dc.abstract.enKapok fibers (Ceiba pentandra) are considered sustainable materials, but their durabilityunder stress is poorly understood. This study examined their resistance to abiotic (UVradiation, heat) and biotic (Aspergillus niger) degradation. Fibers were exposed to 100 hof UV irradiation, 100 h of heating at 104°C, and 14 days of fungal colonization, indivi-dually and combined. Changes were analyzed with scanning electron microscopy (SEM),colorimetry, Fourier-transform infrared spectroscopy (FTIR), and pyrolysis–gas chroma-tography/mass spectrometry (Py-GC/MS). Hemicelluloses and amorphous polysacchar-ides were the most vulnerable components. UV irradiation caused yellowing, surfacecracking, and oxidative lignin modification. Heat led to moderate browning, related tosugar degradation and lignin condensation. Fungal exposure caused the most severeeffects: fiber collapse, darkening, enzymatic polysaccharide depolymerization, and ligninoxidation. Sequential stresses showed synergy: UV-pretreated fibers degraded fasterunder heat or fungal attack, accelerating polysaccharide loss and lignin disruption.Overall, kapok fibers are highly susceptible to combined abiotic and biotic stress,which compromises structural integrity and long-term durability. Protective measuresagainst UV radiation and fungal colonization are crucial for reliable industrial andenvironmental applications.

dc.abstract.other木棉纤维 (Ceiba pentadra)被认为是可持续材料，但人们对其在压力下的耐久性知之甚少. 本研究考察了它们对非生物 (紫外线辐射、热量)和生物 (黑曲霉)降解的抗性. 纤维分别和组合暴露于100小时的紫外线照射、100小时的104°C加热和14天的真菌定殖.通过扫描电子显微镜 (SEM)、比色法、傅里叶变换红外光谱 (FTIR)和热解-气相色谱/质谱 (Py-GC/MS)分析变化. 半纤维素和无定形多糖是最脆弱的成分. 紫外线照射导致木质素变黄、表面开裂和氧化改性. 热量导致中度褐变，与糖降解和木质素缩合有关. 真菌暴露造成了最严重的影响: 纤维坍塌、变暗、酶促多糖解聚和木质素氧化. 连续的压力显示出协同作用: 紫外线预处理的纤维在高温或真菌攻击下降解更快，加速了多糖的损失和木质素的破坏. 总的来说，木棉纤维极易受到非生物和生物复合胁迫的影响，这会损害结构的完整性和长期耐用性. 防止紫外线辐射和真菌定植的保护措施对于可靠的工业和环境应用至关重要.
