摘要
Abstract
In this paper,polyamide(PA)woven fabric was used as the base fabric,and polyurethane(PU)solution containing silica nanoparticles(PU@SiO2 NPs)was used as the coating solution to prepare composite tent fabric(PA/PU@SiO2).The morphology,structure,and durability of the tent fabric under ultraviolet(UV)radiation,water-stained,or thermal conditions were investigated.The results show that compared with PA/PU fabric without SiO2 NPs,when the mass fraction of SiO2NPs in PU coating is 5%,the air permeability of PA/PU@SiO2 fabric decreases from about 7.5 to 6.0 nm/s,while the reflectivity to UV-visible light is significantly improved.The surface wettability decreases,as indicated by the average water contact angle(WCA)on PA/PU@SiO2 remaining stable at 47° after 9 min.After thermal treatment,the PA/PU@SiO2 fabric shows superior mechanical stability.The degradation rate of the tensile strength is only 6.3%,approximately half that of the PA/PU fabric.Meanwhile,the elongation at break increases to 98.9%,compared to 61.8%for the PA/PU fabric.关键词
