The Effect on Wangol Quality by Procesoing Condition

관초의 가공조건이 품질에 미치는 영향

From old times wangol has been processed on a small scale for domestic use in rural society. But, nowadays many forms of wangol products are appearing and becoming useful in various ways. The demand for these wangol products is increasing in big cities and foreign countries; and owing to it's popularity abroad, wangol Processing has become one of Korea's important export industries. Now in order to study on wangol quality, we made experiments on scouring, bleaching, and dyeing. Results of the study are follows; The storing of raw material decreased the strength, and alkali and heat treatment could not be recomended. In case of bleaching the fresh wangol was mere effectively bleached than the processed wangol, and sulfur dioxide was more effective than bleaching powder for the bleaching of wangol. Direct dyeing and reactive dyeing were useful for the dyeing of wangol. For maintaining the quality of raw materials reactive dyeing was more effective, but direct dyeing was more economical.
