5.5D*51mm Black Felt ES fiber For Soundproof & High Color Felt Staple Fiber Soft & Fluffy Fastness Specifications can be customized

Black ES Fiber for Felt 5.5D*51mm - Specifications can be customized

Elevate your felt manufacturing with our Black ES Fiber 5.5D*51mm - a premium low-melting bicomponent staple fiber engineered exclusively for high-performance felt production. Featuring a skin-core PE/PP structure, this fiber delivers unmatched heat-bonding capability, dispersion uniformity, and durability, making it the ultimate raw material for industrial, automotive, acoustic, craft, and packaging felt applications. Whether you produce needle-punched felt, thermal-bonded felt, or high-density specialty felt, our black ES fiber ensures consistent quality, superior performance, and end-product excellence.

• Advanced Skin-Core Bicomponent Design: The low-melt polyethylene (PE) sheath melts at 110-130°C, creating strong, flexible bonds between fibers, while the high-melt polypropylene (PP) core maintains fiber integrity and structural stability. This eliminates the need for chemical adhesives, resulting in eco-friendly, odorless felt products with exceptional bond strength.
• Precision 5.5D*51mm Specification: Uniform fineness and precisely cut 51mm length guarantee outstanding dispersion in the felt-making process. No clumping, no uneven distribution - just a smooth, dense felt matrix with enhanced tensile strength, tear resistance, and surface finish.
• Superior Black Color & Fastness: Our deep black color is masterbatch-dyed for permanent, fade-resistant performance. It retains rich color even under high-temperature processing and long-term use, ideal for black felt products requiring consistent, professional aesthetics.
• Exceptional Felt Performance: Improves felt density, softness, fluffiness, and shape retention. Produces felt with excellent sound absorption, thermal insulation, and wear resistance - perfect for automotive interiors, acoustic panels, furniture upholstery, industrial gaskets, and craft projects.
• Eco-Conscious & Cost-Effective: Non-toxic, non-irritating, and fully compliant with global environmental standards. Low processing temperature reduces energy consumption, and its compatibility with automated production lines boosts throughput and lowers manufacturing costs.

• Industrial Felt: Gaskets, seals, polishing pads, filtration media, and wear-resistant components
• Automotive Felt: Interior trim, sound deadening, insulation, and carpet underlays
• Acoustic & Insulation Felt: Soundproof panels, thermal insulation for construction & appliances
• Craft & DIY Felt: Handicrafts, decorations, coasters, packaging, and apparel accessories
• Packaging Felt: Protective padding, shock absorption, and high-end gift packaging

• 100% Virgin Raw Material: Manufactured from high-grade virgin PE/PP resins for consistent performance and purity
• Strict Quality Control: Each batch undergoes rigorous testing for fineness, length, tensile strength, dispersion, and color fastness
• Factory Direct Supply: Bulk availability, fast lead times, and customizable packaging (25kg woven bags)
• Sample Support: Free samples available for testing and quality verification
