Abstract

Phosphorus-nitrogen containing polymers have been attracting considerable interest as potential flame retardants (FR) for cotton fabrics. In this work, we report an experimental-theoretical joint study on flame retardancy of cotton fibres treated with ammonium ethylenediamine tetramethylenephosphonate (AEDTMP) as FR and trimethylol melamine (TMM) as binder. Through material characterization and FR test, we find that the cotton fabric samples treated with 5% AEDTMP and 5% TMM solutions exhibit better flame retardancy and durability than those with 25% AEDTMP solution by forming multilayer coatings on the fabrics. Our calculations within the density functional theory framework reveal that the P-O-C and C-O-C bonds are newly formed by reactions between the AEDTMP FR and TMM binder, and the multilayer coating enhances such binding reactions. Our work highlights that the multilayer coating with AEDTMP of lower density is superior for flame retardancy and durability of treated cotton.

摘要

含磷氮聚合物作为棉织物潜在的阻燃剂一直备受关注。在这项工作中，我们报告了一项关于用乙二胺四亚甲基膦酸铵（AEDTMP）作为阻燃剂和三羟甲基三聚氰胺（TMM）作为粘合剂处理的棉纤维阻燃性的实验-理论联合研究。通过材料表征和阻燃测试，我们发现用5% AEDTMP和5% TMM溶液处理的棉织物样品通过在织物上形成多层涂层，比用25% AEDTMP溶液处理的样品表现出更好的阻燃性和耐久性。我们在密度泛函理论框架内的计算表明，AEDTMP阻燃剂和TMM粘合剂之间的反应新形成了P-O-C和C-O-C键，并且多层涂层增强了这种结合反应。我们的工作强调，低密度AEDTMP的多层涂层在处理棉的阻燃性和耐久性方面更具优势。
