High Quality Black Polyester Drainage Nonwoven Geotextile-manufacture,factory,supplier from China

 Filament polyester nonwoven geotextile plays a role in railroad engineering  Filament polyester non-woven geotextile is a kind of geosynthetic material made of polyester filament fibers with high strength, corrosion resistance, aging resistance and good water permeability.  Filament polyester nonwoven geotextiles are needed for railroad construction mainly because they have a series of excellent properties, which can help enhance the stability and bearing capacity of the soil, and improve the durability and safety of the railroad roadbed.

Quality filament geotextiles grasp the following three points:1, look at the defects. Knitted polyester fabric appearance defects more, serious defects will affect the effect of wearing. Such as leaky needle hole, lack of silk, hook silk, broken head, silk pulling tight and serious weft slanting, etc.. Lighter defects, such as color difference, rolled edge, bad edge, spell silk, knotted knot, color flower, reflection, oil-colored silk, thick and thin silk, etc. Although the cloth with light defects can be worn, but affect the grade of the fabric.2、Look at the appearance.

The characteristics of filament geotextiles are as follows:High strength and high draft: The strength and draft capacity of filament geotextiles are higher than those of ordinary geotechnical materials, and can withstand high loads and stresses in different engineering environments.Acid and alkali resistance, aging resistance: Filament geotextiles have good acid and alkali resistance, are not affected by the environment, and have high durability.Good penetration and good drainage performance: the mesh of filament geotextile can selectively hinder the movement of soil particles, but it does not

Nonwoven geotextile is a kind of geomaterial made of high-strength, corrosion-resistant synthetic fibers through thermal bonding or needle-punching process, and its role and application scope are as follows:1. Filtration: nonwoven geotextile has good filtration performance, which can block the soil particles, so that water can penetrate freely, thus preventing soil particles from being washed away.2. Protective effect: nonwoven geotextile can effectively increase the tensile strength of the soil, prevent soil loss and loosening, and protect the surface structure from erosion and damage.3.

                                                                        Difference between woven Geotextile and non-woven GeotextileWoven Geotextile and non-woven Geotextile are geosynthetics, but their manufacturing processes and materials are different.Woven Geotextile is made of high-strength polyester or polypropylene and other synthetic material fibers through weaving.

One, needle punching non-woven geotextile, specifications 100g/m2-600g/m2 between any choice, the main raw material is made of polyester staple fiber or polypropylene staple fiber, through the needle punching method, the main use is: rivers, seas, lakes and river dikes slope protection, surrounded by the sea to create fields, docks, locks flood control and rescue and other projects, is an effective way to play through the back filtration of soil and water conservation and prevention of pipe surge.Second, needle-punching nonwoven and PE film composite geotextile, specifications have a cloth a f

Geotextile is a geotechnical material used for soil reinforcement and protection. The selection of its thickness and specifications directly affects its use effect and economy. Therefore, the correct selection of suitable thickness and specifications is very important for project quality and cost control.First of all, choosing the appropriate thickness of geotextile requires considering the following factors:1. Load bearing: The thickness of the geotextile is related to the load it bears.

Currently, as our company's export quota increases year by year, business managers increase capital investment. Constantly update production equipment to ensure the production quality of goods and strive to maintain cutting-edge production technology.Now our company's annual production capacity of non-woven geotextiles can reach 10,000 tons, and our company is quietly becoming one of the top global geotextile manufacturers in the world.
