PP Woven Geotextile

Woven geotextiles are manufactured according to ASTM international product standards to provide high tensile strength and low elongation.

 

 

PP Woven Geotextile (polypropylene woven geotextile) is a commonly used geotechnical material, which is made of polypropylene (PP) fibers by weaving. It has high UV resistance, high strength, durability and chemical resistance. It allows the passage of penetrating surface water, prevents particulate matter from clogging drainage systems and minimizes water intrusion into landfills. It is widely used in civil engineering , environmental engineering and water conservancy engineering and other fields.

 

Features 

 

1. High strength: PP Woven Geotextile has high tensile strength and tear strength, providing reliable soil reinforcement and support.
2. Durability: It has good durability and anti-aging properties, and can maintain stability under long-term use and harsh environmental conditions.
3. Water permeability: PP Woven Geotextile has a certain degree of water permeability, which can promote water penetration and drainage and reduce water pressure.
4. Resistance to chemical corrosion: It can resist a certain degree of chemical corrosion and is suitable for environments with acid, alkali or other corrosive substances.
5. Environmentally friendly: PP Woven Geotextile is made of polypropylene material, which is recyclable and reusable.

 

Application

 

1. Subgrade Reinforcement: PP Woven Geotextile can be used for subgrade reinforcement in road and railway projects, providing soil distributed load, shear strength and lateral restraint.
2. Soil protection: It can be used to prevent soil erosion and protect the soil layer, including river bank protection, slope stabilization and soil conservation projects, etc.

Nonwoven geotextiles are a type of geomaterial that, unlike traditional woven geotextiles, are formed by combining fibrous materials in an unordered, random manner rather than by weaving them. Nonwoven geotextiles are typically made from polymer fibers, such as polypropylene or polyester, that are bonded together through processes such as melting the fibers or needling them.

 

Features

 

1. High permeability: Nonwoven geotextiles have high water permeability, which can promote water penetration and drainage and reduce water pressure.

3. Isotropy: Nonwoven geotextiles have uniform physical properties, giving consistent performance whether in the longitudinal or transverse direction.
4. High tensile strength: Although non-woven geotextile does not have a woven structure, its fiber structure and processing technology give it high tensile strength.
5. Wide adaptability: Non-woven geotextiles can be selected from different materials, thicknesses and performance levels according to specific application needs.

 

Application

 

1. Soil Filtration: Nonwoven geotextiles can be used for soil filtration and separation, preventing particle spillage and soil mixing while allowing moisture and gases to pass through.
2. Soil reinforcement: It can be used for soil reinforcement and reinforcement, providing support and shear strength, reducing soil settlement and deformation.
3. Protection and protection: Non-woven geotextiles can be used for river bank protection, dam seepage prevention, slope stabilization and soil conservation projects to protect soil and structures from erosion and damage.
4. Coating and isolation: It can be used for waterproof layer coating, soil isolation and isolation layer construction to prevent mutual penetration and contamination between different materials.
5. Soil stabilization: Nonwoven geotextiles can be used for land surface stabilization, including lawns, land backfills, and vegetation protection.

 

 

 

PET Woven Geotextile (polyester woven geotextile) is a geotechnical material made of polyester (PET) fibers woven. It has high strength, durability and chemical corrosion resistance, and is widely used in civil engineering, environmental engineering, water conservancy engineering and other fields.

 

Function

 

1. Soil Separation: Polyester woven geotextiles can be used as soil separation layers to prevent soils of different particle sizes from mixing. It can effectively prevent finer-grained soil from seeping into coarser-grained soil layers, thereby maintaining the hierarchical structure and stability of the soil.
2. Soil Reinforcement: It can be used for soil reinforcement and reinforcement. The high strength and tensile properties of polyester woven geotextile can provide soil reinforcement and reinforcement effects, increasing the soil's bearing capacity and shear strength.
3. Moisture permeability: Polyester woven geotextile has a certain degree of water permeability, which can promote water penetration and drainage. This is important to remove or control excess moisture in the soil, reduce water pressure and prevent liquid accumulation.
4. Soil Filtration: It can be used as a soil filter layer to prevent particles from overflowing and soil mixing. The finely woven structure of polyester woven geotextile filters out smaller particles while allowing moisture and gas to pass through.
5. Protection and protection: Polyester woven geotextiles can be used for river bank protection, dam reinforcement and soil conservation projects, etc. It protects soil and structures from erosion and damage, providing stability and reliability.
6. Isolation and distributed load: It can be used to isolate the contact of different materials and prevent mutual penetration and contamination between different materials. In addition, polyester woven geotextiles can disperse loads, reduce pressure concentration, and provide even load distribution.
7. Environmentally friendly application: Polyester woven geotextile is made of polyester material, which is recyclable and reusable. By using this environmentally friendly material, the consumption of natural resources can be reduced and the impact on the environment can be reduced.

Woven geotextiles and nonwoven geotextiles are two common geotechnical materials. They have some major differences in manufacturing process, structure and performance:

 

1. Manufacturing process: Woven geotextiles are made by weaving fibers through a textile machine, similar to the weaving process. It has a woven structure, where yarns or fibers are interwoven to form a fabric. Nonwoven geotextiles are made by combining fibers or fibrous materials into a fiber network through physical or chemical methods, without the need for traditional weaving or weaving processes.
2. Structure: Woven geotextile has an obvious interwoven structure of yarns or fibers, giving it a grid-like appearance. It is usually made of long fibers or filaments and can have different weaving structures, such as plain weave, twill, jacquard, etc. Nonwoven geotextiles are made of fibers that form a fiber network structure through hot melting, needling, bonding, etc., and have no obvious textile structure.
3. Physical properties: Woven geotextiles usually have high strength and tensile properties and can provide strong soil reinforcement and support effects. It has high tensile strength, tear strength and puncture resistance. The physical properties of nonwoven geotextiles depend on the material and manufacturing process, but they are generally relatively thin and soft, with lower strength and suitable for lighter-weight applications.
4. Water permeability: Woven geotextiles generally have good water permeability, allowing moisture to penetrate and drain quickly. This is important to remove excess moisture and reduce water pressure. The water permeability of non-woven geotextiles is poor, and appropriate treatment can be carried out to improve the water permeability according to the specific manufacturing process.
5. Application fields: Woven geotextiles are suitable for civil engineering and environmental engineering applications that require higher strength and durability, such as road reinforcement, river bank protection and soil conservation. Nonwoven geotextiles are suitable for lightweight applications such as ground cover control, soil protection, filtration, etc.

 

In summary, there are obvious differences between woven geotextiles and nonwoven geotextiles in terms of manufacturing process, structure and performance. Woven geotextiles have obvious woven structure and high strength, and are suitable for engineering applications requiring higher requirements. Nonwoven geotextiles are suitable for lighter applications due to their softness, poor water permeability and relatively low strength. The selection of appropriate geotextiles should be determined based on specific application requirements and engineering scenarios.
