Abstract

Abstract The main aim of this research is to improve the protective thermal performance of fabrics. Flame-resistant fabrics characterizing comparable thermal properties were chosen, cotton fabric with a flame-retardant finish and Nomex® fabric. To improve thermal parameters the coating mixture, based on silica aerogel, was applied on one side of the sample surface. Parameters such as the thermal conductivity, resistance to contact, and radiant heat were determined based on the standards, which set high expectations for the protective clothing. Analysis of the coated fabrics surfaces was conducted based on confocal microscopy. It was found that the coating mixture caused a decrease in thermal conductivity. All the modified fabrics reached 1st efficiency level of protection against contact and radiant heat. The best sample from the point of view of protection against contact and radiant heat was modified cotton fabric with a flame-retardant finish. The coating mixture contained 45 wt% of silica aerogel. Moreover, better adhesion of the coating mixture to the cotton fabric compared with Nomex® fabric was observed.

二氧化硅气凝胶复合涂层在提高织物热防护性能中的应用

摘要本研究的主要目的是提高织物的热防护性能。选择了具有类似热性能的阻燃织物，具有阻燃涂层的棉织物和Nomex®织物。为了改善热参数，将基于二氧化硅气凝胶的涂层混合物应用于样品表面的一侧。导热系数、耐接触性和辐射热等参数是根据这些标准确定的，这些标准对防护服提出了很高的期望。基于共聚焦显微镜对涂层织物表面进行分析。发现涂层混合物导致热导率降低。所有改性织物都达到了防接触和防辐射热的第一级效率水平。从防止接触和辐射热的角度来看，最好的样品是具有阻燃整理的改性棉织物。涂层混合物含有45wt%的二氧化硅气凝胶。此外，与Nomex®织物相比，涂层混合物与棉织物的粘附性更好。
