Abstract

Phytic acid's high-efficiency flame retardant and N-halamine antibacterial were synergistically applied to cotton fibers for durable antibacterial and flame retardancy. Antimicrobial flame retardant structures were characterized by H Nuclear Magnetic Resonance Spectra (NMR) and Fourier Transform Infrared Spectrometer (FT-IR). FT-IR, X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscope (SEM), Thermogravimetric (TG), Vertical Flammability Test (VFT), and Limiting Oxygen Index (LOI) were utilized to test and characterize the prepared cotton fibers. The results showed that the antibacterial flame retardant could be durably grafted on the surface of cotton fibers for a long time, and it still maintained its self-extinguishing property after 50 washing cycles, with an LOI value of 32.2 % and a damaged length of 67 mm. The NCl bond was formed by simple bleaching treatment, which exhibited excellent bacteriostatic effect, and had a significant inhibitory effect on Escherichia coli and Staphylococcus aureus, and chlorine oxide, as an antibacterial factor, could be reactivated after long-term storage and washing. Through the systematic analysis of cone calorimetry and carbon residue, it was concluded that the flame retardant mechanism of antibacterial flame retardant was mainly condensed phase. The results of the physical property analysis of cotton fibers showed that the whiteness, air permeability, flexibility, and other physical properties of cotton fibers had no obvious change, while the hydrophilicity of the finished fibers were enhanced.

植酸-卤胺作为一种新型棉纤维耐久、抗菌、阻燃体系的协同效应

将植酸高效阻燃剂与n -卤胺抗菌剂协同应用于棉纤维中，达到持久抗菌和阻燃的目的。采用核磁共振（NMR）和傅里叶变换红外光谱仪（FT-IR）对抗菌阻燃结构进行了表征。利用红外光谱（FT-IR）、x射线光电子能谱（XPS）、扫描电镜（SEM）、热重（TG）、垂直可燃性测试（VFT）和极限氧指数（LOI）对制备的棉纤维进行了表征。结果表明，该抗菌阻燃剂可长时间在棉纤维表面持久接枝，洗涤50次后仍保持自熄性能，LOI值为32.2%，损伤长度为67 mm。通过简单的漂白处理形成NCl键，具有优异的抑菌效果，对大肠杆菌和金黄色葡萄球菌有明显的抑制作用，并且氯氧化物作为抑菌因子，经过长期储存和洗涤后可以被重新激活。通过锥量热法和炭渣法的系统分析，得出抗菌阻燃剂的阻燃机理主要是缩合相。对棉纤维的物理性能分析结果表明，棉纤维的白度、透气性、柔韧性等物理性能没有明显变化，而整理后的棉纤维亲水性有所增强。

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
