Polyester fabric is ubiquitously applied for clothing, furniture and transportation, whereas its flammability with severe dripping often causes secondary hazards. Herein, it is highly imperative to impart excellent flame retardant to polyester fabric. In this work, a coating for polyester fabrics was prepared through a continuous dipping and ultraviolet (UV) curing process, which exhibited high-efficiency flame-retardant, anti-dripping and washing resistance. Firstly, the surface of polyester fabric was pretreated with plasma for providing more grafting sites of polyester fabric. Then, the flame retardant 6-((((2-(acryloyloxy) ethoxy) (oxo)(phenyl)phosphonio) oxy) methyl) dibenzo[c,e][1,2]oxaphosphinine 6-oxide (DPEA) and Tri(acryloyloxyethyl) phosphate (TAEP) were successfully synthesized and applied to the coating by UV-curing. In vertical burn test, the damage length of polyester with DPEA and TAEP (PET-D₃/T_4.5) was reduced from 300 mm of pristine PET to 100 mm with no dripping. In the Thermogravimetric Analysis (TGA) test, the char residue of PET-D₃/T_4.5 in nitrogen increased to 26.7 % compared with 9.7 % of pristine polyester. More specifically, the Peak Heat Release Rate (PHRR) and Total Heat Rate (THR) of PET-D₃/T_4.5 decreased 43.3 % and 22.2 % in the Micro-scale Combustion Calorimetry (MCC) test, which reflected excellent thermal stability and flame retardant properties. In addition, the Limiting Oxygen Index (LOI) of PET-D₃/T_4.5 only dripped from 24 % to 23.5 % after ten standard laundering cycles, indicating prominent water resistance. Remarkably, Thermogravimetric Analysis-Fourier transform infrared (TG-IR), Scanning Electron Microscope (SEM) and X-ray Photoelectron Spectroscopy (XPS) have been performed for investigating the mechanism of flame retardant. Thus, a strategy with convenience and economics is proposed, which is of gargantuan significance to the improvement of coating durability through plasma surface treatment and UV-curing.

涤纶织物广泛应用于服装、家具和交通工具，但其易燃性和严重滴水往往会造成二次危害。在此，赋予涤纶织物优异的阻燃性是非常必要的。在这项工作中，通过连续浸渍和紫外线 (UV) 固化工艺制备了一种聚酯织物涂层，该涂层具有高效的阻燃、抗滴落和耐洗涤性。首先，对涤纶织物的表面进行等离子体预处理，以提供更多的涤纶织物接枝位点。然后，阻燃剂 6-((((2-(丙烯酰氧基)乙氧基)(氧代)(苯基)膦基)氧基)甲基)二苯并[c,e][1,2]氧代膦6-氧化物(DPEA)和三（丙烯酰氧基乙基）磷酸酯（TAEP）成功合成并通过紫外光固化应用于涂料。₃ /T _4.5 ) 从 300 毫米的原始 PET 减少到 100 毫米而没有滴落。在热重分析 (TGA) 测试中，PET-D ₃ /T _4.5在氮气中的焦炭残留量增加到 26.7%，而原始聚酯为 9.7%。_{更具体地说，PET-D 3} /T _4.5的峰值热释放率 (PHRR) 和总热率 (THR)在微量燃烧量热法 (MCC) 测试中分别下降了 43.3 % 和 22.2 %，这反映了优异的热稳定性和阻燃性能。此外，PET-D ₃ /T _{4.5的极限氧指数（LOI）}十个标准洗涤循环后仅从 24% 滴落至 23.5%，表明防水性能突出。值得注意的是，已经进行了热重分析 - 傅里叶变换红外 (TG-IR)、扫描电子显微镜 (SEM) 和 X 射线光电子能谱 (XPS) 来研究阻燃机制。因此，提出了一种既方便又经济的策略，这对于通过等离子表面处理和紫外线固化提高涂层耐久性具有重要意义。
