Abstract

Dochim is a kind of finishing process in traditional handmade-hanji for increasing the structural and surface properties of sheet such as density, smoothness, gloss and tensile strength. The dochim process is similar to manual calendering process in the western papermaking. Through this process, the structure of fiber mat becomes compact, and the surface of paper becomes smooth without causing fuzz. Dochim develops the strength and beautiful sheen to the paper. However, dochim is an extra hardworking step for quality improvement of hanji and requires an extreme care, physical efforts, and intuition. For surface finishing treatment of sheet, the dochim in the traditional papermaking is similar to the calendering process using modern papermaking equipment.

In this study, the effect of calendering on structural and surface properties of traditional handmade-hanji was investigated by using a pilot supercalender machine. Some process variables of supercalendering were controlled at pressure, temperature and passing times. After calendering, the successful results in density, PPS roughness, smoothness, gloss and opacity of handmade hanji were obtained from the calendering pressure at 1.5 kgf/cm2, the temperature at 60℃, and calender passing times.
