51mm Recycled Hollow Conjugated Fiber

• 100% RECYCLED PSF、SEMI-VIRGIN PSF.
• The special asymmetric cooling forming technologies adopted make the fiber a "permanent" spiral three-dimensional crimp.
• The product has the characteristics of high loftiness, high hollow rate and high resilience. Hollow fiber ensures excellent warmth and hydrophobicity. It has many characteristics better than natural fibers, including softness and smoothness, light weight, sanitation, no harmful substance retention and diffusion, corrosion resistance.

51mm recycled hollow conjugated fiber is a standard medium-to-long staple fiber widely used in filling and nonwoven production. Manufactured from high-quality recycled PET, it combines environmental sustainability, stability, and excellent processing properties. The 51mm fiber length delivers outstanding performance in opening, web forming, and blending processes, providing superior fiber strength and structural uniformity. It is a commonly used specification in the home textile filling and nonwoven industries.

The hollow structure renders the fiber lightweight with superior thermal insulation properties, while its crimped configuration imparts enhanced loft, resilience, and softness. In filling applications, the 51mm fiber forms a plump, soft, and moderately resilient structural layer resistant to clumping. For nonwoven uses, its length enhances fiber bonding strength, resulting in more uniform and stable finished products.
