본(本) 실험(實驗)은 견층(繭層) seicin에 대(對)한 몇가지 화학약제(化學藥劑) 처리(處理)의 온도별(溫度別), 농도별(濃度別) seicin 용해성(溶解性)에 미치는 영향(影響)을 조사(調査)하였던 바 다음과 같은 결과(結果)를 얻었다. 1. 공시(供試) 해서촉진제중(解舒促進劑中) 견층(繭層) seicin의 용해촉진력(溶解促進力)이 가장 큰 약제(藥劑)는 sodium peroxide()였으며, sodium carbonate(), sodium sulfite() ammonia water()의 순(順)으로 용해촉진력(溶解促進力)이 작았다. 2. 공시(供試) 해서억제제중(解舒抑制劑中) 견층(繭層) sericin의 용해억제력(溶解抑制力)이 가장 큰 약제(藥劑)는 tannic acid()였으며, stannic acid(), formic acid(HCOOH)< methyl alcohol()의 순(順)으로 용해억제력(溶解抑制力)이 작았다. 3. 공시(供試) 해서억제제중(解舒抑制劑中)에서 formic acid와 stannic acid는 의 고온(苦蘊)에서는 견층(繭層) sericin의 용해(溶解)를 크게 촉진(促進)하였다. 4. 공시(供試) 해서억제제중(解舒抑制劑中) methyl alcohol의 경우(境遇)는 저농도(低濃度)에서는 용해억제력(溶解抑制力)이 전혀 없었다.
The purpose of this study was to find out effects of several chemicals treatment for cocoon sericin. and there was several results of use to control the solubility of cocoon sericin in water. The results obtained was summarized as follows ; The chemicals which showed the strongest accelerating power on the solubility of cocoon sericin in water was sodium peroxide (), the second was sodium carbonate (), the third was sodium sulfite (), the weakest was ammonia water () in order among noticed silk-reeling accelerators. The chemicals which showed the inhibiting power on the solubility of cocoon sericin in water was tannic acid (), the second was stannic acid (), the third was formic acid (HCOOH) and the weakest was methyl alcohol () in order among noticed silk-reeling inhibitors. Particulary stannic acid and formic acid showed accelerating power on the solubility of cocoon sericin at high temperature over 100 degrees of celsius thermometer in water Methyl alcohol did not show the inhibiting power on the solubility of cocoon sericin in low concentration.
