1. Introduction to short fiber needle-punched non-woven geotextiles
Short fiber needle punched geotextile is a type of nonwoven and industrial fabric. It uses polyester short fiber with a fineness of 6-12 denier and a length of 54-64mm as the raw material. It is made into cloth through non-woven production equipment such as opening, carding, messing (short fibers are intertwined), laying (standardized entanglement and fixation), needle punching and other production processes.

3. Performance characteristics of short fiber needle-punched non-woven geotextiles
(1) Utilize the good air permeability and water permeability of geotextiles to allow water to pass through, thereby effectively intercepting sand and soil loss;
(2) Geotextile has good water conductivity and can form drainage channels inside the soil to drain excess liquid and gas out of the soil structure;
(3) Use geotextiles to enhance the tensile strength and deformation resistance of the soil and enhance the stability of the building structure to improve the quality of the soil;
(4) Effectively diffuse, transfer or decompose concentrated stress to prevent soil from being damaged by external forces;
(5) Prevent the mixing of sand, soil and concrete between the upper and lower layers;
(6) Because the network structure formed by the amorphous fibrous tissue is adaptable and mobile, the holes are not easily blocked;
(7) It has high water permeability and can still maintain good water permeability under the pressure of soil and water;
(8) Made of polypropylene or polyester and other chemical fibers as raw materials, it is acid and alkali resistant, non-corrosive, non-moth-eaten, and anti-oxidation;

7. Laying process of short fiber needle-punched non-woven geotextile
(1) Preparation work: Before laying, clean the laying surface to ensure that it is flat, dry, clean, and free of sharp objects and debris.
(2) Fabric laying: Spread and lay the short fiber needle-punched non-woven geotextile according to the design requirements. Make sure the fabric fits snugly to the surface, leaving no gaps or wrinkles.
(3) Fixing and connection: When laying fabric, the edges need to be fixed and connected, usually using fixing nails, joints or special glue.
(4) Overlap and seam processing: During fabric laying, if multiple pieces of fabric are needed for seaming, ensure that the overlap of the seams has sufficient coverage, and use appropriate seam processing methods, such as hot melting, bonding, etc. Make sure the seams are tight.
(5) Leveling and compaction: After the paving is completed, level and compact the paving area to ensure that the geotextile is in full contact with the ground surface and improve the stability and effect of the geotextile.
(6) Acceptance and maintenance: After the laying is completed, acceptance is carried out to check whether it meets the design requirements. At the same time, perform maintenance to ensure that the geotextile remains in good condition during use.
These steps can ensure the effective laying and use of short-fiber needle-punched non-woven geotextiles and improve their functionality and stability in engineering.

9. Green staple fiber non-woven geotextile
In addition to the production of commonly used white staple fiber non-woven geotextiles, Haoyang Environmental Company also produces special green non-woven geotextiles, the difference between green dust-proof geotextiles and green non-woven fabrics is mainly reflected in the application range, production process, production raw materials, product weight, price, characteristics, size, function and other aspects. The following details the differences between the two aspects:
（1） the difference between the scope of application: green dust-proof geotextile (non-woven geotextile suppliers) is mainly used in construction sites bare soil cover, garbage removal, environmental dust control; Green non-woven fabrics are mainly used in agricultural planting, landscaping, tree insulation, vegetable seedling control and so on.
（2）the difference in the production process: the green dust-proof geotextile is made of polyester staple fiber with a denier of 6-12 denier and a length of 54-64mm, which is made by the production process of opening, combing, handling, laying nets, etc. Green non-woven fabrics are composed of directional or random fibers. It is called cloth because it has the appearance and certain properties of cloth.
（3）the difference of raw materials: the raw materials of green dust-proof geotextile (Chinese geotextile custom) are mainly polypropylene, nylon, polyester and other polymer composite fibers. The main raw material of green non-woven fabric is polypropylene, which is produced by high temperature melting, spinning, laminating, hot rolling and other processes.
（4）product weight difference: the weight of green dust proof geotextiles used in construction sites is mostly 80-150 grams, which can play a good dust suppression effect; The weight of the green non-woven fabric used for agricultural planting is mostly 25g-50g, which can fully meet the use effect of vegetable seedling and garden greening. Choosing the right weight of the product can reduce the cost of use.
（5）the difference in price: the price of environmental protection dust-proof geotextile per ton is relatively cheap, and the price of the two has a lot to do with the raw materials used (new materials or new materials).
（6）product characteristics difference: green dust proof geotextile has the characteristics of light weight, corrosion resistance, good dust proof effect, convenient construction, etc. Green non-woven fabric is characterized by moisture, breathable, flexible, easy to decompose, recyclable and so on.
（7）the difference between the role of the product: the role of green dustproof geotextile (geotextile dealer) is mainly dustproof, cover the soil and sand to press the dust, do not let the dust everywhere; The main function of green non-woven fabric is to increase the germination rate of seeds, prevent the breeding of weeds, increase the surface temperature, and shorten the germination time of seeds.
