摘　　要：研究针叶木浆纤维与不同比例玻璃纤维配抄成纸的性质变化,实验中针叶木浆打浆度分别为23、33、39、47、55°SR。研究结果表明:针叶木浆和玻璃纤维配抄对手抄片的留着率影响明显,玻璃纤维配加比例越大,留着率越小;随着玻璃纤维的增加,手抄片厚度变大,紧度变小;同一配抄比例,针叶木浆打浆度越高,手抄片定量和厚度越小,紧度越大;玻璃纤维配加比例从50%提高到80%,抗张指数减小近80%,同一配比下,针叶木浆打浆度为55°SR时手抄片的抗张指数最高;玻璃纤维含量越大,手抄片撕裂指数越小,透气度越大,针叶木浆打浆度为39°SR时对应的手抄片透气度最大;针叶木浆中配加玻璃纤维能够明显改变纸张的导热系数,纯针叶木浆手抄片导热系数为0.0475W·(m·K)-1,随着玻璃纤维配加比例的增大,导热系数不断减小。Softwood pulp fiber and glass fiber were chosen as raw materials for papermaking. Results showed that the thickness of handsheets became large, the tightness became small, tensile strength decreased and the air permeability became large. When a certain amount of glass fiber was added, all indicators have an opposite change with the freeness of softwood pulp increased, the thermal conductivity of pure softwood pulp handsheets was 0.0475 W-（m·K）^-1, and the larger the amount added, the smaller the thermal conductivity.
