Product Description
SORONA® Fill is a bio‑based functional fill material manufactured with DuPont’s patented SORONA® polymer. Its core raw material originates from annually renewable plant‑derived feedstock. Adopting precision processing technology, this fill combines spring‑like mechanical performance with eco‑friendly benefits.
Compared with Nylon 6, its production process achieves 30 % lower energy consumption and 50 % reduction in greenhouse‑gas emissions, effectively lowering environmental impact.
Production Process
Renewable crops such as corn serve as feedstock. Starch is extracted and fermented to produce PDO for making SORONA® polymer. The polymer is then processed into staple fibers and further manufactured into soft, lofty fill.
Key Features: Spring‑Like Semicrystalline Molecular‑Chain Structure
- Excellent Shape Recovery The unique spring‑like semicrystalline molecular‑chain structure delivers soft handfeel and long‑term resilience. Anti‑lumping and wrinkle‑recovery rates exceed 90 % even after 50 washing cycles.
- High Loft & Thermal Insulation Lofty fiber structure forms stable air pockets, delivering reliable warmth retention.
Applications
- Home Textiles: Duvets, pillow cores, mattress interlayers (lofty warmth, anti‑lumping, easy‑care performance)
- Apparel: Thermal base layers, sportswear filling, outdoor wear (lightweight, resilient, outstanding recovery)
- Medical‑Care Products: Nursing pads, rehabilitation pillow cores (skin‑friendly, safe, disinfection‑resistant, moisture‑absorbent)
- Household Goods: Cushions, stuffed toys (soft touch, good resilience, eco‑friendly, low‑odor)
Supported by multiple international certifications, the material ensures product safety and promotes green industry transformation.
