Precautions For Clothing Printing

Apr 01, 2021

When the bleaching agent and the dyes that do not react with it are mixed in the same color paste (Vat dyes belong to this type), color discharge printing can be carried out. Therefore, when a suitable yellow dye (such as a vat dye) is mixed with a colored bleaching agent, a yellow dot pattern can be printed on the blue fabric.

Because the background color of clothing printing is first dyed by piece dyeing, if the background color is printed on the whole floor, the color of the background color is much richer and darker. This is the main purpose of using clothing printing.

Garment printing fabrics can be printed by roller printing and screen printing, but not by thermal transfer printing. Because the production cost of discharging fabrics is very high compared with direct printing, it is necessary to carefully and accurately control the use of reducing agents. The fabrics printed in this way have better sales and higher prices. Sometimes, the reducing agent used in this process can cause damage or destruction of the fabric at the printed pattern.

If the background color of the front and back of the fabric is the same color (because it is piece dyed), and the pattern is white or a color different from the background color, it can be confirmed that it is a discharge printed fabric; check the reverse side of the pattern carefully, it will Reveal the traces of the original background color (the reason for this phenomenon is that the chemical agent that destroys the dye cannot fully penetrate the reverse side of the fabric).
