The organic fibrous material of claim 1, wherein the organic fibrous material is prepared from coconut deciduous leaves: dissolving strong base in water at the temperature of 40-50 ℃, preparing strong base solution with the concentration of 4-10%, and soaking the plant fibers in the strong base solution for 8-12 hours.
8. The organic fibrous material of claim 1, wherein the organic fibrous material is prepared from coconut deciduous leaves: in the step (VII), in the process of bleaching the fibers, natural or additional colored substances exist in the natural fibers, residues still remain after refining, the fibers can be decolored only by bleaching, and some synthetic fibers are yellowed after heat setting treatment and are also bleached, and an oxidation bleaching agent is commonly used.
9. The organic fibrous material of claim 1, wherein the organic fibrous material is prepared from coconut deciduous leaves: the oiling rate of the fibers in the step (eight) is the percentage of the dry weight of the oiling agent of the chemical fibers in the dry mass of the fibers after the oil removal agent is removed, the oil content of the fibers is closely related to the spinnability of the fibers, the fibers with low oil content are easy to generate static electricity, and the fibers with high oil content are easy to generate the adhesion phenomenon, so that the normal operation of the textile production and processing can be influenced.
10. The organic fibrous material of claim 1, wherein the organic fibrous material is prepared from coconut deciduous leaves: and (ninth) when drying, according to different methods, different temperatures are used, high-temperature airflow is adopted for rapid drying, and airflow drying is to mix wet fibers and a heat-carrying drying medium according to a solid fluidization principle to flow in a suspension state, so that moisture in the wet fibers is gasified and then taken away by the heat-carrying medium, and the purpose of drying the fibers is achieved.
