Denim can be produced by blending pineapple fiber with cotton, and its drape is similar to that of cotton denim. Pineapple fiber and spun silk can be blended into high-grade dress fabric; Various decorative fabrics and furniture fabrics can be produced with pure pineapple fiber yarn produced by rotor spinning as weft yarn and cotton or other blended yarns as warp yarn. Wool and pineapple fiber blended yarn can be spun into suit and coat fabrics by wool spinning equipment; The blended yarn of pineapple fiber and cotton produced on jute equipment can be woven into curtain cloth, bed sheets, furniture cloth, towels, carpets and so on. Polyester, acrylic fiber and pineapple fiber blended yarn produced by flax equipment can be used to produce knitted women's jackets and socks.
In addition, pineapple fiber is also widely used in industry. Pineapple fiber can be made into needle-punched nonwovens, which can be used to reinforce and protect reservoirs and river dams. Because pineapple fiber yarn has higher strength and more hairiness than cotton yarn, pineapple fiber is also an ideal material for producing V-belt core of tire cord fabric and rubber conveyor belt. Canvas made of pineapple fiber is stronger than cotton canvas of the same specification; Pineapple fiber can also be used in papermaking, strong plastics, roofing materials, ropes, fishing nets and weaving handicrafts.
At present, there are abundant pineapple fiber resources in the world, but most of them have become agricultural wastes because they have not been fully utilized. India, Japan, the Philippines and other countries have taken the lead in studying the further development and utilization of pineapple fiber, and made some breakthrough progress. Donghua University in China has studied the extraction and application of pineapple leaf fiber, and most of the research work focuses on the mechanical properties, surface modification and fiber reinforced composites of the fiber, which needs further deepening.
