Our GRS certified recycled polyester staple fiber is spun from 100% traceable recycled PET bottle flakes (zero virgin polyester chips added) with specialized food-grade siliconized oil surface finishing. The 0.9D ultra-fine micro denier specification, 22mm short cut length and premium siliconization work synergistically to replicate the cloud-like soft hand feel and high-loft bulk of natural down, while solving core pain points of standard recycled fibers: stiff texture, high static buildup, and high friction coefficient. It is the cost-effective, eco-friendly alternative filling material for mid-to-high end home textile, apparel and toy production.
Pain Point: Manufacturers and brand owners face increasingly strict environmental compliance mandates in EU and North American markets, with non-negotiable demands for traceable, certified sustainable materials that uncertified standard recycled fibers cannot fulfill.
Solution: 100% GRS certified recycled PET bottle flakes as the sole raw material, with full end-to-end supply chain traceability and no virgin material added.
Verifiable Evidence: Complete GRS global recycling standard certification reports are available for every batch, with full compliance to EU REACH regulations, enabling seamless access to global sustainable consumption markets.
Pain Point: Conventional recycled micro denier fibers commonly have stiff, rough hand feel, failing to meet the strict tactile requirements of mid-to-high end faux down and skin-friendly filling products.
Solution: 0.9D ultra-fine denier design paired with specialized siliconized surface treatment, matched with 22mm faux down dedicated short cut length and optimized 3D crimp structure.
Verifiable Evidence: Finer than conventional 1.2D fibers, it delivers a near-natural down feel with zero skin irritation, serving as a high cost-performance replacement for premium faux down materials and cutting raw material costs significantly.
Pain Point: Standard filling fibers are prone to tangling and static buildup during processing, reducing production efficiency, while finished products often pill, clump and trigger end-user after-sales complaints.
Solution: Precision siliconized finishing with controlled oil content (0.25%-0.35%), optimized low crimp setting, and stable breaking tenacity ≥3.2cN/dtex.
Verifiable Evidence: Minimal static and fiber breakage during opening, improved production efficiency, and long-lasting bulk and smoothness with reduced pilling, effectively lowering end-user complaint rates.

We operate a strict ISO 9001:2015 certified quality management system, with every batch of our siliconized polyester staple fiber undergoing rigorous third-party laboratory testing. Our products hold STANDARD 100 by OEKO-TEX® certification, GRS global recycling standard certification, and comply with all major international environmental and safety regulations, ensuring consistent premium quality for every bulk order.
Founded in 2015, we are a fully integrated polyester fiber manufacturer with an annual production capacity of 50,000 tons, guaranteeing stable and reliable supply for large-scale bulk orders. Our production base is located in Jiangyin, Jiangsu, just 120km from Shanghai Port, enabling fast and cost-effective global shipping. We also provide 72-hour technical support for processing optimization, free solutions for on-site production issues, and full customization services for industrial clients.
Yes, complete GRS global recycling standard certification reports are available for every batch of products, fully meeting the sustainable procurement requirements of global mainstream markets.
Absolutely. We offer fully customized solutions including different siliconization levels, functional modifications (antibacterial, water-repellent), fiber cross-section types and color specifications for bulk orders.
We recommend using a low-speed opening machine (600-800r/min) in a dry environment to avoid fiber breakage and static buildup, with low-pressure uniform filling to maintain maximum bulk and softness.
