The fabric adaptability of DTG (Direct to Garment) digital printing has a certain range, and its performance effect is closely related to the fiber composition and organizational structure of the fabric. The following is an analysis of the main fabric types suitable for it and their characteristics：

1.Natural cellulose fabric (most suitable)
    This type of fabric is the "golden partner" for DTG printing. Because natural fibers have strong water absorption properties, they can effectively absorb water-based inks, resulting in vivid and durable printed colors with a soft feel.

▷Cotton fabric:
Includes combed cotton, carded cotton, knitted cotton (such as T-shirt fabric), and woven cotton (such as shirt fabric), etc. The higher the cotton content, the better the printing effect.
Example: Common cotton T-shirts, cotton sweatshirts, cotton and linen shirts, etc., after printing, the patterns are clear and the breathability is not affected.
▷Cotton and linen blended fabric:
Fabrics blended with linen (such as flax, ramie) and cotton. As long as the cotton content is above 70%, generally a good printing effect can be achieved.
Advantages: Retains the texture of linen, while ensuring the color of the patterns through the ink absorption property of cotton.

2. Blended fabrics with higher cotton content (more suitable)
    Blended fabrics with a cotton content of 50% - 70%, after appropriate pretreatment (such as coating), can also be compatible with DTG printing, but the effect is slightly inferior to those with high cotton content.
▷Cotton-polyester blend: 

When the polyester content is less than 30%, the ink adhesion can be improved through pretreatment, making it suitable for making casual wear, sports T-shirts, etc.
▷Cotton mixed with other natural fibers: 

Such as cotton wool blend (with low wool content), cotton silk blend, etc., the fabric's ink absorption property needs to be tested before mass production.

3. Light-colored fabrics (better than dark-colored fabrics)
    DTG printing is much more adaptable to light-colored (white, beige, light gray, etc.) fabrics than dark-colored fabrics:
▷Light-colored fabrics:

 No need for additional white ink base coat, direct printing is sufficient, color reproduction is high, and the cost is lower.
▷Dark-colored fabrics: 

A white ink base coat is required (to cover the fabric base color), followed by printing colored patterns. Higher precision of equipment and quality of ink are required, and the texture is slightly harder (the white ink layer is thicker), and only some high-end DTG models can achieve the ideal effect.

4. Unsuitable fabric types
▷High synthetic fabric: 

Such as pure polyester, nylon, polyethylene terephthalate, etc. Due to the strong hydrophobic property of the fibers, water-based ink is difficult to adhere, resulting in problems like blurred patterns and detachment (specialized synthetic fiber ink is required, but the effect is still not as good as traditional methods).
▷Thick or rough fabrics:

Such as denim (thick and with a coating on the surface), coarse woolen fabric, etc. The printer's inkjet nozzle is prone to wear and tear, and the pattern details are difficult to display.
▷Fabric with excessive elasticity: 

Such as high-stretch spandex fabric. After printing, the pattern is prone to cracking when stretched, and special treatment is required.

Summary
    DTG digital printing is most suitable for light-colored, high-linen content natural fiber fabrics (such as pure cotton T-shirts and cotton sweatshirts), followed by blended fabrics with a cotton content of 50% or more. Dark-colored fabrics, high-fiber content fabrics, and special texture fabrics should be chosen with caution or rely on technological improvements. This characteristic makes it widely applicable in personalized clothing customization and niche designer brands scenarios, but it does not have the same advantages as traditional techniques in the mass production of fiber fabric printing.
