51mm hollow polyester staple fiber is a premium filling material that combines loftiness, support, and processing adaptability, suitable for various home textiles, furniture, and industrial nonwoven products. Its medium 51mm fiber length ensures superior uniformity during opening, web formation, and blending processes. This guarantees a full, three-dimensional appearance in filled products while facilitating continuous industrial production, enhancing material processing efficiency and finished product stability.
The hollow structure imparts lightweight properties and excellent thermal insulation, while the crimped configuration delivers superior resilience and loft. This results in pillow cores, cushions, and furniture upholstery that remain soft, plump, and resistant to clumping. In nonwoven applications, 51mm staple fibers blend effectively with other fibers to form uniform, stable fiber layers. They are widely used in spray-bonded cotton, hot-air-bonded cotton, needle-punched cotton, and high-thickness batting.
