like touch to PET fabrics, the PET fabrics were treated with NaOH alkaline solution in various conditions. In alkaline treatment, the liquor flow type pilot weight reduction apparatus with magnetostrictive ultrasonic transducer was used for the study. The effects of ultrasonic application, treatment time and temperature at NaOH 4% and 6"A solution on the decomposition rate of PET fabrics. From the results of the decomposition rate of PET fabrics, the qualitative and quantitative analysis of oligomer after decomposition of PET fabrics carried out by the HPLC. On the other hand, the surface pore characteristics of decomposition PET fabrics measured by porosimetery. The pore characteristics on the surface of treated PET fiber depended on the decomposition rate and did not depend on the ultrasonic cavitation. The pore diameter of alkaline untreated PET fiber were 15A and those of treated PET fibers were 5~6$\AA$ at the maximum pore volume. The average pore sizes of fiber before and after treatment were 141 h and 160h, respectively. Total amount of oligomer of the untreated PET fibers were 1.70wt% and 67.7% of total oligomer occupied with PET cyclic trimer and PET cyclic tetramer. Total amount of oligomer of fiber with 26.9% and 48.0% of weight loss without ultrasonic application were 1.78wt% and 1.79wt%, respectively. Also total amount oligomer of fibers which were reduced 27.7% and 48.2% of weight loss with ultrasonic application were 1.74wt%. This result showed that the removal rate of oligomer in the process of alkaline hydrolysis with ultrasonic higher than that of without ultrasonic application.tion.

  • Journal of the Korean Society of Clothing and Textiles Vol. 19, No. 1 (199i) p. 71~79 The authors study on the traditional textile production and the formal dress through the field research concerning the folk attitude toward dress style around the Mt. Kumo area. In this area, people produced and wove hemp, cotton, and silk except ramie. Because of poor production of raw materials, they produced textiles only for self-sufficiency. Every household dealt with dyeing on a small scale. In the past, people dyed cloth natually using plants as material. Natural dyeing, however, gradually changed into chemical one since the Japanese rule. The formal dresses, which people wore on particular occasions such as the hundredth day after child's brith, the first birthday, and traditional holidays, were very meager due to poor living standards. People could not see the formal dresses with full decoration. Bride and bridegroom were the village.owned wedding dresses, and if they could not afford to, they simply put cloth on to remember the occasion. People around the Mt. Kumo area, however, provided fully-decorated shroud and ritual robes to the level of other better-off areas. It seemed to be the result of influence of deep-rooted Confucianism in Gyungbuk province. This Phenomenon could be found in the folk dress style in other regions as well as the Mt. Kumo area in Gyungbuk province.

  • The purpose of this study is to analyze how the women´s fashion with the design elements(silhouette, material, color, detail and trimming) of androgynous image which has appeared on our specialized fashion magazine from 1986 through 2000. As a result of this study I drew the following conclusion. 1. The bon silhouette led the market in the first stage of mid 1980. The wool and leather with the masculine image, cotton and soft material with unisex image were used to express the androgynous image. The dark and mono tone with the masculine image were used a lot in color. In women´s fashion the minimalism style with simple image was expressed escaping from the decoration, in which the detail and trimming was not found as in men´s wear. 2. It showed that more and more feminine image was accepted in the second stage of early 1990. Women´s wear silhouette with the androgynous image has changed from masculine box silhouette boomed in the first stage to hourglass silhouette and slim silhouette. The wool and leather were used a lot as the materials in the first stage but the usage of the cotton with unisex image and soft texture were getting increased. The main colors were the black and the blue but the usage of the white and the red were on the increase showing the range of the use was extending. In the meantime, the detail and trimming were hardly used like in the first stage. 3. In the third stage of the late 1990, the silhouette has changed to slim style. The wool and leather were mainly used as the materials but the cotton and silk were on the increase showing that the materials of the feminine image were used in the women´s fashion with the androgynous image as well as the materials of masculine image. In color, the black and the white of the masculine image were used increasingly by the effect of the minimalism and the usage of the colors were various for the rising frequency of the trend colors usage.

