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. |
