Short Fiber Needle Punched Polyester Non Woven Geotextile Fabric For Landscape Drain

Short Fiber Needle Punched Polyester Nonwoven Geotextile Construction Fabric For Landscape Drain

Description:

Staple fiber PET nonwoven geotextile is permeable fabric which has the ability to separate, filter, reinforce, protect, or drain. It is made from 100% polyester(PET) staple fiber without chemical additives and heating. PET material itself has a good UV and chemical resistance properties. It is an environmental friendly construction material.

Polyester Nonwoven Geotextile Ecological benefits of application scenarios

1. Soil and water conservation and ecological restoration

It is used in river bank protection, landfill anti-seepage and other projects to isolate pollutants, prevent soil erosion and promote ecological recovery.

2. Replace traditional high-pollution materials

For example, replace plastic film as grass-proof cloth in agriculture to reduce white pollution; replace concrete or sand and gravel isolation layer in construction projects to reduce carbon emissions.

3. Water permeability and soil improvement

Its porous structure can promote soil air permeability and water permeability, improve soil quality and support plant root growth, and help sustainable agriculture.

Degradability and environmental controversy

1. Limited biodegradability

Polyester is a petroleum-based synthetic fiber. It takes decades for it to degrade naturally and needs to rely on a recycling system to avoid environmental residues.

2. Industry innovation direction

Some companies are developing degradable polyester modified materials (such as adding photolysis agents) or blending with natural fibers to improve environmental performance.

Construction precautions

1. Key points for laying

·Clean up debris from the ground to ensure that the base is flat; overlap width ≥ 20cm, and the seams are fixed by hot melt or stitching.

·Cover with a protective layer (such as soil or gravel) to prevent aging caused by direct ultraviolet radiation.

2. Maintenance and inspection

·Regularly check for damage or deformation, and repair or replace in time.

Market and policy support

1. Environmental certification

Mainstream products have passed ISO 14001 environmental management system certification and meet the EU RoHS directive's restrictions on hazardous substances.

2. Policy promotion

China's "Technical Specifications for the Application of Geosynthetics" and other standards encourage the use of recyclable geotextiles and promote the popularization of environmentally friendly materials in infrastructure.

Summary:

Polyester nonwoven fabrics have shown strong environmental performance through material recycling, production process optimization and ecological application, but their degradation limitations still need to be further broken through through technological innovation and improvement of the recycling system. When selecting products, products with recycled fiber components or modified and degradable materials can be given priority.
