Abstract

ABSTRACT The application of polyethylene terephthalate (PET) is restricted due to its high flammability and dripping phenomenon. This paper used bio-based phytic acid (PA) and gelatine (G) for flame retardant and anti-dripping treatment of PET fabric. The coated PET fabric achieved a limiting oxygen index (LOI) value greater than 29.5% and no dripping phenomenon revealing that its flame retardancy and anti-dripping properties were obviously improved. The LOI value of PA/G coated PET fabric after washing was over 26% showing good washing durability. The PA/G coating could change the starting decomposition stability and the degradation process of PET fabric and promote to form the stable char. PA/G coating formed an intumescent flame retardant (IFR) system on PET fabric to act through the IFR mechanism. This research is expected to result in a novel eco-friendly coating for flame retardant and anti-dripping thermoplastic polyester fabric.

基于生物基植酸/明胶涂层的聚对苯二甲酸乙二醇酯阻燃防滴织物

摘要:聚对苯二甲酸乙二醇酯(PET)易燃性高，有滴落现象，限制了其应用。采用生物基植酸(PA)和明胶(G)对涤纶织物进行阻燃防滴处理。织物的极限氧指数(LOI)大于29.5%，无滴落现象，阻燃性能和防滴落性能得到明显改善。涤纶/G涂层织物水洗后LOI值大于26%，洗涤耐久性好。PA/G涂层可以改变涤纶织物的起始分解稳定性和降解过程，促进涤纶织物稳定炭的形成。PA/G涂层通过IFR机理在PET织物上形成膨胀阻燃体系。这项研究有望产生一种新型的环保涂层，用于阻燃和防滴热塑性聚酯织物。
