3 Denier 64MM Black Hollow Cloud Fill Staple, Springy 3D Crimp Polyester Fiber for Upholstery, Pet Beds & Dark Nonwoven

Black, cloud-like hollow filling fiber — 3D * 64 mm

This 3D * 64 mm black 3D-crimp hollow staple fiber is engineered for dark filling and nonwoven production. Color is built into the material rather than applied afterward, delivering a consistent deep black that resists fading, rubbing and bleeding through repeated washing and long display.

Specifications can be customized to match your end product and process.

Producing dark-colored filled products often runs into three recurring problems. Post-dyed black fibers fade, rub off and bleed during washing, and shade varies from batch to batch. Solid straight polyester fill feels flat, heavy and compresses permanently under use. And low-grade dark recycled staple carries uneven color, impurities and inconsistent crimp, leading to lumpy fill, shedding and weak finished products. This 3D * 64 mm black 3D-crimp hollow staple is engineered to solve those issues for dark filling and nonwoven production.

Color is built into the material rather than added afterward. Black masterbatch is dispersed through the PET melt before spinning, so the pigment exists inside the filament rather than on its surface. The result is a consistent deep black that opens, cards and fills evenly, with strong resistance to washing, rubbing and light exposure. Finished plush toys, cushions and padding do not turn grey, patchy or faded after cleaning or long display, and there is no dyeing wastewater or post-dyeing step required on the filler side.

The fiber’s comfort and shape come from two structural features working together. The three-dimensional spiral crimp makes filaments hook and interlock into springy clusters, producing volume and bounce that flat wavy fibers cannot match. The hollow core then traps air between and inside fibers, keeping the fill light, warm and buoyant while improving compression recovery. After being packed, pressed or stored, the fill loosens and returns to a fluffy state rather than staying crushed, which extends the usable life of cushions, pet beds and soft toys.

At 3D denier and 64 mm length, the fiber sits in a universal filling grade that works on both automated blow-filling lines and manual hand stuffing. The crimp keeps fibers from sliding into dense ropes, and the controlled finish allows smooth flow through nozzles and even distribution inside fabric covers. For nonwoven production, the same length and crimp card into uniform webs suitable for needle-punched, thermal-bonded and other dark structural fabrics.

Because the base material is polyester, the fill also brings practical durability: tensile strength, abrasion resistance and shape stability support heavy-duty upholstery, pet bedding and acoustic padding, not just decorative soft goods. Manufacturers can adjust the product by blending this staple with other fiber deniers or mixing hollow and solid grades to tune softness, firm support, loft height and material cost. Every batch is inspected for denier tolerance, staple length, crimp level, hollow uniformity and black shade consistency to keep production stable and defect rates low.

We supply bulk stock and provide samples for loft testing, compression recovery, color comparison, filling machine trials, wash fastness checks and nonwoven forming verification before bulk purchase. Custom denier, length, crimp density, silicone level, virgin or recycled base, and flame-retardant or antibacterial functional modifications can be arranged to match specific end products.

• Dope-Dyed Through-Body Black, Uniform Deep Color Black color masterbatch is mixed into the polymer melt before spinning, so every filament carries the same deep black across its full cross-section. There is no surface coating to peel or fade, giving consistent shade from first opening to finished product, with excellent wash, rubbing and light color fastness for dark plush, upholstery and outdoor-facing dark fill applications.
• Three-Dimensional Crimp, Springy Cloud-Like Loft The fiber is formed with a true 3D spiral crimp rather than flat wavy texture. Crimped filaments interlock naturally to build voluminous, springy clusters that bounce back after compression, producing a soft, fluffy cloud-like fill that holds its shape better than straight or flat-crimp hollow fibers.
• Uniform Hollow Core, Lightweight Warmth & High Rebound The hollow cavity traps still air inside each filament, delivering insulation and warmth at a low weight while boosting compressional resilience. Filled products stay light and buoyant rather than heavy and flat, and recover full volume after sitting, pressing or long-term storage.
• 3D Fine Denier + 64 mm Standard Staple, Smooth Filling & Web Forming The 3D denier offers a soft, balanced hand feel, while the 64 mm standard length is optimized for opening, carding, blow filling, needle punching and nonwoven web formation. The fiber distributes evenly inside covers and machines, with low fly waste and few tangles, supporting efficient automated and hand stuffing production.
• Clump-Resistant & Low Shedding, Even Fill Distribution The combination of 3D crimp and controlled surface finish keeps fibers loose and evenly dispersed, reducing hard lumps, rope-like tangles and surface shedding inside toys, cushions and padding. Finished pieces keep a smooth, full silhouette with no thin spots or uneven black patches.
• Washable & Durable, Color Stays Deep Black The stable hollow-crimp structure withstands repeated washing and drying, recovering loft quickly without matting. Because color is locked inside the fiber body, black shade remains deep and even through laundering, avoiding the fading, greying or dye bleeding common with post-dyed dark fills.
• Polyester Strength for Heavy-Duty Padding The staple retains polyester tensile strength, abrasion resistance and dimensional stability, making it suitable not only for soft toys and cushions but also upholstery underlay, pet bedding, sound-absorbing padding and industrial dark nonwovens that require durable, long-life fill.
• Ready for Blending & Custom Production It can be used as a stand-alone black fill or blended with other deniers, hollow or solid staples to adjust softness, loft, support and cost. Custom denier, length, crimp level, silicone finish and functional treatments such as flame-retardant or antibacterial finish are available on request.
