摘要
针对森林防火服织物的热防护性能及舒适性能不足,对不同纤维配比、单位面积质量、单层、双层及涂层织物进行系统性的辐射热防护性能及舒适性研究,并测试了试样的阻燃性能、辐射热防护性能、透湿性能、透气性能、湿阻与热阻.结果表明,森林防火服织物的辐射热防护性能受原材料、织物结构及厚度的影响,双层织物结构因织缩不同,产生的气腔可有效地提升辐射热防护值.双层织物热阻与湿阻大于单层织物,但透气、透湿性能优于单层织物;湿阻、热阻与织物的厚度、气腔大小成正相关;阻燃硅胶涂层能显著提升织物的热防护值,但舒适性差.在轻量化森林防火服织物设计中要注重辐射热防护性能与舒适性能的平衡.
Abstract
Regarding the insufficient thermal protection and com-fort performance of forest fire‒proof clothing fabrics,a systematic study on the radiant heat protection and comfort performance of different fiber ratios,areal densities,single‒layer,double‒layer and coated fabrics was conducted,and the flame‒retardant perfor-mance,radiant heat protection performance,moisture permeabil-ity,air permeability,moisture resistance and thermal resistance of the samples were tested.The results show that the radiant heat protection performance of forest fire‒proof clothing fabrics is af-fected by raw materials,fabric structure and thickness.Due to the different crimps of the double‒layer fabric structure,the air cavi-ties generated can effectively increase the radiant heat protection value.The thermal resistance and moisture resistance of the double‒layer fabric are greater than those of the single‒layer fab-ric,but its air permeability and moisture permeability are better than those of the single‒layer fabric;moisture resistance and ther-mal resistance are positively correlated with the thickness and air cavity size of the fabric;the flame‒retardant silicone coating can significantly improve the thermal protection value of the fabric,but its comfort is poor.In the design of lightweight forest fire‒proof clothing fabrics,attention should be paid to the balance be-tween radiant heat protection performance and comfort perfor-mance.
