Abstract

Aerogels, the lowest-density solids in the world, have very effective thermal insulation properties with their extremely high surface area and porous structure. Recently, there has been an increasing interest in using aerogels in the textile industry, especially to obtain functional and technical textiles. In this study, thermal and solar properties of polyester fabrics coated at different concentrations (1 %, 2 %, and 4 %) of aerogels with different particle sizes (~ 8 µm, 0 – 80 µm, 0 – 0.5 mm) were investigated. It was observed that the aerogel particle size and concentration had a significant effect on the thermal and solar properties, and the lowest thermal conductivity coefficient and thermal resistance values (0.036 W/mK and 14.33 m2 K/W, respectively) appeared at the largest particle size and maximum concentration. In contrast, the solar reflectance values of the coated samples decrease up to 62 % with increasing aerogel particle size. In a conclusion, the coating method with aerogel powders could be applied to improve the thermal insulation and solar protection properties of mainly curtains, tents, tarpaulins, and sportswear fabrics.
气凝胶粉末涂层纺织品的热、太阳能性能研究
气凝胶是世界上密度最低的固体材料,具有极高的比表面积和多孔结构,具有非常有效的保温性能。近年来,人们对在纺织工业中使用气凝胶越来越感兴趣,特别是在获得功能性和技术性纺织品方面。本文研究了不同粒径(~ 8µm, 0 ~ 80µm, 0 ~ 0.5 mm)的气凝胶在不同浓度(1%,2%和4%)下涂覆聚酯织物的热性能和太阳能性能。结果表明,气凝胶粒径和浓度对热性能和太阳能性能有显著影响,粒径最大、浓度最大时,其导热系数和热阻值最低,分别为0.036 W/mK和14.33 m2 K/W。相比之下,包覆样品的太阳反射率值随着气凝胶粒径的增大而降低高达62%。综上所述,气凝胶粉末涂层方法可用于提高窗帘、帐篷、篷布和运动服面料的隔热和防晒性能。
