HCS 7D 64mm Regenerated Polyester Staple Fibre (PSF)
Ultra-Light Warmth: 20% lighter than solid fiber; its hollow core traps heat and blocks cold air for superior insulation.
Dry Comfort: Quick-wicking technology pulls moisture away from the skin to prevent a sticky feeling.
Premium Feel: Exceptionally soft with a beautiful “drape” (pendency) that feels lighter and more comfortable than heavy traditional fabrics.
Versatile Blends: Perfect for high-grade thermal underwear, sportswear, and winter gear when mixed with cotton, wool, or viscose.
PRODUCT DETAIL
In the evolving global textile market, the demand for sustainable raw materials has moved from a preference to a primary requirement. HCS 7D 64mm Regenerated Polyester Staple Fibre (PSF) stands at the intersection of environmental responsibility and industrial excellence. This specific grade of regenerated fibre is engineered to provide the high-density performance and soft hand-feel traditionally reserved for virgin materials, making it the premier choice for high-end bedding, furniture, and toy manufacturing.
By sourcing high-quality regenerated fibre from the advanced recycling hubs of South East Asia and China, manufacturers can access a product made directly from post-consumer PET bottles and polyester waste that meets the highest standards of tenacity and resilience.
What is HCS 7D 64mm Regenerated Polyester Staple Fibre (PSF)?
The “7D 64mm” specification is widely regarded as the most versatile dimension for consumer comfort products. The 7 Denier thickness provides a fine, silk-like texture that is significantly softer than the coarser 15D grades. When combined with a 64mm cut length, the fibre offers the ideal surface area for industrial carding and blowing machines, ensuring a smooth, consistent fill that does not bunch or clump.
The “HCS” designation—Hollow Conjugate Siliconized—indicates a three-dimensional spiral crimp and a hollow core. This structure is the secret behind the “High Quality” label, as it allows the fibre to trap significant amounts of air, providing superior loft and a “bounce-back” memory that ensures pillows and cushions return to their original shape instantly after use.
Regenerated vs Virgin Polyester: The Quality Standard
A common misconception in the industry is that regenerated fibre is inferior to virgin polyester made from petroleum oil. However, modern regeneration technology has closed this gap. While virgin production relies on new oil extraction which can harm the environment, regenerated fibre is significantly more eco-friendly.
High-quality regenerated 7D 64mm fibre offers features that are indistinguishable from virgin grades:
High Bulkiness: The fibre is designed for an “easy open” process, ensuring maximum filling power with minimum material weight.
Excellent Tenacity: High tensile strength prevents fibre breakage during high-speed manufacturing.
Feather Touch: The premium siliconized finish provides a light and soft texture that mimics natural down.
Anti-Static & Odorless: These fibres are treated to be anti-static and do not absorb foreign odors, making them ideal for home textiles.
The Five Strategic Advantages of Regenerated PSF
For manufacturers considering a switch to high-quality regenerated 7D 64mm HCS, there are five key advantages to consider for your production line:
Superior Dimensional Stability Regenerated polyester staple fibre does not warp. It neither stretches nor shrinks, possessing a resilience that other natural fibres do not have. This ensures that the final product, whether a luxury pillow or a comforter, maintains its aesthetic and structural integrity over years of use.
Excellent Blending Versatility This fibre can be combined with other materials such as rayon, cotton, wool, or nylon. Blending increases the quality of the final product and allows for a multiplicity of uses, such as creating a functional textile that takes advantage of the naturalness of cotton combined with the durability of polyester.
Lightweight Construction Being light does not prevent this fibre from being a solid and durable material. The hollow construction ensures that the material remains lightweight, which is a critical selling point for premium duvets and high-performance outdoor apparel.
Moisture and Microbial Resistance Regenerated PSF absorbs less moisture, which allows it to repel fungus, mold, and bacteria. This not only increases its durability but prevents the generation of bad odors, a quality that is highly valued in the healthcare and hospitality sectors.
Enhanced Color Retention Polyester garments and textile casings tend to have brighter and more durable colors and prints. This is a primary reason why the market for high-end shirts, blouses, and bedding is composed mostly of polyester-based materials.
Manufacturing Excellence: From PET Waste to High-Quality Fibre
The production of 7D 64mm Regenerated PSF involves a sophisticated polymerization process performed at high temperature and pressure. The raw material is sourced from PET/Polyester waste and post-consumed PET bottles, which are cleaned and transformed into high-purity flakes.
After the spinning and drawing process, the polymer becomes staple fibres when cut into the precise 64mm length. These fibres are fabricated into non-woven fabrics through compression or used as high-loft filling for a wide range of applications, including automobile interiors, construction materials, and sanitary products.
Performance Benefits for the End User
High-quality 7D 64mm HCS provides specialized performance benefits that directly impact consumer satisfaction:
Thermal Warmth Retention The hollow construction makes the fibre 20% lighter than ordinary solid fibre. It prevents air convection within the fibre to keep warm, wrapping warm air and isolating cold air to keep the body comfortable in all seasons.
Hygroscopicity and Breathability The fibre can discharge moisture quickly from the skin to keep the user dry and warm. Its special wicking effect and large surface area reduce the uncomfortable sticky feeling often associated with low-quality synthetic fills.
Soft Hand-Feel and Pendency It brings a bright, soft, and comfortable feeling to the touch. Compared with heavy thermal fabrics, the 7D 64mm HCS fabric is more easily wet, dry, and comfortable, exhibiting excellent pendency or “fall” that allows it to drape perfectly over furniture or the human body.
Industrial and Commercial Applications
Because of its high quality and consistent performance, 7D 64mm Regenerated HCS is the material of choice across several high-growth sectors:
Bedding & Home Textiles: The standard for premium pillows, blankets, comforters, and filling quilts.
Furniture Industry: Providing soft but resilient padding for sofas, chair cushions, and armrests.
Toy Manufacturing: The ideal “High Quality” filling for stuffed animals and dolls that requires a non-allergenic and soft touch.
Non-Woven Applications: Used in spray-bonded cotton, polyester wadding, and interlining for high-end apparel.
Conclusion: Sourcing 7D 64mm HCS Globally
As the global textile industry moves toward a circular economy, Regenerated 7D 64mm HCS represents the future of high-performance filling. By sourcing from experienced manufacturers in South East Asia and China, brands can ensure they are using a material that is GRS-certified, cost-effective, and technically superior.
Choosing high-tenacity regenerated PSF allows you to provide your customers with a product that is hypoallergenic, machine-washable, and environmentally responsible, ensuring long-term success in a competitive market.
