The technology of silk fibroin coating is to dissolve waste silk fibroin fibers and slurry products by the solvation of an ionic solution, add a certain amount of film forming auxiliary agent and functional filler, uniformly disperse the film forming auxiliary agent and the functional filler in a high-speed stirring mode to prepare silk fibroin functional solution, and apply the silk fibroin functional solution on textiles in a single/double-sided knife coating mode to realize recycling of silk fibroin again and further play the value of the silk fibroin.

A fabric finishing process [ P ] taking silk fibroin as a medium, zhejiang province: CN105544209B, 2018-02-09.).
Because of the variability of silk fibroin, the film plating mode of all silk fibroin coatings is complicated, the obtained coating film and the coated substrate have no binding force, and the film layer is easy to crack and fall off. Meanwhile, as the coating slurry is liquid, the viscosity is low, the thickness of the coating film and the uniformity degree of the coating are difficult to adjust, and meanwhile, the coating solution is easily affected by temperature and humidity, and gel phenomenon is easily generated in the using or preserving process, so that the preparation efficiency is reduced.
