Reactive dyeing is the dye under certain conditions, the active dye of the dye binds with the fiber molecule, the dye penetrates into the fabric, the dye and the fabric chemically react to make the dye and the fiber form a whole; the coating and dyeing of the dye is the physical binding of the dye through the adhesive and the fabric The printing and dyeing method. The difference between active dyeing and coating printing and dyeing is that the active printing and dyeing feels soft and smooth. The common saying is that the active printing and dyeing fabrics look like mercerized cotton. The printing and dyeing effects are good from both positive and negative perspectives; while the fabrics used for coating and dyeing are stiff, It looks a bit like ink painting effect. 1 Coating and dyeing features The process is simple and the cost is low. The color fastness is poor, and the old one is washed once; the environmental protection performance is poor, the formaldehyde content is higher than the active printing and dyeing; the printing part is sticky, and if it is not added with a softener, it becomes harder. If softeners are added, the formaldehyde content is higher. 2 characteristics of active printing and dyeing It has good air permeability, excellent fastness, and soft hand, but it also has the problems of cumbersome printing process, long process flow and difficult processing. The general active printing and dyeing can ensure that the environment is harmless to humans, and the color and fabric feel better, and there will be no hard and soft feeling. 3 identification methods Color: The color of paint printing is not bright and the color is dark, giving a feeling that the color is floating on the surface of the cloth. It's like brushing a wall of paint. Look at the luster: Paint printing fabrics have undergone a “calendering†process before leaving the factory, so everyone sees a glossy feel on the surface of the fabric, which may be a paint print. This finish obtained by calendering is disposable, after washing Will disappear. Smell smell: paint printing plus a lot of adhesive, without water treatment directly set, so the finished fabric will have a stronger taste. Feeling Feel: The paint printing is hard to feel. In order to cover this shortcoming, fabricators add a softener when setting, and the finished product will feel softer after “calenderingâ€. Most of the products will fall off after being washed.
