본 실험은 견직물의 염색시에 많이 사용되는 Acetic Acid, Sulphuric Acid 및 Formic Acid등의 산성화학약제 처리가 생사의 물리적 성질에 미치는 영향을 규명한 것으로서 그 결과는 다음과 같다. 생사의 강력(g/d)은 공시 3개약제 다같이 온도 및 pH 변화에 따른 차이를 인정할 수 없었다, 생사의 신도(%)는 Acetic Acid 및 Sulphuric Acid pH 3에서 Formic Acid pH 4에서 유의차 있게 저하되었다.
This experiment was carried out to determine the effect of acid chemicals namely, sulphuric acid, formic acid and acetic acid on the physical properties of silk especially on tenacity and elongation which are the two most important properties in handling and processing of silk. The following results were observed. It was recognised that there was a significant change in elongation in all the samples tested using the three different chemicals. In the test with acetic acid, the elongation at at pH 3 had a significant change. Change was observed in the test with sulphuric acid at pH 3 and in the case of formic acid test, there was a significant change in the elongation of raw silk at . The above results qualifies earlier findings and studies that recorded that acids like formic acid and other organic acids could have an effect on the physical properties of silk.
