One: Introduction to Slope Non-woven Fabric
Non-woven fabric (English name: NonWoven), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, and non-combustible. Toxic, non-irritating, rich in color, low price, recyclable and other characteristics. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. Non-woven production method classification Non-woven product classification development forecast characteristics introduction daily products non-woven patchwork disposable products flour hardcover bags fashion shopping bags characteristics and use development opportunities clusters of manufacturers, products are mainly used in roads, railways, water conservancy, Electricity, water and soil conservation and environmental protection and greening and other infrastructure construction fields.
Second, the characteristics of non-woven fabrics
1) Breathability 2) Filterability 3) Heat retention 4) Water absorption 5) Waterproof 6) Stretchability
7) Not untidy 8) Good hand feel, soft 10) Elastic and recoverable 11) Low price, mass production and so on.
Third, the use of non-woven fabrics
(1) Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.;
(2) Home decoration cloth: wall cloth, table cloth, bed sheet, bedspread, etc.;
(3) Follow-up cloth: lining, adhesive lining, wadding, shaped cotton, various synthetic leather base cloth, etc.; (4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, Covering cloth, etc.;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
(6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
Fourth, the application of non-woven fabrics in slope greening
Non-woven fabric is an indispensable auxiliary material in slope greening, and an important factor for soil and water conservation and plant community growth. Slope cover non-woven fabric can have the effects of rain resistance, moisturizing, warming, moisturizing, water retention, and reducing direct ultraviolet radiation. It has an important role in seed germination rate and germination speed. If the selection ratio is unreasonable, it will Can not achieve the desired effect.
Soil and water conservation is the foundation of vegetation restoration. Generally refers to the stability of the capping layer, which does not fall off, does not run off, and has a certain resistance to erosion. Therefore, the thickness of the non-woven fabric needs to be selected, from thick to thick to form a protective structure. However, the selection must be based on the comprehensive situation of the site conditions, and fully consider the site slope, the structure type and thickness of the soil material. If the non-woven fabric is too thick, the matrix layer will be compacted and affect the growth of plants. If it is too thick, it will not be able to maintain water and soil. effect.
The vegetation community is the core of soil and water conservation. The long-term stability of the soil and water on the slope is formed by the staggered extension of plant roots. However, slopes often have tight water sources and expensive irrigation systems. Non-woven fabrics have become a necessary material for maintaining water and fertilizer, and play a pivotal role in construction and post-maintenance. . The matching ratio with adhesives and water-retaining agents depends on the slope environment and the application of other materials.
Five: Unique advantages of non-woven fabrics
1: The cost of non-woven fabric is low, the price is cheap, and the additional cost is small when it is used as a packaging material.
2: The non-woven fabric is breathable and has strong water permeability. The seedlings packed in the non-woven fabric can be directly planted without removing the packaging. Compared with the nutrition bowl and the plastic bag, it has an irreplaceable effect.
3: The non-woven fabric has strong stretchability, tightly packed and transported, there will be no soil falling, loose lumps, and occasional loose soil during loading and unloading, and the quality of seedlings will not be affected if the packaging is not solved.
4: Non-woven packaging seedlings are directly planted, the survival rate of the seedlings is high, and the plant roots will penetrate the non-woven non-woven fabric within a period of time. Its cost performance is much higher than that of the nutrient bowl, plastic bags, and straw ropes. more'
