Abstract
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.
聚对苯二甲酸乙二酯(PET)织物因其出色的机械强度、高弹性、抗皱性和耐磨性而被广泛应用于我们的生活中。然而,燃烧时产生的易燃性和液滴限制了它的应用。为解决这一问题,本文提出了一种具有防火、防滴落和抗紫外线性能的新型 PET 织物。首先,使用己二酰氯、9-蒽甲醇和二乙基(羟甲基)膦酸合成整理剂(AAD)。然后通过浸渍固化工艺将 AAD 添加到 PET 织物表面。经 AAD 处理的 PET 的极限氧指数(LOI)值从 19.3% 提高到 23.8%。此外,织物通过了垂直燃烧测试(VBT),且未产生液滴。织物在水洗后仍能通过垂直燃烧测试,并保持 23.3% 的 LOI 值。同时,经 AAD 处理的 PET 织物具有出色的抗紫外线性能,UPF 值高达 4318.27。经 AAD 处理的 PET 的断裂力也得到了改善。更重要的是,使用二氯甲烷可以轻松去除织物上的 AAD 涂层,并使用旋转蒸发仪进行回收,回收率高达 98.6%。回收的 AAD 还可以重新涂覆在 PET 织物上,赋予其类似的性能。这项工作提出了一种制备可回收的耐用阻燃和抗紫外线 PET 织物的新策略。
期刊介绍:
The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
