Modification and fiber preparation of soda lignin

  • 摘要: 为改善碱木质素的熔融性能,实现熔融纺丝法制备碱木质素基纤维,以制浆造纸黑液粉末中提取的碱木质素为原料,与不同质量比的聚乙二醇-400(PEG-400)混合加热,再倒入水中搅拌不同时间后过滤干燥,测定改性处理后碱木质素的热稳定性、黏度及熔融纺丝性能等特征。结果表明:1)在相同搅拌时间时,不同质量比的PEG-400改性处理对灰分含量影响不大,木质素含量随质量比的增加而变少或不变;在相同质量比时,搅拌时间越长,灰分含量越少,木质素含量越多。2)经PEG-400改性处理的碱木质素的热分解温度增加,热稳定性能提高;但随着质量比或搅拌时间的增加,其热分解温度均减少,热稳定性能降低。3)质量比为1:1和1:2时PEG-400改性处理的碱木质素均表现出较差的熔融性能,而质量比为1:3时PEG-400改性处理的碱木质素呈现较好的熔融性能,尤其是搅拌时间为2h的碱木质素则表现出较稳定的熔融性能,并且能够在228℃温度下熔融纺丝制备得到直径约为(30±4.8)μm的碱木质素基纤维。
