| 摘 要： | 通过选择性的脱除纤维细胞壁中的半纤维素和木素,研究半纤维素和木素含量对再生植物纤维品质衰变的影响.研究结果表明:随着半纤维素含量的减少,再生植物纤维的保水值降低,结晶度增加.当半纤维素含量从27.62%降至9.09%时,保水值下降了41%,纤维素结晶度从1.011增加到1.514.半纤维素含量与再生植物纤维成纸性能的变化有明显的线性相关性.较高含量的半纤维素可以缓解回用过程中再生植物纤维成纸性能的损失.同时发现木素对再生植物纤维性能的影响很小.木素含量与纤维的保水值、结晶度与成纸性能的变化没有明显的线性相关性.

| Abstract: | The influences of hemicelluloses and lignin content on the quality decay of recycled plant fiber were investigated through selective removal of the hemicellulose and lignin in the fiber cell wall. The results indicated that with the decrease of hemicelluloses content the water re-tention value decreases and the crystalline degree of cellulose increases. With the hemicelluloses content decreasing from 27.62% to 9.09%, water retention value decreases by 41% and the crystalline degree of cellulose increases fr... |
