Embodiment 1
[0019] Embodiment one: the present invention shows a kind of preparation method specific implementation of road slope protection ecological blanket, comprises the following steps: A, with PP fiber and waste and old natural fiber as raw material, other fiber refers to the naturally degradable fiber that length is greater than 23mm, The PP fibers, waste natural fibers and other fibers are respectively opened by an opener, and then mixed by a cotton mixer after opening, and then carded by a carding machine to evenly distribute the PP fibers, waste natural fibers and other fibers; B. The combed fibers are cross-laid with a web-laying machine. After the web-laying is completed, a needle-punching machine is used for pre-punching and reinforcement to form an ecological blanket base material, and then the ecological blanket base material is needled to form a road slope protection ecological blanket. .
Embodiment 2
[0020] Embodiment two: a kind of preparation method of road slope protection ecological blanket, comprises the following steps: A, with PP fiber and waste and old natural fiber as raw material, other fiber refers to low melting point fiber or bicomponent fiber, PP fiber, waste and old natural fiber and Other fibers are opened with an opener, mixed with a cotton blender after opening, and then carded with a carding machine to evenly distribute PP fibers, waste natural fibers and other fibers; The netting machine is used for cross-laying, and after the netting is completed, the needle punching machine is used for pre-punching and reinforcement to form an ecological blanket base material, and then the ecological blanket base material is thermally bonded to form an ecological blanket for road slope protection.
Embodiment 3
[0021] Embodiment three: a kind of preparation method of road slope protection ecological blanket, comprises the following steps: A, take PP fiber and waste and old natural fiber as raw material, other fiber refers to the naturally degradable fiber that length is greater than 23mm. The PP fibers, waste natural fibers and other fibers are respectively opened by an opener, and then mixed by a cotton mixer after opening, and then carded by a carding machine to evenly distribute the PP fibers, waste natural fibers and natural fibers; B. The combed fibers are cross-laid with a web lapper, and then the fiber web and the base cloth are needle-punched to make the ecological blanket for road slope protection strong; the base cloth includes cotton cloth and PP cloth. The cost of the base cloth is low, and it can be degraded naturally.
