Multilayer non-woven fabric. |
摘要 |
A multilayer non-woven fabric which provides high strength under low distortion or elongation conditions without impairing the draining properties of conventional non-woven fabrics or the ease with which they can be transported or be made to conform to the earth surfaces over which they are laid. The multilayer non-woven fabric disclosed comprises knitted or woven fabric layers and non-woven fabric layers multilaid together; the knitted or woven fabric layers consist of synthetic resin multifilaments oriented at least in one direction and having a tensile elastic modulus of 20GPa or more, preferably 50GPa or more, and a tensile strength of 1.2GPa or more, preferably 1.5GPa or more, while the non-woven fabric layers consist of long or short synthetic resin fibers arranged at random. |
