Tips on distinguishing between paint printing and reactive printing and dyeing

There are two main methods commonly used for fabric printing and dyeing: one is traditional paint printing and dyeing, and the other is reactive printing and dyeing, which is opposite to paint printing and dyeing.

Paint printing and dyeing is a printing and dyeing method in which dyes are physically combined with fabrics through adhesives; reactive printing and dyeing is a dye that under certain conditions, the active gene of the dye combines with fiber molecules, the dye penetrates into the fabric, and the dye and fabric react chemically to cause the dye to bind to the fiber. form a whole.

The difference between reactive printing and dyeing and paint printing and dyeing is that the hand feel of reactive printing and dyeing is smooth and soft. A common saying is that the fabric printed with paint feels stiff and looks a bit like an ink painting effect. The reactive printed and dyed fabric looks like mercerized cotton, and the printing and dyeing effect is very good from both the positive and negative aspects.

Paint printing and dyeing characteristics

The process is simple and the cost is low. The color fastness is poor, and it will get old after washing; the environmental performance is poor, and the formaldehyde content is higher than that of reactive printing and dyeing; the printed part is sticky and appears hard without adding softener. If softener is added, the formaldehyde content will be higher.

Characteristics of reactive printing and dyeing

It has good breathability, excellent fastness and soft hand feel, but there are also problems such as cumbersome printing process, long process and difficult processing. Generally, reactive printing and dyeing can ensure that it is environmentally friendly and harmless to people. The color and fabric feel are also better, and there is no hard or soft feeling.

Identification method

recognize colors

The colors of paint printing are not bright and dull, giving people the feeling that the colors are floating on the cloth. It’s like a coat of paint on the wall.

Look at the gloss

Pigment-printed fabrics go through a “calendaring” process before leaving the factory, so you see a shiny feeling on the fabric. It may be pigment printing. This smoothness obtained by calendering is one-time and will disappear after washing. .

smell

Pigment printing adds a lot of adhesive and is directly shaped without being washed, so the finished fabric will have a strong smell.
