Pineapple pulp fiber (PAPF), also referred to as pineapple residue fiber, has emerged as a promising natural fiber with significant potential for textile applications. As a by-product of pineapple processing, PAPF represents a sustainable and eco-friendly resource that can be utilized in yarn and fabric manufacturing. Conventional yarn production commonly employs the ring spinning technique; however, spinning coarse and stiff fibers such as pineapple leaf and pulp fibers presents considerable challenges due to their rigidity and limited flexibility. Despite these limitations, PAPF has been successfully utilized in textile threads for clothing and paper production, demonstrating its versatility as a raw material.

PAPF exhibits superior mechanical properties compared to many other natural fibers. It possesses one of the highest modulus values among natural leaf fibers, comparable to high-performance synthetic fibers such as aramid and glass fibers. In addition, PAPF demonstrates excellent tensile strength, making it suitable for structural and industrial textile applications. Its relatively high fineness index and strength characteristics make it particularly suitable for producing industrial yarns and woven fabrics that require durability and dimensional stability.
