It is still a big challenge for textile industry in improving fire resistance and reducing melt dripping with minimal loss on the physical properties of polyethylene terephthalate (PET) fabrics. In this work, a highly-effective hyperbranched flame retardant (DT) was first synthesized by ester exchange without using any organic solvent. Then, the DT foam was prepared and blade coated on PET fabric to improve the fire performance. The prepared PET fabric with only 2.7% weight gain of DT was self-extinguished and did not produce any molten dripping during the vertical flammable test. The peak heat release rate and total heat release of the PET fabric sample with 19.4% DT were decreased by 42.0% and 57.1%, respectively compared with that of the control PET. Besides, the as-prepared PET fabric sample showed better physical properties such as breaking strength, vapor permeability, air permeability, antistatic property, and softness than the control PET fabric sample. The DT foam finishing process did not involve any organic solvent and consumed less water and energy compared with conventional fabric treatments. It is expected that this work provides a facile and eco-friendly strategy for fabricating flame retardant PET fabric with excellent comprehensive performances.
如何在最大限度降低聚對苯二甲酸乙二醇酯（PET）織物物理性能損失的情況下，提高阻燃性和減少熔滴，仍然是紡織工業面臨的一大挑戰。在這項工作中，首先在不使用任何有機溶劑的情況下通過酯交換合成了一種高效的超支化阻燃劑 (DT)。然后，制備 DT 泡沫并將刀片涂在 PET 織物上以提高防火性能。所制備的DT增重僅為2.7%的PET織物在垂直燃燒試驗中具有自熄性，未產生任何熔融滴落。與對照PET相比，DT為19.4%的PET織物樣品的峰值熱釋放率和總熱釋放分別降低了42.0%和57.1%。除了，所制備的PET織物樣品顯示出比對照PET織物樣品更好的物理性能，例如斷裂強度、透濕性、透氣性、抗靜電性和柔軟性。與傳統織物處理相比，DT 泡沫整理過程不涉及任何有機溶劑，消耗的水和能源更少。期望這項工作為制造具有優異綜合性能的阻燃PET織物提供一種簡便且環保的策略。
