Lignin Degradation of Kapok Fiber (Ceiba pentandra, L) with Different Times of Pulping
Journal of Applied Agricultural Science and Technology, 2023 Lignin reduced the adhesion between the polymeric matrix and natural reinforcement in composite materials by its hydrophobic characteristic. Removal of lignin can be a solution to improve fiber function in composite use. This study aimed to determine the
