The paper aims to prepare tea bag paper of high air permeability from jute fiber. The optimum mixing ratio of modified system and the best pulping degree were explored by mechanical pulping and modification treatment of NaOH/Urea/ZnO aqueous solution. The changes of dry tensile strength, wet tensile strength, tear strength, air permeability, thickness and tightness of tea bag paper were measured. The tea bag paper also was made a preliminary application and safety evaluation. Tea bag paper with good performance can be prepared from jute fiber between 45~70 ?SR. The optimum ratio of the NaOH/Urea/ZnO m was 6%∶10%∶0.4%. The quality of jute (absolute dry) was 10 g, and the volume of the modified system was 500 mL. Under this condition, the permeability of filter paper was 3868.9 μm/(Pa?s), the tensile strength was 0.60 kN/m. After modification, the hot soak effect of tea bag paper is better than that of unmodified bag paper. The thermal extract test of tea bag paper results show that heavy metals index and sensory indexes accord with the requirement of national standard regulations of drinking water. It is feasible to prepare tea bag paper from jute.
