In order to develope new composite gcotextiles with good comprehensive properties, the needle - punched composite geotextilcs and adhesive bonded composite gcotextiles were made in the factory and laboratory separately. The two processing methods were studied and the mechanical and hydraulic properties of the two kinds of products were tested and compared. The experimental results show that the breaking strength of needle - punched composite gcotextiles is much lower than that of adhesive bonded composite geotextilcs and the latter also have better hydraulic properties than the former which is used in factory now, thus the conclusion was got that adhesive bonding method is possible.
