The material is bicomponment, including of reinforcement is PET and matrix is low-melting point PET with using filter water property of non-woven composites, and make pipe for subteITanean irrigation. This is the main purpose of this research. We use pore surface tension for conducting water to each gradation of soil. In order to remedy imperfection of non-water absorbent pipe, we use the property of absorbent and discharge on non-woven composites pipe to consummate the purpose of subterranean irrigation.
