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.

Our 8s-40s Recycled Spun Polyester Yarn is a versatile, circular-economy focused textile raw material designed for full-spectrum textile production, from heavy-duty industrial fabrics to delicate lightweight knits. Made from 100% GRS-certified recycled polyester (with 95% post-consumer content sourced from waste PET bottles and industrial polyester scraps), this 100% recycled polyester knitting yarn retains 90% of the tensile strength of virgin polyester, while cutting carbon emissions by 50% and water usage by 90% compared to virgin polyester alternatives. With yarn counts ranging from coarse 8s to ultra-fine 40s, it adapts seamlessly to diverse manufacturing needs for large-scale textile producers.
This multi-count recycled spun yarn eliminates the need for multiple raw material SKUs, with 8s optimized for heavy industrial fabrics, 16s–20s for everyday textiles, and 30s–40s for fine, soft knits. It supports flexible production scheduling for bulk manufacturers, reducing inventory costs and procurement complexity.
Our dope-dyed variants maintain 90% color vibrancy after 100+ industrial washes (ISO 105-C06), with pilling resistance up to Level 4–5 (ASTM D3512). It withstands high-temperature (60–90℃) industrial washing without shrinkage or strength loss, ensuring consistent product performance for end-users.
With full GRS and OEKO-TEX® Standard 100 certification, this GRS certified recycled polyester yarn for socks and apparel offers full raw material traceability. Every ton of yarn recycles approximately 32,000 waste PET bottles, helping brand owners and fabric factories meet global ESG targets and circular economy requirements.

Our bulk dope dyed polyester yarn is produced via a precision ring spinning process, with a fully closed-loop production line. We sort, clean, and sterilize post-consumer PET waste, extrude it into high-quality staple fibers, then spin the fibers into yarn with automated, calibrated equipment. Our quality control team conducts 12+ inspection points across the entire production process, including fiber purity, twist uniformity, tensile strength, and color consistency, ensuring batch-to-batch deviation is controlled within 5% of industry standards for uninterrupted bulk production.

This yarn is compatible with warp knitting, weft knitting, and circular knitting machines, and can be seamlessly blended with cotton, wool, and other natural fibers for enhanced performance. We recommend conducting blend ratio and dyeing compatibility trials before mass production. Store the sealed yarn bags in a cool, dry warehouse, away from moisture, corrosive gases, and open flames, with stacking height not exceeding 10 layers. Use opened packages as soon as possible to avoid moisture absorption.
Yes, it pairs perfectly with cotton (30–50% blend for enhanced softness) and wool (20–30% blend for added warmth), ideal for blended t-shirts, sweaters, and loungewear.
