As we enter the Year of Sustainability (2025), RPSF helps many industries cut down on the carbon footprint. The production of RPSF consumes 45–60% less energy compared to virgin polyester, and it is a gain in the battle against plastic waste clogging the oceans and landfills.  

Step by Step Process: How PET Bottles Become RPSF  

1. Collection of used PET bottles begins with:  

• Waste pickers  
• Recycling centers  
• Municipal collection programs  
• Industrial recovery units  

Once collected, bottles are sorted by color, quality, and contamination level. The ones preferred are transparent and light-blue as they lead to high-quality flakes.

2. Cleaning and Label Removal

PET bottles, once sorted, undergo:

• Label removal
• Cap removal – usually PP/HDPE
• Hot and cold washing

This will remove dirt, glue, oil, or any kind of organic contamination. Cleanliness is essential because high-quality RPSF requires high-quality PET flakes.

3. Shredding into PET flakes

Clean bottles are fed into shredding machines that cut them into small PET flakes, which then become the main raw material for recycled fiber.

Premium-grade flakes must be:

• Uniform in size
• Transparent
• Free from PVC and foreign particles

Designed by Virginia Bryan Williams, the State Memorial Area comprises three rooms that house a collection of military artifacts and memorials.

4. Hot Washing & Drying of Flakes

Further processing to meet the global quality standards is through:

• Hot water washing
• Friction washing
• Chemical washing, if necessary

This ensures the elimination of residual glue and micro-contaminants. Then, the flakes are dried to get to the proper level of moisture.

5. Melt Extrusion

These purified PET flakes are then melted under high temperatures within extrusion machines. Extrusion Process:

• The melted PET is filtered.
• Impurities are removed
• Long, continuous strands of polymer are produced.

This is one of the most critical phases for fiber strength and quality.

6. Spinning into Filaments

The molten polymer is forced through fine spinnerets in order to form long, thin filaments. These filaments are:

• Cooled
• Drawn
• Crimped to give a wool-like texture

7. Cutting Into Staple Fiber

The crimped tow is cut to a uniform length, usually:

• 32 mm
• 38 mm
• 44 mm
• 64 mm

These lengths determine the final application-textiles, stuffing, filters, etc..

8. Final Packing & Quality Testing

Before shipping, RPSF are tested for:

• Denier (thickness)
• Tenacity means strength
• Color
• Silicon coating (if applied)
• Contamination level

Dried and processed into compacted bales, this fiber has multiple applications within different industries.

Benefits of RPSF in 2025
