Brown low melt PSF is a functional fiber specifically designed for nonwoven fabrics, composite materials, and filling products. Its low melting point enables rapid softening during thermal processing, facilitating efficient bonding with other fibers to form stable, compact structural layers. This significantly enhances the material's overall strength, durability, and shape retention. The naturally brown fiber exhibits a deep, rich appearance without requiring additional dyeing, making it ideal for opaque layers, dark substrates, or applications demanding natural color tones. This eliminates the cost and environmental burden associated with dyeing processes.
Brown low melt polyester staple fiber exhibits excellent openability and moderate crimp, facilitating easy blending with polyester, cotton fibers, and regenerated fibers. It is suitable for spray-bonded cotton, needle-punched cotton, hot-air-laid cotton, composite sheets, furniture batting, automotive interior substrates, and other industrial nonwovens. With its stable thermal bonding properties, natural dark appearance, and excellent processing adaptability, this fiber delivers comprehensive solutions that balance structural strength and aesthetic requirements for home textiles, furniture, automotive interiors, and diverse industrial applications.
