Sourcing GRS-Certified Recycled Polyester: A Guide for Functional Apparel Brands

Introduction Polyester currently accounts for 57% of global fiber production. While versatile, its reliance on fossil fuels is a major liability for modern brands. Recycled polyester (rPET), primarily derived from post-consumer plastic bottles and pre-consumer textile waste, offers a circular solution that aligns with the 2025 Recycled Polyester Challenge.

Technical Specifications You Need to Know When sourcing rPET for functional clothing, technical parameters are key to ensuring a high-quality end product. Our rPET offerings are tested in-house for:

• Tensile Strength: Maintaining 2.6 to 7.0 g/denier for heavy-duty use.

• UV Resistance: High stability for outdoor applications.

• Dimensional Stability: Ensuring less than 3% shrinkage after industrial washing.

The Importance of GRS Traceability The Global Recycled Standard (GRS) is not just a label—it is a chain of custody. It verifies the recycled content and ensures responsible social and environmental practices during production. We provide full Transaction Certificates (TCs) for every lot, ensuring your brand is protected from greenwashing claims.

Sustainable Blending Options Not every product needs 100% rPET. We offer:

• 30% rPET Blends: For cost-effective sustainability claims.

• 100% rPET: For maximum environmental impact in backpacks and workwear.
