6.67D Silicone-Free Virgin Hollow Staple , Lightweight Warm Filling Fiber for Bedding & Garment

The 6.67D × 64 mm silicone-free virgin hollow polyester staple fiber solves long-standing pain points in wadding and filling production. Traditional siliconized hollow fibers commonly cause adhesion failure, delamination and surface oil contamination during spray bonding and lamination processes, leading to high defect rates and product quality issues. Ordinary solid polyester fibers lack sufficient loft and warmth, while recycled hollow fibers often suffer from inconsistent quality, impurities and poor batch-to-batch uniformity.

This product addresses these issues with premium virgin material and precision engineering. Its uniform hollow core structure creates abundant air pockets that deliver efficient thermal insulation and fluffy loft at minimal weight. The fiber maintains excellent compression recovery, resisting flattening and clumping even under long-term load, extending the service life of end products.

The 100% silicone-free finish is a critical advantage for bonded wadding applications. Without silicone oil on the surface, the fiber works seamlessly with all types of adhesives and bonding resins, delivering strong, consistent bond strength across the entire fiber web. There is no risk of silicone migration to the product surface, no delamination and no oily residue, making it highly suitable for spray-bonded hard cotton, composite padding and automotive interior components.

At 6.67D medium denier and 64 mm staple length, it is a universal filling grade compatible with nearly all conventional fiber processing equipment. It opens and cards evenly, blows smoothly into fill cavities, and forms uniform fiber webs for wadding production. Strict quality control protocols ensure consistent fiber specifications and performance batch after batch, reducing production waste and quality variation.

As a high-quality, cost-effective filling and wadding solution, it is widely adopted by home textile manufacturers, wadding producers, furniture factories and toy makers. We supply in bulk with stable stock, and support customization of denier, length, hollow ratio and functional modifications such as flame retardant treatment. Samples are available for hand feel evaluation, fluffiness testing, bonding trial and washability verification before placing bulk orders.
