Reactive dyeing is also called reactive dyes. It contains active genes that can react with fiber molecules.
In the process of dyeing and printing , the active gene of the dye is combined with the fiber molecules, so that the dye and fiber form a whole. The fabric has excellent dust-proof performance, high cleanliness, and does not fade for a long time. The color is bright.
The difference with reactive printing and dyeing
There are two main methods of fabric printing and dyeing, one is traditional paint printing and the other is reactive printing and dyeing as opposed to paint printing. Reactive printing and dyeing means that azo and formaldehyde are not added during the printing and dyeing process, and it does not contain harmful substances to the human body, and does not fade during washing. The difference between reactive printing and dyeing is that the hand feel of reactive printing and dyeing is smooth and soft. The common saying is that the fabric of reactive printing and dyeing looks like mercerized cotton. The effect of printing and dyeing is very good from both the positive and negative aspects; while the fabric of coating printing and dyeing feels stiff. It looks a bit like an ink painting effect.
The fabric has excellent dust resistance, high cleanliness and high color fastness. Of course, the cost is much higher than pigment printing and dyeing. Compared with pigment printing, reactive printing has many advantages, such as good air permeability, excellent fastness, and soft hand feeling, but there are also problems such as cumbersome printing process, long process and difficult processing.
