Abstract:

In order to assess the effect of magnetron sputtering on textile materials, nanometer aluminum thin film was deposited onto nylon fabric by DC magnetron sputtering at room temperature. Sample fabrics were obtained under different parameters including sputtering power and working pressure. By testing the breaking strength and breaking work of the yarn of the coated fabric, the influence of magnetron sputtering power and working pressure on the tensile properties of the yarn of the coated fabric was investigated. Compared with the original yarn’s tensile properties, all the coated yarn’s breaking tenacity was improved and its CV value was reduced, the breaking work is sensitive to the breaking elongation. With the increasing of sputtering power, both breaking work and breaking elongation decreased. At about 0.8 – 0.9Pa, the breaking work and elongation reaches their maximum values. The surface morphology of sputter coated fabric were observed by atomic force microscopy (AFM), it revealed that a complete and uniform nanometer aluminum film was formed on the nylon fabric surface.
