In the industrial fiber market, one of the most critical factors determining performance is the denier, or thickness, of the fiber.

The 18D (18 Denier) polyester staple fiber stands out as a high-performance fiber widely used in applications that demand durability and structural integrity—such as automotive components, construction materials, furniture padding, and industrial fillers.

What is 18D Polyester Staple Fiber?

18D refers to a fiber with a weight of 18 grams per 9,000 meters in length, indicating a relatively thick and robust fiber structure.

While typical PSF ranges from 1.5D to 15D, the 18D fiber offers enhanced thickness and density, making it ideal for building stronger and more resilient nonwoven structures.

Thanks to these properties, 18D PSF is highly valued in applications requiring high compression resistance, excellent recovery, and superior bulkiness.

Key Benefits of 18D PSF Buyers Should Note

High Strength & Abrasion Resistance: Ideal for long-lasting shape retention in floor mats, automotive linings, etc.
Excellent Volume Formation: Achieves sufficient thickness with less material, offering cost efficiency
Thermal Bonding Compatibility: Easily blends with low-melting fibers (LMF) to create adhesive-free composite materials
Eco-Friendly Potential: Can be manufactured from recycled polyester materials, supporting sustainability goals

Main Application Areas

Building & Construction: Ceiling and wall acoustic insulation, thermal barriers
Furniture and Bedding: Mattress pads, sofa stuffing, quilt filling
Industrial Nonwovens: Packaging, anti-vibration pads, shock-absorbing layers
