Banana fiber uses banana stems as raw material and is mainly composed of cellulose, hemicellulose and lignin. The cellulose content is lower than flax and jute, and the hemicellulose and lignin content are high, so the fiber is shiny and soft. The sex, elasticity and spinnability are slightly inferior to those of flax and jute. The fiber after chemical degumming can be used for cotton spinning. The fiber is processed by a combined treatment process of biological enzymes and chemical oxidation, and is made through drying, refining and defibration. It has the functions of light weight, good gloss, high water absorption, strong antibacterial property, easy degradation and environmental protection. Japan is at the forefront of research on banana fiber. India and other Southeast Asian countries with rich banana resources have also conducted a lot of research. China’s extraction and product development of this fiber are also in progress and have made certain progress. The successful preparation of banana fiber has greatly expanded the application of banana stems and at the same time alleviated the international shortage of natural fibers.
The development process of banana fiber products is as follows: cut the banana stem into several sections and peel it → refine it with gray juice, and then wash it with water to remove the gray juice → use bamboo scissors to clamp the soft fiber and scrape off impurities several times → soak the fiber in water, The fiber is split from the root and knotted or spliced to make a filament → twisted → warped and woven.
Banana fiber can be used to make household items, and the hand-stripped fiber can be used to produce handbags and other decorative items, or processed into yarn on jute spinning equipment to make ropes and sacks and home textiles. Because banana fiber is light, shiny and highly absorbent, it can also be made into curtains, towels, bed sheets, etc. Blended fabrics of banana fiber and cotton fiber can be woven into jeans, tennis suits, jackets, etc. The current blending rate of banana fiber is 30%. The blended fiber is a coarse yarn of 7s-12s. Fine yarns and 100% banana can be further developed. fiber. Banana fiber can also be used to make high-strength paper and packaging bags.
