Problems solved by technology

In addition, the ecological vegetation blanket, which uses crop straw as raw material, is simply cut off, paved into a loose material layer, covered with non-woven fabric or mesh lining material, and then stitched together is also a planting belt product, but Due to the thick raw material of the vegetation blanket, the vegetation blanket is easy to disperse and has poor tensile strength

Embodiment 1

[0049] Vegetation restoration of the present invention uses the manufacture method step of plant fiber base vegetation tape as follows:

[0050] (1) Preparation of wood fiber: Wood is made into wood fiber by chipping and pulping. By controlling the gap between the grinding discs during refining, the wood fibers with slender and thick shapes but without stems are prepared and dried;

[0051] (2) Prepare long fibers: put other long fibers (such as degradable synthetic fibers, or hemp fibers, or degradable synthetic fibers and hemp fibers) into the fiber opener for opening treatment;

[0052] (3) Mixing and opening of materials: After mixing the above raw materials according to the ratio of wood fiber and other long fibers in the weight percentage of 85:15, the mixed fiber opening machine is mixed and opened and sent to the silo of the air-flow paving machine;

[0053] (4) Lay grid-shaped mesh lining material on the surface of the conveying curtain before the composite mesh blan...

Embodiment 2

[0061] The steps of the method are the same as those in Example 1, except that in step (3) according to the product performance requirements, the recycled wood or crop straw raw materials are combined with other long fibers (such as degradable synthetic fibers, or hemp fibers, or degradable synthetic fibers and hemp fibers) Two blended fibers) are mixed in a ratio of 90:10 to form a composite mix.

Embodiment 3

[0063] The steps of the method are the same as those in Example 1, except that in step (3) according to the product performance requirements, the recycled wood or crop straw raw materials are combined with other long fibers (such as degradable synthetic fibers, or hemp fibers, or degradable synthetic fibers and hemp fibers) Two mixed fibers) are mixed in a ratio of 95:5 to form a composite material mixture.

Abstract

The invention discloses a plant fiber-based composite lawn nursery strip coiled material for vegetation recovery and a manufacturing method for the coiled material. The method comprises the following steps of: preparing agriculture and forestry residues into wood fibers by chipping and pulping; conveying at least one of degradable synthetic fibers and natural jute fibers to a fiber opener, and performing opening treatment; mixing the two obtained raw materials in a weight percentage of 85:15-95:5, performing mixed opening by a mixed fiber opener, and blowing air to a bin of a natural plant fiber non-woven airflow paver; paving a latticed mesh liner material layer on the surface of a conveying curtain of the airflow paver; and uniformly paving the prepared fiber mixture to form a compositemesh blank under the action of negative pressure through the airflow paver, covering the formed mesh blank on the mesh liner material, and preparing a basic plant fiber-based composite lawn nursery strip. By adopting an airflow non-woven forming technology, the raw materials for the lawn nursery strip are distributed uniformly and have good interweaving property, and the tearing resistance of thecoiled material is superior to that of the lawn nursery strip coiled material produced by other technology.

Description

technical field [0001] The invention relates to a method for manufacturing a plant fiber-based composite vegetation tape roll for vegetation restoration. Background technique [0002] Greening the environment, preventing soil erosion and desertification is one of the important aspects of national environmental protection. In our living environment, there are still a large number of slopes (such as river embankments, railway and road slopes, etc.) and some engineering bare ground need to be revegetated. Although engineering measures such as concrete slope protection and lattice frame slope protection can effectively prevent the slope from being eroded and destroyed, and prevent water and soil loss, this protection technology is expensive and is not conducive to environmental greening. The usual greening techniques such as afforestation and grass planting are often easily eroded by rainwater in the early stage of greening due to slope factors, and the effect is not very good....
