Poly (ethylene terephthalate) (PET)fabric is widely used in our lives due to its excellent mechanical strength, high elasticity, wrinkle resistance, and anti-abrasion. However, the inflammability and droplets produced during combustion restricted its application. Herein, a novel PET fabric with fire resistance, anti-dripping, and UV resistance is proposed to resolve this problem. Firstly, the finishing agent (AAD) was synthesized using adipoyl chloride, 9-anthracenemethanol, and diethyl(hydroxymethyl)phosphonate. Then AAD was introduced to the surface of PET fabric by dip-pad-cure process. The limiting oxygen index (LOI) value of AAD-treated PET enhanced to 23.8% from 19.3%. Besides, the fabric passed the vertical burning test (VBT) with no droplets generated. The fabric could still pass the VBT and maintain an LOI value of 23.3% after washing. Meanwhile, the AAD-treated PET fabric showed outstanding UV resistance with a high UPF value of 4318.27. The breaking force of AAD-treated PET was also improved. More importantly, the AAD coating could be easily removed from the fabric using dichloromethane and recycled using a rotary evaporator with a recovery rate of 98.6%. The recycled AAD could also recoated on the PET fabric to impart similar properties. This work proposed a novel strategy to prepare durable flame retardant and UV-resistant PET fabrics with recyclability.


聚對苯二甲酸乙二醇酯 (PET) 織物因其優異的機械強度、高彈性、抗皺性和抗磨損性而在我們的生活中得到廣泛應用。然而,燃燒過程中產生的易燃性和液滴限制了其應用。在此,提出了一種具有防火、抗滴落和抗紫外線的新型 PET 織物來解決這個問題。首先,使用二泊酰氯、9-蒽甲醇和二乙基(羥甲基)膦酸鹽合成整理劑 (AAD)。然后通過浸漬墊固化工藝將 AAD 引入 PET 織物表面。AAD 處理的 PET 的極限氧指數 (LOI) 值從 19.3% 提高到 23.8%。此外,織物通過了垂直燃燒測試 (VBT),沒有產生液滴。織物在洗滌后仍可通過 VBT 并保持 23.3% 的 LOI 值。同時,AAD 處理的 PET 織物表現出出色的抗紫外線性,UPF 值為 4318.27。AAD 處理的 PET 的斷裂力也有所提高。更重要的是,AAD 涂層可以使用二氯甲烷輕松從織物上去除,并使用旋轉蒸發器回收,回收率為 98.6%。回收的 AAD 也可以重新涂覆在 PET 織物上,以賦予類似的性能。這項工作提出了一種制備具有可回收性的耐用阻燃和抗紫外線 PET 織物的新策略。
