8s-40s Recycled Spun Polyester Yarn for Knitting

Product Overview

Our 8s-40s Recycled Spun Polyester Yarn delivers unmatched versatility across textile applications, catering to diverse thickness needs from heavy-duty to lightweight fabrics. Available in coarse (8s) for rugged uses, medium (16s, 20s, 30s) for everyday textiles, and ultra-fine (40s) for delicate items, this yarn balances strength and softness through precision spinning. Crafted from 100% recycled polyester (GRS-certified, sourced from post-consumer PET bottles and industrial polyester waste), it reduces carbon emissions by 50% and water usage by 90% compared to virgin polyester yarns. This makes it a sustainable choice for fashion, home textiles, and industrial applications where performance and eco-credentials are equally valued.

Product Specifications

Product Features

Multi-Count Flexibility: 8s excels in durable industrial fabrics (carpets, canvas); 16s–20s for everyday textiles (hoodies, bed sheets); 30s–40s for delicate items (lingerie, sportswear) and lightweight knits.

High Color Retention: Dope-dyed variants maintain 90% color vibrancy after 100+ washes (ISO 105-C06), outperforming traditional piece-dyed yarns in long-term color stability.

Moisture Management: Hydrophobic polyester fibers wick sweat away from the skin, drying 30% faster than cotton—ideal for activewear and outdoor textiles.

Circular Design: Each ton of yarn recycles 32,000 PET bottles, reducing plastic waste while maintaining 90% of virgin polyester’s strength and performance.

Applications

Athletic Apparel: Compression leggings, moisture-wicking yoga tops, and lightweight running jerseys (using 30s–40s) for breathability and stretch.

Home Textiles: Soft blankets (20s–30s), wrinkle-resistant bed sheets (30s), and eco-friendly upholstery fabrics (16s) for sofas and chairs.

Industrial Use: Heavy-duty filter fabrics (8s), agricultural geotextiles, and rope cores requiring high tensile strength and UV resistance.

FAQ

Q: Can I blend this yarn with natural fibers?

A: Yes. It pairs seamlessly with cotton (30–50% for enhanced softness) and wool (20–30% for warmth), suitable for blended fabrics like cotton-polyester t-shirts.

Q: What is the minimum order for custom colors?

A: 5 tons for standard colors from our shade card; 10 tons for custom Pantone matches, with a 2-week lead time for color sampling.

Q: Does the recycled material affect strength?

A: No. GRS-certified recycled polyester in this yarn retains 90% of virgin polyester’s strength, with tensile test results comparable to industry standards for virgin fibers.

Q: Is it suitable for high-temperature washing?

A: Yes. It withstands industrial washing at 60–90°C without significant shrinkage or strength loss, making it ideal for hospital linens and workwear.
