In response to the new concept of green sustainability, it is necessary to expand the functionality of bio-based natural fibers (such as cotton fabrics) to replace fabrics made from fossil fuels. One potential way of achieving this is through the use of phosphorus, boron and nitrogen based organic flame retardants. This article designs a special flame retardant system with high efficiency, high durability, and enhanced fabric strength. An "H" shaped flame retardant (TBSA) is synthesized using hydroxyethyl methylene phosphate, pentaerythritol diborate, and cyanuric chloride. After simple treatment, flame retardant fabric (TBSA/Cotton) is obtained, with a LOI value of 48.8 %. Self extinguishing is completing in the vertical flame test. The high FR efficiency reflects the progressiveness of multi flame retardant elements. It is worth noting that TBSA/Cotton exhibits excellent durability and improves the strength of the fabric. This is attributed to the covalent bonding between the "H" type flame retardant and multiple cellulose molecules, which compensates for the cracks and holes at the submicroscopic scale of natural cellulose and weakens the molecular slip effect. The research results of this article provide a good opportunity for the development of biomass cellulose flame retardant materials.
为了应对绿色可持续发展的新理念，有必要拓展生物基天然纤维（如棉织物）的功能，使其能够替代源自化石燃料的纤维。实现这一目标的一种潜在方法是使用含磷、硼和氮的有机阻燃剂。本文设计了一种具有高效、高耐久性和增强织物强度的特殊阻燃体系。采用羟甲基亚磷酸酯、季戊四醇硼酸酯和三聚氰胺氯合成了一种“H”型阻燃剂（TBSA）。经过简单处理，得到阻燃织物（TBSA/Cotton），其 LOI 值为 48.8%。在垂直火焰测试中，织物能够自熄。高 FR 效率反映了多种阻燃元素的先进性。值得注意的是，TBSA/Cotton 表现出优异的耐久性，并提高了织物的强度。这归因于“H”型阻燃剂与多个纤维素分子之间的共价键合，这种键合补偿了天然纤维素亚微观尺度上的裂缝和空洞，减弱了分子滑移效应。本文的研究结果为生物质纤维素阻燃材料的发展提供了良好的机会。
