본연구는 백반이 sericin 정착하는 작용을 구명하기 위해서 시행된 것이며 이미 유혁기술에서 사용하여 오던 실예를 생사에 적용해보려는 것이었다. 타인의 보고는 Cr-명반이나 tannin, formalin 또는 vinyl acetate로 sericin 정착한 사실이 있기는 하나 이들은 섬유의 흡습성을 도외시한 것이어서 본보는 섬유의 흡습성을 보존하면서 sericin 정착을 하는 방식을 취하기로 했다. 한편 sericin 정착기구를 상세히 알기위해 섬유의 침간 mechanism과 정착 mechanism도 고찰하여 보았다. 본실험에서 얻어진 결과는 다음과 같다. 1. 백반을 sericin 정착에 이용할 때는 타인의 보고에서와 같이 고온처리는 금물이며 고온처리는 섬유를 경화시켰다. 2. 백반을 저온처리하는 대신 3 시간 이상 처리함이 바람직하였고 이때 백반만으로도 sericin 정착과 더불어 방수효과를 보였다. 3. 1% 백반농도이면 sericin 정착이 가능하였다. 4. sericin 정착만 고려할때는 0.5% NaOH 10분간 처리후 1% 백반용액 3시간처리방식이 가장 좋았다. 5. 그러나 sericin 정착과 흡습성을 고려할때는 상기 방식의 역방법이 가장 좋았다. 6. sericin 정착검정은 습윤시료의 건조곡선도시로 더욱 선명하게 다루었다. 7. 연감률은 백반 -NaOH 처리의 경우 4.3%였는데 이러한 정도이면 실용 선습에 능히 sericin 유실을 막을 것으로 본다. 8. 흡습성도 백반-NaOH 처리방식에서 미처리손과 동일한 흡습성을 유지했다. 9. 처리직후와 처리 3개월후의 강력경도에 변화가 없었다. 10. 결론적으로 본처리는 무연무색처리로서 유색처리(탄닌, Cr-명반)방법과 취기처리(formalin, vinyl acetate 처리)보다 개선된 방식이었다.

This has been carried out how the sericin insoluble fixations of raw silk should be with potassium alum. This is learned from the leather tanning technique which the process works with collagen, a kind of proteins. Former reports had shown such works, however, they did not consider the moisture absorbability after their process reports by using chromium alum, formalin or vinyl acetate grafting. This report, however, paid attention to protect such absorbability as well as sericin fixation, so far it may be useful for plactical use of silk. In order to clear how the sericin is fixed with such chemicals, fundermental mechanism of weding process and chemical reaction against proteins were also discussed. The obtained results of the report are as followings. 1. Alum should not be treated for raw silk with high temperature bath like other reports because such treat induces raw silk to be stiffly after the treat. 2. It is recommended that raw silk should be treated with alum solution at room temperature for more than three hours. Even in this case, the use of only alum with raw silk could to fix sericin some how, but it increased the water proofness of the silk. 3. 1% of alum solution was found to be able to fix the sericin of raw silk. 4. In case we consider only sericin fixations, a combination treat of 1% alum for three hours and 0.5% NaOH for ten minutes method showed the best result. 5. In case we consider sericin insoluble fixation and moisture absorbility, the reversive combination of the above process was found to be the best results. 6. Sericin fixing evidence was shown with drying feature curves of wed each treated silk where we could to analyze how the chemical nature is changed after each treat. 7. Deguming ratio may be obtained up to 4.3% after the alum combination treat with regular raw silk. Such ratio was considered to be good enough for the purpose when the textile is washed with warm soap water. 8. Moisture absorbability of the combination treat of alum and NaOH was found to be good enough as well as non treated silk. 9. The tenacity and elongation of the treated silk did not change even after three month. 10. Above all, this method is considered to be better process than other coloured fixing (tannin method. Cr-alum method) or smell fixing (formalin method. vinyl acetate method).
