15D x 32mm Siliconized Hollow Polyester Staple Fiber for Pillow Filling

Product Introduction

This is a high-performance polyester staple fiber specifically designed for pillow and filling applications. Each parameter in its name represents a key characteristic:

• 15D (15 Denier) – A thicker fiber that provides excellent support and resilience, resisting collapse over time. Compared to fine denier fibers, 15D offers a firmer structural framework suitable for shape-retaining filling products.

• 32mm Length – A shorter fiber length facilitates the formation of a dense and uniform filling layer, providing a firm support feel in pillows while reducing the risk of fiber migration through fabric.

• Siliconized – The fiber surface is treated with silicone oil or resin, imparting excellent lubricity, softness, and anti-caking properties. The silicone treatment allows fibers to slide against each other, resulting in a bulkier, smoother fill with a down-like silky hand feel.

• Hollow Structure – The fiber has a hollow tubular core that traps a large volume of still air, significantly improving thermal insulation while reducing weight. The hollow structure also enhances compression resilience.

• Polyester Staple Fiber – Offers wash resistance, mildew resistance, quick drying, and shape retention, making it one of the most commonly used synthetic fibers for filling applications.

Applications

This fiber is primarily designed for pillow filling, but can also be extended to the following areas:

1. Pillow Filling (Core Application)

• Hotel Pillows – Silicone treatment makes fibers smooth and non-caking; 15D provides lasting support for high-frequency hotel use

• Memory Pillow Blends – Can be mixed with memory foam or other fibers to adjust firmness

• Children's/Neck Support Pillows – 32mm short fibers resist poking through fabric, suitable for infants and children

• Side Sleeper Pillows – High support of 15D effectively cushions head and neck weight

2. Cushions and Throw Pillows

• Sofa cushions, car seat cushions, office lumbar supports – any filling requiring good support

3. Mattress Toppers

• Mattress comfort layers, mattress pads, folding mattress filling – providing elasticity and breathability

4. Pet Beds

• Pet sleeping mats, pet cave beds – pressure-resistant, not easily flattened, easy to clean

5. Toy Filling

• Stuffed animals or plush toys requiring shape retention – 15D provides good structure

Key Features: 

• • Optimal Processability: The 1.4D x 38mm specification is an industry standard for seamless integration into most textile machinery.

  • Softness & Versatility: Fine denier provides a cotton-like feel, making it suitable for skin-contact applications.

  • Cost-Effectiveness: A highly efficient and economical raw material for large-scale production.

  • Consistent Quality: Ensures uniform performance in blending, spinning, and nonwoven production.

  • Strong Market Demand: The backbone fiber for the massive global hygiene and fast-fashion industries.
