fibers obtained from the seed floss of (a perinneal plant of Gramineae native to Africa and Asia and widely distributed in tropical and subtropical regions) have potential application value in textile and other fields. At present, the biological characteristics and ecological benefits of have been extensively studied by researchers, but there have been no literature on fibers. In order to make reasonable use of fibers, their morphological structure, physical properties, chemical composition, thermal insulation properties, and surface absorption properties were explored in detail in this study. The results showed that the fiber is fine and short and has a hollow structure with a density of 0.67 g cm. Chemical analyses revealed that the main constituents of the fiber are cellulose (66.98%), hemicelluloses (13.86%), lignin (6.97%), pectin (1.99%), and wax (4.38%). The fill power and warmth retention performance of the fiber are similar to those of wool. In particular, the fiber surface has hydrophobic and lipophilic properties with a static contact angle of 123.7° for water droplets in equilibrium. Therefore, the fiber has a promising application prospect in bulk textile thermal insulation and oil-water separation fields.
从（一种原产于非洲和亚洲的禾本科多年生植物，广泛分布于热带和亚热带地区）的种子绒毛中获得的纤维在纺织等领域具有潜在的应用价值。目前，研究人员已对其生物学特性和生态效益进行了广泛研究，但关于该纤维的文献尚无报道。为了合理利用该纤维，本研究对其形态结构、物理性能、化学成分、隔热性能和表面吸附性能进行了详细探究。结果表明，该纤维细且短，具有中空结构，密度为0.67 g/cm。化学分析表明，该纤维的主要成分是纤维素（66.98%）、半纤维素（13.86%）、木质素（6.97%）、果胶（1.99%）和蜡质（4.38%）。该纤维的填充能力和保暖性能与羊毛相似。特别是，该纤维表面具有疏水亲油特性，水滴在其表面的平衡静态接触角为123.7°。因此，该纤维在大宗纺织隔热和油水分离领域具有广阔的应用前景。
