繭層 Sericin에 對한 몇 가지 化學藥劑 處理의 效果
李仁銓,李東秀,千承祿 COLLEGE OF AGRICULTURE KYUNGPOOK NATIONAL UNIVERSI 1985 慶北大農學誌 Vol.3 No.-
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 (Na_(2)O_(2)), the second was sodium carbonate (Na_(2)CO_(3)), the third was sodium sulfite (Na_(2)SO_(3)), the weakest was ammonia water (NH_(4) OH) 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 (C_(14)H_(10)O_(9)), the second was stannic acid (Sn(OH)_(4)), the third was formic acid (HCOOH) and the weakest was methyl alcohol (CH_(3)OH) 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.
