ABSTRACT

Pineapple leaf fiber in the form of fiber bundles is present in pineapple leaves, which belongs to multicellular veins fibers. Per ton of fresh pineapple leaves can extract dry pineapple leaf fiber of 15 kg (Liu et al. 2006). Pineapple leaf fiber textile feels stiff and smooth, and it is stronger than cotton, moisture breathable, and antibacterial deodorant, so it is suitable to produce various kinds of medium and high-grade suits, shirts, dress gowns, ties decorative fabrics, etc. The chemical composition of pineapple leaf fiber is similar to other kinds of hemp fiber, its softness and spinnability are superior to those of jute, and inferior to those of ramie and linen. Research shows that pineapple leaf fiber can be used in textile processing absolutely. Currently, pure spinning yarn has been spun into 15 tex, 2l tex, blended yarn can be spun into general carded yarn and combed yarn, also spun out 30% of cotton fiber blended yarn of 25 ∼ 36 tex. However, due to its linear density being too large, the pineapple leaf fiber is not suitable to spin high-count yarn (Liu et al. 2006). At present, the extraction, degumming, and textile technology for pineapple leaf fiber have been reported in the literature, but fewer of its dyeing technology research.
