The utility model discloses a glass fiber filter cloth and polyimide surface layer combined spun -laced filter felt. The spun-laced filter felt is formed by jetting and sticking a polyimide fiber layer on a windward surface of the glass fiber filter felt by using high pressure water flow. The spun-laced filter felt has the advantages that the phenomena that high temperature particulate matters burn filter material is reduced by about 20 percent, the strength is high, the radial strength is larger than or equal to 2000N/5*20 cm, the latitudinal strength is larger than or equal to 2000N/5*20 cm, the air permeability is 3 to 5m3/m2 min, the long-term use temperature is 130 to 240 DEG C, the transient use temperature can reach 240 DEG C, the chemical corrosion resistant performance is good, the size stability is good, the tensile strength is high, the wear resistance and the folding resistance are improved, and the service life is long.
