Abstract

Flame-retardant finishing represents a pivotal strategy for exploiting the application of cotton fabrics. Two novel agents were successfully synthesized: a crosslinking agent diethylenetriamine diglycidyl ether (NAED) and a flame retardant agent tris((dimethoxyphosphoryl)methyl)(hydroxymethyl) phosphonium (TDMHP). The flame-retardant cotton fabrics were successfully fabricated through covalent bonding between NAED and TDMHP, forming the CO–C bonds (NAED-cotton) and the CN bonds (NAED-TDMHP). The flame-retardant cotton exhibited exceptional performance characteristics, achieving a limiting oxygen index (LOI) of 35.8 % and a damaged length of 4.6 cm under self-extinguishing conditions. Remarkably, after 50 laundering cycles, the LOI remained at 31.1 %. Compared to control cotton, the peak heat release rate (PHRR) and total heat release (THR) showed significant reductions of 92.0 % and 32.7 %, respectively. The thermogravimetric analysis under nitrogen atmosphere represented the phosphorus-containing acid generated by the decomposition of flame retardants can catalyze the dehydration of cotton fabrics into char, improving the flame retardancy of the cotton fabrics. Specifically, the flame-retardant system shows an efficient solution to improve flame retardancy and durability, with great potential for application.

用交联阻燃体系制备耐久阻燃无甲醛棉织物

阻燃整理是开发棉织物应用的关键策略。成功合成了两种新型交联剂：二乙烯三胺二甘油酯醚（NAED）和阻燃剂三（（二甲氧基磷酰）甲基）（羟甲基）磷（TDMHP）。通过NAED与TDMHP之间的共价键形成CO-C键（NAED-棉）和CN键（NAED-TDMHP），成功制备了阻燃棉织物。阻燃棉表现出优异的阻燃性能，在自熄条件下，其极限氧指数（LOI）为35.8%，受损长度为4.6 cm。值得注意的是，在50个洗涤周期后，LOI保持在31.1%。与对照棉相比，峰值放热率（PHRR）和总放热率（THR）分别显著降低了92.0%和32.7%。氮气气氛下的热重分析表明，阻燃剂分解产生的含磷酸能催化棉织物脱水成炭，提高棉织物的阻燃性。具体而言，该阻燃体系是提高阻燃性和耐久性的有效解决方案，具有很大的应用潜力。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
