Abstract

In this study, the properties of fibers recycled from MDF wastes as one of the important resources of raw materials for MDF production were investigated. Two different methods including ohmic heating (for 2 and 4 minutes) and hydrothermal method (at 105˚ C for 150 minutes) were utilized for Recycling the MDF wastes and the virgin fibers were used as control sample. The chemical composition of fibers (lignin, cellulose and hemicellulose content), as effective variable on quality of fibers was measured. Also for probing the chemical characteristic of fiber surface, FT-IR test was utilized. In addition, the wettability of fibers was determined using water contact angels on fibers surface. The results showed that Recycling process changed the chemical composition of fibers. Most of the changes were occurred in hemicellulose and extractives content. The results of FT-IR test revealed the existence of more carbonyl groups and furfural and lower amount of hydroxyl groups in recycled fibers compared to virgin fibers due to esterification process. The wettability of fibers was decreased after Recycling process especially in hydrothermal method.
