以漂白针叶木硫酸盐化学浆为原料,分别采用9%NaOH,6%NaOH+3%H2O2,1%H2SO4,9%H2O2等化学法和木聚糖酶、漆酶及混合酶等生物法进行处理,探讨不同处理方式对漂白针叶木纸浆改性制备黏胶纤维用溶解浆的影响。试验结果表明:采用9%NaOH,1%H2SO4能有效提高α-纤维素含量和纤维素反应性能,而木聚糖酶或漆酶的处理效果不明显。 The bleached softwood kraft pulp was used as the raw material, and was chemically treated with 9% NaOH, 6% NaOH + 3% H2O2, 1% H2SO4, 9% H2O2 and other biological methods such as xylanase, laccase and mixed enzyme The effects of different treatment methods on the dissolving pulp of bleached softwood pulp modified viscose fiber were discussed. The results showed that using 9% NaOH and 1% H2SO4 could effectively increase the content of α-cellulose and the reaction of cellulose, while the treatment effect of xylanase or laccase was not obvious.
