Abstract

The invention discloses a finishing method of a functional coating of dyed fabric, which specifically comprises the steps of anti-dye transfer finishing, water and oil proofing finishing, polyurethane coating finishing, polyester coating finishing and calendering finishing to obtain a functional coating-finished textile. The prepared textile has a special coating product style and overcomes the problem of dye transfer caused by an organic solvent or non-ionic surfactant existing in the disperse dye; moreover, the finishing method is low in production cost, has relatively strong operability and is suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a finishing method for functional coating of dyed fabrics. Background technique [0002] Coating finishing of dyed fabrics containing polyester and nylon fibers, because the coating agent contains organic solvents or non-ionic surfactants, when the coated fabrics are treated at high temperature, the dyes inside the fibers, especially disperse dyes, will Thermal migration occurs, and the direction of thermal migration of the dye is opposite to the dyeing process of the dye, and part of the dye will re-migrate to the surface of the fiber, resulting in a significant decrease in the color fastness of the finished dyed fabric after finishing. And with the development of diversified textile coating finishing, disperse dyes not only have thermal migration phenomenon, but also solvent migration phenomenon, especially when non-polar solvents or non-ionic su...
