Preparation method of high-fastness double-layer combined silk fibroin coated fabric

The invention discloses a preparation method of a high-fastness double-layer combined silk fibroin coating fabric. The preparation method comprises the following steps: putting a fabric substrate into a silk fibroin coating functional solvent solution for full padding, coating two sides through a scraper, forming a film in a water bath, and drying to obtain a single-layer silk fibroin coating fabric. The preparation method comprises the following steps: uniformly coating silk fibroin viscous slurry on a single-layer silk fibroin coating fabric by using a film laminating machine, and carrying out hot-pressing film forming to finally obtain a double-layer silk fibroin coating fabric, the double-layer silk fibroin coating fabric has good dry and wet rubbing fastness, and the fabric can be endowed with functionality according to requirements to meet the use in multiple scenes. 本发明公开了一种高牢度双层组合丝素蛋白涂层织物的制备方法，将织物基底置于丝素蛋白涂层功能溶剂液进行充分浸轧，通过刮刀双面涂覆，在水浴中进行成膜，烘干得到单层丝素蛋白涂层织物。后将通过覆膜机将丝素蛋白粘性浆料均匀涂覆单层丝素蛋白涂层织物后进行热压成膜，最后得到双层丝素蛋白涂层织
