• filtration performance
• glass fiber filter paper
• plant fiber
• tensile strength

In this study，plant fiber was added to the glass fiber composed of chopped glass fiber and fine glass wool，and plant fiber reinforced glass fiber filter paper was prepared by dispersing，molding，dipping，drying，and other processes. The effects of plant fiber type，fiber propor? tion，and fiber beating degree on the tensile strength，filtration performance，and formation of filter paper were investigated. The results showed that the addition of plant fiber effectively improved the tensile strength of glass fiber filter paper，but had an adverse effect on its filtration perfor? mance and formation. The optimal process conditions for preparing plant fiber reinforced glass fiber filter paper were as follows：the proportion of hardwood fiber was 5%，and beating degree 40 °SR. Under these conditions，the tensile index of glass fiber filter paper was 25. 3% higher than that of the blank sample，and the quality factor was maintained at a high level of 0. 0220 Pa?1 ? 2023 China Technical Association of Paper Industry.
