Hollow Fibers Series: Engineered for Resilience and Warmth
As a Hollow Fibers Series manufacturer, Jiaxing Fuda Chemical Fibre Factory supplies a comprehensive range of recycled polyester hollow staple fibers designed for demanding filling and nonwoven applications. Since 1995, we have focused on differentiated fiber production, integrating PET bottle recycling into our supply chain to offer sustainable solutions without compromising performance.
Our hollow fibers are characterized by a unique hollow structure that traps air, providing superior insulation, resilience, and loft. This makes them ideal for products ranging from bedding and mattresses to sanitary materials and plush toys. With an annual output exceeding 160,000 tons across our production lines, we ensure stable supply for global customers.
Product Range and Application Fit
Range: 3D/7D/10D/12D/15D/25D/45D
Color: raw white/white
Our Hollow Fibers Series includes both conjugated (three-dimensional spiral crimp) and non-conjugated (two-dimensional) variants, available in siliconized and non-siliconized finishes. Each type serves specific end-use requirements:
| Product Type |
Key Specifications |
Typical Applications |
Non-Silicon Hollow Conjugated PSF
(Regular & Harder) |
15D×64mm, high fluffiness, good resilience |
Spray-coated cotton, non-coated cotton, hard cotton for mattresses. The regular grade is softer; the harder grade has better support. |
| Silicon Hollow Conjugated PSF |
7D×51mm, ultra-high elasticity, spiral crimp |
High-loft quilts, pillow cores, sofa and toy filling |
| Non-Silicon Hollow PSF |
45D×64mm, high rigidity, good coverage |
Hard cotton for mattresses, structural filling |
| White Silicon Hollow PSF |
6D×38mm, 6D×51mm, 6D×64mm |
Bedding, apparel insulation, soft toys |
| Super White Hollow PSF |
6D×51mm, enhanced whiteness |
Premium quilts, comforters, visible filling |
| Raw White Conjugated PSF |
3D×64mm, natural color |
Nonwoven fabrics, industrial padding |

Material and Process Considerations
Our hollow fibers are produced from recycled PET flakes, sourced from our own chemical plant in Huaibei, Anhui, which processes up to 50,000 tons annually. This vertical integration ensures traceability and consistent quality. The fibers are manufactured using advanced spinning technology that creates a stable hollow structure, enhancing thermal insulation and reducing weight.
Key material properties include:
- Hollow structure: Traps air for superior warmth-to-weight ratio.
- Resilience: Recovers shape after compression, maintaining loft.
- Crimp: Conjugated fibers feature spiral crimp for enhanced bulk and processability.
- Finish: Siliconized options provide lubricity for easier processing and softer hand feel.
Critical Specifications and Customization
We offer a wide range of deniers (from 1.8D to 45D) and cut lengths (32mm to 64mm) to match your production requirements. Our team can customize fiber specifications, including denier, length, crimp level, and finish, to achieve desired product performance. Whether you need fibers for high-loft quilts or rigid mattress padding, we can tailor the solution.
For nonwoven applications, our hollow fibers can be blended with other fiber types to achieve specific properties. We also provide guidance on optimal fiber selection based on your equipment and end-use.
Quality Assurance and Compliance
We maintain a mature quality management system, with professional laboratories and advanced testing equipment to ensure each batch meets stringent standards. Our certifications include GRS (Global Recycled Standard) and OEKO-TEX, confirming our commitment to sustainability and product safety. We conduct regular testing for fiber fineness, length, crimp, and tensile strength to guarantee consistency.
Information We Use to Configure Your Solution
To prepare an accurate quotation and product recommendation, our team needs the following details:
- Target application (e.g., mattress, quilt, nonwoven fabric)
- Required denier and cut length
- Desired finish (siliconized or non-siliconized)
- Color requirements (white, super white, raw white)
- Production volume and delivery schedule
- Any specific performance criteria (e.g., resilience, loft)
With this information, we can recommend the optimal fiber grade and provide samples for evaluation before mass production.
Packaging and Delivery
Our fibers are packaged in bales, typically weighing around 275-330 kg, wrapped to protect against moisture and contamination. We are located in Jiaxing, approximately 100 km from Shanghai Port, facilitating efficient sea freight to global destinations. We coordinate logistics to ensure timely delivery, with most orders shipped within 2-4 weeks after confirmation.
Frequently Asked Questions
What is the difference between conjugated and non-conjugated hollow fibers?
Conjugated hollow fibers have a spiral crimp due to differential shrinkage, providing higher bulk and resilience. Non-conjugated fibers are straighter, offering more rigidity and support, making them suitable for hard cotton applications.
Can you provide samples before bulk order?
Yes, we can send samples for your evaluation. Please contact our sales team with your requirements, and we will arrange sample shipment.
Are your hollow fibers suitable for food-contact or medical applications?
Our fibers are primarily designed for textile and nonwoven applications. For specific regulatory requirements, please discuss with our team to ensure compliance.
What is your minimum order quantity (MOQ)?
MOQ varies by product and specification. Typically, it is one full container load (about 25 tons). We can discuss smaller trial orders for new customers.
How do you ensure consistent quality across batches?
We implement strict process controls and conduct comprehensive testing on each batch. Our quality system is certified under GRS and OEKO-TEX, and we maintain detailed records for traceability.
