A Study on Pulping of Paper Mulberry Bast Fiber Using Deep Eutectic Solvent Based on Resorcinol-Choline Chloride; Resorcinol-choline chloride 기반 공융용매를 이용한 닥나무 인피섬유의 펄프화 연구

초록

This study evaluated whether the pulping of paper mulberry bast fibers is possible using deep eutectic solvent based on resorcinol-choline chlorde (RC DES). In particular, the effect of the mixing ratio of water in the RC DES on the pulping efficiency was investigated. As the results, it was found that the screen yield of pulp fiber increased with increasing the mixing ratio of water. In constrast, the reject, which was not fully cooked, showd a decreased pattern. Consequently, it was found that the higher the mixing ratio of water, the higher pulping efficiency. These results are consistent with an increasing pattern in conductivity as well as with a decreasing tendency in viscosity, indicating the fluidity of DES-RC cooking liquor enhanced by the increases of the mixing ratio of water. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry.