  • This result of the study on the costume of Osman Turkey are as following. 1. Empire of Osman Turkey(129∼1922) exerted an almost limites impact and influence on Europe and Asia during their regime 600 years. The distant ancestors of the Osman Turks were nomadic peoples, who wandered I tribal groups through the Central Asia. Therefore their costumes were based on nomadic culture. They had trade with West and East were influenced by Hellenism and Byzantium and grew, to a strong Islamic political power polygamy with which influence their clothing along with other culture. 2. Topkapi Saray was one of he principal residences of the Osman sultans and his court. Late 17 century, Topkapi Saray found many of kaftans of Osman Turks Empires of 14∼17 centuries. Otherwise we studied by the minatures of 16∼17 centuries, Since the Topkapi Saray became a museum in 1924, a program of careful restoration has made it possible to some pars of it to the public, after centuries neglection. 3. Osman Turkey Empire had important role in between West and East(silk-road). Economic, commercial, social and political factor of Turkey led to a development in the art of weaving (kema, kadife, catman, seraser, zerbeft, hatayi, kntnu, atlas)parallel to the rise and development of the Osman Turkey Empire itself, one which raised the art to a level attained nowwhere else in the world. Fabrics woven from gold and silver thread occupied a very important place in the court life of the time. This was due as much to their symbolic as to their material value, reflecting as they did the power, glory and magnificence of the Empire. 4. In order to study Eastern or Western history of costume one must study Turkey history of costume in advance. Also there is a great need of comparison to study of western, central and north eastern area history of costume.

  • The dyeing properties of protein fiber with pine needles colorants were studied through an investigation of the effect of dyeing conditions such as dye concentration, dyeing temperatures and time on dye uptakes, effect of mordants, and color change. In addition, the various colorfastness of dyed silk and wool fabrics were evaluated for practical use. The antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. The dye uptake increased as the dyeing concentration increased and this enabled the obtainment of the Langmuir absorption isotherm. The dye uptake increased as the dyeing time and temperature increased. Pine needles colorants showed relatively good affinity to protein fiber and produced a yellow color. Post-mordanting was more effective than the pre-mordanting, and the dye uptake of fabrics improved by mordanting. Except for washing, the colorfastness of dyed fabrics showed a low rating. However, the colorfastness to light and the dry cleaning of fabrics mordanted with N.Cu, and the friction fastness of fabrics mordanted with Cu improved. The guide fabrics showed very good antimicrobial abilities of 99.9%; in addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

  • The theory of household arts and practical acts are two traditional mainstream topics of official South Korean secondary home economics education. The clothing and textile education within the Secondary School Home Economics Textbook (1948) is various and practical. The first year textbook discusses the symbolism and maintenance of uniforms that provides information on the characteristics of cotton. Clothing and textiles are covered in 26 pages out of the 76 page book. The second year textbook includes the theory of color and form, along with the characteristics of flax and silk. Clothing and textile education is covered in 33 pages out of the 97 second year textbook. The third year textbook deals with the characteristics of wool, manufactured fibers, cross weaving, removing stains, clothing arrangements, and equipment; 5 chapters (56 pages out of 137) are spent on clothing and textiles. The fourth year textbook introduces the history of clothing, laundry principles, dyeing, bedclothes, and bed accessories; 4 chapters (63 pages out of 125 pages) are spent on clothing and textiles. The Secondary School Home Economics Textbook (1948) is highly extensive and profound in depth. It is comparable with modern college or specialized high school level clothing and textile education in terms of clothing materials, clothing maintenance, color theories, and dyeing.

