The invention provides a preparation method of fibrous charcoal. The preparation method comprises the following steps: preprocessing textiles to obtain a processed object, crushing the processed object to obtain powder, and charring the powder to obtain the fibrous charcoal. The preparation method adopting waste textiles as a raw material is in favor of realizing recycling of wastes; and the preparation method improves the yield of the fibrous charcoal through preprocessing the textiles with a processing agent and adjusting the heating rate and the charring temperature in order to obtain the fibrous charcoal with high carbon content and large iodine adsorption value. 本发明提供了种纤维状生物炭的制备方法，其包括如下步骤：对纺织品进行预处理得到处理物，粉碎处理物后得到粉状物，对粉状物进行炭化得到纤维状生物炭；本发明的制备方法能够以废旧的纺织品为原料，有利于实现废物的资源化利用；另外，本发明的制备方法通过采用处理剂对纺织品进行预处理以及调节升温速率和炭化温度等措施提高了纤维状生物炭的产率，从而得到了具有较高含碳量和较大的碘吸附值的纤维状生物炭。
