Embodiment Construction
[0047] The silver-sprayed fabric of the method for chemically spraying silver on fabrics in the present invention is a polyester fabric. It includes the following process steps: Ⅰ. Pre-treating the polyester fabric first, aiming to form catalytic active centers on the surface of the polyester fabric; Ⅱ. Chemically spraying silver on the fabric, aiming to deposit metallic silver on the surface of the polyester fabric. The specific route is: degreasing polyester fabric with acetone→water washing→roughening→water washing→activation→water washing→degumming→water washing→reduction treatment→water washing→neutralization→drying→spraying reduction solution→spraying silver salt solution→drying→… ...(spraying reducing solution→spraying silver salt solution→drying to form a repetition of a single process)→washing→drying.
[0048] Among them, "polyester fabric acetone degreasing→water washing→roughening→water washing→activation→water washing→degumming→water washing→reduction treatment→wat...
