Abstract
A polyamide coating slurry and its preparing method, and a process for preparing polyamide-coated fabric for printing are provided. The present disclosure provides a polyamide coating slurry for precise inkjet printing with wide applicability simple preparation steps. The surface structure and lipophilicity of the coating can be changed by mixing polyvinyl butyral and polyoxypropylene lauryl ether, urea and poly-N-isopropylacrylamide in polyamide 6, so that the adsorption properties and permeability of the coating to ink are greatly improved, and thus high-precision inkjet printing can be realized.
