Can recycled cotton be made into geotextiles?

Recycled cotton can indeed be processed into geotextiles for use, especially in the fields of environmental protection and resource recycling, with certain application value. The following is a breakdown explanation:

1. Technical Feasibility

Aspect	Description
Raw Materials	Made from recycled cotton waste (e.g., discarded textiles/fabric scraps).
Processing	Fibers are cleaned, shredded, and processed into non-woven mats.
Production	Compatible with standard methods like needle-punching or thermal bonding.

2. Performance Characteristics

Property	Advantage/Limitation
Biodegradability	Naturally decomposes, enriching soil nutrients (suitable for ecological projects).
Hydration/Filtration	High moisture absorption controls soil humidity; porous structure filters silt.
Strength/Durability	Lower tensile strength & corrosion resistance vs. synthetics; limited for heavy/long-term use.

3. Suitable Applications

Project Type	Use Cases
Temporary Works	Dust suppression covers, temporary road subgrade separation.
Eco-Engineering	Slope revegetation, erosion control where biodegradability is beneficial.
Light-Duty Uses	Drainage ditches, garden soil stabilization, low-stress filtration.

4. Sustainability & Cost

Factor	Benefit
Resource Recovery	Diverts textile waste from landfills; reduces virgin cotton consumption.
Economic Efficiency	Low-cost raw materials; lower manufacturing energy vs. synthetic geotextiles.

5. Key Considerations

Requirement	Action/Note
Lifespan Management	Select based on project duration; degrades faster than synthetics.
Performance Enhancement	Blend with synthetic fibers or apply natural binders to improve durability.
