Eco-friendly 7D 64MM Hollow Conjugate Siliconized Polyester Staple Fiber
20% Lighter Warmth: The hollow core traps body heat and blocks out cold air while being significantly lighter than solid fibers.
Moisture Wicking: Quickly draws sweat away from the skin to keep the user dry, warm, and comfortable (no sticky feeling).
Luxury Drape: Soft to the touch with excellent “fall,” making it more comfortable and easier to manage than heavy traditional fabrics.
PRODUCT DETAIL
In the modern global marketplace, the demand for sustainable materials has transformed the textile and furniture industries. Eco-friendly 7D 64MM Hollow Conjugate Siliconized (HCS) fiber represents the gold standard for environmentally conscious brands that refuse to compromise on quality. This fiber is engineered to provide the luxurious “feather touch” of virgin polyester while utilizing recycled PET waste, effectively bridging the gap between high-performance comfort and environmental conservation.
Produced in the high-capacity recycling hubs of South East Asia and China, Eco-friendly 7D 64MM HCS is manufactured from post-consumer PET bottles and polyester waste. This process redirects plastic from landfills and oceans into a high-tenacity fiber used for premium pillows, comforters, and sofa cushions.
What is 7D 64MM Hollow Conjugate Siliconized Fiber?
The technical profile of this fiber is defined by its specific density and structure, making it the most versatile specification in the bedding and upholstery sectors:
7 Denier (7D): This refers to the fineness of the fiber. 7D is the “sweet spot” for comfort—finer and softer than 15D, but with more structural resilience than 3D microfiber. It is ideal for luxury bed pillows.
64MM Cut Length: This is the standard staple length for industrial carding and blowing machines. It provides enough surface area for the fibers to interlock, preventing the filling from shifting or clumping inside the product.
Hollow Conjugate Structure: The “Hollow” core traps air for thermal insulation, while the “Conjugate” spiral crimp acts like a microscopic spring for permanent resilience.
Siliconized Finish: The fibers are coated with a premium silicone finish to ensure they are “slick” and smooth, providing a luxurious hand-feel.
Virgin vs. Eco-friendly Recycled Filling
Choosing the right feedstock is a critical decision for brands today. Virgin polyester fiberball is made of petroleum oil which will harm the environment, while Eco-friendly Recycled HCS is significantly more sustainable.
Our recycled 7D 64MM HCS maintains the premium features expected in high-end production:
High Bulkiness and Easy Open: Designed for maximum filling power, allowing you to achieve a lofty look with less weight.
Excellent Tenacity: High-density molecular chains ensure the fiber does not break during the industrial opening process.
High Resilience and Durability: The 3D spiral crimp ensures the fiber springs back to shape even after years of use.
Environmentally Friendly: Reduces the carbon footprint of your production line by repurposing PET waste.
The 5 Strategic Advantages of Polyester Staple Fiber (PSF)
Whether you are producing for the bedding, furniture, or apparel industry, Eco-friendly 7D 64MM PSF offers five key advantages:
Does Not Warp: It neither stretches nor shrinks. It has a resilience that other natural fibres do not have; for example, it does not wrinkle. This ensures pillows and cushions stay lofty and never flatten.
Excellent Material Synergy: It can be combined with other materials such as rayon, cotton, wool, or nylon. This increases the quality of the final product, allowing for the naturalness of cotton to be combined with the durability of polyester.
Lightweight Volume: This does not prevent it from being a solid and durable material. The hollow construction ensures the material is 20% lighter than ordinary solid fiber, providing warmth without weight.
Absorbs Less Moisture: This allows it to repel fungus, mould, and bacteria. This not only increases its durability but prevents the generation of bad odors, making it ideal for bedding and home textiles.
Superior Aesthetic Retention: Polyester garments and fillings usually have brighter and more durable colors and prints, ensuring the final product looks premium for its entire lifespan.
Manufacturing Excellence and Application
The production of Eco-friendly 7D 64MM HCS involves a sophisticated polymerization process performed at high temperature and pressure.
After the spinning and drawing process, the polymer becomes staple fibers when cut into the form of “cotton” at the 64MM length. These staple fibers are widely used for industrial use as well as for clothing. They are fabricated into non-woven fabrics through compression or used as high-loft fills for various applications:
Bedding: The primary choice for premium pillows, blankets, comforters, and filling quilts.
Furniture: Used in sofa cushions and furniture padding where a soft, resilient touch is required.
Apparel: Excellent for premium padding in winter casual wear and sportswear.
Industrial: Used in various non-woven fabrics, automobile interiors, and civil/construction materials.
Performance Benefits: Warmth and Wicking
High-quality Eco-friendly HCS provides specialized benefits that significantly improve the end-user experience:
Warm Keeping: The hollow polyester staple fiber is lighter by 20% than ordinary fiber. It prevents air convection within the fiber to keep warm, wrapping warm air and isolating cold air.
Good Hygroscopicity: It can discharge moisture quickly from the body skin and keep dry and warm, reducing the uncomfortable sticky feeling with its special wicking effect.
Soft Feeling and Fall: It brings a bright, soft, and comfortable feeling to the touch. Compared with heavy thermal fabrics, 7D 64MM HCS is more easily wet, dry, and comfortable, exhibiting excellent “fall” or drape.
Conclusion: Sourcing 7D 64MM HCS Globally
Eco-friendly 7D 64MM Hollow Conjugate Siliconized Fiber remains the definitive standard for manufacturers who prioritize a balance of softness, resilience, and sustainability. Its unique spring-like structure and slick silicone finish ensure a high-quality product that is hypoallergenic, machine-washable, and incredibly durable. By sourcing GRS-certified HCS from advanced hubs in South East Asia and China, you ensure your production line is equipped with a material that is technically superior and environmentally responsible.
