This study was carried out investigate the characteristics of Habutae and Chiffon woven with silk and polyester(S/P) compound yarn. The S/P compound yarn could be produced by the automatic reeling machine with attachment of air jetting device, polyester yarn guider and tension control apparatus. The surface structure, tensile property and dyeing fastness of S/P compound fabric were examined for the fabric properties. Electron microscopy revealed that most part of S/P compound yarn was well interlaced and some silk part of compound yarn were hidden by polyester on an examination of surface of chiffon fabric. By the one bath and two step dyeing of disperse and acidic dyes, the colour fastness of S/P compound fabrics were 4 grade above. The tenacity and initial modulus of the finished S/P compound fabric were lower than those of grey and degummed fabrics, but reversed in elongation.

In this study several kinds of spun silk yarn-synthetic filament compounded yarn was manufactured, and several fabrics woven from above mentioned silk compound yarn for evaluation of serviceability as clothing materials. The following results were obtained: 1. Degumming agents are in the order of sodium silicate, sodium hydroxide, sodium carbornate, soap and water. 2. When the concentration of sodium hydroxide is exceeded 3%, degradation of floss silk property is resulted because of excessive dissolving out of silk protein. 3. Degumming effect is much improved by concentration of degumming agent and less by its treating time. 4. Simultaneous application of more the 2 kinds of degumming agent is desirable for improvement of floss silk. 5. Application of natural organic acid brings very good results in keeping original scooping and color of the silk. 6. Load and elongation it increased by compound with synthetic filament yarn. 7. Even the evenness of compound yarn is largely dependent on the quality of floss silk and extent of degumming, the C.V.% of silk compound yarn in the experiment was 8-12%. 8. Single bath dyeing technique was impossible for their cloth, and dyeing was performed in 2 bath system separately for silk and synthetic fiber. 9. Shrinkage ratio due to the dyeing of fabric was 23% in case of polyester and spun silk fabric. 10. The final woven cloth can be applicable to (a) Blouse in care of thin cloth (compound silk fabric) (b) Korean costume for women in case of thick cloth. (compound hand spun silk fabric)

Interlace textured yarn was developed in order to increase weaving process efficiency. Today, interlace texturing is very useful method of manufacturing the high added value compound yarns for new synthetic fabrics. In this research, new silky type high added value compound yarns were. manufactured by interlace texturing technology and tested their properties. The object of this research is to investigate the relationship between interlace textured yarn properties and processing parameters that is air pressure, yarn tension and take-up speed. The original filament yarns used were TTD(Thick & Thin Semi-Dull) 110d/72f and SCD(Semi-Dull Cation Dyeable) 75d/36f. 27 specimens were manufactured and tested for their physical properties-nip density, tensile properties, multi-step shrinkage test and surface structure by SEM. The air pressure was main process condition to change properties of interlace textured yarns. And interlace textured process had influence on weaving preparation process, weaving, knitting and so on. It has some influence on shrinkage properties of dyeing and finishing processes.

This study was carried out to investigate the physical characteristics of stocking knitted with silk/nylon(S/N) compound yarn. In SEM observation, it was found that most part of S/N stocking was well interlaced between silk and nylon yarn. There was no difference between S/N stocking and nylon stocking in shrinkage at warm water and compressive resilience. The suction height and absorbability of S/N stocking was 4~8 times and 3 times higher than that of nylon stocking, respectively. According to the wearing test survey, most of wearers answered that the warmth, the hand and the feeling cool of S/N stocking were better than those of nylon stocking but reversed in elasticity, and they gave sprit opinion on durability responding good impression in total feeling of S/N stocking.

Kayagum is a traditional musical instrument in Korea. Kayagum strings are usually made of raw silk. It needs good vibration and durability. This study was carried out to increase durability of the strings by chemical treatment and manufacture of silk/polyester and silk/wild silk compound yarn. In this study, we used MKW-810(water solube acrylic adhesive)and polyvinyl alcohol as a adhesive. Before the twisting, the raw silk wet on the string manufacture process. The adhesive reagent were added in this process. And compound yarn were prepated by domestic silk, polyester and wild silk(antheraea pernyi) for make of Kayagum strings, respectively. The result are as follows. 1. Tenacity and elongation of the strings are almost same between none and chemical treatment. However number of extension cycling to breaks of the strings was largely increased by chemical treatment. Number of extension cycling to breaks of the strings is very important and useful item to check durability of the strings. The stiffness of the strings were almost same between none and adhesive treatment 2. Tenacity of the silk/polyester strings is largely decreased by increasing of polyester portion, but elongation of the silk/polyester strings increased. However tenacity of the silk/polyester(mono filament) strings are higher than that of silk strings. 3. Tenacity of the domestic silk/wild silk strings is largely decreased by increasing of wild silk portion, but elongation of the domestic silk/wild silk strings is almost same among silk and domestic silk/wild silk strings.

The purpose of this study is to review the literatures and the wall paintings of the ancient tombs of Koguryo in an effort to try to understand the characteristics of the culture of dyeing in Koguryo. The research findings follow: 1. The colors that were in vogue in Koguryo are five cardinal colors (red, blue, white, black, and yellow) and compound colors, like purple and green. Those colors were used in some or all parts of the clothing and even on some parts of the body. 2. Some clothing of Koguryo as shown in the wall paintings were made with a single and solid color by dip dyeing method. But the majority of the clothing had a variety of patterns. Among the patterns, the geometrical dot pattern took the majority. 3. The dyeing techniques used in Koguryo were printing, yarn dyeing, embroidery, wax resist dyeing, drawing and painting. The development of yarn dyeing method, weaving with silk-threads dyed in various colors, enabled to produce Geum fabrics, which were used for the upper classes' clothing. 4. The esthetic features represented in the colors of Koguryo include the beauty of contrast coloring, preference for red, preference for geometrical patterns, and the harmony of yin and yang.

The purpose of this study was to develop the High Functional Covering machine and the Compound Twister to produce the high value added textile goods and to meet the consumer's needs. For the study, 8 yarns and 12 fabrics were made with two developed machines and the tensile characteristics of the samples were tested and analysed. The result indicated that the sample fabrics kept their elongation regardless of buffering process. Elongation of the sample yarns was higher than those of yarns made with a traditional covering method. Elastic recovery of the sample fabrics was more effected by the recovery rate than by the number of extension and the characteristics of the sample yarns and fabrics were comparable to the yarns and fabrics made with a traditional covering method in terms of the position of Spandex yarns in their yarn structure and buffering effect.
