Abstract：Inthissudy，modifiedfiber（CRF）wasprepardbymechanicaltreatmentoftempooxidizedcellosewithcoloidalmillda newtypefabsorbentsatarymaterial（RF-PMA-Ag-SAM）withgoodantibacterialpropertisaspreparedbypolymerzationwithcyic acid（AA），poly malic acid（PMLA），and silver nitrate （ AgNO3 ）under UV light. The results showed that CRF，AA，and PMLA were successfully copolymerized，and Ag existed in two valence states of Ag and Ag0 . At the addition amount of 15% CRF，the CRF-PMLA-AgSAM prepared with the addition amount of 1% PMLA and 1% AgNO 3 had good absorption retention rate for normal saline，with water absorption rate of 128g/g and water retention rate of 76g/g ，which had obvious inhibitory effect on Staphylococcus aureus and Escherichia coli，and the diameter of inhibition zone was 9.5 and 9.8 mm，respectively.
