Abstract

The skin and fleshy substance on the net fiber of sponge-gourd fruit pressed mechanically was removed with 0.2% NaOH solution in $3{\sim}5$ hours. The treatment of 0.2% NaOH with 0.02% Monopol(non-ionogenic polyoxethylen derivative) as surfactnat and with 0.1% $Ca(OCl)_2$ as bleaching agent enhanced the effect to remove the fleshy substance and improve the quality of net fiber. Also, the wet hardness and tensile strength of net fiber were controlled by the crosslinkage of the fiber with glu tardialdehyde, glyoxal, and formalin, respectively. The net fiber was stable on the acid and alkaline solutions. Also the range of temperature to degradate the fiber was $338{\sim}385^{\circ}C$. These values indicated a fair stability. The improved net fiber can be used for raw material of bath, dish washing, oil and gas filter, and many kinds of decorations.

일반 농가에서 수세미 사과락의 표피 및 그물섬유중 육질 제거를 위하여 개천수에 침지하여 20여일 소요되는데 비하여, 사과락을 압착한 후 0.2% NaOH로 처리한 결과 $3{\sim}5$시간내에 처리가 가능하였다. 0.2% 알카리 용액과 계면활성제인 0.02% Monopol과 표백제인 0.1% $Ca(OCl)_2$를 처리하여 섬유소의 품질을 보호하면서 육질제거효과를 기할 수 있었다. 또한, 사용 목적에 따라 습경성과 인장강도와 같은 물리성을 formaldehyde, glutardialdehyde, glyoxal과 같은 가교제를 사용하여 조절할 수 있는 가능성을 나타냈다. 또한 산알카리 및 열적 안정도가 양호하여 목욕용 기구, 주방용 세척기구, 오일이나 까스 여과기, 기타 각종 장식용 제조 원료로 사용가능하다는 결론을 얻었다. NaOH 용액의 농도 저하와 KOH로 대치할 때 생성되는 스럿지를 K질 비료로 활용하는 방안 등이 연구중이다.
