전통한지를 활용한 패션 악세서리 상품개발 (제1보) -실리콘 수지로 처리된 한지의 물성변화- A Study on the Fashion Accessary Product Development by Use of Korean Traditional Hanji (Part I) -Physical Properties of the Korean Traditional Paper(Hanji) Treated with Silcone resin-원문보기
한지를 의류용으로 사용하기 위한 시도들이 있었지만, 습윤상태에서 물리적 성질이 크게 감소한다는 문제점 때문에 많은 한계를 가지고 있었다. 따라서 한지의 습윤상태에서의 물리적 성질을 향상시키기 위해 내수성을 부여하고자, 실리콘 수지를 이용하여 한지에 발수가공을 행하였다. 패드-드라이-큐어 방법을 사용하여 처리하였고, 가공의 최적조건을 알아보기 위해 수지의 농도와 촉매의 농도, 큐어링 시간과 온도를 변화시켜 실험하였다. 한지의 발수도, 강연도, 방추도를 측정하였고, 습윤과 건조상태에서의 인장강도, 인열저항 마찰저항을 비교하였다. 그 결과 한지의 발수가공을 위한 최적처리조건은 실리콘 수지농도 40g/l, 촉매농도는 수지농도의 1/2인 20g/l, 큐어링 온도 160$^{circ}C$, 큐어링 시간 120초였다. 가공 후에도 한지의 유연성은 크게 저하되지 않았으며, 방추도는 약간 증가하였다. 가공 후, 건조상태에서의 인장강도, 인열저항은 큰 변화가 없었으나 내마모도는 증가하였고, 습윤상태에서의 인장강도, 인열저항, 내마모도 모두 증가하였다.

There are attempts to utilize Hanji for apparel material, but, the reason that the strength and durability of Hanji decrease to a great extent in the wet condition, restricts the usability of Hanji. In order to improve the resistance against water, Hanji was treated with silicone type water repellent agents. The treatment was carried out by conventional pad-dry-cure method. The optimum treatment condition was obtained by varying the concentration of repellent agent, curing temperature and time. Water repellency was tested by spray rating method. Wet and dry tensile strength, tearing resistance and abrasion resistance were examined after the treatment. Flexural stiffness and wrinkle recovery angles of hanji were also measured. In result, the optimum condition of treatment was at resin concentration of 40g/l, catalyst concentration of 20g/l(half of resin concentration), curing temperature of 160$^{circ}C$, curing time of 120 sec. Flexural stiffness of Hanji was hardly increased and wrinkle recovery angle of Hanji was improved a little by resin treatment. After the treatment, in dry condition, tensile strength and tearing resistance were little changed but abrasion resistance was improved. In wet condition, tensile strength, tearing strength and abrasion resistance were improved.

가설 설정
1. The optimum condition of treatment was at resin concentration of 40g/l? catalyst concentration of 20g/l (half of resin concentration), curing temperature of 160°C, curing time of 120sec.
3. Flexural stiffness of Hanji was hardly increased by resin treatment.
이론/모형
The treatments of silicone resin were carried out by the conventional pad-dry-cure method. The sam ples were cut into 30x30crn2 and immersed in the bath containing resin and catalyst for 30minutes.
Water Repellency was evaluated by spray test method based on KS K 0590.
성능/효과
2. The higher add-on of silicone resin on Hanji, the better water repellency was.
4. Wrinkle Recovery Angle of Hanji was improved a little after the resin treatment.
5. In dry condition, flexural stiffness, tensile strength and abrasion resistance were decreased at resin con centration of 10g/l and after that, increased and lev eled off. Tearing resistance was little affected by resin concentration in dry condition.
