Protective fabric has been the focus of research of the textile materials. In recent years, with the
rapid development of the robot, its protective fabric has been developed quickly. This paper is
making Al, SiO2 as the sputtering target materials, magnetron sputtering as technology, on the
back of the fabric sputtering Al layer, double-layer Al/SiO2 film, and three-layer SiO2/Al/SiO2 film
through the test of the heat reflectivity of the composite materials. As a result, the highest reflectivity of the SiO2/Al/SiO2, SiO2/Al, and single Al film is 64.97%, 57.38%, and 51.59%, respectively. It is clear that reflectivity increases with the increase of the membrane layer. In three kinds of membrane structures, there are nanometer Al particles in the formation of dense membrane
structure, which can improve the reflectivity of the fabric.
