【摘要】 本研究以二醋酸纤维丝束为主要原料，与植物纤维配抄烟用滤嘴棒填充用醋酸纤维纸（简称CAP），以CAP的抗张强度、透气度、柔软度等为考察指标，研究了醋酸纤维长度、配抄纸浆的种类、打浆度及添加纳米纤维素等对CAP性能的影响，用200 mm试验纸机进行了连续抄纸试验，并进一步加工成细支复合纸嘴棒。结果表明，优选的主要工艺条件：丝束纤维平均长度2.5～3.5 mm，配抄纸浆种类为针叶木浆，配抄比例30%，打浆度55～70°SR，添加2%的ZM24-2纳米纤维素，CAP的抗张强度提高了278%。烟气过滤实验表明，相较于纯醋酸纤维棒，焦油含量降低了9.4%，且透气度及柔软度满足滤棒成型机上机成棒要求。更多还原

【Abstract】 This study utilised diacetate fibre bundles as the primary raw material, blended with plant fibres to produce cellulose acetate paper(CAP) for tobacco filter filling. Evaluating CAP’s tensile strength, air permeability, and flexibility as key indicators, Continuous papermaking trials were conducted on a 200 mm test paper machine, with further processing into fine composite filter. Results indicated the optimal process con-ditions: average fibre bundle length of 2. 5～3. 5 mm, softwood pulp as the blending pulp type at 30% proportion, refining degree of 55～70 °SR, and addition of 2% ZM24-2 nanocellulose. This configuration increased CAP tensile strength by 278%. Cigarette filtration tests showed that the tar content was reduced by 9. 4% compared to pure acetate filter, whilst air permeability and softness met requirements for filter formation on the filter moulding machine.更多还原