  • During the past six years from July 1977 to June 1983, fifteen adult patients of patent ductus arteriosus were surgically treated. The results were as follows: 1. Of the 15 patients, their age range was 17 to 34 years with a mean of 24 years, and sexual predominance was women [9. cf. 6 men]. 2. The most common symptom showed exertional dyspnea, and 10 patients were classed in NYHA class II, the rest were all class III. 3. On physical examination, all patients were auscultated continuous murmur, but concomitantly diastolic murmur was noted apical region in 2 patients. 4. On roentgenogram of chest, normal finding was 3 patients, and the other patients were revealed the evidence of pulmonary congestion. 5. The electrocardiogram was normal in 6 patients, but LVH was seen in 5, and 2 patients were LVH+ LAH. 6. Cardiac catheterization was performed in 12, and mean value of SO2[LPA-RV] was 6.3%, Q/Q 2.09, peak systolic pulmonary arterial pressure 45.3 mmHg, and Rp/Rs 0.365. 7. All operations were carried out by posterolateral thoracotomy. In 6 patients, division and suture of ductus were possible, the other patients were treated by division and ligation with heavy silk or Dacron patch. 8. Postoperative complications were hoarseness, persistent murmur, reoperation for bleeding, and atelectasis. Early and late mortality was 20% [3 patients], and cause of death was mainly aneurysmal rupture of previous operative site.

  • The following is a summary of comparative study on costumes between 『Cheng-Hoe-Jeon-Do』 and 『Chen-De-dang-an』 in Gun-Ryung 41st, 42nd and 43rd yew to find out costume situation actually worn by Emperor Gun-Ryung in Qing dynasty. In Gun-Ryung 41st year, Emperor's costumes showed a sign of royal tour robes. In 42nd year, a phase of mourning robe system came out and a plain side of costumes was shown owing to the mourning. In 43rd year, it showed costume situation worn by Emperor in peaceful year without any particular event. Velvet, material for traveling crown was used in a short time before and after the change of the season besides royal tour and this can be understood as a well-timed and reasonable selection of material. Eventhough robe material, Jik-kyung-Ji-chack-sa(a kind of silk) had been used for summer robes since Gun-Ryung 42nd you. Memorial costumes followed Emperor's court costume system I in 『Cheng-Hoe-Jeon-Do』 and court belt I or II as memorial suit belt was used for the memorial costume of Emperor Gun-Ryung and they properly applied of the costume system in 『Cheng-Hoe-Jeon-Do』 for coats.

  • Since 1966, practical use of active heavy analogs of the hormones has been also worked out as an insecticide and brought the features of it to the light as cocoon producer. On the other hand, it is expected to afford the increase of silk productivity resulted from control of the fifth larval period by delaying normal development. With these regards, some of analogs have been tried to apply practically to the silkworm for an increase of cocoon productivity. One of the synthesized juvenile hormone available is "Manina". And it is presently used for the increase of silk productivity in Korea. For the practical use, it is very essential the varietal differences in the increase of silk productivity by topical application was tested and the obtained results are summarized as follows. 1. It was evident that the fifty larval period was extended by topical application after 48 hrs. of the last ecdysis, ranging from 8 hrs. to one day, as compared to the control. 2. In pupal rates, there is no significance between control and treatments. It proved that there was no toxicity to silkworm by topical application in general, except jam 120. With regards to an increase of cocoon yield in Japanese, it was resulted from 17∼24% of cocoon yield from 10,000 larvae, as compared to that of control. In case of Chinese, the incrasing rates were varied from 15∼26% of cocoon yield, 17.8kg of it with 26% increase for Jam 122 and 16.7kg of it with 25% increase for Jam 118. In case of all hybrids, an increase of the cocoon yield took places from 20% to 31% and the weight of cocoon layer for the Japanese increased by 6 to 14%, those for the Chinese by 4 to 7% and those for the hybrids ranged from 21 to 29% increase. 3. It was recognized that the hybrid vigor rate took places with the hybrids between high responsing parents to juvenile hormones.
