Two-dimensional virgin polyester fiber for Hard Cotton, Carpet Backing & Packaging Padding

Two-dimensional virgin polyester fiber
15D×64MM
Specifications can be customized

Our 15D×64mm 2D crimp virgin solid polyester staple fiber is a high-performance industrial-grade PSF specially developed for heavy-duty nonwoven, engineering material and filling reinforcement scenarios. Manufactured through advanced melt spinning, drafting and precision cutting processes with 100% virgin PET raw material, it delivers reliable high strength, uniform crimp, excellent processability and stable batch quality.

This fiber is widely recognized by nonwoven factories, geotextile manufacturers and automotive interior suppliers worldwide for its consistent performance and superior mechanical properties.

• Civil Engineering & Geotextile - Road/railway base reinforcement, embankment slope protection, landfill isolation, drainage filtration layer, erosion control geotextile
• Furniture & Bedding Industry - Mattress hard support cotton, sofa hard wadding, furniture cushioning padding, firm seat support layer
• Industrial Filtration - Air filter felt, liquid filter media, dust collection filter cloth, industrial wastewater filtration material
• Automotive Interior - Trunk lining, door panel padding, ceiling substrate, sound insulation felt, heat insulation layer
• Packaging & Transportation - Shockproof packaging cushioning, fragile goods protective liner, transport buffer padding material
• Other Industrial Nonwovens - Carpet base fabric, shoe material lining, composite reinforcement layer, thermal insulation cotton substrate

• 100% Virgin PET Raw Material, Stable Batch Consistency

  Produced from food-grade virgin polyester chips without any recycled impurities, this fiber features uniform molecular structure, consistent denier and stable mechanical properties. Compared with recycled PSF, it greatly reduces end breakage, neps and quality fluctuation in production.

• 15D Medium-Coarse Denier, Outstanding Stiffness & Structural Support

  The 15 denier coarse fiber provides excellent rigidity and load-bearing capacity, making it especially suitable for products that require structural support and shape retention. Finished materials maintain dimensional stability under long-term compression, impact and heavy load.

• Precision 2D Mechanical Crimp, Excellent Cohesion & Uniform Web

  The two-dimensional crimp structure delivers reliable interlocking force between fibers. In the carding process, fibers distribute evenly to form a smooth, uniform web with few thin spots and broken ends, improving overall strength and surface quality.

• High Tenacity & Tear Resistance, Reliable for Heavy-Duty Industrial Use

  With breaking tenacity above 3.5 cN/dtex and moderate elongation, the fiber provides excellent tensile and tear resistance for end products. It performs reliably in harsh scenarios such as road base reinforcement and industrial filtration.

• Optimized Antistatic Finish, Low Fly Waste & Smooth Production

  Specially formulated spin finish gives the fiber balanced antistatic performance and smoothness. In high-speed processing, there is minimal fly waste and fiber shedding, keeping the workshop clean and reducing equipment maintenance.

• Excellent Chemical Stability, Wide Adaptation to Harsh Environments

  Polyester material inherently features good acid resistance, alkali resistance, corrosion resistance and mildew resistance. It maintains stable performance in humid, underground, coastal saline-alkali and outdoor exposure environments.
