摘　　要：通过正交实验得到提高纸页湿强度的最佳等离子体处理条件:处理时间5min,处理压力400Pa,处理功率30W。在此条件下处理马尾松硫酸盐浆,纸页湿抗张指数提高约35.8%,抗张指数与零距抗张指数变化不大。利用XRD、XPS、AFM和SEM等技术分析和探讨低温等离子体处理提高纸页湿强度的机理,等离子体处理不会对纤维主体结晶结构造成破坏,由于其氧化作用,纤维表面可形成新的极性基团,部分抽提物、污染物或木素被脱除,纸页的湿强度提高。The optimum treatment parameters were got via orthogonal experiment designed by L9（33）：treatment time was 5min,treatment pressure was 400Pa,and treatment power was 30W.There is no significant increase in the dry-tensile and zero-span indexes,while the wet-strength index increased by 35.8%.The fundamental mechanism of wet-strength development for low temperature plasma treated Pinus massoniana KP fibers was explored by XRD,XPS,AFM and SEM surface analysis technologies.This study indicated that low temperature plasma treatment increased the occurance of oxidized functionalities along with surface cleaning to remove contaminants,extractives and possibly lignin,but the bulk properties of fiber remained unchanged.The new formed covalent crosslinking leaded to increases in the wet-strength index.
