Two kinds of polyestcr needle-punched filter media with diflercnt density were finlshed by PTFE emulsion . The effects of eight different parameters in PTFE emulsion finishing process on permeability of two kinds of filter materials were studied , involving impergeating temperature , impregnation time , PTFE emulsion concentration , calendar pressure , pre-drying temperature and time , curing temperature and time.The optimum finishing process for the permeability of filter material with loose structure was as follows, the dip time was 15 min, the calendar pressure was 0.2 MPa, the pre-drying temperature was 100 ℃, the pre-drying time was 5 min, the curing remperature was 180 ℃, the curing time was 7 min.The optimum finishing process for the permeability of filter masterial with compact structure was as follows, the dip time was 15 min, the calendar pressure was 0.5 MPa, the pre-drying temperature was 80 ℃, the pre-drying tiem was 10 min, the curing temperature was 160 ℃, and the curing time was 3 min.
