An elastic non-woven fabric which is bonded to an elastic cloth after pre-drawing the film, and comprises an elastic film and a second elastic cloth. The elastic film has a stretching range of 0 to 300%. Each elastic cloth has an elongation of 150 to 300%. The two elastic fabrics are respectively attached to the upper surface and the lower surface of the elastic film which is stretched to the stretching width in advance while maintaining the natural width thereof. Therefore, after the elastic film is pre-stretched in the present invention, the two elastic cloths are attached to the elastic film, so the elastic non-woven fabric can have high elongation and high tensile strength, the surface does not cause serious wrinkles, and is not easily pulled. broken. Since the elongation of the elastic non-woven fabric is greatly increased, the user can use a smaller piece width, and each of the cylindrical mother rolls can be divided into more cylindrical small rolls to improve production efficiency.一種預拉薄膜後與彈性布貼合的彈性不織布，包括一彈性薄膜及二彈性布。彈性薄膜的拉伸幅度為0~300%。各彈性布具有150~300%的延伸率。該二彈性布在維持其自然寬度的條件下分別貼合在被預先拉伸至拉伸寬度的彈性薄膜的上表面及下表面。藉此，本創作預先拉伸彈性薄膜以後，才將該二彈性布貼合於彈性薄膜，所以彈性不織布能夠具有高延伸度和高抗拉強度，表面不會產生嚴重皺褶，也不易被扯破。由於彈性不織布的延伸度大幅提升，故使用者能夠使用更小的裁片寬度，每個筒狀母卷可分裁成更多筒狀小卷，提高生產效率。
