摘要
以硫酸盐马尾松浆为原料,通过对比两种复合绒毛化方法对绒毛浆性能的影响得到,先对原浆纤维进行漂白,漂白接近终点时补加碱进行短时间的浓碱处理为较优的复合绒毛化方法,并通过进一步实验验证了该方法中进行短时间浓碱处理的合理性.结果表明,原浆纤维经复合绒毛化后,纸浆白度为76.66%ISO,提高了52.77%,绒毛浆板耐破指数为0.57kpa·m2/g,下降了48.18%,绒毛浆吸收时间为8.42s,缩短了46.64%,吸收性为8.95g/g,干蓬松度为17.19cm3/g,这两个性能指标分别降低了10.23%,6.63%.
Composite fluffing technology of cellulose fiber in the process of fluff pulp making was researched using pinus massoniana lamb as the raw material. Effects on fluff pulp prop- erties of two composite fluffing technologies were compared. It indicated that bleaching the virgin fiber initially and then treating it with enormous alkali towards the end of bleaching was the more preferable method. It also revealed that when fiber was treated by this method, brightness of it was 76.13% ISO and increased 51.71%, burst index was0. 57 kpa · m2/g and decreased 48.18%, the absorption time was 8.42 s and decreased 46.64% in comparison with virgin fiber. Meanwhile, absorption and dry bulkiness of the fiber decreased 10.23%, 6.63%, respectively. In addition, rationality of the more preferable method for its effects on fiber properties was also researched.
