It can also be used as an industrial filter material, sound-absorbing material, and thermal insulation material, meeting the core requirements of material strength and durability in relevant scenarios.

  • 3D*64MM HC Polyester Staple Fiber

    3D*64MM HC polyester staple fiber is a filling material that emphasizes fluffiness and warmth. Its fine fiber diameter provides superior cohesion and structural stability compared to similar silicone-containing products, allowing it to maintain its shape more effectively over time. This product retains the high loft and lightweight characteristics unique to 3D specification fibers, making it suitable for high-end insulation filling applications such as premium quilts, pillow cores, cushions, and other home textile products, as well as some high-end outdoor clothing fillings. While its softness and smoothness are slightly less than silicone-containing fibers, and its feel is firmer, this does not compromise its core warmth and fluffiness requirements, making it suitable for high-end filling applications that demand shape stability and cohesion.

  • 7D*64MM HC Polyester Staple Fiber

    7D*64MM HC polyester staple fiber is a conventional filling material that balances practicality and stability. With a moderate fiber thickness, it offers better cohesion compared to silicone fibers, resulting in a less deformable structure and superior durability. This product balances softness and support, exhibiting good loft while maintaining moderate strength. It is suitable for mid-range comforters, sofas, pillow cores, and other home textile fillings, as well as ordinary cotton clothing, autumn and winter wear, and plush toys. Compared to 3D specifications, it offers superior support and durability; compared to 15D specifications, it retains a gentler touch. While it feels slightly firmer and less smooth than silicone fibers, it strikes a balance between cost and performance, suitable for various conventional filling needs.

  • 15D*64MM HC Polyester Staple Fiber

    15D*64MM HC polyester staple fiber is a material focused on strength and functionality. It features a relatively large fiber diameter, high strength, and excellent abrasion resistance. Compared to silicon-containing fibers, it exhibits stronger cohesion and superior structural stability, making it less prone to deformation over long-term use. This product offers significantly better support than 3D and 7D specifications, but its loft and softness are relatively lower, resulting in a more noticeably stiffer feel and less smoothness. Its applications are concentrated in areas requiring high support and durability, including mattresses, sofas, and other furniture fillings; car seat fillings; automotive interior insulation such as sound insulation cotton; outdoor equipment; sleeping bags and other non-clothing thermal insulation products; and industrial applications such as filter materials and sound-absorbing materials. It is suitable for scenarios where structural stability and mechanical properties are critical requirements.

  • 4D*64HMM Polyester Staple Fiber

    4D*64HMM polyester staple fiber is optimized using specific processes, making its fiber morphology more suitable for thermal bonding. While maintaining the advantages of moderate thickness of 4D and length of 64MM, thermal bonding efficiency and bonding strength are further improved. The product has a robust structure and outstanding durability, and its adhesive-free nature ensures environmental friendliness and health. Its applications focus on scenarios with dual requirements for production efficiency and product stability, including high-efficiency textile nonwoven fabric production, mass filling of large sofas and mattresses, and standardized component processing for automotive interiors, meeting the high-performance and environmental protection needs of large-scale production.
