Abstract：Toadesstdeterioratioofbqualitydmehaicalstrengthegradationduringwastepaperecyngthissudydeelopedacholinclorde/glyceroloxalicacidterarygreensolvetsystemforfberregenerationTroughsinglefactorexperiments，itwas found that the optimal processing conditions were as follows：moisture content of wast paper pulp of 10% ，pretreatment，temperature of （204 ，pretreatment time of 6O min，and solid-liquid ratio of 1：10 .Under these conditions，the tensile index，tear index，and folding endurance of the paper was 15.8 N·m/g ， 4.27mN⋅m2/g and 22 times，respectively. Comprehensive structural characterization analysis showed that the cellulose crystallinity index decreased from 48. 5% to 40.8% ，accompanied by substantial increases in surface porosity.
