Silk fabrics were degummed and dyed in one bath under the condition of high temperature and high pressure and the results obtained were summerized as follows. 1. The degumming ratio is nearly the same as that of two bath method under the normal condition and the optimal condition is for 30 minutes at $120^{\circ}C$. 2. The dyeing absorption ratio is a little lower than that of two bath method. 3. The tensile strength and elongation are hardly shown the difference between two methods. 4. The fastness of the dyed fabric of one bath method is a little better than that of two bath method. (light, washing, rubbing) 5. The stiffness of the silk fabric treated by one bath method is a little harshier compare to that of two bath method.

Antheraea pernyi silkworm is a well known wild silkworm to produce a valuable silk fiber. A. pernyi silkworm was reared in Korean oak field and examined the cocoon characteristics, such as cocoon weight, cocoon shell weight, and percentage of cocoon shell weight. Degumming loss was also measured after alkali degumming process. A. pernyi silkworm spins tawny color cocoon in oval shape. Cocoon shell weight of A. pernyi silkworm, 0.78 g, was heavier than that of B. mori silkworm, 0.51 to 0.63 g. Cocoon shell percentage of A. pernyi silkworm, 32.8%, was higher than that of B. mori silkworm, 23.4 to 25.2%. Degumming loss percentage of A. pernyi silkworm, 17.1%, was lower than that of B. mori silkworm, 25.0%. SEM showed that the surface of the cocoon filament was coarse and oriented with longitudinal direction.

생사에 G.A.(glutaraldehyde)와 formalin을 혼합처리하는 방법으로 세리신정착을 실시한 다음 세리신 정착효과, 정착에 따른 백도의 변화, 물성 변화 등을 검토한 결과를 요약하면 다음과 같다. 1. G.A. 농도에 관계 없이 formalin 1% 용액 이상으로 정착하면 미정착사의 96%까지 백도가 향상된다. 2. Formalin G.A의 혼합처리에 의해 정련에 의한 백도 감소를 방지할 수 있었다. 3. Formalin 0.5% 용액 혼합처리로 완전한 세리신 정착을 얻을 수 있었다. 4. 세리신정착처리는 미정착사에 비해 강·신도의 증가를 가져왔다. 5. 정착사와 미정착사의 표면구조는 큰 차이가 없었다.

Natural silk is formed by two proteins ; the crystalline fibroin (inside the silk thread) and amorphous sericin (as a tube outside the thread). The degumming process is used th eliminate the external sericin prior to dyeing ： generally it makes use of soaps at pH 10. (omitted)

Silk nonwoven fabrics are prepared by needle punching and thermal bonding with silk waste. To enhance the carding efficiency, the degumming rate was controlled with sodium hydrogen sulfite solution. The amount of the remained sericin was 3%(S-3), and 6%(S-6). Mixing wool and LMP(Low melting polyester) with the silk, to improve carding efficiency, was also effective. Following items were tested with prepared silk nonwovon fabrics : weight, thickness, compression, tensile strength, heat insulation, water absorption, and deodorization. The results show that the silk nonwoven fabrics could be used for apparels and new biomaterials.

Eco-friendly and health-functional clothing is now becoming the target of the worldwide hot trends. The purpose of this study is to develop an eco-friendly textiles to decrease environmental pollution and to be harmless for human health by investigating how the natural chorangak liquid treatment affects the changes of mechanical properties and the hand of silk fabrics according to different treatment conditions. Treatment was varied with various temperatures ($85^{\circ}C$, $90^{\circ}C$, $95^{\circ}C$) for 90 seconds after degumming. The results were as follows: 1) The natural chorangak liquid is the most effective at the ratio of glacial acid 200ml with eggshell 20g minimizing the time limit and sludge reduction. Its treatment of silk fabrics is optimized at $90^{\circ}C$ for 90 seconds with 25% conc. after degumming when considering tenacity and elongation. 2) After the treatment, tenacity and elongation of specimen are increased compared with those of degummed silk fabrics. 3) After analyzing the effect of the treatment on the characteristic values of basic mechanical properties of silk fabrics, mechanical properties (tensile, bending, shearing, compression, surface) are overall improved. The properties of thickness and weight are increased as well. 4) Based on the clear analysis on effects of the treatment on the mechanical properties and the hand of silk fabrics, the level of THV was enhanced from good to excellent. Therefore, chorangak liquid can be utilized satisfactorily as a new finishing agent for developing eco-friendly textiles.

The effect of cultivation season on the cocoon filament quality of authorized silkworm variety, GoldenSilk was examined with cocoon filament character, reeling character, and fiber character during 3 years. In cocoon filament character, filament length of spring and autumn cocoon was 979 and 879 m, respectively. Cocoon filament weight of spring and autumn cocoon was 33.1 and 26.5 cg, which is lower than that of general bivoltine strain, BaeGokJam. Raw silk percentage of spring and autumn cocoon was 15.65 and 13.77%, respectively. In reeling character, reelability showed similar trend regardless of cultivation season and strain. However, the length and weight of non-broken filament of spring season were slightly higher than those of autumn cocoon. Cultivation season did not affect on the fiber characteristics such as clearness and neatness, lousiness, and degumming loss. In cocoon character, filament length, size, and weight, spring cocoon filament showed higher value than autumn cocoon, but lower than authorized general silkworm varieties. In reeling characteristics, non-broken length and weight showed the similar trends with the cocoon filament character. However, the reelability of GoldenSilk cocoon was not affected by cultivation season. The reelability of GoldenSilk cocoon was also similar with that of authorized general one. Fiber character including clearness and neatness, lousiness, and degumming loss was also similar regardless of the rearing season and different strain.
