3D Hollow Polyester Staple Fiber (51mm)

This 3D Hollow Polyester Staple Fiber, with a standard length of 51mm, is engineered for superior performance in filling materials. Its unique structure creates air pockets that trap air efficiently, resulting in products with enhanced warmth, resilience, and lightweight comfort—making it ideal for bedding, apparel insulation, and upholstery.

Product Description

Key Advantages:
• Superior Thermal Retention - 3D hollow structure traps air for 30% better heat preservation than conventional fibers.
• Eco-Friendly Performance - Made with 100% recyclable PET materials, certified by OEKO-TEX® Standard 100.
• Enhanced Resilience - Spring-like structure maintains 95% loftiness after 5,000 compression tests.
• Optimal Processability - 51mm length ensures perfect compatibility with nonwoven/flocking production lines.
• Multi-Application - Ideal for winter apparel, home textiles, and automotive sound insulation.

Applications

1. High-End Home Furnishing Fillings
This is the most central application area. The 51mm length is ideal for quilting and filling processes.

• Bedding: Used as filling for pillows, duvets, and mattresses. Compared to solid fibers, hollow fiber bedding is warmer, lighter, and maintains its loft longer.

• Sofas and Cushions: Used to fill sofas, seat backs, and throw pillows, providing a soft, comfortable feel with good resilience and resistance to sagging.

• Plush Toys: Used as stuffing, making toys plumper and improving their hand feel.

2. Apparel and Textiles

• Thermal Apparel Insulation: Can be used as a filling material for padded jackets, parkas, and cold-weather clothing, offering a lightweight, warm wearing experience. It is a cost-effective alternative to down.

• Thermal Underwear and Blankets: Can be used to produce fleece, flannel, and other warm fabrics, or directly as filling for blankets.

3. Technical Textiles

• Filtration Materials: The hollow structure can increase the material's surface area and dust-holding capacity, used for making air or liquid filtration materials.

• Acoustic and Thermal Insulation: Used in sound-absorbing and thermal insulation materials for automotive and construction, utilizing the air pockets for heat and noise insulation.
