1. Introduction

Recycled Spandex yarn is an eco-friendly elastic fiber produced from pre-consumer industrial waste generated during traditional Spandex production. Instead of being discarded, fiber scraps and by-products are collected and recycled to start a new life cycle, significantly reducing carbon footprints and conserving natural resources.

The product has passed the Recycled Claim Standard (RCS) certification, which is in line with the global green and environmental protection trends, and can help to enhance market competitiveness of "green" and "environmental protection" as an "environmental friendly enterprise". The product specifications cover from 20D to 1120D, the content of recycled materials is from 20% to 100% generally and it can be customized,no difference in performance from conventional products .

2. Composition

Similar to virgin Spandex, Recycled Spandex maintains a Polyurethane polymer structure. However, the production process differs:

• Source Material: Collected from factory fiber waste (pre-consumer).

• Recycling Process: Waste is dissolved or melted, then purified to remove impurities before being re-spun into new fibers.

• Certification: Usually accompanied by international standards such as the GRS (Global Recycled Standard).

3. Key Characteristics

• Eco-Friendly: Reduces industrial waste and consumes less energy compared to virgin fiber production.

• Comparable Performance: Retains approximately 90% - 95% of the physical properties (stretch, strength) of virgin Spandex.

• Stable Elasticity: Ensures excellent recovery without compromising the garment's shape or fit.

• Brand Value: Enables fashion brands to achieve "green" certifications and appeal to environmentally conscious consumers.

5. Applications

• Sustainable Fashion: T-shirts, stretch denim using recycled-blend fabrics.

• Activewear: Yoga and gym gear for "Eco-friendly" product lines.

• Swimwear: Combined with recycled Polyester (from plastic bottles) to create 100% "green" swimwear.

• Intimate Apparel: Providing comfort and environmental purpose for next-to-skin products.

6. Conclusion

Recycled Spandex yarn is a testament to how technology can coexist with nature. Although the production process is more complex, the value it brings to the ecosystem and brand image is priceless, driving a circular economy within the textile industry.
