This research is mainly to use two layers of the 7.0d polyester nonwoven as the base cloth of the upper strata and lower strata, and the selvage wastes of the PP are layered between them. The polyester nonwoven and selvage wastes combine by needle punching and thermal bonding than the nonwoven/selvage wastes compound fabrics are formed. By this production, we can reduce waste quantity of selvage to achieve the environmental protection purpose, and increase the strength of the compound fabric. The results show when the weight of base cloth is 1 50g/m^2, the content of selvage waste in the compound fabric is 10%, temperature of thermal bonding is 220℃, the liner velocity of the thermal compress roll is 0.5 m/min, the compound fabric has best mechanical properties. The stab resistance and the application of the compound fabric in geotextile are evaluated by stab resistance test according to ASTM D4833 standard.
