What Is Garment Printing?

- May 14, 2018-

 Garment printing is a garment making process. In the first step, the fabric piece is dyed in a single color. In the second step, the pattern is printed on the fabric. The printing paste in the second step contains a strong bleach that can destroy the base dye. Therefore, this method can produce a blue-white dotted pattern cloth. This process is called whitening.

 When the bleaching agent is mixed with the dye that does not react with it in the same colorant (reduced dye belongs to this type), color printing can be performed. Therefore, when a suitable yellow dye (such as a vat dye) is mixed with a colored bleach, a blue dot pattern can be printed on the blue base fabric.

 Because the background color of garment printing is first dyed with the dyeing method, the color of the background color is richer and much deeper than if the background color is printed on the floor. This is the main purpose of garment printing.

 Garment printing fabrics can be printed by roller printing and screen printing but cannot be printed by thermal transfer printing. Because of the high production costs of the unpainted fabric compared to direct printing, the reductant required for use must also be carefully and accurately controlled. Using this type of garment printing fabric, the sales situation is better and the price is higher. Sometimes, the reducing agent used in this process can cause the fabric at the printed pattern to be damaged or destroyed.

 If the color of the front and back of the fabric is the same (because it is piece dyed), and the pattern is white or different from the background color, it can be confirmed that it is a discharge printing fabric; carefully check the reverse side of the pattern, will The traces of the original background are revealed (the reason for this phenomenon is that the chemicals that destroy the dye cannot completely penetrate the reverse side of the fabric).
