Description
Technical field
The present invention relates to ecological geotextiles, belong to textile technology field, particularly relate to a kind of the degradable of sandwich structure
Plant growing protection slope geotextiles and preparation method thereof.
Background technology
In recent years, with the construction of the infrastructure such as China's highway, high-speed railway and the large-scale development in mine,
A large amount of exposed native stone side slopes are formd in these engineering constructions, cause vegetation deterioration and soil erosion, ecological environment is generated
Strong influence.
Traditional side slope protection technology mainly carries out bank protection using the hard materials such as cement and block stone, although water can be reduced
Soil is lost in, but long construction period, cost are high, and is difficult to be afforested again after slope surface hardening.Emerging plant growing protection slope material, although
Shorten construction period, reduce greening difficulty, but since the nutriment that plant growing protection slope material carries is less, water holding capacity compared with
Difference, plant often because lacking nutrient or moisture is unable to normal growth, do not have greening and the effect of ecological protection.It is in addition, existing
Some plant growing protection slope material structures are complex, and process is cumbersome, time-consuming and laborious, limit this technology and prevent in native stone side slope
Application in terms of shield.
In the prior art, a kind of plant growing protection slope material is disclosed in the patent of Application No. " 201120471494.3 ", it should
Material is bonded by upper strata non-woven fabrics and lower floor's grid cloth by binding agent, and wherein the fabric ingredient of non-woven fabrics is terylene, third
Synthetic fibre or acrylic fibers, grid cloth are textile fabric, and binding agent is polyurethane binding, polyvinyl chloride adhesive or polyacrylate
Class adhesive.This kind of slop protection material is conducive to the growth of plant, but because it can not provide the nutriment needed for plant growth, only
Suitable for the ecological revetment of sand ground etc., if for native stone side slope, also turf need to be laid on plant growing protection slope material.For another example, Shen
It please be number to disclose a kind of side slope environmental protection vegetation blanket in the patent of " 201611025775.X ", which includes degradable poly lactic acid
Five layers of film, coir nonwoven layer, jute nonwoven layer, water conservation layer, jute scrim layer etc., jute scrim layer bottom are also set
Have and linked together made of bamboo with cuspidated bamboo nail, five layer materials by sewing quilt machine suture, bamboo nail passes through genuine milk
Glue is fixed on jute screen cloth layer surface.The material structure is more complicated, and process is cumbersome and is difficult to realize mechanization production, it is impossible to
Meet the requirement of current fast-developing side slope protection greening, be not suitable for being widely applied.
The content of the invention
The present invention proposes a kind of degradable plant growing protection slope geotextiles of sandwich structure and preparation method thereof, solves existing
The problem of slop protection material application limitation.
The technical proposal of the invention is realized in this way：
A kind of degradable plant growing protection slope geotextiles of sandwich structure, the geotextiles include being located at uppermost surface layer and position
In nethermost bottom and the plant generating layer between surface layer and bottom, surface layer, bottom are fixedly connected and are formed with plant generating layer
One entirety.
The surface layer and bottom are the fibre web being process by biodegradable fiber.
The plant generating layer is natural plant fibre.
To be process by degradable viscose rayon, the viscose rayon shearing length is 35- for the surface layer and bottom
75mm, fiber number 1.1-6.6dtex.
The natural plant fibre additive amount is 300-1000g/m2.On the one hand plant generating layer can provide for plant growth must
The nutrition wanted on the other hand with superior water retention, can build the environment for being conducive to plant growth.
The surface layer and underlayer thickness are 5-10mm, and it is 20-40mm to plant generating layer thickness.
The geotextiles thickness is 30-60mm, grammes per square metre 600-1800g/m2, natural plant fibre content is 40%-85%.
A kind of preparation method of the degradable plant growing protection slope geotextiles of sandwich structure, includes the following steps：It is pierced using pin
Technique realize surface layer, bottom and plant generating layer between being fixedly connected, be surface layer above, following bottom and its between plant life
Layer is through integral.
The preparation method of the degradable plant growing protection slope geotextiles of the sandwich structure, comprises the following steps：
Step 1：Networking prepares, and fibrous raw material is sent into shredding in opener, big fibre bundle or fiber block, group etc. is made to loosen
The thin fibre web being made of the single fiber of uniform extension is combed into tuftlet, then through carding machine；
Step 2：Lapping is made the thin fibre web laying after combing into certain thickness homogeneous web by lapping device
For bottom, it is online that natural plant fibre is sent to bottom fiber by conveyer belt, plant fiber is made uniformly to be layered on web, and
Reach certain thickness, being then laid with one layer on plant fiber again has certain thickness homogeneous web as surface layer；
Step 3：Pin pierces, and carries out repeated puncture to the composite material after lapping using needing machine, makes the fiber in web mutual
It tangles, and makes two layer web and natural plant fibre layer between it through being connected as one.
The thickness of the web is 40-80mm, and natural plant fibre laying depth is 50-100mm.
In the needling process, needling density is 50-150 thorns/cm2, depth of needling 8-12mm.
By using preceding solution, beneficial aspect of the invention is：Plant growing protection slope geotextiles provided by the present invention
The surface layer of geotextiles, bottom with plant generating layer are fixedly connected and form an entirety, form unique sandwich knot by preparation method
Structure can be fixed effectively and plant generating layer, be conducive to the growth of plant；Meanwhile the present invention in plant generating layer can natural decomposition become fertilizer,
And with higher fertility and water holding capacity, good environment is provided to the growth of plant.It is provided by the present invention to plant raw shield
Slope geotextiles can realize mechanization production, and laying construction is convenient and efficient, and it is public to can be widely applied to mine reparation, railway and high speed
The slope greening and urban landscaping and roof greening on road.
