中文摘要:
      工厂生产实践表明,向抄造体系中添加改善纸张耐高温性能的碱式硫酸镁晶须填料会严重影响直接大红4BS的染色效果,针对这一问题,提出一种在抄造体系中添加高分子助留剂的方法以进行改善。探究了阳离子聚丙烯酰胺(CPAM)、两性聚丙烯酰胺(AmPAM)、阳离子醚化淀粉和TEMPO氧化纤维素纳米纤维(CNF)4种高聚物对直接大红4BS染色效果的影响,其中,添加TEMPO氧化CNF能有效提高纸张a*值。结果表明,当TEMPO氧化CNF的添加量为2%时,直接大红4BS的染色效果提高较明显,且添加TEMPO氧化CNF能有效提高碱式硫酸镁晶须填料的留着率,进而提高纸张的耐高温性能。
Abstract:
      The production practice in factory shows that the addition of basic magnesium sulfate whisker into the papermaking system as a filler to improve the heat resistance of paper will seriously affect the dyeing effect of direct scarlet 4BS. To solve this problem, we proposed a method by adding polymer additives as efficient retention aid into the papermaking system to improve the dyeing effect of direct scarlet 4BS filled with basic magnesium sulfate whisker. The effects of cationic polyacrylamide (CPAM), amphoteric polyacrylamide (AmPAM), cationic etherified starch, and TEMPO oxidized cellulose nanofiber (CNF) on the dyeing effect of direct scarlet 4BS were evaluated. It was found that the addition of TEMPO oxidized CNF can effectively improve the dyeing effect of direct scarlet 4BS. The results also showed that when the addition of TEMPO oxidized CNF was 2%, the dyeing effect of direct scarlet 4BS could be significantly increased. Furthermore, the addition of TEMPO oxidized CNF could effectively increase the retention rate of basic magnesium sulfate whiskers, thereby improve the heat stability of paper substrate at high temperature.
