1.2D x 51mm Optical Brightened Hollow Polyester Staple Fiber for Filling

Product Description

This product is a high-quality polyester staple fiber specifically designed for filling applications. Each parameter in its name represents a key physical or optical characteristic:

• 1.2D (1.2 Denier)
  The fiber is very fine and soft, offering a smooth hand feel, good drapability, and excellent softness, making it ideal for applications where touch comfort is critical.

• 51mm Length
  A medium-long fiber length that facilitates the formation of a three-dimensional network structure during carding, web forming, and filling processes, enhancing resilience and bulkiness.

• Optical Brightened
  Optical brighteners are added during production, resulting in a brilliant white appearance without the need for post-bleaching. This is especially suitable for white or light-colored filled products.

• Hollow Structure
  The fiber has a hollow tubular core that traps more still air, thereby improving thermal insulation and warmth retention while reducing weight per unit volume and increasing bulkiness.

• Polyester Staple Fiber
  Offers good elasticity, wash resistance, moisture and mildew resistance, and shape retention, making it one of the most widely used synthetic fibers for filling applications.

Applications

This fiber combines softness, optical brightness, hollow-core warmth retention, light weight, and high bulk, making it ideal for the following filling products:

Bedding – Pillows, quilt fills, mattress toppers, down-alternative fills

Home Textiles – Cushions, throw pillows, sofa pads, seat cushions, bean bag fills

Apparel Filling – Padded jackets, insulated linings, winter coats, ski wear fills

Toy Filling – Stuffed animals, fabric dolls, plush pillow toys

Filtration & Sound Insulation – Automotive interior soundproofing pads, air filter media (hollow structure enhances porosity)

Product Advantages Summary

• ✅ High Whiteness: Optical brightening provides a brilliant white finish without post-bleaching

• ✅ Soft & Comfortable: 1.2D fine denier offers a feel close to natural down

• ✅ Lightweight & Warm: Hollow structure delivers good thermal insulation with low weight

• ✅ High Bulk & Resilience: The 51mm length combined with hollow structure resists collapse over long-term use

• ✅ Easy Processability: Suitable for carding, airlaid, bonded wadding, thermal-bonded nonwovens, and other processes

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.
