Experimental results showed that the CPF improved the retention of precipitated calcium carbonate filler significantly. With 0.9% CPF (based on oven-dry pulp), the retention of PCC increased from 57.53% to 72.21%. The physical properties of paper were also slightly improved. The tensile strength and burst strength of the paper with CPF were higher than those with CPAM.

结果表明，用作麦草浆湿部添加剂的制得的阳离子纸浆纤维能显著提高沉淀碳酸钙填料的留着率，添加0.9%的CPF即可使PCC的留着率从57.53%提高到72.21%，同时能够对纸张的物理性能有所改善，添加CPF的麦草浆成纸的抗张强度和耐破强度要明显高于添加CPAM的，而不低于添加未改性加拿大漂白针叶木浆纤维的。
