Abstract

This study investigates the enhancement of thermal stability and flame-retardant properties of textile materials through the incorporation of hydroxyapatite grafted with varying percentages of aminotrimethyl phosphonate (HAp–AMP). Using a MATHIS type SV manual coating machine, textiles were treated with different concentrations of AMP–HAp (2.5, 5, 10 and 20%) in a polyamide (PA) matrix. The mechanical properties, thermal stability and flame resistance of the treated fabrics were evaluated through standardized tests, including tensile strength and elongation measurements according to NF EN ISO 13934-1: 2013, thermogravimetric analysis, and flame tests per NF EN ISO 6940:2004–08. The results indicate significant improvements in the thermal and flame-retardant performance of the coated fabrics. Higher concentrations of AMP–HAp demonstrated superior resistance to thermal degradation and flame propagation, with the PA + 15 AMP–HAp sample showing the most robust performance. Scanning electron microscopy confirmed the formation of a uniform and dense coating layer, contributing to the enhanced properties. The study concludes that AMP–HAp coatings effectively improve the flame retardancy and durability of textiles, making them suitable for applications requiring high thermal and fire resistance.

彻底改变纺织品安全：HAp-AMP涂层具有先进的阻燃性和热稳定性

本研究考察了羟基磷灰石接枝不同比例的氨基膦酸三甲酯（HAp-AMP）对纺织材料热稳定性和阻燃性能的增强作用。使用MATHIS型SV手动涂布机，在聚酰胺（PA）基质中使用不同浓度的AMP-HAp（2.5%、5%、10%和20%）对纺织品进行处理。经过处理的织物的机械性能、热稳定性和阻燃性通过标准化测试进行评估，包括根据NF EN ISO 13934-1: 2013进行的拉伸强度和伸长率测量、热重分析和按照NF EN ISO 6940:2004-08进行的火焰测试。结果表明，涂层织物的耐热性能和阻燃性能有明显改善。较高浓度的AMP-HAp表现出更好的耐热降解和火焰传播能力，其中PA + 15 AMP-HAp样品表现出最强劲的性能。扫描电镜证实形成了均匀致密的涂层，有助于提高性能。该研究得出结论，AMP-HAp涂层有效地提高了纺织品的阻燃性和耐久性，使其适用于需要高耐热性和耐火性的应用。
