Non-woven application in side slope greening

A: the introduction of non-woven non-woven slope ( English name: NonWoven) Also called nonwoven fabric, is composed of directional or random fiber, is a new generation of environmental protection material, has moisture-proof, breathable, flexible, qualitative light, no combustion, easy to decompose, non-toxic non-irritating, rich colors, with low cost, reusable, etc. Such as the use of polypropylene (more Pp material) Grain as raw material, by high temperature melting, spinning, steel, heat the top ranking paper for one-step production. Because of having the appearance of the cloth and some performance and called it the cloth. Non-woven production methods classification non-woven products development forecast characteristic classification introduced daily products non-woven quilt disposables flour hardcover bag fashion shopping bag features and USES cluster development opportunities manufacturer, products are mainly used in highway, railway, water conservancy, electric power, water and soil conservation and environmental greening and other infrastructure areas. Second, the characteristics of non-woven fabric 1) Air permeability, 2) Filterability 3) Heat preservation 4) 5) water imbibition Waterproof 6) Scalability 7) Don't shock 8) Feel is good, soft 10) Resilient and can recover 11) Mass produced, low price, and so on. Three, use non-woven ( 1) Health cloth: gown, protective clothing, XiaoDuBao cloth, mask, diapers, women's sanitary napkin, etc; （ 2) Family decorative cloth, wall cloth, table cloth, bed sheet, bedspread, etc; （ 3) With loaded with cloth, cotton lining, fusible interlining, flocculus, finalize the design, all kinds of synthetic leather base cloth, etc. （ 4) Industrial fabrics: filter materials, insulation materials, cement bags, nonwoven fabric and coated fabric, etc; （ 5) Agricultural cloth: crop protection cloth, base cloth, irrigation cloth, insulation curtain, etc. ; （ 6) Other: space cotton insulation, heat preservation material, linoleum, cigarette filter, bags, tea bag, etc. Four, non-woven fabrics used in slope greening non-woven fabric is an indispensable auxiliary materials in slope greening, is an important factor of soil and water conservation and the growth of the plant community. Slope cover non-woven has rain erosion resistance, moisture, keep warm, moisture, water retention, reduce the effect, such as ultraviolet money shines on seed germination rate, germination speed play an important role, if matching proportion is unreasonable, will not reach the ideal effect. Soil and water conservation is the base of vegetation restoration. Generally refers to the stability of layer, don't fall off, don't loss, have certain resistance to scour capability. So you need to choose non-woven fabric thickness, forming a protective structure from thick to thin. But when the choice must be based on the comprehensive situation of site conditions, give full consideration to the slope, structure type and thickness of replace with out-soil material, non-woven fabric is too thick make harden and substrate layer affect plant growth, if too thin, not keep the effect of soil and water conservation. Vegetation is the core of soil and water conservation. Slope soil long-term solid is formed by plant roots staggered stretch. Expensive and slope water often nervous, irrigation system, non-woven fabric becomes to keep the choice of materials, water play a vital role in construction and later maintenance. 。 But with adhesive, water retention agent matching ratio based on the application of slope environment and other materials. 1:5: non-woven unique advantages non-woven fabric cost is low, the price cheap, use it as a packaging materials, additional cost is small. 2: non-woven fabric air permeability, water permeability is strong, with non-woven packaging seedlings can be planted directly, don't have to be demolished packaging, and furthermore, compared to plastic bags, has an irreplaceable role. 3: non-woven fabric stretch, matter after packaging transportation, loading and unloading will not drop in the soil, loose tuo, occasionally come loose soil condition, don't understand packaging will not affect seedling quality. 4: non-woven packaging seedlings planted directly, high survival rate of seedlings, plant roots over a period of time will penetrate the non-woven non-woven its price is much higher than block, plastic bags, straw rope practical application more and more '
