辐射降温锦纶长丝及其针织物性能研究
Properties of radiative-cooling nylon filaments and their knitted fabrics
摘要
Abstract
Radiative-cooling nylon is a filament with a passive radiative cooling function and is made of high-infrared-emitting inorganic particle SiO2 and infrared-transmitting material polyamide 6(PA6)using the industrial melt spinning method.In this study,the surface morphology,aggregated structure,chemical composition,mechanical properties,thermal properties,and surface friction properties of three types of radiative-cooling nylon filaments and an ordinary nylon filament were compared.The thermal conductivity,cool feeling at instant contact,and indoor cooling performance of the four knitted fabrics were further tested.The results show that the knitted fabric interwoven with the radiative-cooling PA6/PE sheath-core composite yarn,which is spun with SiO2-added radiative-cooling PA6 as the skin material and polyethylene(PE)as the core material,and radiative-cooling nylon filament with circular cross-section demonstrate the best thermal conductivity and cooling performance.Its infrared thermal imaging temperature was approximately 1.8℃ higher than that of the ordinary nylon knitted fabric,indicating that the knitted fabric exhibits a higher infrared transmittance and better cooling effect.Thus,the radiative-cooling nylon knitted fabric possesses excellent radiative cooling performance and wearability and can be used for the development of radiative-cooling textiles.关键词
