When washing a four-piece suit for the first time, it is recommended to soak it in a little salt to remove the floating color on the surface (floating color is not fading, but the color on the surface of the cloth when printing and dyeing). A good four-piece suit won't fade the first time you wash it. It is suggested that the landlord buy a four-piece set of reactive printing and dyeing. The dyes in this suit contain active groups that can react with fiber molecules. In the process of printing and dyeing, the reactive groups of dyes are completely combined with fiber molecules, so that the dyes and fibers form a whole, so that the fabrics with reactive printing and dyeing are bright in color, good in color fastness and soft in hand, and the colors of home textiles with reactive printing and dyeing fabrics are not easy to wash and last as long as new. Of course, the price of this four-piece fabric is also relatively high, generally around 300, and even 7800 is better.
