摘　　要：研究了黄原胶、普鲁兰多糖、葡聚糖、α-环糊精4种微生物多糖的添加方式和用量对高透滤棒成形纸强度、透气度等性能的影响。结果表明,普鲁兰多糖对高透滤棒成形纸的增强效果明显优于其他3种多糖,且浸渍处理比浆内添加更有利于强度性能的提升。利用不同打浆度的针叶木浆、针叶木浆与丝光浆混合浆、针叶木浆与黏胶纤维混合浆制备了具有不同透气度的高透成形纸,经普鲁兰多糖浸渍后,高透成形纸强度性能均随着上胶量增加而增加,透气度随上胶量增加无明显变化。与未浸渍纸张相比,浸渍普鲁兰多糖后,上胶量约3.0 g/m^(2),打浆度15°SR、18°SR、21°SR的针叶木浆所抄纸张抗张强度分别增加了69.9%、69.2%和67.5%,18°SR针木叶浆与丝光浆配抄纸张抗张强度增加了96.5%,与黏胶纤维配抄纸张抗张强度增加了126.0%。The effects of the addition method and dosage of xanthan gum,pullulan,dextran andα-cyclodextrin on the strength and air permeability of high porous filter plug wrapping paper were studied.The results showed that the strengthening effect of pullulan on high porous filter plug wrapping paper was significantly better than that of the other three kinds of polysaccharides,and impregnation was more conducive to the improvement of strength performance than adding into pulp for increasing paper strength.High porous filter plug wrapping paper with different air permeability was prepared from softwood pulp with different beating degree,mixed pulp of softwood pulp and mercerized pulp,and mixed pulp of softwood pulp and viscose fiber,and then impregnated with pullulan.The results showed that the strength increased while the air permeability did not change significantly with the increasing of the gluing amount of pullulan.Compared with non-impregnated paper,when the gluing amount of pullulan was about 3 g/m^(2),the tensile strength of paper prepared by softwood pulp with beating degree of 15°SR,18°SR,21°SR was increased by 69.9%,69.2% and 67.5%,respectively.The tensile strength of paper prepared by mixed 18°SR softwood pulp and mercerized pulp,viscose fiber was increased by 96.5%and 126.0%,respectively.
