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 and dyeing. 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 or shrink 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, and 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.
