What is the difference between active printing and paint printing?
Active printing is the use of reactive dyes to penetrate into the fabric, and the resulting printing. Paint printing is the use of paint covering the fabric above, and the formation of the printing.
Active printing with chemical printing of paint test: active printing in the strong alkali (sodium hydroxide) and the role of insurance powder will fade, but the paint will not fade. With this test will know whether it is active printing.
Paint printing refers to paint pigments (this is called a pigment rather than a dye because it is granular). It can not be made directly with cellulosic fibers. It requires an intermediate to be an adhesive to make it affixed to the fabric , So that we can imagine the adhesive to play a role in the glue. So this printed fabric will feel some stiff, and because it is posted on the above, it is possible through several times the washing, many times the friction, the pigment particles will be different degrees of fall off, the fabric is faded. Paint printing is not washed, so there may be some of the above is not conducive to the existence of the body's chemical substances, of course, some large factories are currently used in the dyeing materials have been strictly screened, or there is a certain risk of exports. So we can rest assured that use.
Active printing refers to the use of reactive dyes on the fabric pattern of the printing process, the so-called reactive dyes refers to the dye molecules with reactive groups of dyes, the dye can be with the cellulose fiber (cotton fiber) chemical reaction , So the color is more solid. This type of printing and dyeing requires a lot of water, so the fabric feel softer, because most of the reactive dyes with the fiber chemical reaction, so there is no real dye on the fabric, and more environmentally friendly and more secure. The color of this fabric no matter how many times you wash, theoretically will not fade, that is, washed the color or will be the same with the new, (of course, the sun will make it some color), said here only refers to washed color.
