3D Recycled PET Composite Hollow Staple, with silicone oil Fluffy Resilient Fiber for Nonwoven Filter

The 3D×32mm silicone-finished recycled composite hollow staple fiber is engineered to address key challenges in sustainable textile production. As brands increasingly require GRS-certified raw materials to meet environmental regulations and consumer demand, ordinary recycled single-layer hollow fibers often suffer from poor crimp memory, high fly, and inconsistent processability on high-speed lines. Virgin composite hollow fibers deliver reliable performance but come with higher cost and a larger carbon footprint.

This product balances sustainability, processability, and value. Its composite bi-component spinning structure creates a permanent 3D spiral crimp with excellent shape memory, so the fiber maintains its loft and resilience through carding, spinning, and end use. This is a significant upgrade over standard single-layer recycled hollow fibers, which tend to lose crimp and flatten during processing.

The controlled silicone surface finish is engineered for high-speed manufacturing. By reducing fiber-to-fiber friction, it improves fiber flow through openers, cards, and spinning frames, resulting in fewer end breaks, less fly waste, and smoother production runs. This is especially beneficial for fine denier spinning and high-speed nonwoven lines where process consistency is critical.

At 3D fine denier and 32mm short staple length, it is optimized for fine textile and nonwoven applications. It produces soft, uniform yarns with low hairiness and smooth nonwoven webs with consistent density, meeting the quality standards of premium textile and hygiene products.

Manufactured under GRS-compliant management systems with full traceability, every batch undergoes strict testing for denier tolerance, length uniformity, crimp stability, oil content, and tensile strength to ensure consistent performance. We supply in bulk with stable stock and support customization of denier, length, oil content, and functional modifications such as anti-bacterial or flame-retardant treatment. Samples are available for spinning trials, process evaluation, and performance testing before placing bulk orders.

• GRS-Certified 100% Recycled PET, Traceable & Low-Carbon Produced from traceable post-consumer PET bottle flakes and certified to the Global Recycled Standard (GRS), it reduces plastic waste and carbon footprint compared to virgin polyester fibers. It supports brands in meeting ESG targets, eco-labeling requirements, and sustainable procurement policies.
• Composite Hollow 3D Crimped Structure, Durable Resilience & Loft The composite bi-component structure creates a permanent three-dimensional spiral crimp with strong crimp memory. It delivers consistent fluffiness, compression recovery, and air-trapping warmth, maintaining stable performance through processing and end use — better than ordinary single-layer hollow recycled fibers.
• Optimized Silicone Finish, Smooth Processing & Low Fly A controlled silicone lubricant coating is applied to the fiber surface to reduce inter-fiber friction. This enables smoother feeding and processing on high-speed spinning, carding, and nonwoven lines, with less fiber breakage, fly, and tangling, improving production efficiency and reducing material waste.
• 3D Fine Denier + 32mm Short Staple, Optimized for Fine Textiles 3D fine denier delivers soft, delicate yarns and uniform nonwoven webs, while the 32mm short staple length is specially optimized for ring spinning, air-jet spinning, and fine nonwoven processes. It produces even, low-hairiness yarns and smooth, consistent fabric surfaces.
• Stable Batch Consistency, Reliable Mass Production Strict in-process quality control ensures uniform denier, length, crimp, and oil content across every production batch. Consistent processing performance reduces downtime and quality variation, supporting stable high-volume manufacturing for industrial customers.
• Versatile End Uses, Cost-Effective Virgin Alternative Matches virgin composite hollow fiber in core processing and performance metrics at a more competitive cost. Suitable for fine yarn spinning, hygienic nonwovens, filter media, precision toy filling, and garment linings, covering a wide range of textile and industrial applications.
