The pursuit of environmental friendliness, efficiency, and durability is paramount in the realm of flame retardant textile modification. Therefore, an innovative approach was designed to develop a gallic acid-derived intumescent flame retardant (GADPP), which contained reactive (-P(=O)(ONH)) and (-P(=O)(OCHCH)) groups, facilitating functional modification of lyocell fabric. The GADPP modification effectively improved both flame retardancy and ultraviolet (UV) resistance of lyocell fabric. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy has substantiated the uniform distribution and covalent bond grafting of GADPP onto the fabric. Remarkably, even after 50 laundering cycles (LCs), the limiting oxygen index and UV protection factor values of lyocell fabric modified with 30 wt% GADPP remained at 29.8 % and 117.69, respectively. These results highlighted the synergistic effect of GADPP on enhancing the flame retardancy and UV resistance of lyocell fabric. Furthermore, this multi-functional modification strategy provides a sustainable path for the enduring enhancement of flame retardant and UV protective properties in lyocell fabrics.
在阻燃纺织品改性领域，追求环保、高效和持久耐用至关重要。因此，设计了一种创新方法来开发一种源自没食子酸的膨胀型阻燃剂（GADPP），它含有反应性（-P(=O)(ONH)）和（-P(=O)(OCHCH)）基团，便于对莱赛尔纤维织物进行功能改性。GADPP 改性有效地提高了莱赛尔纤维织物的阻燃性和抗紫外线（UV）性能。傅里叶变换红外光谱、X 射线光电子能谱和扫描电子显微镜证实了 GADPP 在织物上的均匀分布和共价键接枝。值得注意的是，即使经过 50 次洗涤循环（LCs），用 30wt%GADPP 改性的莱赛尔纤维的极限氧指数和紫外线防护因子值仍分别保持在 29.8%和 117.69。这些结果突出了 GADPP 对提高莱赛尔纤维织物阻燃性和抗紫外线性能的协同作用。此外，这种多功能改性策略为持久提高莱赛尔纤维织物的阻燃性和抗紫外线防护性能提供了可持续的途径。
